A1Difficulty 2/5

A petrol-engined motorcycle with a catalytic converter needs refuelling. What fuel must it use, complying with the manufacturer’s specifications?

Correct answer

Unleaded petrol

Unleaded petrol with the octane rating and composition permitted by the manufacturer. Lead can damage the catalytic converter, so meeting the octane rating alone does not make leaded petrol suitable. Do not add a lead substitute on your own initiative either. Check the manual for ethanol blends and other additives permitted for your model.
