Motor off. Keep the car that way — no moment on, no moving it at all. Drained and rinsed, just where it is: that is generally all an unrun diesel with petrol in it needs. Whether it stays that straightforward rests on the minutes ahead far more than on everything else. Below is the sequence from this point, wherever around Ranmoor you are. ## Engine off: minute one with petrol in a diesel Before anything else, the following — following this order. - Keys out of the ignition. Switching your ignition on can be all it takes to prime the system, and priming pulls petrol out of the tank towards the parts it damages. Leave it off altogether. - Topping up with diesel sounds like it thins the trouble. It does not: nothing gets out, and the tank just carries more of the same. - Make your car easy to see first — hazard lights on — if there's traffic going past anywhere near you. - The attendants will normally help you push it clear of the petrol pump. Let them, then move it by hand — not under your engine, even for a few yards. - Which fuel, and roughly how much? The receipt replies both, and that is where our first question starts. Do not bin it. Realised on the move? Get off at the next junction if you are on the Tinsley Viaduct, under 10 miles from Ranmoor, and pull over somewhere sensible — not at the services further on. Stage one comes after that. ## Ranmoor fuel drain: has your motor run yet, or not? One answer is what everything after this stage rests on. If your engine hasn't run at all: - The petrol sits in that tank, and only there. - Where the car sits is normally where the work is done: a drain, then a flush. - No spot is better, and it is why the first stage counts so much. Engine run, however briefly? - The lines and the filter now hold petrol drawn from that tank. - The high-pressure pump and the injectors see it too on a longer run. - Lines flushed, your filter seen to, and sometimes more: this job expands as the distance does. Diesel keeps the high-pressure pump and your injectors oiled as it goes through them. Petrol gives them nothing, and that is why the line is drawn there. Nothing is damaged by petrol that's just sitting in a tank. As soon as it's pumped, petrol begins wearing whatever moves it. ## Before you call about petrol in a diesel in Ranmoor: what our engineers need A little preparation is the difference between a van that finds you and a technician that goes round. - S10 3 and the rest of the postcode makes the best way to begin telling us where you are. - Wherever you have parked, the road's name helps — whether that's Ranmoor Crescent 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 mention the landmark — like the one outside Spar. - That it's a diesel, plus the make and model of your vehicle. - Which went in counts: AdBlue is a separate job from petrol, and Ranmoor has a page for it. So say. - How long the nozzle was in, or the litres on the receipt — either tells us how much. - If it's run, how far plus how hard — as well as whether it has run at all. - Whose motor it is. Some hire and company contracts want the owner to approve the work, and that is quicker settled before our engineers arrive than after. Then phone 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — does the trick too. ## Ranmoor fuel drain on its way? Whilst you wait Help, however well meant, is the thing that does the harm whilst you wait. So stick to these. - Safety before your car. If it has stopped somewhere dangerous, get yourself clear of the traffic and wait away from it. If it's safe where it sits, wait with it. - A kind passer-by does not fire it up. Nor does anyone wanting to check it still works, or rolling it a few yards. - No additives. Two-stroke oil, injector cleaner, anything from your boot — none of that gets the petrol back out. - Draining it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond that tank stays where it is all the same. - Leave the ignition off — your windows and the radio included. ## The fuel drain, step by step, after the van gets there - Fuel, quantity, whether it's run: the replies set this job, and that is why we give a price after them rather than before. - The tank is drained. The tainted mix comes from the tank. - The lines are rinsed. If it ran, the petrol has moved beyond your tank, and the lines are carrying it. - Where the vehicle has a serviceable filter, it's changed; otherwise, cleared. - Clean diesel in, and the system primed. - Starting the car. After the system is primed with fresh diesel, our engineers fire it up and confirm it runs properly. Only once it's running on new diesel do our engineers leave. The car returns to normal driving right away, and permanent damage is very uncommon if it has been noticed quickly. ## After the fuel drain is done: driving in Ranmoor again - Nothing unusual is needed after a start with clean diesel — usual driving is all. - Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle tells you to pull over and ring us back. - Keep your paperwork. A hire company, a fleet manager or an insurer may ask what was carried out. - The handle's colour is not the thing to go by next time — the label on the pump is. ## About Ranmoor itself Ranmoor is a suburban area situated near the city of Sheffield in South Yorkshire, with a riverside setting and an elevation of 177 metres.
