Petrol and diesel mix | Wrong Fuel Sunderland- # Petrol and diesel mix Petrol and diesel mix? The most common misfuel by a wide margin. Do not start the engine — it is drained, flushed and primed on site. Call 01293 248666 — a mobile technician comes to the vehicle anywhere across SR1 to SR6, DH4 and DH5. Call-out £89 to £199, drain £199 to £1,999. ## What "local" actually means here It means the number is answered by the people who send technicians to Sunderland, and that coverage of SR1 to SR6, DH4 and DH5 is a dispatch area rather than a marketing claim. It does not mean a building — Wrong Fuel Sunderland has no premises and never has. Call 01293 248666 and the equipment comes to you. **Search**: petrol and diesel mix **What it is**: Petrol in diesel **Where we cover**: SR1 to SR6, DH4 and DH5 **Cost**: Call-out £89 to £199, drain £199 to £1,999, quoted in full before we travel **Time on site**: About an hour **Hours**: 24 hours, every day **Phone**: 01293 248666 ## Petrol and diesel mix: what to do The most common misfuel, and the one with the most to lose by starting the engine. ## Three questions that tell us most of the story Did the engine start? How far did it run? Which fuel went in? The first two describe how far contamination has travelled along tank, lift pump, filter, high-pressure pump and injectors. The third describes how it behaves along the way: petrol thins the lubrication a diesel pump needs, while diesel in a petrol engine fouls plugs and injectors instead. ## 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. Those four things determine the price, and you hear it before we travel. - Drain, flush, refill, prime Carried out where the vehicle stands, anywhere across SR1 to SR6, DH4 and DH5. - Back on the road About an hour for a standard job. The waste fuel is removed under a transfer note that discharges your duty of care. ## The full page for this - Petrol in diesel in Sunderland ## Related searches - Petrol in diesel car - Petrol in a diesel car - What happens if you put petrol in a diesel car - Put petrol in diesel car - Petrol in diesel engine - Putting petrol in a diesel car - Petrol in diesel - Petrol in a diesel engine ## What customers say 4.8 out of 5 from 2,190 Trustpilot reviews.

The most common criticism is price, so here it is plainly rather than buried: the call-out is £89 to £199 and the drain £199 to £1,999, and the full figure is given on the phone before anyone travels. ## Questions we get asked **Is this a garage?** No. Wrong Fuel Sunderland is mobile. A technician travels to the vehicle wherever it is standing. **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. **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. **Can you come to a supermarket forecourt?** Yes, and it is where a good proportion of jobs happen. Tell the cashier a drainer is on the way; they are used to it. ## Who you are dealing with Wrong Fuel Sunderland is a service by Forecourt Assistance.
