I bet anyone stumbling on this site will be flabbergasted to find anyone has an "oil stash," LOL.
But yeah, I am stocking up on Pennzoil Ultra 5W30 while I still can. I currently have 3 5QT jugs and 1 QT jug, but I'll be getting 2 more of the former and a 6 QT case of the latter within the next few weeks. It's a few years' worth of oil changes, but it's worth it to me because it's getting harder to find and I am going to be starting my own business at the first of the year, and I won't have as much disposable income to pay premium prices for it if folks don't start stocking it. This way, I get oil changes to roughly 40,000 miles for $21 per (price for the dealership to do the work and provide the filter). That should last me 3-4 years or so.
The 6 QT case will give me some extra to top off with in addition to rounding out the extra 3/4 quart above 5 quarts for each oil change.
