What gas does a v6 engine take?

A V6 engine typically takes gasoline as its fuel. Gasoline or petrol is the most commonly used fuel in spark-ignition internal combustion engines. It is a mixture of hydrocarbons, primarily alkanes, that are refined from crude oil. The octane rating of gasoline indicates its resistance to knocking or spontaneous ignition, which can cause damage to the engine. Depending on the specific engine design and manufacturer's recommendations, a V6 engine may require a certain grade of gasoline with a specific octane rating. Some modern V6 engines may also be designed to run on alternative fuels such as biofuels or natural gas.
