Cerma Gun Lube. I followed the instructions as directed. I shot a 30 round magazine as fast as I could pull the trigger out of my AR-15. After shooting the rounds I accidentally brushed the barrel of my gun with my forearm and instinctively pulled it away so not to get burned. ...

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 ...

Jeep Grand Cherokee

I purchased a 1996 Jeep Grand Cherokee with 196,000 miles on it. The transmission was beginning to act up after a couple of months driving the vehicle. What was happening was when the Jeep was shifting into over drive at 50 miles an hour it was not as smooth as it should be. After ...

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 ...

Yanmar Tractor

I was a skeptic, but when I added the Cerma Engine Oil Treatment to my Yanmar, the change was amazing! Within 20 minutes the engine smoothed out, became much quieter, and is clearly running much better. I can pull an extra 300-400 rpm – that means more horsepower out the shaft – without ...
