Update from NZ on Cerma: Hello, December last year I purchased several products from you. I changed my oil ran the vehicle for a while the added Cerma. I make a regular trip up a rather steep and long hill, a 3km climb. When I purchased the diesel van it would pull up this hill at 100kph no issues with plenty of power to spare. I noticed late last year that it was not pulling as hard. I changed the fuel filter, the air mass sensors etc. Some improvement was gained but not back to what she use to be.

I added Cerma about 4000km ago. No immediate change in the hill pulling ability. However, last week she started pulling just like it use to. I have not made any modifications since adding Cerma. It will be due for an oil change soon - I have your oil here to change with. I am more than impressed with the product to date. -- Cheers, Glen

I was your biggest skeptic. I bought the Cerma Engine Treatment because of how passionate you were about the product. It has been sitting on my toolbox for months. I put Ii t in the bike today and within an hour I noticed it working. Wish I hadn’t waited so long. What have you got for my tranny? -- Joe Matteis Branford, CT via text from CermaLube

I have used Cerma for about 4 months on different cars and one small truck.

Our 1991 Subaru was getting 19 to 20 miles per gallon when I treated the engine only and saw no increase in mileage but my wife complained about the increase in power because the car had a slow shift into third gear and acted like it was slipping. I soon treated the automatic and it slowly started shifting better and better until now it shift very crisp between all gears. I will soon drain the fluid and get the junk out. I now get 25MPG city or highway all the time. It is great

I also have a 2002 Chrysler AWD mini van. I treated the engine and saw huge power and a smooth running 3.8 in a short time. No increase in MPG. When I treated the transmission I fiiled the tank with high octane fuel and got 24.4 MPG. The best I ever got with the gas hog was 17.5. Since then I have seen a big difference with the types of fuel and the way my wife drives and the average is about 19 to 20 MPG (it depends on the fuel, Read more

Hullo John,
I bought 1 bottle of Cerma STM-3 Engine Treatment and 1 bottle of Cerma STM-3 Automatic Transmission Treatment from you in May 2008. I treated my Mitsubishi Challenger(see attachment) 4x4 engine which is a 3Ltr V6 in the engine and the transmission. I followed your recommended instructions for the run in, drained the oil out of the engine and refilled with new filter, and had the automatic transmission fluid completely replaced. This vehicle had done 260,000 kilometers and still had the original engine and transmission. It is now at 289K and had 3 further oil and filter changes, and I can tell you that the result has been nothing short of astounding. The engine was starting to smoke before I put the Cerma it in, This has disappeared completely. These engines are well known for lifter chatter. It has none of that. It is so quite, and vibration is so minimal, that my friends marvel at it when I tell them how many kilometers it has done. It has increased in power and responsiveness Read more

Hi John, I want you to know that the Cerma Transmission Treatment fixed my 25 year old BMW M6 manual tranny, which did not want to go into first gear much before. This appears to be a known issue with those Getrag gearboxes. The Cerma STM-3 Engine Treatment made this same vehicle run smoothly, like never before, and cleaned up the exhaust beyond belief. I also used the Cerma STM-3 Engine Treatment in a 1989 Chrysler Dynasty with an oil burning problem, namely valve guides worn. That problem seems to have evaporated now too, and it is running very smoothly and it's exhaust is also noticably cleaner. Regards, Glenn - via admin move 02/29/2012, 05:12 PM

What the ......, this stuff actually works!
Here's the story...1990 Mitsubishi Montero that I bought new. First it was the unofficial Cheerleading Team vehicle for my daughter and now it is the unofficial Baseball Team vehicle for my son. Currently at 144,853 miles. I was turned on to CERMA by a gear head/mechanic friend of mine who swears by this product. Honestly didn't believe him, I actually tried it to sort of prove him wrong! Engine oil treatment first. When I added the treatment the engine ran smoother and quieter, literally within minutes.

