Stop there. Drained then flushed, right where it sits: that's usually all an unrun diesel with petrol in it needs. Whether it stays that straightforward rests on the minutes ahead more than on everything else. Wherever you are around Lilypool, this is the order things run from here. ## Petrol in a diesel? What to do in minute one In this sequence, all before anything else: - Bleeding the fuel system pulls petrol from your tank toward the parts it harms, and switching your ignition on can be all it takes to do that. So your keys get taken out, and the ignition stays off completely. - No diesel on top. More fuel in removes none of the petrol — it just makes you with extra of the same mixture. - Visibility comes before the rest beside moving traffic: put the hazard lights on, and only then think about everything else. - Off the petrol pump by hand. At a forecourt, get the staff to help you push the vehicle away from the pump. Don't start it to shift it, however short the way. - The first thing we will ask is which fuel went in and about how much — and the till receipt shows both. Keep it. If you were still on the move when you noticed, stop somewhere sensible rather than pushing on for the services — on the M1, under 5 miles from Lilypool, that means the next exit. Step one follows. ## Lilypool fuel drain: has your motor run yet, or not? What comes after this rests on one answer, and only one. If the engine has not run at all: - No place but that tank: that is where that petrol yet is. - Draining and flushing, on the spot, is normally the whole job. - Step one counts for precisely this reason: it's the best spot to be in. If it's been started, even for a second: - Out of the tank, through the filter, into your lines: that is how far the petrol has got. - A bigger run carries it right through to the high-pressure pump and the injectors. - The farther it went, the bigger the job — the lines, the filter, and sometimes more besides. The reason the line falls there: diesel protects the high-pressure fuel pump as well as the fuel injectors as it flows through them, and petrol does not. In the tank, sitting still, petrol harms nothing. Once it's pumped, petrol starts wearing down whatever moves it. ## What to have ready when you call about petrol in a diesel from Lilypool Get ready a little, and the technician finds you instead of circling. - Your whereabouts: a postcode starting DE73 8 works best. - The road or the car park. A road name is a help — Tivey Way, or wherever you have stopped. - Describe a car park by what it serves — the one at Aldi, for example — and it's far easier to find. - That it is a diesel, along with the make and model of your car. - Which was put in counts: AdBlue is a separate job from petrol, plus Lilypool has a page just for that. So tell us. - Roughly how much — in litres from the receipt, or by how long the nozzle stayed in. - Whether it's run. And if it has, how far and how hard. - Whose car it is. Some hire or company contracts want the owner to authorise this work, and that's easier settled before our engineers get there than after. Then phone 0333 366 0103. If it can wait — the car is at home with going nowhere — works too. ## The wait for a Lilypool fuel drain, and what to do in it During the wait, the damage comes from well-meant help — so these matter. - Stay with the vehicle if it is safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it. - A helpful passer-by doesn't start it. Nor does anybody wanting to check it still does the trick, or moving it a couple of yards. - No additives. Two-stroke oil, injector cleaner, anything from the boot — none of that gets the petrol back out. - Emptying it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond your tank stays where it is anyway. - The ignition stays off. Even for the radio or your windows. ## The fuel drain, step by step, after the van arrives - First, three queries: which fuel went in, the amount, and has it run? Those replies decide the job, and so the quote follows them. - Emptying it's how the blend gets taken from your tank. - Petrol that has moved beyond your tank sits in your lines once it ran, and your lines are rinsed to clear it. - Cleaned, or replaced if the car has a workable one: the filter is dealt with next. - The fuel system is primed with clean diesel. - Our engineers start it only after new diesel has gone in and bled the fuel system, then make sure that it's running properly. The car has clean diesel running through it before our engineers leave. Long-term damage is very uncommon when it has been noticed quickly, so your car can go straight back to normal use. ## Back on the road in Lilypool after the fuel drain - Nothing special is needed after a start with clean diesel — usual driving will do. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your cue to stop and ring us a second time. - The work may matter later with a hire firm, an insurer or a fleet manager. Hold on to your paperwork. - The handle's colour is not the thing to go by next time — the label on the pump is. ## About Lilypool itself Lilypool is a suburban area in Derbyshire, situated approximately 7 miles from Derby and 106 miles from London, with a population of around 3560 residents.
