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 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 - Wrong fuel in Sunderland ## Related searches - Wrong fuel in car - Wrong fuel - Wrong fuel in car near me - Put wrong fuel in car - Wrong fuel recovery - How to dispose of petrol - Mechanic near me - Fuel fix ## What customers say 4.8 out of 5 from 2,190 Trustpilot reviews. The thing reviewers mention most is technicians who stay calm and professional with someone who is having a bad day, followed by how quickly a van turns up. 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 there an out-of-hours surcharge?** The call-out is the call-out. Whatever the total is, you hear it on the phone before anyone travels. **Do you cover all of SR1 to SR6, DH4 and DH5?** Yes, from one rota — so being at one edge of the area rather than the other changes the arrival window, not the price. **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. **Do you work at night?** Yes, around the clock, every day. A large share of misfuels happen after dark, so the rota reflects that. ## Who you are dealing with Wrong Fuel Sunderland is a service by Forecourt Assistance.
