NEVER USE A FRAM
MY 377 carries 40 lbs oil preasure at idle - PLUGED BYPASS - changed the oil and installed a FRAM OIL FILTER - oil pressure to 21 lbs at idle - reved to 3000 had 22 lbs - wow i got a problem - changed the oil filter back to a NAPA PRO SELECT and the oil pressure was right back up to 40 lbs - fram is junk and you can take that to the bank - :lol: = VIC
