"1989 cru-454 w/ alum oil pan.
"1989 cru-454 w/ alum oil pan. Dipstick reads full, great pressure, never have to add oil. At the end of season, use a pump down the dipstick to remove oil. I can only get a little over 1 gal, (4+ quarts). I think I remember putting in 7 or 8. The engines are tipped toward the drain, (angled) and the dipstick tube goes to the bottom of the pan. Am I missing something? Am I leaving spent oil in the pan by doing it this way? I know there will be some in the filter but not that much. Confused, please help!!"
