The MerCruiser 5.0 engine, including both carbureted and Electronic Fuel Injected (EFI) versions, is designed to operate on unleaded regular gasoline. It requires fuel with an octane rating of 87 or higher. This specification ensures that the engine performs efficiently without risking damage from lower octane levels, which can lead to engine knocking and reduced performance.