Drove the Montero like that for around 2,500 miles then did an oil change. I did the oil change myself with the aforementioned gear head/mechanic. (By the way, the oil came out very dirty as a result of the treatment cleaning the engine). Added CERMA Motor Oil and noticed more power, and even smoother running than before.

NOW HERE IS THE KICKER.......my friend had the oil that we took out tested and the test showed that I have anti-freeze Read more

GREAT product I use CERMA in EVERYTHING from my TORO push mower to both my Chevrolet vehicles with GREATLY improved gas mileage & lawn mower that runs like a "swiss watch" As long as CERMA is around I will be a Loyal customer, Thanks!

In my application, 1991 BMW 750i 5.0L 12 cylinder, I was mainly trying to correct annoying hydraulic lifter noise without having to replace any lifters. The Cerma product worked almost immediately to quiet all noisy lifters and they have remained quiet for the last 30K miles on an engine that now has 186K miles. I also notice smoother idle and overall performance, if that is possible with a 12 cylinder motor! I also used it in the tandem hydraulic pump (power steering and load leveling rear suspension systems) and power steering "groan" has greatly diminished!

Unbelievable MPG increase!! My new 2015 subaru outback 3000 miles had 27.4 miles per gallon. I added this to the oil chamber under the hood, reved the engine up to 4000 rpm's for a few minutes, then drove it hard for 30 minutes on streets and freeway mostly. It's been 8 months and this car just keeps climbing in MPG every month. I am currently getting 38.6 MPG!!! Yes I'm very impressed and honestly surprised at the results. It was worth the $$$ for sure. -- Jennifer V. via Amazon (Verified Purchase)

Bought it used in February, added the motor treatment as I left the dealer. Have averaged 41mpg since I bought it, 18% improvement over the highway rating of 35. (I commute with a total of 3 stop signs or stop lights on the way to work) Here is a copy of each fill-up since new to show I'm not making this up:
The dealer changed the oil last time, but I changed to Cermax 0-20 oil yesterday so I expect it will improve some more improvement coming. Thanks Cerma for helping me achieve some steller mpg!

I put both transmission and engine treatment in our Maxima last night,drove about 35 miles. I noticed a smoother running engine right away. Drove another 50 miles today, gas mileage is up about 2 miles a gallon. Will switch to Cerma Oil in about 3k miles. -- Sherman J. Round Rock, TX

Fuel Treatment from April 14th, 2015: Great stuff. My gas mileage definitely goes up steadily, as per my digital gauge, when I use this stuff. I absolutely love this product. My engine runs very smooth with this product. Highly recommended. -- MichiganSooner via Amazon

Transmission Treatment from Oct 26th, 2014: Had a rough (down) shifting Acura RL automatic transmission; other products helped but not past the short-term. This product worked like a charm. There is zero problem now. I could not be more pleased. -- MichiganSooner via Amazon

I treated my 1998 Dodge Diesel Pickup with 6 oz Cerma Engine| Treatment and the engine smoothed up and has much more power. I am very satisfied with this. I also put 2 oz in the transmission. The transmission was shifting rough and had a slight leak. After adding the Cerma STM-3 Transmission it shifted much smoother and also has stopped leaking. I would recommend it to people to try. – Charles Penner via admin move 02/29/2012, 05:13 PM

The amazing Cerma technology! The reason I say amazing is because I worked at Douglas Aircraft in the engineering changes on the DC-9 program way back in the early 1960’s and we had a Cerma type product that did two things, stopped friction and heat, the difference was that technology back then was kept under lock and key in a high security vault. It cost $5,000 per ounce.

I take my hat off to John Murray and the Cerma team for breaking the code of this technology and making it available to the general public for just pennies a treatment. I know by putting the One Time Cerma Treatment in my car or aircraft engine that I can double the life of my engine and save thousands of dollars in oil changes, maintenance and fuel savings. Less friction and heat is a real game changer.

