1a. Don't worry, I won't laugh. I truly want to know if somebody has tried Z MAX in thier truck yet? I know there is a lot of talk about,"Snake oils," but I believe that if a product can truly reduce friction in the engine, it would be beneficial. It is not inpractical to think in this day of modern science, that a high tech lubrication company could develope a additive to reduce friction. Z max offers a 100%, 10% increase in mileage or your money back! I'm probably going to try some. If anybody has tried some, let me know your report. Thanx, Taxman
