Distance travelled through the system does. Fuel that never left the tank comes out with a pump and a hose. Fuel that reached the high-pressure pump may have begun wearing it, and fuel that reached the injectors may have carried that wear with it. ## Step by step Key out, hands off An engine that has never run on the wrong fuel is a drain and nothing more. That is the cheapest outcome available and it is still on the table right now. - Do not move the vehicle Not into a bay, not onto the verge, not around the corner — unless it is genuinely unsafe where it is. - Hazards on, tell someone Forecourt staff are used to this and are rarely difficult about it once they know how long you will be. - Call 01293 248666 and be specific Vehicle, wrong fuel, rough quantity, engine started yes or no.