My bright red Ford 150 with the chrome and tow package that I bought brand new right off of the show room floor had 120,000 miles on it when I put the Cerma Treatment in my engine and transmission. I could hear Read more

When I first went to use this product, I was a bit skeptical, I had an issue with my truck starting. I had tried every chemical to run through the gas tank claiming to "fix" rough starts, all of them failing miserably. I ran the Cerma fuel treatment through and sure enough, next day, my truck started up beautifully. That was enough to convince me to try the transmission treatment to see if it could handle the transmission issue, sure enough after running it through my transmission for a couple hundred miles, 1st to 2nd smoothed right out. Now I've got the engine treatment. This is the only liquid I've ever seen that actually not only works and does what it says, but exceeded my expectations. Excellent product! -- CJ, Danbury, CT

I used the Cerma foam treatment in the following handguns: .44 revolver, .357 revolver.40 semi, .357 sig semi and AR 15 .223 rifle so far. I am very pleased with the results of all barrels. Next shooting session only required the use of bore snakes to clean the small amount of debris. Lead staining and haloing left on the front of revolver cylinders that require a little wire brush scrubbing I use the Cerma lube for this. The spray works good on the actions. I use the lube on slide rails, slides and the outer surface of high friction areas of the barrels. I have recommended the products. -- Dale W. / DWJR Firearms Training / Rochester, MA

This is the best stuff I've ever used. I did not buy from Amazon but bought the Engine Treatment direct from the manufacturer. Now that being said, this is the best stuff I've ever used. I have a 2007 Chevy Colorado with an Inline 5 cyl. Engine. Did not know at the time I bought the truck that inline 5cyl. engines vibrate badly do to to the extra 5th cyl. and I mean really bad vibration at stop lights and especially when I first crank up in the mornings. Poured the Cerma in like it said to and no more vibration I mean right then and there immediately. I've driven about 800 miles so far and love it. So whoever said this stuff does not work is full of it. I am an ordinary guy not a paid spokesman or anything like that.

My name is ECS, i was introduced to your product by a friend. I spoke with John your technical analyst and asked him if this would be a good product for my car he said that indeed it would. I ordered one bottle of the Cerma Engine Treatment and used it in my car for approximately 500 miles before i needed a smog check . When i went to get the smog check the attendant indicated my car might not pass the test because California had changed their smog levels as of January 1, 2011 and some older cars could not pass.
So i left the car with him to check it upon my return he said the pass with flying colors and added that it was running better than when it was brand new. You can compare the results of the tests below. This product is everything it says and some.
Thanks, ECS (Ernest Strong via email Tue, Dec 6, 2011 at 2:28 PM)

This product saved me from loosing the use of my furnace for a week in December, I was leaving my home in north IA. I heard a strange noise from the basement and went to investigate, it sounded like a bad bearing, I opened the case of the furnace and it got louder, shut furnace off and noise quit , I touched the induction blower motor and it was very hot, I vent out to garage found a half empty Cerma bottle and dental syringe treated the bearings on every side I could reach worked it in by turning the gravelly feeling motor by hand until it seemed to loosen up, I reinstalled the motor and was instantly and vary noticeably better, it was working so well by the time the new one arrived, I put on the shelf for a backup. Thanks John L. , John, Mike, and Dea for introducing me to Cerma it has truly been a life saver!!!

Amazing!! This stuff really works as described and then some. I used it three 2015 GMCs (Denali 1500, Denali 2500, and Yukon XL). Smoothed out the idles , don't even know they were running, More responsive, and most importantly no lifter noise when you start them up first thing in the morning. Also increased oil pressure by 10psi. Amazing product!! Intend on putting in my fleet of dump trucks 15 liter Cummings ISX. -- Amazon Customer via Amazon (Verified Purchase)

