I never needed to measure, 4.25= 4qts and close the hood. No matter how many beers you drink while watching it drip, there will always be a residual amount in the pan....
Furthermore, my Taco according to the owners manual says 5.5qts, but all aftermarket oil filters are smaller than the OEM, so smaller filter + residual = 5qts right on the full line....
Close the hood, drink another beer and show your wife/girlfriend, husband/boyfriend, neighbor/mistress, whatever! some quality time........
