Just seems harder to find lately. My older, local Walmart hardly ever has any lately. The labelled spot on the shelf is either empty ot just one or two qts. I thought perhaps demand was exceeding supply and they couldn't keep it on the shelves, but a brand new Walmart Supercenter just opened up nearby, and there is no M1 0W40, not even a spot for it.
In fact, there seemed to be much less shelf space assigned to M1 and more to the Castrol products.
Any one else noticing this?