I own a 2002 Mack semi. My truck started using 2 to 3 gallons of oil per week. I was told I needed to rebuild the motor, rings, sleeves, rod, and main bearings. The motor had an excessive amount of blow by. I added Cerma and followed the instructions carefully. Over the next three days the truck used less than a half gallon of oil. Six months latter the truck has not used any oil between oil changes, and the blow by has almost disappeared. At my last oil change I pulled an oil sample. On a million mile motor the iron should have been between 50 and 120 parts per million. A new motor should be between 30 and 40 parts per million iron. My oil sample came back 20 parts per million iron and less than 5 ppm of other wear metals. The oil sample was taken at 18,000 miles on the oil and over a month of idol time. The numbers should have been elevated based on the miles and time on the oil. I have seen a ten percent in fuel economy in all of my trucks. This is the best product you can get for your Read more

So here we are at 50,000 miles. Picture here is the cleanest intake valves ever seen on a GDI motor, by two EQUUS techs with 35 years experience between them. CERMA works. Way beyond anything.... Those of you contemplating its use, what are you waiting for. The SS turbo is going to heat up everything, CERMA AT fluids and AT treatments will enable the car to handle it in conjunction with some race quality SETRAB cooling products. Those that doubted and still won't admit it, .........Show me better, I defy you too. You can't. You won't. See you at 100K guys. -- Peter K. (aka Gaijii)

Hello John,

My Cerma Story #1) Treated a Chevy a week ago. Someone very close to me, I cannot disclose who, got out of the car today and removed some items from the back seat, pressed the all door lock button on the passenger side and went into a client’s office for an hour. When they came out, they couldn’t find their keys and thought, Oh no! I’ve locked the keys in the car and I have to call the Auto Club again and get them to open the car. Sure enough, they got to the car and looked in the passenger side and there the keys were still in the ignition. They tried three of the doors and they were locked, was about to call the auto club and thought, “I’ll try all the doors just in case”, then tried the driver’s door. Found it unlocked. They thought it strange that the drivers’ door wouldn’t have locked along with the others so got into the car and sat in the driver’s seat to remove the keys from the ignition. To their surprise, they found that the engine was still running and Read more

I am amazed at this product. I put Cerma STM-3 in my 2009 subaru imprezza and went from 33 mpg hwy. to 38 hwy! the engine seems to be so smooth you can't tell it is running! So then I put it in my 04 dodge hemi sport truck and went from 15.5 to 19.5 mpg hwy! unbelievable!! this stuff is the real deal! I will be ordering more and will treat the transmissions and a/c units and see what that will bring.

Dear Cerma, I started using your products in the summer of 2013. I travel all over the country in my 1991 Dodge D250 two wheel drive with a 5.9 L Cummins turbo diesel. I have a topper on it and drive between 57 and 60 mph when on the highway. I always fuel up the same way and avoid biodiesel when I can help it (Affects my mileage drastically). I averaged about 22 mpg before I started using Cerma engine oil. About 6 months into using the Cerma I noticed my highway mileage average coming in at around 23.4 to 23.9 mpg. A year later I was averaging 25.5 mpg. This last run I had from Ohio to Florida on consecutive tanks I averaged 27.2 mpg with a high this year of 28.1 mpg (I attribute the 28.1 to driving a almost 300 miles at 45 mph and not my usual 57 to 60 mph.). The other thing I noticed is the color of the oil on my dipstick. Before Cerma I used Shell Rotella 15w -40 and changed it every 5,000 miles. After every oil change the oil was just as black as it had been before I changed Read more

6/3/2015: John, I have been using the Cerma Evo grade oil in my 2012 Prius for over a year now an was thrilled to get 53-54 miles to the gallon. Recently, I just got lazy one day and took my Prius in to the Valvaline oil change and had them put in their top of the line fully synthetic to the car. The next six tanks of gas gave me no better than 47 m.p.g.!............Yes, that's right, the brand new clean conventional oil gave me a 6 m.p.g. reduction in gas mileage after I removed the Cerma Evo Oil. Cerma oil is in a class of one! This is the best oil I've ever used period! Thanks again! ---Steve A. (Cincinnati)

