I’ve never trusted aftermarket pan volumes. If you are using the factory dipstick and tube, it’s not an issue, but with aftermarket or locking dipsticks, it’s a guess at best. I set a factory oil pan and the aftermarket pan between milk crates. I put 4 qts. in the stock pan, then filled the aftermarket one to the same height from the pan rail. This 6 qt pan took just over 4-1/2 qts. to get to the same level, so not a 6 qt. pan, it would have been overfilled. Too much oil can cause aeration. Some drag racers will run a qt. under for a reason.
