    It's 13, 14, or 15 mm

    Preferably a long box end wrench, hung straight down and whapped with the palm of your hand.

    You'll get a half cup of oil out of the filter adapter - have the drain pan under it. Pre-fill the new filter. Very snug hand-tight. Exactly 7.5 quarts including filter. Dipstick will show here - <=== ADD XXXXXXXXXX = = after checkout/draindown.
