just throwing this out there...be sure the mobil one "jug" is actually 5 quarts. I just bought some (I always get mine from WalMart) and all the "jugs" on the shelf of the various weights (10w, 15w, 5w, etc) were now 4 quarts...so I had to buy a lone quart as well.


This sucks...'cause I really liked getting all 5 quarts in a one shot deal. I noticed other brands (Valvoline, etc.) still had 5 quart jugs available.
