The Trop Artic website shows 5w20 as one of the listed semi-synthetic varieties, but I've never seen anything but the 5w30 and 10w30 in the semi-synthetic stuff.
I've seen 10w40 in the old API SL rated dino juice, but who wants that?
3)end cap about 2 mo ago. all types incuding 5/20 5/30 synblend and dino. it is all long gone with a few 10/30 in a section. I think it was a one time thing as they have not restocked or replenished this brand the same lonely bottles is there everyweek.
