I was wondering what people are running for oil pressure along with what kind of oil and miles? I have 97 trans am with 50k that is running 20 psi at start up and 40 psi when warm. I am running 10w 30 regular oil(non synthetic). What holds better pressure synthetic or non-synthetic oil? Let me know what you guys are running.

 

Oil pressure threads are many. A search should find you lots of input.
