The tank is just where it starts. Damage happens at the high-pressure pump, which relies on the fuel itself for lubrication and has very tight tolerances, and then at the injectors downstream of it. Reaching either requires the engine to have run, which is why a car coasted to a halt on the forecourt is almost always a call-out and nothing more. ## 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 TS1 and TS3 to TS8. - 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 - Small amount of petrol in diesel in Middlesbrough ## Related searches - I put 5 litres of petrol in my diesel car - 20 litres of petrol in diesel car - Small amount of petrol in diesel car - Small amount of diesel in petrol car - 10 litres of petrol in diesel car - Small amount of petrol in diesel engine - 15 litres of petrol in diesel car - 5 litres of diesel in a petrol car ## Independent reviews, unedited Trustpilot: 4.8 out of 5, 2,190 reviews.

The full price for your vehicle is confirmed on the phone before a technician sets off, so there is no surprise when we arrive. **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. **Do you cover all of TS1 and TS3 to TS8?** Yes, from one rota — so being at one edge of the area rather than the other changes the arrival window, not the price. **How long will I be waiting?** Arrival depends where you are across TS1 and TS3 to TS8 and what is already running.
