Emptied and rinsed, right where it is: that is generally all an unrun diesel with petrol in it needs. Whether it remains that straightforward depends on the minutes ahead far more than on everything else. Below is the order from here, wherever in Shortheath you happen to be. ## Petrol in a diesel, motor off — the first minute Before anything else, these — following this order. - The ignition off, keys out. Turned on, the ignition can prime the system — and priming is what moves petrol out of your tank into the parts it harms. - No diesel on top. More fuel in removes none of the petrol — it just leaves you with extra of the same mixture. - Hazard lights on. If you are anywhere near moving traffic, make the vehicle easy to see before you do anything else. - The staff will normally help you roll it clear of the petrol pump. Let them, and roll it by hand — not under your engine, even for a few yards. - Hold on to the receipt: the fuel and the rough amount are written on it, and they are what our technicians ask for first. On the M3, under 10 miles from Shortheath, the next junction is the place to leave the car; anywhere, the first safe location to stop. Don't press on to the services. Then go back to step one. ## Has it run yet? The fork in each Shortheath fuel drain Everything after this stage rests on one answer. If it has never been started: - No place but that tank: that's where that petrol still is. - The work is a simple drain and a flush, usually done where your car is. - No position is better, and it is why the first step counts so much. Run at all, however briefly: - From your tank, past the filter, into your lines: that's how far the petrol has travelled. - The high-pressure fuel pump as well as the fuel injectors get it on a bigger run. - The further it went, the larger the job — the lines, your filter, and sometimes more besides. The reason the line falls there: diesel lubricates the high-pressure fuel pump as well as the injectors as it passes through them, and petrol does not. Petrol sitting in a tank damages nothing. The components that shift it are grinding the moment petrol is being pumped. ## Calling about petrol in a diesel from Shortheath: what to have ready Get ready a little, and the van finds you rather than circling. - GU9 8 and the rest of the postcode makes the best way to begin telling us where you are. - Name the street — Sunnydell Lane or wherever you have stopped — or the car park. - What a car park serves is the quickest way to find it, and so mention the landmark — like the one at Co-op Food. - That it is a diesel, along with the make and model of your car. - Which was put in matters: AdBlue is a separate job from petrol, and Shortheath has a page for it. So tell us. - Roughly how much — in litres from your receipt, or by how long the nozzle stayed in. - If it has run, how far and how hard — and if it's run at all. - Settle who has your car ahead of when we turn up: some hire and company agreements want the owner to approve the work, and doing it faster first. Next, 0333 366 0103. Not time-critical, the car parked at home with nowhere to be? Then works too. ## The wait for a Shortheath fuel drain, and what to do in it In the wait, the damage comes from well-meant help — so these count. - Your safety comes before the vehicle. Somewhere unsafe? Get away from the traffic and wait away from it. Fine where it stands? Wait with it. - Not to roll it a few yards, not to check it is all right, not for a passer-by's kindness: nobody starts it. - Anything from your boot, oil made for two-strokes or injector cleaner: no additive lifts that petrol. - A home-made drain leaves the fuel that has already gone beyond the tank, and siphoning petrol by the road is hazardous besides. - Leave your ignition off — the windows and your radio too. ## Van arrived? The fuel drain, one step at a time - First, three questions: which fuel went in, the quantity, and has it run? Those replies decide the job, so the quote follows them. - Your tank is emptied. The contaminated mixture comes from that tank. - The lines are rinsed. If it ran, that petrol has moved beyond your tank, and your lines are carrying it. - Where the car has a workable filter, it is changed; otherwise, cleared. - Clean diesel in, and your system primed. - The start. With new diesel in and the fuel system bled, it is started and tested to confirm it runs smoothly. Till it runs on new diesel, we stay with it. The vehicle goes back to normal driving right away, and lasting damage is very unusual if it has been spotted soon. ## After your fuel drain is done: driving around Shortheath once more - Once it's been started on fresh fuel, there's nothing special to do: drive normally. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop and call us again. - The paperwork answers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Next time, read the petrol pump. The label, not the colour of the handle. ## About Shortheath itself Shortheath is a village in Surrey, situated on the riverside at an elevation of 112 metres, with detached housing being the predominant type of accommodation.
