A two-stroke petrol motorcycle uses premix lubrication without an automatic oil dispenser. What must go in its fuel tank according to the manufacturer?

Correct answer

Petrol mixed with two-stroke oil at the specified ratio.

Petrol mixed with suitable two-stroke oil at the ratio specified for that engine. Do not invent a universal ratio or use diesel. The oil provides lubrication and does not turn petrol into diesel. With separate lubrication or automatic oil metering, the manufacturer may require petrol in the fuel tank and oil in another: do not add premix on your own initiative. The question excludes that system.
