Stop; leave the vehicle off. Emptied then rinsed, just where it sits: that is normally all an unrun diesel with petrol in it needs. Whether it stays that straightforward rests on the minutes to come more than on everything else. Here is the order of things from now, wherever you are in Gospel Oak. ## Petrol in a diesel? What to do in minute one Do the following first, in this sequence. - The keys out of the ignition. Switching your ignition on can be enough to prime the system, while priming draws petrol out of your tank towards the parts it harms. Keep it off completely. - No diesel on top. More fuel in takes away none of that petrol — it just makes you with more of the same mixture. - Make the vehicle easy to see first — hazards on — if there is traffic going past anywhere near you. - The staff will usually help you roll it away from the petrol pump. Let them, and move it by hand — never under the engine, even for a couple of yards. - The first question you will be asked is which fuel went in and roughly how much — and your receipt shows both. Keep it. Realised on the move? Get off at the next exit if you're on the M1, under 5 miles from Gospel Oak, and pull over somewhere sensible — not at the services further on. Step one comes after that. ## Has it run yet? The fork in every Gospel Oak fuel drain From this stage on, everything hinges on a single answer. If it has not once been started: - That petrol is still inside your tank and nowhere else. - Where the car sits is usually where the work is done: a drain, then a flush. - No position is better, and it's why the first step counts so much. If the engine has run, even for a moment: - Out of the tank, past the fuel filter, into your lines: that is how far that petrol has got. - On a bigger run it has got to your high-pressure pump as well as the injectors. - Lines flushed, the fuel filter sorted, occasionally more: the job expands as the mileage does. That line falls there since diesel protects the high-pressure pump and your injectors on its way through them — and petrol does not. In your tank, sitting still, petrol harms nothing. The parts that move it are wearing the moment petrol is being pumped. ## Before you call about petrol in a diesel in Gospel Oak: what we need Prepare a little, and the technician finds you rather than circling. - Your location: a postcode starting NW3 2 works best. - Wherever you have parked, the road's name helps — whether that is Estelle Road or somewhere else — and so does the name of a car park. - What a car park serves is the quickest way to find it, so say the landmark — such as the one at Londis. - The car. Make, model, plus that it is a diesel. - Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has a separate Gospel Oak page. - How much. Litres from the receipt, or how long the nozzle was in the filler. - Has it run? If so, say how far it got, and the way it was driven. - Hire or company car? Some contracts want the owner's authorisation for the work, and sorting it before our technicians get there is faster than afterwards. Phone 0333 366 0103 next. Email works too if it can wait, with the car parked at home, going nowhere. ## The wait for a Gospel Oak fuel drain, and what to do in it In the wait, the damage comes from well-intended help — which is why these matter. - Where the vehicle has stopped decides where you wait. Exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety ahead of the vehicle. - Not to roll it a couple of yards, not to check it is all right, not as a passer-by's kindness: nobody starts it. - None of it gets that petrol back out — not two-stroke oil, not injector cleaner, not anything from your boot. So no additives. - Draining it yourself is out: a can of siphoned petrol on a verge is a danger, and the fuel beyond your tank stays put anyway. - Even the radio or your windows aren't worth turning the ignition on for. ## Step by step: the fuel drain when our van arrives - Fuel, amount, whether it has run: the answers decide this job, and that is why you get a price after them rather than before. - Clearing it is how that mixture gets taken from your tank. - Rinsing the fuel lines comes next, since a car that ran has petrol past the tank, in the fuel lines themselves. - Your filter is sorted. Cleared, or swapped where the car has a usable one. - Priming comes after fresh diesel is in. - Starting it. After your system is primed with fresh diesel, we start it and confirm it runs properly. Only once it is running on clean diesel do our technicians head off. It's very uncommon for a vehicle spotted soon to be left with lasting damage, and normal use starts again at once. ## Back on the road around Gospel Oak after your fuel drain - Nothing special is needed after a start with fresh diesel — ordinary driving will do. - Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or your throttle stumbling: pull over then call us back. - An insurer, a fleet manager or a hire company may ask what was carried out, and so keep your paperwork. - Next time, go by the pump's label rather than the colour of its handle. ## About Gospel Oak, for a moment Gospel Oak is a suburban area in north London, situated near the River Fleet and overlooking the valley of the same name.
