Motor off. Keep the vehicle that way — no moment on, no moving it anywhere. The coming few minutes decide it more than anything else: petrol in a diesel still unrun normally comes down to draining then rinsing, on the spot. Wherever you happen to be in Tattenhoe Park, this is the order things go from here. ## Petrol in a diesel, engine off — the first minute Work through these first, in this sequence. - Keys out of the ignition. Turning your ignition on can be all it takes to prime the fuel system, while priming draws petrol out of your tank towards the components it damages. Keep the vehicle off altogether. - Topping up with diesel seems like it dilutes the problem. It doesn't: nothing gets out, and the tank just carries more of the same. - Make the car easy to see before anything else — hazard lights on — if there is moving traffic anywhere near you. - Off the pump by hand. At a forecourt, get the attendants to help you roll the car clear of the pump. Do not crank it to shift it, however short the way. - The first thing you will be asked is which fuel you put in and about how much — and the receipt says both. Keep it. Still on the move when you realised? Come off the M1 at the next junction if that's where you are, under 10 miles from Tattenhoe Park, and pull over somewhere safe and not pushing on to the services. Then start at stage one. ## Tattenhoe Park fuel drain: has your engine run yet, or not? Everything after this point depends on one answer. If the engine hasn't run at all: - Only the tank has petrol in it for now. - Where the vehicle stands is usually where this work is done: a drain, then a flush. - This, here, is the best position to be in, and the whole reason stage one counts. If the engine has run, even for a moment: - Out of your tank, through the fuel filter, into your lines: that is how far the petrol has travelled. - A bigger run takes it all the way to the high-pressure fuel pump and your injectors. - The job grows with the mileage — lines cleaned, filter seen to, sometimes more. That line falls there since diesel lubricates your high-pressure pump and your injectors on its way through them — and petrol does not. A tank of petrol, left still, damages nothing. As soon as it's pumped, petrol starts wearing whatever moves it. ## Tattenhoe Park, petrol in a diesel: have these ready before you call A little preparation is the difference between a van that finds you and a technician that goes round. - MK4 4 plus the rest of the postcode is the ideal way to start telling us where you are. - Wherever you have pulled up, the road's name is useful — whether that is Verne Grove or somewhere else — and so does the name of a car park. - Car parks are located more easily by what they serve: say the one at Morrisons, and it is straightforward. - Say what your car is — make, model — and confirm it is diesel. - Say which was put in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Tattenhoe Park. - How long the nozzle was in, or the litres on the receipt — whichever gives us how much. - Whether it's run. And if it has, how far and how heavily. - Whose motor it is. Some hire or company agreements want the owner to approve the work, and that's quicker settled before our technicians get there than after. Next, 0333 366 0103. Not pressing, the car parked at home with nowhere to be? Then will do as well. ## Waiting for a fuel drain around Tattenhoe Park: what to do During the wait, the harm comes from well-meant help — which is why these count. - Stay 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. - A kind passer-by doesn't crank it. Nor does anyone wanting to check it still does the trick, or rolling it a few yards. - None of that gets the petrol back out — not two-stroke oil, not injector cleaner, not something from your boot. So no additives. - Emptying it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and the fuel beyond the tank remains where it is all the same. - Leave your ignition off — your windows and your radio included. ## When the van arrives: your fuel drain, step by step - Fuel, amount, whether it's run: the replies decide this job, and that is why you get a price after them instead of before. - The tank is cleared. The polluted mix comes out of the tank. - The lines are cleaned. If it ran, that petrol has moved beyond the tank, and the lines are carrying it. - The fuel filter is dealt with. Cleared, or replaced where the vehicle has a serviceable one. - Fresh diesel goes in, then the system is primed. - The start-up. With fresh diesel in and the fuel system bled, it is fired up and tested to be sure it runs smoothly. We stay until it's running on new diesel. If it has been spotted soon, lasting damage is very unusual, and your car goes back to normal driving at once. ## After the fuel drain is done: driving in Tattenhoe Park a second time - Nothing unusual is needed after a start with fresh diesel — ordinary driving will do. - Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or your throttle hesitating: pull over and call us back. - The paperwork covers the query a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Next time, go by the pump's label rather than the colour of its handle. ## About Tattenhoe Park and where it is Tattenhoe Park is a suburban area in Buckinghamshire, situated approximately 4 miles west of Milton Keynes and 44 miles northwest of London.
