Title: I have been using it since 1987
Review: My dad had an 82 caprice diesel 5.7 liter. My dad must have known about it a while but I found it on the shelf in our garage in 1987, my dad told me he would put about 8 ounces in a tankful of diesel every few tankfuls. We put about 240K miles on the caprice. Most people we knew with GM diesels during that era did not get that kind of miles on their motors. Fast forward to today, I use this in all my gasoline motors. Snow blower, generator, lawnmower, power washer and even the two cycle leaf blower. It also keeps the gasoline stable. When hurricane Sandy hit us and we ran out of gas, I siphoned gas out of the small engines in our garage rather than wait in line for four hours. Kept us going for a few more days. I use it more frequently in winter than I do in the summer because it definitely helps cold starts.
