0W-30 Oil - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Just wondering if any club members have run heavier weight oil in their cars. I do a lot of hi-way driving (80 mph @ 3500 rpm)...live in the midwest, winters can be somewhat brutal. 0w-30 just seems like it would be a better choice?

Yeah you should run heavier oil for a colder climate.

Highway driving is the easiest on an engine, even if you are going 80. In most temps, say from freezing and above, a 0W30 will usually be thicker than the 0W20. But when it gets to freezing and well below, the cold cranking viscosity on both oils is tested at -35C.

PQIA Cold Crank Viscosity

Of course at operating temp, the 0W-30 will be thicker than the 0W-20, but possibly not by very much. You have thick xW-20's and thin xW-30's and the operational viscosity may or may not be that different. The second number on the bottle represents a viscosity range.

That said, 0W-20's do very well in these cars if you are stock and are not on a race track.
