Engine Treatment Testimonials
2009 Chevy Traverse - 336,265 Miles ⭐⭐⭐⭐⭐
"3 weeks and 945 miles after adding Cerma engine treatment, my motor is running better than it has in years. It just seems to get better everyday. Finally a product that delivers real results."
— Mike, Sugar Hill, GA
1997 Chevrolet C1500 V8 Silverado ⭐⭐⭐⭐⭐
"Excellent product with positive result for gas mileage improvement of 15% from 15 to 17 miles on the 1997 Chevrolet C1500 V8 Silverado I am driving. Smooth idle also."
— Kuocheng S.
High Mileage Daily Driver - 90,000 Miles ⭐⭐⭐⭐⭐
"I drive 1½ hrs to work and that first trip my engine felt smoother and quicker than it ever did. My vehicle has 90k miles on it and I got 2½ mpg better than I've gotten for a couple years now. A couple weeks later and about 1000 miles more - I get anywhere between 3-5 mpg better than I've got since my rig was new. Amazing stuff. My engine runs smoother and more power for sure."
— Blaine B.
1999 Ford Power Stroke Diesel - 240,000 Miles ⭐⭐⭐⭐⭐
"I had my 1999 Ford Power Stroke Diesel engine treated with the Cerma Advanced Lubrication Technology and immediately noticed a reduction in blow by. The engine has 240K miles on it, and was beginning to show some signs of wear, which have been reduced with the treatment. An additional improvement has been that the engine runs about 20 degrees cooler in use, and seems to have regained some of its old pickup."
— Joe & Mike
VW Diesel & Kubota Tractor - Long-Term Results ⭐⭐⭐⭐⭐
"I have used this diesel treatment several times. The first was in a VW diesel that accidentally had gasoline put in it. After that it used some oil but a treatment of Cerma stopped that and we put another 90k miles on it. The other was a Kubota diesel in a lawnmower. Several times it was overheated but the Cerma treatment slowed the oil consumption considerably. Still running smoothly after 23 years."
— Rll, Pioneer, LA
5+ Years Customer ⭐⭐⭐⭐⭐
"Been using Cerma products for 5 plus years, very happy with every product I've used. Engines run smoothly and get better mileage. Oil changes are fewer. Every product has worked beyond my expectations. I share information with others every time the subject comes up."
— Les, Carson City, CA
Transmission Treatment Testimonials
2008 Hummer H2 - 120,000 Miles ⭐⭐⭐⭐⭐
"I had a small hammer in the transmission on my 2008 Hummer H2. Added Cerma transmission fluid and in about 2 weeks or about 100 miles it seems like a new transmission. I am totally amazed how great this product works - my transmission is smooth and powerful. I have 120,000 miles on tranny. Awesome!"
— Michael L.
Transmission Valve Body Fix ⭐⭐⭐⭐⭐
"2 oz Cerma auto transmission treatment corrected solenoid tolerances on transmission valve body. Magic!"
— Englewood, FL
Manual Transmission & Differential ⭐⭐⭐⭐⭐
"Great product, felt a difference 15-20 minutes after driving it per the instructions. Also tried the manual transmission and differential treatment. Feels like a new powertrain!! Torquey and smooth."
— Andrew Scrivani
A/C and Refrigeration Testimonials
1999 Ford Pickup - A/C System ⭐⭐⭐⭐⭐
"My 1999 Ford pickup truck has a very good A/C system, so I didn't think that the Cerma Advanced Lubrication technology would help it. After installation of the treatment, I watched it drop the dash outlet temperature 10 degrees and was amazed that a really well operating system could be affected by a reduction in friction that much. THANKS for the FRIDGID air!"
— Pat Gaddy, I Can Fix That!
Restaurant A/C and Ice Machine - Bonita Springs, FL ⭐⭐⭐⭐⭐
"I own a restaurant in Bonita Springs Florida and Joe treated my air conditioner, Ice Machine and other units with Cerma Blue Ice. A few days later, my Restaurant felt much cooler and less humid. What really impressed me was after four days my ice machine was producing the same amount of ice in four hours that usually took 12 hours to make. I have no worries now of running out of ice and cooling down my restaurant."
Customer Service & Overall Experience
Classic and Modern Vehicles ⭐⭐⭐⭐⭐
"Great products and great customer service!! Have used Cerma products in all my vehicles for years. Service is always faster than expected and the products are the best I've used in both modern and classic vehicles."
— Neil McCullough, Allentown, PA