6/4/2014: John, the new technology in the EVO Motor Oil is the real deal for sure. I have seen my gas mileage increase to over 650 miles a tank in my 2012 Prius (58 M.P.G.) Each tankful of gas just got more and more miles after the EVO oil was put in and I love the ideal of having a Self-cleaning oil the Prius engine! *:) happy I will never have to go back to conventional Read more

I never bother writing reviews, however, this product is FANTASTIC!! 560 SEC Benz with 113k miles, about 30k since valves...UNBELIEVABLE!! Cold start on 1st turn of starter EVERY time, not the 4-6 turns... After the results with oil treatment, did tranny, power steering and fuel treatments... Tires squealing out of stand still when pedal punched AND chirping again into 2nd gear...with an automatic. Strongly recommend to anybody who wants increases performance and efficiency and reduces emissions and wear and tear... I went for 1st ever Cali smog test...guy was shaking his head saying these older benzs with big motors are a problem...passed with flying colors. This is product is the real deal. -- Pdidheon via Amazon

Products Used Cerma Engine Treatment, Cerma Motor Oil:
I purchased the Diesel Engine treatment after reading about it and its possible benefits. I am so happy I did. It literally did reduce vibration within seconds of pouring it in my engine. It also slightly reduced the normal 7.3l Diesel "cackle". Unbelievable product. I am now using the Diesel Motor Oil and do not plan on using anything else now or in the future. -- Vance W. Omaha, NE

I just wanted to tell you about my Volvo semi that I drive. It is a 2015 Volvo Day Cab with A/T. It now has 39,500 miles on it. I treated it at about 10K and fuel economy increased even though it was a new truck to about 4/10 mile per gallon. When the oil was changed by the company the mileage dropped about 1/10 Mile per gallon (Not Cermax Oil). When I treated the trailer axles I gained about 1/4 mile per gallon. The truck rolls better and I have noticed that when going down hill I gain 4MPH after treatment than before treatment. I checked with one of the other drivers with the same truck running the same route. I am getting even after the oil change 7.3 MPG and he is getting between 7.0 and 7.1 MPG. I also have 8 tires on the ground compared to his 4 tires on the ground. -- Chad S. Osage, Iowa

We have used Cerma in a gear box which is 1 of 2 identical units. The one
we treated was initially running 60 decrees hotter than the other one. We want them to
run at no more than 180 degrees. The manufacturing company tried changing out the
gears and in essence did everything they knew to try to make it run cooler with no
success. At this time we shutdown said gear box and treated it with 8 oz. of Cerma . Now instead of running 240 degrees like before it is down to 195 degrees
something even the manufacturer couldn’t accomplish. In the near future I will be
treating at least 4 more gear boxes to reduce wear. We feel that this is cheap insurance as if even one of these gear boxes failed we would be looking at at least $250,000 damage to our equipment.

Cerma Engine Treatment takes at total of 90 days to complete the intended process, will continue to update this post with information.

I put it in the engine oil and transmission. Transmission stopped slipping on very first drive home from work. I could not believe it!

Cerma lubrication is an advanced metal treatment that works great to reduce heat and friction in engines , drive trains and A/C compressors. The engines, drive trains, A/C compressors we have installed it in run much quieter, smoother and cooler!

Hi everyone!

This post is a "give back" I hope to help a few with this one, as so many helped me with replies on my first post. I learned much. At that time I was asking about re-powering or rebuilding the b43 Onan in my well maintained '83 BMW 318i. The reason was that it smoked FIERCELY, and overall sounded "loose." Despite those problems, it did still run with authority. Now I have resolved both those problems BEAUTIFULLY, almost without turning a bolt. My Onan hums smoother than any I have EVER heard.

