Engine off. Leave the car like that — no moment on, no moving it at all. Emptied then flushed, right where it sits: that's normally all an unrun diesel with petrol in it takes. Whether it remains that simple rests on the minutes to come more than on everything else. Below is the order from this point, wherever in Deepcar you are. ## Engine off: minute one with petrol in a diesel Go through the following in sequence, first. - Keys out of your ignition. Switching the ignition on can be all it takes to prime your fuel system, and priming pulls petrol out of the tank towards the components it damages. Keep it off completely. - Do not top it up with diesel. Adding diesel removes nothing. You end up with a bigger tank of the same mixture. - Near moving traffic? Then your hazards go on before anything else, and so the car is easy to see. - However short the way, starting it to shift it is the mistake. On a forecourt, push the car clear of the petrol pump by hand instead, then ask the attendants to help. - Which fuel, and about how much? The receipt answers both, and that is where our first question starts. Never throw it away. If you were still on the move when you noticed, stop somewhere safe rather than pushing on for the services — on the M1, under 5 miles from Deepcar, that means the next exit. Step one follows. ## Has it run yet? The fork in every Deepcar fuel drain What comes next rests on one answer, and just one. If it has never been started: - The petrol is still inside the tank and nowhere else. - Usually it is emptied and flushed right where the vehicle is. - This is as good as it gets — which is the entire point of stage one. If it has been started, even for a second: - Some petrol has left the tank already, passed through the filter, and reached the fuel lines. - On a bigger run it has got to your high-pressure pump and your injectors. - Miles is what makes it a larger job: the lines flushed, a filter seen to, and at times further work. The reason the line falls there: diesel protects the high-pressure fuel pump and the fuel injectors as it flows through them, and petrol does not. A tank of petrol, left alone, hurts nothing. Pump that petrol, though, and it grinds down the very parts that move it. ## Calling about petrol in a diesel from Deepcar: what to have ready Get ready a little, and the technician finds you rather than circling. - The best start is a postcode — one starting S36 2 — for where you are. - Give the street — St John's Road or wherever you have stopped — or the car park. - Or the landmark. A car park is quicker to find by what it serves, such as the one outside Aldi. - The car. Make, model, plus that it's a diesel. - What got in. Petrol, or AdBlue. AdBlue is a different job with its own page for Deepcar, so say which. - About how much — in litres from the receipt, or by how long the nozzle stayed in. - Has it run? If so, say how far it went, and how it was driven. - The owner may have to authorise the work under some hire and company agreements — so it's faster to settle whose motor it is before our engineers get there. Phone 0333 366 0103 once you have got that together — or, if your car is at home, going nowhere, use . ## The wait for a Deepcar fuel drain, and what to do in it Help, however well meant, is what does the harm while you wait. So stick to these. - Stay with the car if it is safe where it is — but if it has stopped somewhere dangerous, you come first: away from the traffic, waiting apart from it. - No one — however helpful — starts it, whether to see if it runs or to move your car a short way. - Something from your boot, oil meant for two-strokes or injector cleaner: no additive removes that petrol. - No home-made emptying. Siphoning petrol into a can by the kerbside is dangerous, and it leaves the fuel that has by now gone beyond your tank. - Ignition stays off. Even for the radio or your windows. ## Van arrived? The fuel drain, one step at a time - Three queries. What got in, how much, and whether it has run. The replies shape this job, which is why our price comes after them and not before. - Out of your tank comes the tainted mix: the tank is emptied. - If it ran, the lines are carrying petrol that has moved beyond the tank — so they're rinsed. - The fuel filter is seen to. Cleared, or swapped where the car has a usable one. - Priming follows after clean diesel is in. - Starting up. When the system is bled with fresh diesel, our engineers fire it up and check it runs correctly. The car has fresh diesel running through it before our engineers leave. It is very rare for a car noticed quickly to be left with lasting damage, and normal driving resumes straight away. ## Deepcar, after the fuel drain: back on the road - Nothing special is needed after a start with fresh diesel — normal driving will do. - Pull over and ring us back if anything looks wrong early on — a light on your dash, smoke from the exhaust, an idle that runs rough, or a throttle with a dead spot. - An insurer, a fleet manager or a hire firm may ask what was carried out, so hold on to your documents. - The handle's colour is not the guide to go by next time — the label on the pump is. ## About Deepcar Deepcar is a village situated on the River Don in South Yorkshire, with a mix of rural and suburban characteristics.
