Crude oil is a mixture of lots of different organic chemicals, there is alkanes (methane, ethane, propane ... octane ... C18H38) and alkalies, alcohols and lots of different hydrocarbons.
mixture
i would think crude oil is the answer to this question.
gasoline is from crude oil so it's not a pure substance
The same way you convert any density to specific gravity. Just divide the density of the substance (crude oil in this case) by the density of the reference substance (usually water, for liquids).

Refined Crude Oil
Crude Oil is typically a heterogeneous mixture.
Crude oil is a complex mixture of hydrocarbons, as well as small amounts of sulfur, nitrogen, and other elements. Therefore, it is considered a mixture rather than a pure substance.
Petro is a refined substance made from crude oil.
Fractional distillation is used to separate substances from crude oil based on their boiling points. Crude oil is heated, and its components vaporize at different temperatures. As the vapors rise through a fractionating column, they condense at different levels to be collected as different products such as gasoline, kerosene, and diesel.
Crude oil is a complex mixture of hydrocarbons that are formed from the remains of ancient marine organisms being buried and subjected to high temperatures and pressures over millions of years.
Crude oil is typically a thick, viscous liquid that varies in density and viscosity depending on its composition. It can range from a thin consistency similar to gasoline to a thick, tar-like substance.
