I am a parts salesman for a living and build engines on the side. I am so impressed with your products, if you are ever able to make them better i would love to see it. we use your oil and stabilizer in demolition and circle track engines and it is amazing how much temperature and fuel dillution they can take. It sticks so well to the parts, i can pull an engine apart on a sunday and if its apart all week its still drips out on the next sunday, thats amazing. Your transmission stabilizer is amazing also. We once built a demolition derby car using an old transmission that wouldnt even pull itself onto the trailer as we went to load it for a derby many hours away. we dumped two quarts of the tranny stabilizer in and it is still running to this day. one year ago i pulled a 350 chevy tranny apart that had 26 demolition derby's on it and the first and reverse clutch pack had absolutely no friction material left on them, but this tranny still worked very well and never got hot nor were the plates welded together, it amazed me. i am yet to use a product of yours that i was not amazed by, keep up the good work thanks.
