Hasn't been run? Then petrol in a diesel tends to be a straightforward drain-and-flush job wherever your vehicle has stopped — and no other factor decides that as much as the next few minutes do. Below is the order from here, anywhere in Lacey Green you are. ## Petrol in a diesel? What to do in minute one Do the following before anything else, in this sequence. - Pull the keys out. Even the ignition on its own can prime the system, pulling petrol out of the tank to exactly the components it damages, so keep it alone completely. - Topping up with diesel sounds like it thins the issue. It doesn't: nothing comes out, and the tank just carries more of the same. - Make the vehicle easy to see before anything else — hazard lights on — if there is traffic going past anywhere near you. - However short the distance, starting it to shift it is the mistake. At a forecourt, roll the car clear of the pump by hand instead, then ask the attendants to help. - Hold on to your receipt. It says which fuel was put in plus about how much, which is the first thing we will ask. Noticed on the move? Get off at the next exit if you are on the M40, under 5 miles from Lacey Green, and stop somewhere sensible — not at the services farther on. Stage one comes after that. ## Lacey Green fuel drain: has your engine run yet, or not? What happens after this turns on one answer, and only one. Motor never run at all? - Just the tank has petrol in it so far. - The work is a simple drain and a flush, usually done where the car is. - Stage one counts for precisely this reason: it's the best spot to be in. If the motor has run, even briefly: - Some petrol has left your tank already, passed through the filter, and got into the lines. - Your high-pressure pump and your injectors see it too on a longer run. - The farther it went, the larger this job — the fuel lines, the fuel filter, and sometimes more besides. That line falls there because diesel lubricates your high-pressure pump and your injectors on its way through them — and petrol doesn't. Nothing is harmed by petrol that's only resting in a tank. Petrol being pumped is wearing the components that move it. ## Before you call about petrol in a diesel in Lacey Green: what our engineers need A little preparation is the difference between a van that finds you and a van that goes round. - Where you are. A postcode starting HP27 0 is the best start. - Wherever you have parked, the road's name is useful — whether that is Kiln Lane or somewhere else — and so does the name of a car park. - Car parks are found more easily by what they serve: say the one outside The Co-operative Food, and it's straightforward. - The make and model of your car, and the fact it is a diesel. - Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has a separate Lacey Green page. - Roughly how much — in litres from your receipt, or by how long the nozzle was in. - If it has run, how far plus how hard — as well as whether it has run at all. - Settle who has the car ahead of when our engineers turn up: some hire or company agreements want the owner to approve this work, and that is faster first. Ring 0333 366 0103 next. Email works too if it can wait, with the car parked at home, going nowhere. ## Waiting for a fuel drain around Lacey Green: what to do The wait is where kindly meant help does the damage. Stick to these. - Wait with the vehicle if it's safe where it is — but if it has stopped somewhere dangerous, you come first: away from the traffic, waiting apart from it. - Not to roll it a couple of yards, not to check it is all right, not as a passer-by's favour: nobody starts it. - Something from the boot, oil made for two-strokes or injector cleaner: no additive removes that petrol. - A home-made drain leaves your fuel already gone beyond that tank, and siphoning petrol by the road is risky too. - Even the radio or the windows aren't worth switching the ignition on for. ## Step by step: your fuel drain when our van gets there - Three queries. What got in, how much, and if it has run. Those replies shape the job, which is why the quote comes after them but not before. - Then the tank is drained, so the contaminated fuel comes out. - The fuel lines are purged. If it ran, the petrol has shifted beyond your tank, and your lines are holding it. - Where your car has a usable filter, it is replaced; otherwise, cleared. - Fresh diesel in, and the fuel system primed. - The start-up. With clean diesel in and the fuel system primed, it's fired up and tested to confirm it runs properly. Only when it is running on new diesel do our technicians leave. If it has been spotted early, lasting damage is very rare, and the car goes back to normal use at once. ## Back on the road around Lacey Green after the fuel drain - Drive normally. There is nothing special to do after it has been started on clean fuel. - Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or your throttle stumbling: pull over and call us back. - Your paperwork covers 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 Lacey Green and where it is Lacey Green is a small village in Buckinghamshire, situated in the Chiltern Hills at an elevation of 221 metres.
