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

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.

1st attempt to test this Cerma engine treatment on my 01 Accord V6 - org 68,000mi on SEP-02 2015. Brand new Mobile 1 full synthetic oil w/ Honda genuine filter before engine treatment applied, this accord runs avg mpg 18 / 24. Engine seems quieter after 80+ miles on the road. -- Spectacular Motoring via Amazon

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)

Just a quick note to tell you what Cerma has done for my trucks.

We put Cerma in the whole system of one truck with 798,000 miles, (engine {470 Detroit}, transmission, and both rear axles). Within 50 miles 95% vibrations were gone, stack smoke was all but gone, and pulling first load with 68,000 lb payload, said truck walked off from a truck carrying same load that usually out performs treated truck. Also sealed oil leak on compressor head.

Second truck treated, has 1,500,000 plus miles, was basically parked in grass retired. Compression was low enough that either had to be used to start. Front bumper had 1.5 inch vibration both ways before treatment, and mirrors would have to be held to see clearly backing up. After treatment, truck will start without either, hence more compression, less than 1/16th inch bumper vibration both ways, and mirrors do not vibrate. Minimum stack smoke.

This Cerma product is awesome stuff!

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!!!

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

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.

John,
I applied the product to my Lexus, and I could tell and real difference in power. If I can get my right foot to cooperate, I bet I’ll see fuel savings. I just wanted to let you know. REALLY COOL! --Dennis B

I am writing you today to let you know how pleased I am with your product (Cerma). I have seen many products make many claims and usually there is a lot more fluff than there is results. I am the director of sales for a 500 Million dollar a year company in Minneapolis Minnesota, so I have had many people in my office making quite grandiose claims about “great” new products with little to back it up and results that are less than stellar. Being a fairly skeptical person, it took some persuading for me to give Cerma a try as the benefit claims seemed “too good to be true”. Knowing that my older vehicle (1995 Isuzu Rodeo with about 130,000 miles on it) was only getting about 14MPG, I decided to try Cerma in the late summer of 2006 in the crank case of the Rodeo. Right away (with in a minute or two) I noticed the engine seemed to run smoother and it had quicker acceleration, but “would it last?” I thought to myself. The answer was a resounding “YES”. The mileage went up to an average of 16.2MPG Read more

Just treated my 2007 Toyota Avalon with the Cerma Engine Treatment and the Cerma Transmission. Car is running smoooooth (the vibrating is down to almost zero)- thanks Cerma. The engine also had a slight miss when I accelerated. Already noticed a significant improvement and I'll let u know if it improves even further. -- Dave P. Kansas City, KS

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

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 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

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

Several tens of thousands of miles ago, I found out about Cerma Engine Treatment -- yep, I was skeptical. But talking with these wonderful folks convinced me to try it. After adding to the oil, I noticed a problem of concern: at the stop light, my car was so quiet i couldn't hear the engine running -- i had to check the RPM's to confirm. Even BETTER, my engine temperature very soon dropped a couple of notches, from "top" of the idiot thermometer image to the very bottom of it -- and, years later, it has NEVER climbed again. And the engine runs smoother .... and at about 150-200 RPM lower to achieve the same highway speed. Friends have noticed the same ..... i tell everyone. So -- what are YOU waiting for? --- John T. Humble, TX

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)

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.

Update: My 2004 TC now has 349,000 miles. At 288,000. It was using a qt of oil every 500 miles now it uses a qt at 4,000. This van has another 100,000 left easy! It runs great and is the best running cab in Myrtle Beach. Thank You Cerma!

Original: Just finished 4800 miles on the Cerma STM-3 Engine Treatment. Wow, my 298,000 mile cab was using a quart of oil every 900 miles. Now not a drop . It runs so quite, you can't hear it run !! I'm impressed! Also added the Cerma Transmission Treatment. As I service my transmissions every 35,000 miles, they are well maintained, but after the transmission treatment you sent, it is much smoother!! Wow!! I have a lot of cabbies asking me about the product. Thank you -- Wade

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)

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'm only 2 days into the treatment with 22k miles on the odo only 100 miles driven since treated and already noticing a big difference when driving it on the highway and even in the city. I must say I've been made a believer. The car feels more normal and definitely feels like it runs much smoother when really getting on the gas. As for the idling, starting to notice that it feels more 'confident' when idling now than it did before. Definitely money well spent.

I have been using Cerma products for close to two years now in my all my vehicles, tractors, excavator and dump truck. I am totally impressed with all of the products! As a result of my confidence in these products, I thought I would try the firearm foam and grease in my rifles that I use each year shooting sage rats. In late spring each year, I shoot as many as 1000 rounds through each of my 4 rifles that I take with me during this multiple day shoot. The first thing that caught my attention is when I used the foam in the barrel of my Ruger .204 rifle after I had done a thorough cleaning the week before. I was amazed at how much carbon came out of the barrel when I ran a patch through to remove the foam!! It was as if I had never cleaned the barrel. I used the grease on the bolt and was impressed again. In the past after 200 rounds through my bolt action .204, I would have to remove the bolt and clean the action as it would dry out and not chamber a new round properly. Last spring, I shot Read more

CERMA changed my old engine with 225,000 miles to a NEW engine with a power never seen. When I received the package, i opened it and i was suprised seeing the little bottle that i bought for 100 USD. When i am back to Haiti, i added the contains to my engine with 224,000 miles (Montero Sport 1998 ES I4 2.4L) immediately i feel my older engine is not the same, i got a new engine more powerful. my car is going to develop a power never seen since i bought it from Atlanta USA. This product is simply the best in this category. By Zerocool on Jan 05, 2015 via Amazon

