I got some free bottles of the prestone octane additive and cleaner (orange bottle) and I use it between about every 3 full tanks. I can tell a difference in the way the trooper accelerates (for the better) and it just seems to run a bit smoother, which is good having almost 185k on it. Just my 2 cents.... <img src="/forums/images/graemlins/kewl.gif" alt="" />
