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.

Positive reviews describe relief — someone arrived sooner than expected and treated an embarrassing error as routine, because for us it is. Negative reviews describe sticker shock. So the sticker is here: £89 to £199 call-out, £199 to £1,999 drain, and you hear your own figure on the phone, with time to decide, before anyone drives out. ## Questions we get asked **Do you work at night?** Yes, around the clock, every day. A large share of misfuels happen after dark, so the rota reflects that. **Will it have done damage?** If the engine was never started, damage is unlikely. If it ran, the risk rises with the distance driven — which is exactly why we ask. **What about a van or a hire car?** Same job. With a hire car, ring the hire company too — some policies cover a misfuel drain and it is worth knowing before you pay. **What if I have already driven it?** Still call. Most vehicles driven a short distance are recoverable. Tell us how far you got, because it changes the kit we bring. ## Who you are dealing with Wrong Fuel Carlisle is a service by Forecourt Assistance.