OK, before I go any further, this is not a "spam" post. I bought the stuff I'll tell you about just like anybody else. I was reading on another forum about ceramic coating the insides of an engine, even old worn engines, how sweet they run after, and on and on. With that in mind, I went looking for the stuff they were talking about, an additive called cerma. Not being a big fan of additives, I paused and debated if I really wanted to spend $40 plus shipping on 2oz. of wonder goo. Read more

Before using Cerma, this car, a work car with 160K miles, would jerk every time it changed gears when you drive and the water temperature would be pointed a little over half way up the temperature gauge. I was a little skeptical before but kept reading the testimonials and watching the videos and decided to buy to see how it works.

I followed the instructions on how to add these additives to a "T" and I have to honestly say I am blown away with the results. After adding Cerma to the engine and the transmission and the fuel, and revving it for the recommended time, I took it out for a spin and drove for about 25-30 miles and before I even got to the highway, I felt the transmission shift smooth like it was a new car, and there is a noticeable power difference. I was easily passing up cars that were already going over the speed limit. But the biggest change I noticed after adding Cerma was the temperature difference. This car's normal operating temperature was a little over half the gauge Read more

December 2007 - I treated my 2002 Harley Davidson Custom Bagger motorcycle on the trip to Arkansas. The main thing that I noticed is the fuel mileage increase of at least 6 mpg. I was very happy as I was driving hard at speeds of at least 75-80 mph all day long on a 1700 mile round trip. I have now treated my suburban and my Harley, and am going to treat my inboard motor before taking it to Canada on a fishing trip. I was a skeptic but I am a believer now.

November 2007 - I have treated my suburban with over 133,000 miles and can report that my mileage has increased from around 15 mph to 18.1 the last time that I checked it. I am pleased with the results that I have seen after adding the Cerma Engine Treatment.

My car has a 1993 mustang motor and 5 speed transmission in a 1993 miata. I put both the engine additive and the gas treatment in the car at nearly the same time. The car definitely runs more smoothly. Throttle response is much improved. Oil pressure is up 5 lbs. I am very pleased. I am planning another dyno tuning in the next few months. I expect a 6 to 10 hp increase (280 rwhp now) and an equal increase torque. -- J. Dwight via Amazon (Verified Purchase)

Dear John: I had an appointment with Acura concerning an alignment. My 2000 Acura TL has 302,000.00 miles. As you remember from our phone conversation an application of the engine treatment gave me a very noticeable increase in gas mileage. But, also, the engine performed smoothly and very efficiently. When Acura technicians heard the engine (unaware of the Cerma STM-3 engine treatment I added) they could not believe with such high mileage how quiet and smoothly it performed. The technicians put the engine through a series of diagnostics and with a sense of disbelief and said it is functioning like a new engine. No appreciable knocks or vibrations etc.etc.etc. They also took it out for a road test. I never did tell them about the Cerma treatment. In short they remained stupefied as to its performance and lack of hesitation as is so customary in an over exhausted engine. -- Gerald S.

Best product yet. I am a contractor. I put a lot of miles on my trucks -- about 500,000 on one truck that I bought brand new 4 years ago. I put in Cerma after I saw a YouTube video and thought to give it a try. I was initially worried about the expense in buying the product, but almost immediately, I was impressed. Thanks Cerma for making the best damn thing yet and saving me a crap ton of money in the process.-- Colt J.

I've tried them all and Cerma is by far the best product on the market! Better fuel economy, my engine runs smother and quieter than when I had it rebuilt, you can feel the increased power through out the power curve and I fill up less than I deed prior to treating my engine and am now running the incredible EVO oil. If you want the very best for your vehicle then you need to try it out for yourself, you will not be disappointed.

