Sense: noun/1
Gasolene (along with its standard spelling gasoline) and petrol refer to the same liquid fuel for internal-combustion engines, but they belong to different regional varieties. Gasoline (or gasolene) is the dominant term in North America, while petrol is the standard word in British English and most Commonwealth countries. In everyday North American conversation, the short form 'gas' is far more common than gasoline ('I need gas' vs 'I need gasoline'). 'Petrol' is not shortened in the same way, though Australians and Brits may say 'fill her up with petrol' or 'a litre of petrol'. A speaker who uses 'gasolene' instead of 'gasoline' may sound old-fashioned or be using a British variant spelling — modern dictionaries label it chiefly as a variant of gasoline.

Etymology
Gasolene was originally coined in the 1860s as a trade name for a light petroleum distillate, formed from gas (referring to gasoline's vapour) + the chemical suffix -ol (from Latin oleum 'oil') + -ine/-ene. The spelling gasolene emerged alongside gasoline; the -ene ending follows the pattern of other hydrocarbon names such as benzene and kerosene. Over time, gasoline became the dominant form in American English, while gasolene survives as a minor variant, more common in older British texts.
