Is my oil pressure Low?
1972 307 in 69 C10. See below pics. Low reading is at idle when warm. High reading is driving at normal highway speeds. I have read that hash marks on gauge are for O-15-30-45-60 psi. If that is correct then I idle at 5 or 6 psi and at about 30 on freeway. Is this low or normal for a high mileage engine?
