My local Ollie's has Wolf's Head 5w20 full synthetic for $2.99. I grabbed 8. I don't have any car that specs that weight but I can mix it with some 10w30 synthetic and that'll work for my cars.
I saw this oil several years back but it's not really anywhere I usually buy oil. I believe we got a new Ollies in the town over from me though. I need to get in there to check it out.
Good ole wolf's head used to get this in 5w-30 conventional in the early 2000s. the newer stuff is amalie same as stp and fram motor oil supplier and sure there are several other private labels.
It used to be common at independent part stores and NAPA in MD, but I haven't since it in 20 years.
Like we used to see Dryden Oil Company Drydene that originated in Baltimore. It was everywhere in MD, but not any more.
WH and Valvoline were the base-line at local/independent part stores here in VA. Early '90's I worked at a heavy truck place; Just about every petro product we sold was WH. Delivery came 2x week (Small truck from PA I think) and the sales rep was in all the time. My '66 Mustang ran on it for years.
