oil temp/pressure questions
hey i was wondering if i could get some oil basics from you guys. i have a few questions:
What makes oil temp rise?
Is performance affected when it rises?
what is oil pressure?
what makes it rise/ drop?
what pressues are too high/ too low?

These are all kinda vague theoretical questions...
