whats considered hot for oil temps

SouthArk370Z

While I don't consider those tests to be authoritative in any way, I think they do indicate that, in the real world, there's just not that much difference between high-quality lubes from a DD POV. Some test better on one factor but not so well for another. Your filter will probably make more difference than which high-quality oil you use.


FWIW, high-90s yesterday and I took a back road home. About 20 miles of S AR county road. Some spirited driving* but oil temp never got above 235. Temp back down to ~220 shortly after I turned cruise-control on. Back up to about 225-230 when I hit traffic. Stock '09 (no cooler). If I did that on a regular basis or for extended periods, I would have bought a cooler but it really doesn't seem to need one for the way I drive.

* Not that hard since IAT was over 100 - mine reads 6-7 high - and ECU was limiting things, but I'm selling the car this week and wanted to have some fun so I wasn't babying it.