Hi,
Well I have been using Cerma in my 2002 Toyota RAV-4 with 130,000kms.
And what a difference, my gas mileage has improved 15-20% avg, the engine has more power, and seems smoother. I am really surprised that such a little bottle of fluid actually made a big impact. I'm sold for life ..:)

Really quite pleased, so far I have about 400kms in usage, I plan to take it out around 900kms. The gas savings alone was such a big help, thanks guys for making something that actually made a difference in the way my car drives.
Cheers, Nick

So...I just got the oil changed to Cerma 5W30 and could feel a huge difference just starting the car up. Engine vibration in the pedal has gone almost to zero and the acceleration feels smoother. The best way to describe how it feels is by watching the test video that john put up comparing the oils. I was running mobil 1 and didn't realize how rough the engine ran compared to the new Cerma oil. After feeling this big of a difference I can't wait to feel the changes over the next 90 days.

Would recommend this to anybody who is looking to keep their engine long lasting no matter how many miles is on it. Already used on three of the four cars in our household and have noticed a smoother sound to the engine as well as increased gas mileage on each tank at least getting 50 to 60 extra miles on each full tank on the cars. -- via Amazon (Verified Purchase)

Well its finally complete,.. my VT has been engine treated, 6000 mi. ran in, and turbo treated, 6500 miles ran in. 7500 mi. can around, the "carrier" Motul which had served me well ( I'm a fan Cbrmale), was scheduled to come out and be replaced BY !!! TADAA !! CERMA oil 5w40. As I did my oil change I noticed something about the dipstick I hadn't noticed before....There was a "coating" on the entire portion of the stick which swims in the oil in the oil pan. What was really interesting about this "coating":
- I could not scrape it off.
-And its nature was extremely SLIPPERY to the touch with ones finger coated in oil. It was markedly more "slippery" than the portion of the dipstick which was uncoated. CERMA binds to wherever there is heat and or friction. CARBON CAN NEVER STICK TO A CERMA TREATED SURFACE. (YES,..our dirty GDI's,..no more build up). The oil makes carbon bind to itself rendering it salvageable in size for out filter media.

YOUR ENGINE TREATMENT IS THE BEST VALUE FOR THE MONEY AVAILABLE IN THIS OR ANY OTHER WORLD. IT WORKED SO WELL ON MY INCURABLE INTEGRA ENGINE, I ALMOST CONSIDER IT PROOF THAT WE HAVE ALIEN TECHNOLOGY. --Peter V. (Post 1 via order notes - 04/02/2011)

THIS IS ONE OF THE GREATEST PRODUCTS I HAVE EVER BOUGHT. ITS LIKE THE FENDER STRATOCASTER. THE RESULTS ARE SO GREAT I TELL EVERYONE THAT IT'S ALIEN TECHNOLOGY. YOU TURNED MY ACURA WITH A TRANSPLANTED HONDA ENGINE FROM AN ENGINE THAT WOULD CRAP OUT AT 5,000 RPMS NO MATTER HOW MUCH MONEY AND EFFORT WAS PUT INTO IT INTO A FINELY TUNED RACE CAR ENGINE!!!!!!! I LOVE YOU - I WILL ALWAYS LOVE YOU. THE PROBLEM WAS, IN FACT, DISHARMONIC RESONANCE. THE ALIENS WOULD BE PROUD OF YOU.) --Peter V. (Post 2 via order notes - 04/13/2012)

8/27/14 - FYI! I had my car at the dealer this morning for a recall service appt. My 2011 Fusion with 81k miles on the 2.5L 4 cyl duratec engine was "quieter then a brand new engine in any car found on the lot..." according to the service technician who worked on the car.

8/14/14 - When I changed to Cermax 5W20 on 7/8 I had 73,903 miles. Today, I have 80,533. This is the result of two round trip drives, one to Las Vegas, NV and recently to Albuquerque, NM. Both drives stressed the engine! I drove through extreme temperatures of 102' -104' degree heat, the a/c loading the engine, and sustaining highway speeds of 75 - 80 mph through the mountains of Colorado and Utah, and the desert of New Mexico. The engine remains quiet and runs smooth

8/3/15 - Just an update. I've not driven my car since 7/22, after returning from Vegas, a 3,400 mile trip. I'm prepping to drive now on another trek to Albuquerque on the same oil and filter. The engine sounds very quiet.

