oil pressure
what should the oil pressure be on a stock motor 90 gt? i've heard the rule is 10psi per 1000 rpm's. w/ my autometer electric oil pressure gauge taking readings from the stock location next to the oil filter. i run 10w-30
when cold:
idle 750rpm = 45-50psi
2000 rpm's = 55-60psi
oil pressure will get lower as car warms up....
when at operating temp: (190-195F)
idle 750rpm = 20-25psi
2000 rpm = 45-50psi
20-25psi seems a little low to me, but it never dips under 20psi. should i start using 10w-40 when winter is over?
