Back in June I got a 1993 Ford Ranger with 170,000 miles with the 3.0L Vulcan V6 engine. It currently has PYB 5w-30 in it since I bought it and it leaks roughly 3/4qt of oil every 1,000 miles. Its an old truck so Im not going to go crazy about fixing the leaks so I wanted to hear your guys opinion on the best HM oil to use with the best performing seal swelling additives. Im very very tempted to use Super Tech HM going forward for the value $14.63 price tag.
