I have a few old cans including Veedol, Kendal, Quaker State, Valvoline, and Cam2, as well as a few ATF and a lawn mower oil all in the old round cans. I have a couple boxes of empty modern bottles in the attic (even garbage picked at the auto part store a few times to get a good variety). I may save a bottle of Maxlife SAE30 because I believe it is not discontinued.
