I think 20w50 is what you'd want for track use but daily driving I'd think 5w20 would be fine.

It would need to be a pretty hot environment for anyone to need 20w50 in one of these engines. Places like the Sahara desert and the face of the Sun come to mind...

Actually, I'm pretty sure back in my CarQuest days a guy running dirt track bought 20w50 Racing oil.
Excellent comparison. :nonono:

Because you are not tracking your car and 5W-50 causes excessive oil pressure run either 5W-20 or 5W-30. You'll never know the difference.
