« on: December 08, 2010, 02:10:02 PM »so ive had my boat for about 6 or 7 months and i have changed my oil once and its time to do it again. The guy who had it before me used 20/50,its a 454 and i have a 6qt pan is that a good weight to run in big block?
with the way boats run, i'd change out the pan. i now use vr1 20w50. a few years ago, i didnt change the oil all season and paid for it at the end by having a rebuild the motor.
