The Greek roots

πέτρα

+
ἔλαιον
élaion
olive oil

Literally: rock oil

The story of the word

British drivers fill up with a shortened medieval Latin word for the crude seepage found in rock. Petrol was pushed into general use in the 1890s by London refiners selling motor spirit, while American English kept gasoline. The Greek half is only the first syllable pair: oleum is Latin, though Latin itself took it from Greek élaion.
