Installed with capacity of Mobil One 5w30 in my 244k mile Sierra and was rewarded with engine tap that went away after a few miles and noticeably lower oil pressure(about 25-30 at 15-1600 rpm. Normal readings were about 40-50 at 15-1600. I began to think definte trade in time. Decided to drop in and pick up the stand by Delco filter today and viola, instantly quieter engine and back to the normal pressures.
Never in over 40 years of changing my own oil have I ever seen a defective filter. Anyone else and with the new can't be beat Fram ?
