Agreed. A few dollars is nothing, but when you can pick up really good deals, the drama of selecting an oil off the shelf soon goes away. After building a cheap stash, it becomes more like, "which oil to use first" instead of which to buy.
It's a shame Valvoline can't keep 5w-40 on the shelves, or even MaxLife synthetic. I believe the specs drive up the price, taking out of jug pricing. Mobil has it right with their spec oils and the High Mileage oils w/o spec. Maybe if Ashland had MaxLife synthetic in jugs w/o specs...
They do have 0w-20 at retail around here though.
