My experience in getting Mobil 1 in bulk added up to either buy cases taking advantage of rebates, etc., or buy the 55 gallon drum! I heard rumors of 5 liter jugs, 15 liter jugs, but Mobil and the distributors I called said it wasn't available in anything but the quart containers or 55 gallon drums. Bummer.... David BTW, there is a 3 dollar rebate running now, got the forms at KMart.
