Crankcase Type / Weight

Stupid question, yes... spec, according to Autozone, is 20W50. What should I be running in a rebuilt n/a with about 50,000 on it? Turns out the previous owner threw 10W30 full syn. in there, so I'm stuck with full syn

Factory is 10-40w, but 20-50w is fine for summer when its hot alot. I always use 20-50w in everything with over 100k on the bottom end. 20-50w will help slow down oil consumption of leaks or smoking.

What's the reccommended minimum temp. for 20W50? It's not going to get below 0 degrees F, if below 15F at all this year here in Dallas.

All right, Joel was saying it's 10W40, supra_1 says it's 10W30... which is the accurate spec?
