My oil change regimen involves pulling the plug and filter and letting it drain overnight. I use an oversize Mobil 1 # 110 oil filter. I pour some oil into the filter and swish it around to soak into the filter element and then fill the filter about 1/2 way before carefully screwing it back against the flange.
I then add 5 quarts plus another 1/4 from the bottle that I prefilled the filter with. After start up and checking the oil level later that day, my oil level on the dipstick always is exactly on the the top dot. So I can tell you even if you use a slightly oversize filter, 5 1/2 qts is the max that you will ever need with a stock engine, pan and no add on cooler.
