2008 Cadillac Escalade
Dear Cerma, I have attached a photo of the average MPG on the 2008 Cadillac Escalade which was treated at 183,743 Miles. At 183,901 miles, MPG average was 16.5. At 184,619 miles, MPG average was 17.0. At 184,938 miles, MPG average was 22.2. Quite a difference, impressive. The mileage now is 185,029 -- 1,286 miles after the treatment. The engine runs very Smooooth. At this point I would truthfully have to confirm the Cerma Brand Promise...Delivers! Thanks Cerma! -- Michael H.
Cerma Attends Auto Fest with Josh Borne
For a freestyle stunt rider, "heat is the biggest problem for bikes”. "Took me some time to test the product in the Kawasaki, but finally was able to try it out....definitely amazed!!! ... Dropped engine running temp by almost 20 degrees.” -- Josh Borne

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)
Dodge Ram 250
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 it. The color of the oil using the Cerma was actually worse during my first two oil changes. My oil change intervals with the Cerma is 30,000 miles and I change the filter every 10,000. This oil change coming up will be my third oil change with the Cerma and even though the oil that is currently in the truck has over 20,000 miles on it I can still see the dipstick and read it. It is not honey colored by any means, but I have never seen the dipstick so clean since I have owned this truck. My truck is a valuable tool which helps me earn my living, so I take the best care of it I can. I'll use Cerma products until they quit making them or I quit driving. Cerma is one of the few companies I have ever found that under promise and over deliver. Thanks for a fine product! -- Tom C.
Freightliner 12.7 Series 60 Detroit
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.
I recently SiC treated a 1100cc motor on a 1984 Honda v65 Sabre VF100S and began with these compression numbers:

Cylinder #1: 120/170 Cylinder #2 : 142/170 Cylinder #3 : 138/170 Cylinder #4 : 140/170

After treatment, compression improved significantly. My post-treatment numbers were:

Cylinder #1: 168/170 Cylinder #2: 172/170 Cylinder #3: 168/170 Cylinder #4: 170/170

After treating the sump with the Motorcycle treatment I drove the cycle for about an hour at middle speeds (45-55mph). The cycle, after about 5 minutes began to operate more like a new cycle. It had significantly more engine balance and harmonics. The engine idled more smoothly, and climbed up seamlessly across the middle range rpm’s. It truly smoothed out any hesitation and delay across the entire power band. I re-synced the carburetors and the idle could have been set as low as 500rpm’s. THAT’S ABOUT 600 RPM’S UNDER THE STOCK SETTING.

The 1984 Honda's also had a wet sump design for lubrication. Which meant the SiC treatment was working on the transmission and the wet clutch as well. Now when down shifting the motorcycle has a smoother down shift, and a new and lighter gear sound. The clutch also felt different. You can find a middle or 1/2 on and 1/2 off clutch setting with a smoother than ever drag to and from the clutching action. The cycles I rebuild get stainless steel brake lines and fresh fluids which tightens up the clutch action significantly making the effect of this treatment quite noticeable.

I will be adding this to all the cycles I rebuild. This is a no-brainer. The exhaust was almost entirely smoke free. With a valve adjustment coming my prediction is that there will be barely any noticeable exhaust. Which means nearly everything is burning during the combustion process.

I will be treating another 1100cc v65 Sabre and four Honda cb700sc Nighthawks over the next few months. The treatment will be applied to newly rebuilt engines as well as 32 year-old engines. It’s truly amazing! -- Robert K.
2011 Ford Fusion SE
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.

5/20/15 - A quick note to you about my experience with the 2 oz. engine treatment. I added the CERMA to my hot engine oil with the engine off because I was unable to with it running. Following the instructions, I drove the car for 20 minutes, about 25 miles combined city/highway driving and noticed an immediate sound and operational difference in the engine! It was quieter and idled so smoothly, it gave me the impression the engine was not running. WOW! I am impressed.

I am beginning this journey on a 2011 Ford Fusion, 2.5L 4 cyl engine that has used Amsoil Signature Series 5w20 for three years. This car has performed flawlessly on several long distance road trips, and I will be taking the car again on two more long trips in the coming months that will total about 6k miles combined total miles. I wanted to make sure my engine holds up and continues to deliver the 29 mpg I've been getting. I suspect (and hope) the mpg will improve over time as I continue to drive around with CERMA in the engine.

Thank you so much for talking with me the other day and answering my questions about CERMA. I do appreciate the time you spent explaining your reasons why you designed such a fantastic product and have kept it close to home! The next CERMA products I'm going to be ordering are the AC, Transmission and eventually the motor oil. I'm excited and looking forward to the long term results I experience and will keep you apprised of my experiences. Warmest Regards, --Douglas E
.357 Sig Semi
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
2015 Volvo Day Cab
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
223,000 Miles
Engine Treatment: Added CERMA and gas mileage has increased and harmonics are much better. Love to drive my car more than ever. Bought a car with over 223,000 hard miles. Added CERMA and gas mileage has increased and harmonics are much better. Love to drive my car more than ever. -- Scott S. via Amazon (Verified Purchase)

Transmission Treatment: Bought a car with over 222, 000 miles on it. Added it, and the trans works great. Still not finished yet. Much quieter and smoother. -- Scott S. via Amazon (Verified Purchase)

Fuel Treatment: Worked as advertised. Car runs smoother and got over 33 miles per gallon on a recent trip. Not bad for a v-6 with 234,000 miles on it! -- Scott S. via Amazon (Verified Purchase)

Power Steering Treatment: Worked as advertised in both cars I used it in. Especially my older Suburban with 223,000 miles. Had a pesky power steering unit that was giving me problems, but not any more! -- Scott S. via Amazon (Verified Purchase)
