Whoops I just buy the 5 quart jug and fill it up. Guess I'm going to have to buy the BSR Kit so I can actually use the 5th quart. lol. Also out of curiosity I started doing this because I heard of oil starvation in auto-x is it true that if I overfill it by one quart it'll have less chances of doing this? And why does it post without filter aren't you supposed to change your filter with every oil change?
