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!

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 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.

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!!
