Ah shucks. The oil isn't even begining to thin out yet.
Particularly if you are using Mobil 1.
I used to pilot a 300SL MB (Remember the flying doors?)
The oil temp gauge went from 110 to 250 deg F with a very small red zone AFTER
the 250 mark. And this took into consideration that oils available when
was designed were very much poorer that what you are running. Don't fret,
there and REALLY mash on it. When Mobil 1 first came out about 20 years ago,
it was ONLY available in 5W 20. Porsche drivers used it regularly, because
no oil pressure gauges to scare the absolute hell out of them. But they didn't
break. I would run 3 qts of 20/40 to 1 quart 10-30. Works great in my 200
As the seasons change, and as required, I add 1 quart of the thicker or
to keep the same oil pressure at max temp for the season.
