I just purchased a 2002 Toyota Tundra SR-5, has 69,000 miles and is an automatic. I noticed the oil pressure moves up and down with the engine RPMs. The range for the gauge shows the pressure goes from 1/4 to 1/2 of the gauge face(there are no numbers on the gauge face). I've not had a vehicle that shows oil pressure going up and down with the engine speed.The oil on the dip stick looks good and clean.
