Not only is the most popular Ford oil filter in short supply, the FL500, but so is the PF63 AC Delco, which for all purposes is the exact same filter. The NU2Z filter is a replacement for the 500, so there is an out but the new filter is longer. Also, good luck finding ULV transmission fluid. You won't find any.
I've been to a handful of places the last week or so. Each of these businesses were aware of the topic, but had not received any guidance to operate different. Sites that work in bulk barrels, possibly refined at overseas locations, I believe are seeing the worst of it.
I haven't found bottled oil in short supply, but I have noticed some weights or types might not be available. Instead of seven weights or versions of Pennzoil, there are five. Shelves do get cleaned out on the weekend, almost any location.
While the filter brands associated with the bankruptcy are out, I haven't seen shortages of others. If you do visit a store and a particular brand or size is not there, ask about it. Businesses in my area keep most in the back, because of thieve'n. People swap one low-end filter for a better one, keeping it in the same, low-end box. Or steal it outright.
