I've been using the Motorcraft oil in the five gallon jugs for the last several oil changes now and I think it is a fine oil.
But I screwed up the first time and put in 3 and a half jugs thinking they were four quart jugs and overfilled the crankcase with 17 and a half quarts, versus the usual 14 quarts I get from 3 and a half four quart jugs of Delo.
It took me a while to get used to the five quart jugs.
(Just don't ask Gooch about antifreeze and we'll get along just fine)
