alright, so this guy i work with who ive known for years and that definetly knows a lot about cars and engines. well sometimes i think he just goes by what other people say. he was trying to tell me that M1 is the best sythetic oil out there. his reasoning for this is that he was at a nascar race in the pits and watched every team pour M1 into the motors before the race. he also says he knows a guy who races legend cars that run air cooled motorcycle engines or something like that and they say that anything but M1 burns off and leaves sludge in the motor after a couple races or whatever. well i tried to tell him that there are better oils out there than M1, but that M1 is definetly a good oil. he totally disagreed with me and said that i didnt know what i was talking about. someone please give me some info to throw in his face because i know there has to be oils out there that are superior to M1. thanks in advance
