Question about 1995 Jeep Grand Cherokee
Oil pressure is 40+ when first started. After a few miles it slowly drops and finally goes nearly to zero. When engine is turned off for a few minutes and restarted the pressure returns to about 30 but then drops again. The oil is fresh 10/40.
Your oil pump is either weak or there is sludge i9n the oil pan. my adives is to have the oil pan dropped . chances are sludge is the culprit. as the oil get's warm the pressure should only drop slightly but pressure is generally dictated by engine rpm. pumps are gear driven so if it was a bad pump your oil pressure would start out very low at start up.
