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)

I put Cerma Engine Treatment into our 1987 Suzuki Samurai. It completely smoothed out the idle, and improved our gas mileage by about 18% right away! Love this stuff! --Ethan M. via Facebook

Update: 4/23/15: Rocket fuel. Just wanted to say that I have now treated all three of our autos with the Engine, trans, and power steering treatments and they are running like new, if not better than new. Keep up the good work. Now I'm going to get the air cond. treatments for them and the house. Brad T.

Update: 2/25/15: I love the Cerma engine treatment. I now have 800 miles with the engine treatment and my 2007 Chevy Colorado has never ran better, and I bought it new with 13 miles on it. It purrs when I fire her up in the mornings with no vibration, and it used to vibrate bad, and what's crazy is I really thought that it was all in my head and that my truck would go back to normal after a week or so ,but it hasn't. It's only getting better. This stuff is so good I Just bought two more for our car and minivan and Three bottles of the trans. treatment. Can't wait to check them out. Thanks, Brad T.

Hello,
Just want to let you know of the positive results I have had so far: 2300 miles since Cerma was added to crankcase; oil consumption has been cut in half, from 4 quarts per month down to 2 quarts per month; slight mileage increase, about 1 mile per gallon more. Compression is far better than when I purchase the car at 93k ( I now have 148k on the odometer).
Thank you, Scott A

Hi, After 2000 miles my 2010 BMW 550i it runs better, no engine noise and 2-3 more MPG. Thanks ! -- Stephen K.

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

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)

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

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

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.

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

I used Cerma STM-3 Engine Treatment in my 2002 Toyota Sienna Minivan; Fuel mileage went up from 260 mile per tank to 355 miles extremely happy with gas saved. I also used Cerma in my 2000 Dodge Caravan SE; Fuel mileage went up from 245 miles per full tank to 350 miles now. Lastly, I tried Cerma in my 2010 Dodge Grand Caravan SE FLV; Fuel mileage went up from 235 miles per tank to 365 miles per tank. Also, I now change my oil every 4000 mile ... not 3000 miles as I used to. Thanks.... Cerma! – OKTAY TUZER (03/07/2012, 09:51 AM)

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

The boat is going over 28 MPH. Granted clean bottom and props but I don’t believe it ever went over 26ish on this boat. It is a 40 FT Meridian Yacht weighing 17 tons. Top end speed was increased about 10% and that is before we start with the CERMAX Motor Oil.

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)

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

Thanks for the emails, i am getting better gas millage in my bike, was at 39 MPG. I am now getting 43 MPG after 300 miles of riding on Cerma! --Greg J. – Wolcott, CT

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

Purchased a 1990 Buick Reatta with 143,000 miles on it. It runs great and can only run better with the Cerma products I just purchased (Cerma Engine Value Package) and based on the success of your products in my other vehicles! 1997 Toyota Avalon, 1991 Mercedes 420SEL, 1988 Cadillac Eldorado and 2006 Mercedes E350. Thank you! -- Raul Y.

Thank you John,
It was a pleasure speaking to you on behalf of your additives.I was amazed and I'm still smiling and overwhelmed with its results. Sir it’s not every day that actual owner and inventor takes the time to speak to common folks as myself. John you made me a believer and I’m honored and grateful. Once again for your time and wisdom you have a customer for life.
I remain Geraldo A. Colon a Cerma advocate and believer.

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

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.

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.

I am a journeyman machinist/machinery mechanic automotive enthusiasts with 40 years of formal and trade experience.presently I am rebuilding/upgrading a 1991 ford tempo and writing a book.during upgrade research i found about Cerma.as it is a coating, i was EXTREMELY concerned about the possibility of oil flow problems that other DIFFERENT product companies historically had.I spent 24 hours reading every word on this website AND contacted TWO people that provided testimonials. They both confirmed use and excellent results.I then grilled the inventor John Murray for hours with every conceivable problem. John patiently educated ME in this REVOLUTIONARY new technology, and addressed the inherent inadequacies of ALL known lubrication currently in use.

Finally I tested cerma in the transmission. I was informed that it would make it quieter in 20-30 seconds. Previously i had flushed ,new filter and installed the best special upgraded heavy duty fluid !

Hi John. I decided to try Cerma and my first use was in my daughter's 2002 Mazda Tribute with about 100,000 kms on it. It was running a bit rough and mileage was low 20's per gallon. I treated it and then we went on a family trip, loaded with 4 adults and full of golf clubs and luggage. We averaged 32 MPG, with lots of passing power and smoothed out idle. I have used it since in all my vehicles with more than satisfactory results, and plan on doing all of the transmissions shortly.
Regards, Tom D.

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!

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!!!

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've already used Cerma STM-3 Engine Treatment on 1 vehicle and plan to use this shipment to do a second. Great product, great support. I love this product, and keep buying it when I discover a friend or acquaintance who needs it too. Thanks! – Stephen Wild Post 2 (04/13/2012, 07:46 PM)

In addition to treating the drive train of my vehicle with Cerma, I used the product in another application with the intent of verifying its effectiveness. We know Cerma fills in the unseen inperfections on a metallic surface, but all the moving parts in a vehicle drive train are relatively massive and hidden from sight. I wanted to try it on something much less massive and more accessible to sight, sound and feel. So treated the cutter block and screen of my electric shaver with Cerma. In this application, the moving surfaces are powered by a tiny motor compared to the motor in a car or truck, and the surfaces involved are much smaller. But I thought it should still work to fill in the microscopic Read more

I am the guy who spoke with you at length and purchased some fuel treatment, oil additive and gun lube. I put the fuel and oil additives in immediately. I have also run 2 more tanks of fuel with treatment, reducing additive each time and the last tank had none applied. The bike is running great! The lifter noise seems to be lessened also.

