Quick tests
Meaning / construction test
Are you naming the common fuel used in petrol/gasoline-powered vehicles?
If yes: Choose “petrol” for UK-oriented prose or “gasoline”/“gas” for US-oriented prose.
If no: If you mean another petroleum product or an actual gas, use the term for that substance rather than treating the words as universal equivalents.
Caveat: This is a regional vocabulary choice within the motor-fuel sense; broader uses of “gas,” “petroleum,” and related fuel terms are not automatically equivalent.
Examples
The car is almost out of petrol.
“Petrol” is the usual UK-oriented term for this motor fuel.
The car is almost out of gasoline.
“Gasoline” is the US-oriented term for the same motor-fuel sense.
The refinery produces several petroleum products.
The petrol/gasoline equivalence does not cover every petroleum product.
