Pts.,,power train seal,meaning you have a leak in a main bearing seal,but i would not trust a walmart oil changer to diagnose this,it may just be a gasket leak,go have the oil cleaned from under truck and have it checked by a pro.


After giving you such helpful advice, I hope the service guy remembered you were there for an oil change and completed it! I would quickly check my oil level if I were you and then run to a reputable shop.