I also put the fuel treatment in a friend's Honda 1300 Shadow that he just bought from someone who had stored it for four years. It was running poorly with lots of issues. A loud 2 into 1 collector with no baffling, no back pressure, it had to be run with the choke partially on, so it was starving for fuel. Either not jetted to the exhaust or plugged with varnish. I had to ride it from North Adams halfway down CT to his home since he had injured himself. I gave it three caps of additive and ran the tank well past reserve. Gassed up just before his house and it was running well with the choke off. -- Kurt P. - N Adams, 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. Let me put it this way I'm going to buy two more bottles for our car and minivan I like it that much. And going to buy some for my trucks transmission to. My Read more

I've read this thread for a while and decided to buy some AT treatment and 2 engine treatments yesterday. But not for my Veloster. I bought a beater truck (165K miles) for hunting and use around the house so I'm going to treat that with CERMA because why not. I'm also putting an engine treatment into my moms car that just crossed the 300k mark. I've done homework on CERMA, listened to the discussions/arguments on here, and for me the "proof" will be the difference in these 2 vehicles after the treatments. Based on that I will decide whether or not to bother putting it in my VT. ))

UPDATE:
So it's been a couple of months since I put engine treatment in my mom's (2001 Toyota Avalon) and my girlfriends car (2004 Toyota Corolla), I only told them I was doing something to their engine. After about a week my mom came to me and said that her hard shifting had disappeared and that it was smoother at idle. I drove her car myself at that point and sure enough, the quick/hard shifting had stopped. Read more

I must admit that I tend to view products with skepticism however the proof was in the data. I saw a legitimate 200 fps gain in a 16” AR-15 that would be the equivalent of having a 20” barrel, as well as a legitimate 150 fps boost in a 40 cal Sig P-229R. Now when cleaning time came around, both guns pretty much wiped clean with minimal fuss. I am looking forward to tinkering with this product and can see that it also has some potential for USPSA shooters who have to meet a minimum power floor providing extra velocity without pressure increase.

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

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)

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.

Did a test session earlier, the initial run since adding the CERMAX 5W40 oil plus the manual transmission treatment.

First thing I noticed when shifting to second was how much easier the gear went in, I actually said "Wowwww" out loud.

Second thing is that the butt dyno felt an immediate improvement in power. Throttling it only 1/3 of the way down in second gear caused the m/w to spray, invoking a verbal blessing of excrement. Boost was coming on so quickly that I had to raise the engagement point (twice) to restore some throttle linearity. I have to confess that I didn't feel much with either of the treatments (engine & nano) individually after they were added and worked in.

After adding the Cerma Motor Oil, the performance improvement is astounding. Never before have I experienced anything of the sort by merely changing the oil.

Really impressive.

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!

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

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 bought a bottle of Cerma on the recommendation of a friend at work. My 2001 Pontiac Formula had a lifter tick that I was hoping to get rid of. After putting in the Cermax and letting the engine run for 5 minutes, the tick was GONE! He later asked me if my car had more power, but with the LS1 (300HP) engine I couldn't feel any difference. But at 70mph my engine RPMs went down from a little over 1500 to 1250, so I can say that my engine is making the same power without working as hard. Getting rid of the lifter tick was worth the price alone! Thank you, Cerma!

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.

Thank you Cerma! The day I put Cerma in my engine it smoothed out my choppy idle at 800rpm. And even today it is still getting 5.5mpg to 6.0 mpg driving to the Northwest and back to the Midwest a majority of the time. I added Cerma in at 825,000 miles, now truck has 1,016,000 miles. I think my engine should have been in-framed when I first got it. But Cerma allowed me to keep running. Initial fuel mpg was 4.5-5mpg per long trips. And just the other day I averaged 5.5-6.1 driving east from From salt lake city, on I 80. My temp gauge pulling long grades loaded at 79k never got above 220°. And on level road my temp would sit at 185°. Thanks again! -- Vincent J.

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.

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 recently stopped in at my local gas station to fill up like I do twice a week when I met the attendant (Ken Briscoe). We got to talking passing time while I was filling up when Ken asked me if I had ever heard of a product called cerma. I told him that I hadn’t so Ken gave me his card with his number and the web address . Ken told me a little about the product. Being the skeptic that I am I put his card in my pocket and didn’t think much else about it until I got home that evening and emptied my pockets and found his card. I thought what the heck so I got on the net and went to the web site and after reading all the testimonials and reviewing the information my curiosity was peaked. I thought to myself, if this stuff really does what it claims to do then it’ll be worth its weight in gold. I called Ken the following day and asked him to order me two bottles of cerma engine treatment. In a few days Ken called and said that it was in so I stopped by as usual for my fill up at the Read more

Great product, Works as advertised! Used on 4 cylinder WV Passat 2001 (Diesel) and 2011 Kia Forte (Gasoline). After treating the engines with this product and driving 30 miles the cars became quieter. In addition, the engine's operating temperature decreased and after couple of months I noticed 3-5% decrease in the gas consumption. If all this really hold true in the future this product will pay itself in the next 5000 miles. For best results, make sure you follow the setup instruction. -- Gi R. via Amazon (Verified Purchase)

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

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.
