I saw some pennzoil yellow bottle 20w20 in an Ace hardware yesterday. It says “for stop and go driving” on the front. I’ve never seen this or heard of it before. The quarts were pretty dusty. Is this old product or what? I googled it and didn’t come up with anything.
Pennzoil 20w20?

Are you sure the bottle didn't say 20W-50?
SAE 20 grade = water
20w20 = wet water
20w20 = wet water
Likely an HT/HS of around 2.9, so not too far off from a 30-grade.
When I first started pumping gas about a hundred years ago we sold 20w-20 in cans, Texaco brand. It was a popular oil in Colorado
From what I saw in a bit of searching it was around at least until the early 80s.
I think it was a SAE 20 monograde oil that also passed the 20W winter starting test (whatever it was back then). Which not all SAE 20 would have passed, depending on the quality of the base oil.
Remember “W” stands for winter (not weight).

The label with the black stripes shown in the picture was introduced around 1995. Bottles, cases, banners, trucks and race cars had that yellow and black scheme for a few years. The 20W-20 was discontinued around the mid '00s, I think. It had been a pretty dead product for a while by then.
had a customer back in the eighties who ran Pennzoil and Quaker State HD 20w-20 in a 78 Chevy work van with a 72 400 small block. Worked quite well.Similar threads
