Funny the TP oil filter is mentioned. At church last, we were talking oil and filters. One older guy than me made the comment. A freind had used TP filters and never changed the oil, only the TP. He said, the guy got over 150k on a 6L chevy motor and never had any trouble. Still running when he traded it in.
All I said was, Hmph.....LOL......Maybe the motor was rateling and the guy was deaf....LOL
