Petrol and gasoline are essentially the same product. The term "petrol" is more commonly used in British English, while "gasoline" is more common in American English. Both words refer to the petroleum-based flammable liquid that is used to power internal combustion engines, such as those found in cars, motorcycles, and other vehicles.
It is possible there may be small differences in formulation that make petrol found in the UK slightly preferable.
