Does petrol just appear at the station ready for use? Less than half of crude oil makes it into your car. It travels thousands of miles from the well to refinery, where a chunk of it is burnt to power fractional distillation and separate out Sulphur, impurities, bitumen, kerosene and other stuff that would ruin your car. It's burnt to power catalytic cracking, to convert heavier compounds into something combustion engines can burn. Obviously t is consumed in engines of trucks and ships to deliver it to a petrol station.
