I had to shorten the fill tube to clear the James cowl with my Superior -360 engine. I need to reposition the dipstick ( with the tail down of course).
I have concluded that the oil measured in the sump is the quantity available to maintain supply at the pump intake, and minimums are suggested by the manufacturers.
I have observed that filters are check valved and do not drain back to sump nor does the oil cooler. So why not put 4 quarts in the sump, or 6 and set the dipstick mark that corresponds ? You want to know how much is available to the pump no matter where the rest of the oil in the system resides after start-up. Yes/No ?
