Kind of funny that a car designed for sustained >160 MPH driving ends up having adequate cooling; is it not?

Sump temperatures are not what the 302F temperature is based on in the HTHS test. Local oil temperatures in bearings that are higher than sump temperatures is what it's primarily based on. The high shear rate used in the test is equally important due to temporary shear thinning that occurs with multi-grade oils.


I agree with the above data.
