Through the transition from leaded to unleaded gasoline, most gasoline stations supplied common leaded gasoline, common unleaded gasoline, and premium unleaded gasoline.

As soon as gasoline stations stopped providing poisonous leaded gasoline on the pumps, the pumps nonetheless had an additional button, so corporations began mixing premium and common unleaded gasoline to supply a mid-grade.
