Oil question

So far there's 5-30, 10-30, 10-40, type f, and more.
I'm not home right now so don't remember brand/ weight but there's some gallon cans of some weight oil among the pile. I got about 20% of the haul in the bed of my truck, gotta take off work early one day this week when the other building is open and they can get the forklift to load the rest. All in oil cans that were common before they went to plastic bottles so probably decent levels of Zinc in it
