Next Steps canonical: https://www.petrolinadieselcar.co.uk/petrol-in-diesel/shottermill-surrey/ location: Shottermill county: Surrey latitude: 51.089240 longitude: -0.743610 service: Petrol in a Diesel Car updated: 2026-10-16 --- # What Happens Now: Petrol in a Diesel Car in Shottermill Whatever you do, don't switch your motor on, even briefly, to shift it. Stop; leave it off. The coming few minutes determine it far more than anything else: petrol in a diesel that has not run generally amounts to emptying and rinsing, right there. From now on, in order, wherever you are in Shottermill: ## Petrol in a diesel, motor off — the first minute Work through these in order, before you do anything else. - Ignition off, keys out. Turned on, your ignition can prime the system — and priming is what draws petrol out of the tank into the components it damages. - Do not top it up with diesel. Adding diesel takes out nothing. You end up with a bigger tank of the same mixture. - Visibility comes first near moving traffic: put the hazards on, and only then deal with everything else. - However short the distance, starting it to move it is the thing to avoid. At a forecourt, push the car clear of the petrol pump by hand instead, and ask the staff to help. - Keep your receipt. It says which fuel went in and roughly how much, which is the first thing we'll ask. Noticed on the move? Get off at the next exit if you are on the M3, under 15 miles from Shottermill, and pull over somewhere sensible — not at the services further on. Step one comes after that. ## The fork in every Shottermill fuel drain: has it run yet? What comes after this turns on one answer, and only one. If it has never been started: - The petrol is still inside the tank and nowhere else. - Where your car stands is usually where this work is done: a drain, then a flush. - This is the best place to be in, and the whole reason step one matters. If the motor has been run, even briefly: - Petrol has been drawn from the tank, through the filter and into your lines. - A longer run carries it right through to the high-pressure fuel pump and the injectors. - The further it went, the bigger this job — your lines, the filter, and now and then more besides. The line falls there because diesel lubricates the high-pressure fuel pump and the injectors on its way through them — and petrol does not. A tank of petrol, left alone, hurts nothing. Once it's pumped, petrol begins grinding whatever moves it. ## What to have prepared when you call about petrol in a diesel from Shottermill Get ready a little, and the technician finds you rather than circling. - The ideal start is a postcode — one starting GU27 1 — for where you have stopped. - Name the road — Oak Cottages or wherever you have pulled up — or the car park. - Car parks are found more easily by what they serve: tell us the one at M&S Foodhall, and it's simple. - The car. Make, model, and that it is a diesel. - Tell us which went in — petrol or AdBlue — since AdBlue is a separate job, with a page of its own for Shottermill. - Roughly how much — in litres from the receipt, or by how long the nozzle was in. - Has it run? If so, say how far it got, and the way it was driven. - The owner may have to approve this work under some hire and company agreements — so it is faster to settle whose car it is before our technicians arrive. Ring 0333 366 0103 once you have got that ready — or, if the car is at home, going nowhere, use . ## Waiting for a fuel drain in Shottermill: what to do In the wait, the harm comes from kindly meant help — which is why these matter. - Safety before the vehicle. If it has stopped somewhere unsafe, get yourself away from the traffic and wait away from it. If it is safe where it sits, wait with it. - Not to roll it a few yards, not to check it is all right, not as a passer-by's kindness: nobody starts it. - Anything from your boot, oil meant for two-strokes or injector cleaner: no additive lifts the petrol. - A home-made drain leaves your fuel already gone beyond that tank, and siphoning petrol by the road is hazardous besides. - Ignition remains off. Even for the radio or the windows. ## Step by step: the fuel drain when our van gets there - First, three queries: which fuel got in, the volume, and has it run? Those answers shape the job, so the price follows them. - Out of that tank comes the tainted mixture: the tank is drained. - If it ran, your lines are holding petrol that has shifted beyond your tank — so they're flushed. - The filter is seen to. Cleared, or replaced where your car has a usable one. - Clean diesel in, and the fuel system primed. - Starting up. After the fuel system is primed with clean diesel, our engineers start the car and make sure it runs properly. Only once it's running on clean diesel do our technicians go. Your car returns to normal use right away, and long-term damage is very rare when it has been spotted quickly. ## After the fuel drain is done: driving around Shottermill once more - Drive normally. There is nothing unusual to do once it's been started on clean fuel. - Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or the throttle stumbling: pull over then ring us back. - The paperwork answers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Read the label on the petrol pump next time, not the colour of the handle. ## About Shottermill and where it is Shottermill is a suburban area in Surrey, situated near the River Wey and surrounded by wooded hills.
