Filler neck, tank, a lift pump drawing from the bottom, a filter catching debris, then the high-pressure pump squeezing fuel to enormous pressure for the injectors. Wrong fuel is harmless at the start of that route and expensive at the end of it. Only running the engine moves it along. ## Step by step Ignition off and stay off No starting, no accessory position, no quick test. Contamination still sitting in the tank is the best case, and it lasts exactly until the engine turns over. - Keep the vehicle still Even rolling it a few metres can move fuel toward the pickup. If the spot is safe, the spot is right. - Look after people first Hazard lights on. Passengers out and clear if there is passing traffic. On a forecourt, let the staff know what has happened. - Phone 01293 248666 Give the vehicle, the fuel that went in, an estimate of the amount, and whether it ran. The price comes back on the same call. - Extraction on the spot The tank is drained, the lines flushed, clean fuel added and the system primed — anywhere across SR1 to SR6, DH4 and DH5. - Paperwork and the waste An invoice for you; the contaminated fuel leaves with us as controlled waste under a transfer note. ## The full page for this - Unleaded in diesel in Sunderland ## Related searches - Unleaded in diesel car - Unleaded in a diesel car - Unleaded in diesel - What happens if you put unleaded in a diesel car - Put unleaded in diesel car - Unleaded petrol in diesel car - Unleaded in diesel engine - Putting unleaded in a diesel car ## Reviews, including the bad ones 4.8 out of 5 across 2,190 Trustpilot reviews. Praise clusters on two things — speed of arrival, and technicians who do not make a driver feel stupid about a mistake anyone can make. The complaint that comes up most is cost. It is a fair thing to raise: call-out £89 to £199, drain £199 to £1,999, the full price confirmed before a technician sets off, and if the job turns out to be different you are told before further work, not after. ## Questions we get asked **Is this a garage?** No. Wrong Fuel Sunderland is mobile. A technician travels to the vehicle wherever it is standing. **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. **Do I need to stay with the vehicle?** Usually yes, so we can hand it back to you running. If you cannot stay, say so on the call and we will work out how to do it. **How long will I be waiting?** Arrival depends where you are across SR1 to SR6, DH4 and DH5 and what is already running. You get a realistic window on the call rather than an optimistic one. ## Who you are dealing with Wrong Fuel Sunderland is a service by Forecourt Assistance.
