I was at Wal Mart this morning and had five quarts in my hands priced at $4.47 each. I stumbled across a display with 5 Quarts in one jug for $17.97. I got a few of the 5 quart jugs. It takes exactly 5 quarts for my daughters pick up. Very convenient.
BTW. Remember that Mobil One and Mobil DELVAC One are two different products. The Mobil DELVAC One would be much more desirable for diesel engine use.
Have a great day,
