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 decided to try Cerma and my first use was in my daughter's 2002 Mazda Tribute with about 100,000 kms on it. It was running a bit rough and mileage was low 20's per gallon. I treated it and then we went on a family trip, loaded with 4 adults and full of golf clubs and luggage. We averaged 32 MPG, with lots of passing power and smoothed out idle. I have used it since in all my vehicles with more than satisfactory results, and plan on doing all of the transmissions shortly.

Did a test session earlier, the initial run since adding the CERMAX 5W40 oil plus the manual transmission treatment.
First thing I noticed when shifting to second was how much easier the gear went in, I actually said "Wowwww" out loud.
Second thing is that the butt dyno felt an immediate improvement in power. Throttling it only 1/3 of the way down in second gear caused the m/w to spray, invoking a verbal blessing of excrement. Boost was coming on so quickly that I had to raise the engagement point (twice) to restore some throttle linearity. I have to confess that I didn't feel much with either of the treatments (engine & nano) individually after they were added and worked in.
After adding the Cerma Motor Oil, the performance improvement is astounding. Never before have I experienced anything of the sort by merely changing the oil.

So...I just got the oil changed to Cerma 5W30 and could feel a huge difference just starting the car up. Engine vibration in the pedal has gone almost to zero and the acceleration feels smoother. The best way to describe how it feels is by watching the test video that john put up comparing the oils. I was running mobil 1 and didn't realize how rough the engine ran compared to the new Cerma oil. After feeling this big of a difference I can't wait to feel the changes over the next 90 days.
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.

Well its finally complete,.. my VT has been engine treated, 6000 mi. ran in, and turbo treated, 6500 miles ran in. 7500 mi. can around, the "carrier" Motul which had served me well ( I'm a fan Cbrmale), was scheduled to come out and be replaced BY !!! TADAA !! CERMA oil 5w40. As I did my oil change I noticed something about the dipstick I hadn't noticed before....There was a "coating" on the entire portion of the stick which swims in the oil in the oil pan. What was really interesting about this "coating":
- I could not scrape it off.
-And its nature was extremely SLIPPERY to the touch with ones finger coated in oil. It was markedly more "slippery" than the portion of the dipstick which was uncoated. CERMA binds to wherever there is heat and or friction. CARBON CAN NEVER STICK TO A CERMA TREATED SURFACE. (YES,..our dirty GDI's,..no more build up). The oil makes carbon bind to itself rendering it salvageable in size for out filter media.
The inventor of CERMA had explained to me that the CERMA engine treatment will treat the ferrous metal innards of the ENTIRE inside of the engine for its LIFE !! The CERMA NANO will treat the bushings of the turbo and any other non-ferrous components in the oil circulate. Now I had evidence in front of my face that I could relate to. Notice the two zones on the dipstick, the yellow is coated, the blue is not.
My VT (AT) would do 31-37 mpg at 58 mph on Motul. Now that I've done the complete array and the oil I'm doing 35-44 mpg at the same speed. (That's one day after oil switch over) -- Peter K. (aka Gaijii)

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)
Jay Erickson - Prior Lake Minnesota   1995 Isuzu Rodeo with 130,000 miles10/31/2013
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 (nearly 16% better mileage), and that continued tank after tank. I also did use the recommended “Maintenance Dose” after each oil change and Cerma has far exceeded my expectations; but it gets better.
When I heard about an event being hosted at Cerma Technology’s bottling facility in Northern Iowa this past spring, I decided to go down and see what else they had to offer and what might be coming, and also out of curiosity to see the planned demonstrations and see the actual tests for myself. I drove the 1995 Rodeo down to Iowa to the demonstration. I was able to speak with Everett and Dea from Cerma Industries and the products inventor John Murray while I was there and let them know what I ad seen for my self. Nick had been the person who initially got me to try Cerma so I shared my thoughts on the product with him. During our conversation I mentioned to Nick that my mileage had improved, my car ran better and the tick in my engine was basically gone.
The demonstrations put on that day were absolutely amazing to say the least. I was particularly impressed to see a chainsaw running on plain gas treated only with 1-1/4 oz. of Cerma. They were quite open with the demonstrations and actually let me put my finger into the bone dry gas tank to make sure there was no oil in the tank and they mixed the gas and Cerma right in front of me in a clear container. Needless to say when they fired it up, ran it full throttle and cut wood for 5~10 minutes without the saw seizing up or any ill effect, I was impressed. Additionally I saw no smoke coming from the saw’s exhaust verifying to me that there as no oil in the gas. I saw a few other demonstrations that were equally as impressive (seeing the Tractor on the dynamometer right in front of me gaining horse power was amazing).
I signed up for the drawings to win some Cerma for my other vehicles, but did not win. As I was getting ready to head back to Minneapolis that day, I had decided to treat my transmission to see if that would help my mileage and to treat my other vehicles. Nick personally came over to thank me for coming to the demonstration that day and that is when I mentioned my results to him and also, in that conversation, that I had not treated my transmission yet. In addition I mentioned the tick in my engine I get every once in a while. Nick asked me to wait a moment and went and got a 2 oz. Transmission treatment and a 2 oz. gas treatment and treated my transmission and put a 2oz. gas treatment right in my fuel tank. He said that the Isuzu’s can often times develop sticky valves in the upper end as they age and the Cermax in the gas tank would allow the upper end to be treated. The engine tick is gone.
I have been watching my mileage since the transmission treatment and comparing it to previous results. I am know getting 17.7MPG consistently and, on a recent trip to the cabin in Wisconsin, I went 323.95 miles on 16.116 Gallons of regular 87 octane fuel, that is an amazing 20.1MPG!!! I went from about 14MPG before Cerma to 20.1MPG on my trip and 17.7MPG consistently around town; that is net gain of 43.5% and 26.5% (respectively) in better fuel economy than I had been receiving. That doesn’t even begin to touch on the savings on maintenance or the tremendous environmental benefits of much cleaner emissions. With gas at nearly $3.00 per gallon, I can use the over $100.00 per month in savings between our now all treated 3 vehicles. The best thing is it is only about $60.00 to treat each car; after that it is only $10.00 for the maintenance dose at each oil change. That is a great deal for how much you save if you ask me.
Like I said in the beginning of this letter, a lot of products make great claims but Cerma backs it up with actual results. That rodeo now has over 142,000 miles on it, so Cerma works for the long haul, as advertised. Since then I have treated my other vehicles as well with similar great success. I am so impressed with your product that I plan to see what business opportunities are available with your company.
You have earned a customer for life.

Darrell Hails  1999 Craftsman 5 H.P., 22 inch Dual Stage Snow Blower, Model C950-52105-110/31/2013
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.

J. Dwight  1993 Mustang Motor in a in a 1993 Miata10/05/2013
My car has a 1993 mustang motor and 5 speed transmission in a 1993 miata. I put both the engine additive and the gas treatment in the car at nearly the same time. The car definitely runs more smoothly. Throttle response is much improved. Oil pressure is up 5 lbs. I am very pleased. I am planning another dyno tuning in the next few months. I expect a 6 to 10 hp increase (280 rwhp now) and an equal increase torque. -- J. Dwight via Amazon (Verified Purchase)
