I would even mind the no option part, if they would at least tell us what the consequences were. Like the zinc in the oil thing, but I don't know exactly which type of public forum they would/should use to disseminate this type of information....Perhaps large type signs on gas pumps like the ones they use to tell you gasoline is flammable, (no kidding), or the same type of label they put on cigarettes, on oil cans. (you can tell I am getting old, when was the last time they used cans for oil?) It can't really be that hard.
