That's pretty hot. I dont have a oil temp guage in my boxster, but
In my Audi i typically run about 170-190 degF; on the track i have hit 230-240F. That was a hot day, running dfoot to floor pretty much all the time (pocono).

100 degC is simply the typical temp for hot viscosity measurements. Note there is no magic number; there's a fairly smoo9th viscosity curve vs temperature.

Now, go back and read again. I specifically said it si NOT BETTER. I specifically said it is APPLICATION DEPENDENT. 20w40 would perform better under hgih temps and loads and worse when cold. So for typical use, it would be in fact worse.

I can't be more clear.
