Here Is What Happens Whatever you do, don't switch your motor on, even for a moment, to move the car. Stop; leave it off. Emptied and flushed, just where it sits: that's usually all an unrun diesel with petrol in it needs. Whether it remains that straightforward rests on the minutes ahead far more than on anything else. Here's the sequence of things from now, anywhere you're in Wigginton Bottom. ## Petrol in a diesel, motor off — the first minute In this sequence, and before anything else: - The ignition off, keys out. Switched on, your ignition can prime the system — and priming is what moves petrol out of the tank towards the components it harms. - Topping up with diesel sounds like it thins the issue. It does not: nothing gets out, and the tank simply carries more of the same. - Close to moving traffic? Then the hazards come on before anything else, and so the vehicle is easy to spot. - By hand, never under the motor: that is how it leaves the pump. Get the forecourt staff to help you push, whatever the distance. - Keep the receipt. It shows which fuel got in plus roughly how much, which is the first thing we will ask. If you were still on the move when you realised, stop somewhere safe rather than pushing on for the services — on the M1, under 10 miles from Wigginton Bottom, that means the next exit. Step one follows. ## Every Wigginton Bottom fuel drain starts here: has your engine run? What comes next turns on one answer, and just one. If the engine hasn't run at all: - All the petrol remains inside the tank, and just there. - Normally it's drained and flushed right where the car is. - Being here is as good as it gets — which is the whole point of stage one. If it has been started, even for a second: - Some petrol has left the tank by now, gone through your filter, and got into the lines. - On a bigger run it has got to the high-pressure pump as well as the fuel injectors. - Flushing the lines, the fuel filter sorted, and sometimes more: the job grows as the miles does. The reason the line falls there: diesel protects the high-pressure fuel pump as well as your injectors as it passes through them, and petrol doesn't. Nothing is harmed by petrol that's only waiting in a tank. As soon as it is pumped, petrol starts wearing whatever moves it. ## Before you call about petrol in a diesel in Wigginton Bottom: what our engineers need A van that circles against a technician that finds you: a little preparation is the difference. - The ideal start is a postcode — one starting HP23 6 — for where you are. - Give the street — Wigginton Bottom or wherever you have stopped — or the car park. - Name a car park by what it serves — the one outside Tesco, for instance — and it is much quicker to find. - Tell us what the car is — make, model — and confirm it is diesel. - Say which went in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Wigginton Bottom. - How long the nozzle was in, or the litres from the receipt — whichever gives us how much. - If it has run, how far plus how heavily — as well as whether it has run at all. - Hire or company car? Some contracts need the owner's go-ahead for this work, and getting it before our engineers turn up is faster than afterwards. Call 0333 366 0103 next. Email works as well if it can wait, with your car parked at home, going nowhere. ## Waiting for a fuel drain around Wigginton Bottom: what to do Stick to these: kindly meant help causes the damage during the wait. - Safety before the car. If it has stopped somewhere unsafe, get yourself clear of the traffic then wait away from it. If it's safe where it is, wait with it. - Nobody — however kind — starts it, whether to see if it runs or to shift the vehicle a short way. - None of it takes the petrol back out — not two-stroke oil, not injector cleaner, not something from your boot. So no additives. - Siphoning petrol into a can by the kerbside is risky — and it still leaves whatever fuel has already gone beyond your tank. Don't try a home-made drain. - Leave the ignition off — the windows and your radio included. ## Van arrived? Your fuel drain, one step at a time - First, three questions: which fuel got in, the quantity, and has it run? Those replies decide the job, so the price follows them. - Next that tank is cleared, so the tainted fuel is taken out. - Flushing your lines comes next, because a motor that ran has petrol past that tank, in the fuel lines themselves. - Cleared, or swapped if the vehicle has a usable one: the fuel filter is dealt with next. - The fuel system is primed with fresh diesel. - The start. With new diesel in and the system bled, it's fired up and checked to make sure it runs properly. We remain until it is running on new diesel. Permanent damage is very unusual when it has been noticed early, so your car can go right back to normal driving. ## After your fuel drain is done: driving in Wigginton Bottom a second time - Started on new diesel, it needs nothing unusual of you. Just drive normally. - Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle tells you to pull over then ring us back. - An insurer, a fleet manager or a hire firm may ask what was done, and so hold on to your documents. - Next time, check the pump. The label, not the colour of the handle. ## About Wigginton Bottom itself Wigginton Bottom is a suburban area in Hertfordshire, situated inland at an elevation of 196 metres, approximately 28.9 miles from London.
