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.

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)

At first I thought this was another slick50 type product but after checking out the website and finding no bad reviews I said what the heck let me try it. I've lost money on slick50, prolong, and zmax so what's one more. I put Cerma STM-3 Engine Treatment in my 1988 Mercury Cougar XR7 5.0. I was surprised that I actually felt a difference. The engine is running smother. I have 162,000 original miles on the engine and put on 500 mile after adding Cerma. I just have to say with all my heart, Thanks Cerma! Oh my car thanks you too.

O ahhhhhhh mazing :) At first glance, i thought the price was a little crazy.but some in-the-know car guys that i know convinced me to give it a try, and i probably shouldn't have tried it on my only vehicle, but what the hell :D. my vehicle wasn't in bad shape (2004 silverado 5.3 v8) it had a slight tick at high rpm/high speed, i didn't make loud noises/vibration. i received the Cerma engine treatment very quickly ( fast shipment), eager to try. i used as instructed and im very impressed thus far with the results. improved pick-up, engine is quieter, ticking at high speed gone :D. i believe i will consider purchasing other Cerma products. please note this has been only the first day, will update if anything changes/improves. have a great day -- Stephen Reposted from http://www.amazon.com/Cerma-Gas-Ceramic-Engine-Treatment/dp/B00AZONLUC/ By stephen on May 23, 2013:

I must admit that I tend to view products with skepticism however the proof was in the data. I saw a legitimate 200 fps gain in a 16” AR-15 that would be the equivalent of having a 20” barrel, as well as a legitimate 150 fps boost in a 40 cal Sig P-229R. Now when cleaning time came around, both guns pretty much wiped clean with minimal fuss. I am looking forward to tinkering with this product and can see that it also has some potential for USPSA shooters who have to meet a minimum power floor providing extra velocity without pressure increase.

I have been using Mobil 1, Shell Helix, Castrol Edge, and now Cerma (Cerma is the best motor oil I have ever used) At first I thought it was my engines life was up, but when I tested Cerma my engine came back to life , on my second car the same thing happened. the piston rings were worn out and I had this changed, and your Cerma oil is all it will ever use.

Would recommend this to anybody who is looking to keep their engine long lasting no matter how many miles is on it. Already used on three of the four cars in our household and have noticed a smoother sound to the engine as well as increased gas mileage on each tank at least getting 50 to 60 extra miles on each full tank on the cars. -- via Amazon (Verified Purchase)

I put Cerma Trans in and have noticed the trans shifts better and the temp gauge is reading cooler.

I am amazed at this product. I put Cerma STM-3 in my 2009 subaru imprezza and went from 33 mpg hwy. to 38 hwy! the engine seems to be so smooth you can't tell it is running! So then I put it in my 04 dodge hemi sport truck and went from 15.5 to 19.5 mpg hwy! unbelievable!! this stuff is the real deal! I will be ordering more and will treat the transmissions and a/c units and see what that will bring.

We have used Cerma in a gear box which is 1 of 2 identical units. The one
we treated was initially running 60 decrees hotter than the other one. We want them to
run at no more than 180 degrees. The manufacturing company tried changing out the
gears and in essence did everything they knew to try to make it run cooler with no
success. At this time we shutdown said gear box and treated it with 8 oz. of Cerma . Now instead of running 240 degrees like before it is down to 195 degrees
something even the manufacturer couldn’t accomplish. In the near future I will be
treating at least 4 more gear boxes to reduce wear. We feel that this is cheap insurance as if even one of these gear boxes failed we would be looking at at least $250,000 damage to our equipment.
