1998 Chevrolet K1500 Silverado 8 Cyl 5.70L
When i slow down or come to a stop my oil pressure drops to about the 20 on my gauge is the motor bad?
It takes about 10 min of running and then the oil pressure gets low. the truck has roughly 185,000 mi on it. it happens all the time.
I would say worn. Use high mileage oil with a higher viscosity
