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.

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 over 800 rounds without having to do anything and it worked like new still. I am totally sold on this stuff and recommend it to all my shooting buddies now. I haven't found anything close to this stuff. Try it as it will make a believer of you! -- Paul M. WA
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.

This stuff is crazy good although I need to replace injection pump on my Mack 350. This product made the truck run the best it has done for a year. Almost made me forget the pump. Suggestions for a new pump? -- Peter P. 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 and while I was driving, I could see the needle on the temperature gauge slowly drop the more I drove. I just thought that was just because the air was cooling the radiator while I was on the highway, but I pulled off the highway and came to a stop light and the temperature gauge was still reading cool. Now the gauge only reads a little over 1/4 way up the gauge even while parked and idle.
I am blown away at the results and from what I heard, its only gonna get better the more the car is driven.
I'm totally looking forward to adding Cerma to ALL my cars now. I cant wait!!
Thank you Cerma!!

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
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

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

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 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
