Oil Pressure
Posted: September 12th, 2006, 4:16 am
i have an autometer oil pressure guage installed and was wondering if anyone could give me an explantaion of the vary oil pressures i have experienced. During startup of pressure is around 60psi (high obviously), then after idling for a while it drops to 20psi which seems fairly normal. When i have the car serviced with new oil it runs at 65-75psi on startup, then 25-30psi on idle after warming. It receives the correct amount of oil. After a few hundred kms it drops again. Why do i have this variance?? Am i buring oil slowly? it doesn't seem to smoke at all, and i have no oil leaks under the car...