I was a skeptic, but when I added the Cerma Engine Oil Treatment to my Yanmar, the change was amazing! Within 20 minutes the engine smoothed out, became much quieter, and is clearly running much better. I can pull an extra 300-400 rpm – that means more horsepower out the shaft – without smoking from overloading the engine. I’ve also started using the fuel treatment and it seems like she’s running cleaner, too.
Thanks, Chuck W. Danvers, MA

We drive a 2005 Ford Escape that we leased new. The sticker for mileage said 19 city 22 hwy and we got an average of 20.5. We tried the cerma with stm3 over 2 years ago and have treated the engine oil 2 oz of STM-3™ metal treatment in the transmission 2 oz, STM-3™ in the differential 6 oz and the power steering 1 cap. We also have been using the STM-3™ MD at oil changes and have treated the gas with 1 oz approximately twice per year. Last summer in July we got 30 mpg and in November before the winter blend fuel we got 31. We have now tried the new STM-3™ Nano 1 oz in the oil, ½ oz in the transmission and 1 oz in the differential. We drove to Mason City checking our mileage and got 27 mpg on winter fuel. (last year on winter fuel we averaged 24 MPG) we then treated the fuel with STM-3™ Nano ½ oz, and drove the same road and miles home, checked it and with winter blend fuel we got 30.2 mpg. We can’t wait to see what it will be with summer fuel.

I think we performed a pretty significant experiment with your product today. My training officer did not return to the office but I will get more information tomorrow. We took 2 identical roof cutting carbide chain saws and had the same operator on the same roof make cuts one after the other. Both saws were clean and one was treated with your Cerma grease product. My mechanic also attended and I got this information verbally from him, report and probably a video that I requested to follow. One saw treated with the grease and the other without. The temperatures of the chain varied from 185 deg F (treated chain) to 340 Deg F (untreated) and the saw did 6 cuts straight (treated) vs. curving toward the end of the cut for the non-treated. The stuff worked pretty well. This was all verbal and I will try to tighten up the numbers etc tomorrow. Also this was done with my East Haven FD personnel and New Haven Fire personnel together which is how we have been training on some houses that I had Read more

I just want to state that other than an amazing product, this company has amazing customer service. The day after ordering my engine treatment I received a call to inform me that I did not need a full 2oz, and then they asked to change my order to a 1oz and refund a portion of my purchase. I also received a complimentary 2oz fuel treatment. Most companies would have just taken my order and my money, but this shows that these people are honest and care about what they do. Thank you Cerma. -- Tyler C.

I have purchased 2oz of CERMA engine treatment with STM-3 and got a free 2oz of Fuel Treatment. Thank you for the gift! Vehicle is: Subaru Legacy 1997 Wagon , VIN: xxxG5LJ4WG08xxx, European version, 2.0lt. Engine, AWD, NON Turbo. Mostly driven on LPG(85-90% of the time)!!!

I have just added 1oz of Fuel Treatment to half a tank (full tank is 15.9 Gallons) and only after 50km driving my very old “piston knock” was gone. Seriously, I have not yet touched the 2oz CERMA engine treatment.
This thing (Cerma Fuel Treatment) scares me, just like it is an alien technology. Considering that in March 2014, I tried a “Nano Energizer” from Korea and it only worked for a month. Now I have the “X-1R Engine Treatment Concentrate” (March 2015) and the knocking is still here, or I should now say WAS, since after Cerma Fuel Treatment, it is gone. ---Best regards, Ivo K.

CERMA is the real deal! If you follow the instructions after applying product to your oil, you will notice less noise, better fuel economy, about 1.5 miles more per gallon! Add to your dirty oil with about 2k miles before you have to change it again. This stuff works, and works very well! I am a happy customer who bought at the Cerma web site itself. -- ReachMe via Amazon
