wow...lot of good info, but we might want to narrow down exactly what Lucas Oil product is in question ?? I have run the Lucas Fuel additive / Cleaner and have had great results. I have not used any "OIL" additives as I run full snyth in all of my cars and do not want to chance voiding a warranty. I know I am getting butt raped by the dealer, but for the extra $$ it costs it least if anything does go wrong, I have a much larger target to shoot for. If the BMW or GM tech screws something up, it's on them...not on me to go and track down "Quick Lube'
