What percentage of gasoline is crude oil?

Oil is the main ingredient, I know, but how much exactly is oil as opposed to additives?

    Gasoline is mostly a cut from Crude oil. There are very few additives in it esp. compared to Motor Oil which is about 30% additives. I would expect that the additive portion is only a few percentage points. You might want to explore the link below.
