Stop there. Cleared and cleaned, right where it is: that's generally all an unrun diesel with petrol in it needs. Whether it remains that straightforward depends on the minutes to come far more than on anything else. Anywhere you happen to be in Crofton Park, this is the order things go from now. ## Petrol in a diesel? What to do in minute one Go through the following in sequence, before you do anything else. - Take the keys out. Even your ignition by itself can prime your fuel system, pulling petrol out of your tank to exactly the components it damages, so keep it alone entirely. - Topping up with diesel seems like it thins the trouble. It doesn't: nothing comes out, and the tank just carries more of the same. - Close to passing traffic? Then the hazard lights come on before everything else, and so the car is easy to spot. - Off the pump by hand. At a forecourt, ask the staff to help you push the vehicle clear of the petrol pump. Don't start the vehicle to move it, however short the distance. - Hold on to the till receipt. It shows which fuel was put in plus about how much, which is the first thing we'll ask. On the M11, under 10 miles from Crofton Park, the next exit is the place to leave the car; elsewhere, the first safe place to stop. Don't press on to the services. Then go back to step one. ## Each Crofton Park fuel drain starts here: has your engine run? Everything after this stage rests on one answer. Engine never run at all? - No place but that tank: that is where that petrol yet is. - Normally it is emptied and flushed just where the vehicle stands. - This, here, is the best place to be in, and the whole reason step one matters. If it has been started, even for a moment: - Some petrol has left the tank by now, gone through the filter, and got into the fuel lines. - On a bigger run it has got to your high-pressure pump as well as your injectors. - The farther it went, the larger this job — the lines, your filter, and sometimes more besides. Diesel keeps your high-pressure pump and the injectors protected as it runs through them. Petrol gives them nothing, and that is why the line is drawn there. A tank of petrol, left still, damages nothing. Pump that petrol, though, and it wears the very parts doing the moving. ## Before you call about petrol in a diesel around Crofton Park: what our engineers need Get ready a little, and the technician finds you rather than circling. - Where you have stopped. A postcode starting SE4 1 is the ideal start. - The street or the car park. A road name is a help — Glynde Street, or wherever you have stopped. - Car parks are found most easily by what they serve: tell us the one at Jay's Budgens, and it is simple. - The make and model of the vehicle, and the fact it's a diesel. - Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has its own Crofton Park page. - How much. Litres from the receipt, or how long the nozzle was in the filler. - Whether it has run. And if it has, how far and how heavily. - Hire or company car? Some contracts want the owner's go-ahead for this work, and sorting it before our technicians turn up is faster than afterwards. Phone 0333 366 0103 next. Writing to is fine too if it can wait, with the car parked at home, going nowhere. ## Crofton Park fuel drain on its way? Whilst you wait Hold to these: kindly meant help does the harm during the wait. - Your safety comes before the car. Somewhere exposed? Get away from the traffic then wait away from it. Fine where it sits? Stay with it. - No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll the vehicle a few yards. - Anything from your boot, oil meant for two-strokes or injector cleaner: no additive lifts that petrol. - Emptying it yourself is out: a can of siphoned petrol on a verge is a danger, and the fuel beyond your tank stays put regardless. - Even your radio or the windows are not worth switching your ignition on for. ## Step by step: the fuel drain when our van arrives - The quote comes after three queries, not before them — what was put in, how much, and whether it's run — since those answers shape the job. - That tank is cleared. The polluted blend comes out of the tank. - Rinsing the lines comes next, since a motor that ran has petrol past that tank, inside the lines themselves. - The fuel filter is seen to. Cleared, or replaced where the car has a serviceable one. - Fresh diesel in, and your system primed. - The first start on fresh diesel. When priming is finished, your engine is fired up and our technicians confirm that it runs correctly. Till it runs on fresh diesel, our technicians stay with it. If it has been noticed quickly, lasting damage is very unusual, and the vehicle goes back to normal driving right away. ## Back on the road in Crofton Park after your fuel drain - Nothing unusual is needed after a start with clean diesel — usual driving will do. - Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or your throttle stumbling: pull over then ring us back. - Keep the paperwork. A hire company, a fleet manager or an insurer may ask what was carried out. - Next time, trust the petrol pump's label instead of the colour of its handle. ## About Crofton Park, briefly Crofton Park is a suburban area in south east London, situated near the River Ravensbourne at an elevation of around 28 metres.
