It is the other way round. Wrong fuel sitting in a tank is inert — it is a drain. Turn the key and it travels: lift pump, filter, high-pressure pump, injectors, and every stage it reaches adds a component to the bill. Five litres burned is worse than fifty litres left alone. ## 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 TS1 and TS3 to TS8. - 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 - Petrol in diesel in Middlesbrough ## 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 drivers tell other drivers 4.8 stars, 2,190 Trustpilot reviews. The advice drivers pass on is simple: do not start the engine, ring, and expect someone level-headed who knows exactly what to do. The warning they pass on is that it is not cheap. Fair enough — the call-out runs £89 to £199, the drain £199 to £1,999, and both are stated before a van leaves, so nobody is surprised at the roadside. ## Questions we get asked **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. **Can I just top it up with the right fuel?** No. Dilution does not fix contamination, and driving to a filling station to try it is the mile that turns a drain into a repair. **What happens to the old fuel?** It leaves with us as controlled waste under a waste transfer note. It is not tipped, and it is not resold to you. **Is this a garage?** No. Wrong Fuel Middlesbrough is mobile. A technician travels to the vehicle wherever it is standing. ## Who you are dealing with Wrong Fuel Middlesbrough is a service by Forecourt Assistance.
