Run a diesel high-pressure pump on petrol and it wears fast, shedding fine metal into the injectors behind it. None of that happens while the fuel sits in the tank. All of it starts the moment the engine turns over. ## Step by step Do not start it — that is the whole thing Everything else on this list is detail. This one line is the difference between a call-out and a pump. - Leave the vehicle where it stopped Pushing or coasting is still movement, and movement is how contaminated fuel finds the pickup. - Sort out safety Hazards, and get people out of the vehicle if you are anywhere near moving traffic. - Call 01293 248666 Answered around the clock. Tell us what went in and whether it ran; you get the full price before a technician sets off. - The job itself Extract, flush, refill, prime, run up, check. Roughly an hour on a standard vehicle. - Old fuel away, invoice done Controlled waste, transfer note, registered carrier.

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.