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

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 came across the Cerma product when we were looking for metal protection from our hydrogen units in gas burning engines. I first tried the Cerma in my 97' Chevy Tahoe, which had over 185,000 miles prior to using it. After about 10-15 minutes on the freeway I noticed the temperature was running a little cooler then normal and when I stepped on the gas, the knocking/pinging sound was gone and the pick up was almost like it was years before when I first drove it. After another trip or two on the freeway I noticed the truck was running smoother and the smooth and quite pick up was the most notable advantage. On another trip through the desert on a hot day, as we were starting up through some mountains, we had the air conditioning on. Normally we would have to turn off the air as the truck would get too hot, but on this trip with the Cerma installed, the air stayed on the whole time and we were able to keep up with the newer vehicles with great pick up like the Tahoe used to be when new.

I have been using Mobil 1, Shell Helix, Castrol Edge, and now Cerma (Cerma is the best motor oil I have ever used) At first I thought it was my engines life was up, but when I tested Cerma my engine came back to life , on my second car the same thing happened. the piston rings were worn out and I had this changed, and your Cerma oil is all it will ever use.

My cars were a Mercedes SL500 12 Cylinder and Audi R8 8 Cylinder

Good afternoon,
I wanted to report your product results for my 2009 Kia Optima with 35k miles. I added a bottle to the automatic transmission and have experienced a much smoother shifting pattern. Otherwise not much to report.

I added one bottle to the engine oil and have noticed a significant decrease in engine operating noise. So much that at idle I often feel as though the engine stalled out due to lack of any noise or vibration. This is a tremendous improvement over the engine operation prior to the addition of your product. The largest single benefit seems to be an MPG improvement from 27mpg to 30 mpg which constitutes a 10% improvement.

These benefits took about 1,000 miles to really become apparent. I look forward to adding a bottle to my wife's 2003 Ford Expedition with 120k miles and I will report any changes for your records. Sincerely, --Kevin (08/05/2010, 11:59 AM)

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!

The best. Powered up my 12 year old truck -- it feels like new. I have a Ford F250, 2003 with 200,000.00 miles and in good shape, but after I used this product I felt the change -- more power, quieter, faster to respond. I feel like I have a new truck. I also did the transmission, did not feel any changes but for prevention. However, the engine treatment -- wow, right away ...recommend it to all my friends. -- Giovanni via Amazon (Verified Purchase)

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

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.

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

O ahhhhhhh mazing :) At first glance, i thought the price was a little crazy.but some in-the-know car guys that i know convinced me to give it a try, and i probably shouldn't have tried it on my only vehicle, but what the hell :D. my vehicle wasn't in bad shape (2004 silverado 5.3 v8) it had a slight tick at high rpm/high speed, i didn't make loud noises/vibration. i received the Cerma engine treatment very quickly ( fast shipment), eager to try. i used as instructed and im very impressed thus far with the results. improved pick-up, engine is quieter, ticking at high speed gone :D. i believe i will consider purchasing other Cerma products. please note this has been only the first day, will update if anything changes/improves. have a great day -- Stephen Reposted from http://www.amazon.com/Cerma-Gas-Ceramic-Engine-Treatment/dp/B00AZONLUC/ By stephen on May 23, 2013:

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.

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

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!

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

I own a trucking company and have been amazed at the results of the Cerma Engine Treatment and Cerma Motor Oils. I purchased Cerma because my older Series 60 Detroit was smoking badly, particularly when off the throttle. Even though overhauled only about a year and a half ago, the exhaust has always been smelly and the start up smokes very badly--everything has improved to such a degree it is astonishing--everything runs silky smooth---Thank You!

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 !

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 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

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!

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)

Hi, Just wanted let you know about the incredible results experienced with your Auto Transmission Treatment. I had already used the Engine Treatment around 1 ½ years ago and then added the Transmission Treatment in March 2014. When I first bought the car around 6 years ago the transmission randomly clunked a bit when stopping at lights. This clunk pretty much progressed to almost every time I stopped and was quite loud. I put the Transmission Treatment in before going on a 40 minute drive. My friend said, “If that fixes that clunk, I’ll call it a miracle.” I stopped at a couple of lights on the way and it was still clunking, however by the time I reached the 3rd set at around 15 minutes on the road, it stopped completely. Then all the remainder of the trip...zero clunk! It still happens on a rare occasion but is 95% better. It’s a miracle!
P.S.: To me, the photos below are visible proof that Cerma continuously keeps engines clean. After seeing photo (left) posted 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.

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

Just prior to winter in 2012, I used 1/3 an ounce of Cerma engine treatment in my 1999 Craftsman snow blower. In the past it was necessary to have the choke on and to let it run a bit before using, especially in really cold weather. Even at that, it sometimes took a couple attempts before it continued running enough to turn the choke off.

After treating it, I went out in minus 25 degrees Fahrenheit and just pulled on it and it started right away, without putting the choke on. Big difference! That is because the compression is higher now and with Cerma in the metal, the pistons move more freely. Easy moving pistons, and more compression, mean cold starts become easier. This is the same for any size engine and is especially relevant to our winter climate in Canada. For the outdoor enthusiasts it means this is a great treatment for their ATV’s in the summer and their Skidoos in the winter.

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)
