You can now buy Castrol Syntec 5W40 at Canadian Tire stores. I just puchased a litre for $9 Canadian.

Under the US definition of "synthetic", oils made of group III, IV, or V base stocks are "synthetic". Under some other definitions, only group IV or V base stock oils are "synthetic". Group III base stocks are highly processed mineral oils with viscosity index and other properties very close to those of group IV polyalphaolefins, which are built up from smaller hydrocarbons from natural gas.Quote:>>yep, its fully synthetic syntec 5W40 for VW engines.<<
I may be wrong, but I thought I read somewhere that the "synthetic" Syntec is NOT fully synthetic, although the advertising says it is... What's the rating on it? CF4, CG4 or higher?
In any case, I use the Shell Rotella T Full Synthetic (which may not be, either)...
