A few years back, Esso ( imperial oil ) produced all the lubricants for Canadian tire. Esso still produces a line of gasoline synthetic oils, in the viscousities 5w30, 10w30 and 5w50. They are PAO based lubricants like they were before. They haven't moved to group III.quote:

Does anyone there that runs 5w50 do oil analysis on it?
Up here the only 5w50s I know of are Syntec and Canadian Tire synthetic, but both of them are group 3 oils.
