Are the flash/fire points directly related to how well/easy an oil will burn in the combustion chamber? This stems from the argument that rotary engines shouldn't use synthetic oil because they don't burn as well, and since rotaries actually rely on the oil in the chamber to lubricate the seals conventional oil is recommended. ![[I dont know]](/forums/graemlins/dunno.gif)
