That there I find interesting...I got this from a well known racer..There are two Moroso pans that are advertised as 7 quarts...One is actually 6!! Why they sell it as a 7 quart pan is beyond me. Also why would Barton tell you to only run 6 quarts? When you changed oil did you put a 1/2 quart into the filter then top it off? Did the dipstick read at the full mark? What pickup did it have on it??
