Here is my dilemma. The manual for the LT1 f-body shows the oil capacity as 5 quarts with the stock oil filter. The long one I run takes maybe a 1/4 quart extra at the most. But when I change my oil I need to add 5.6 quarts to get it to the full line. Should I trust the dipstick and continue doing this? Or should I run 5.25 and see where that shows on the stick, and treat that level as the actual full line? I'm worried because other LT1 f-body owners have told me they only need to run 5qts with the long filter to have it show full on the dipstick. Why the large discrepency?
