Pause; leave it off. The coming few minutes decide it more than anything else: petrol in a diesel still unrun usually comes down to emptying and purging, on the spot. From here on, in order, wherever you are around Walton: ## Petrol in a diesel, motor off — the first minute Go through these in order, before you do anything else. - Priming your fuel system draws petrol from the tank toward the components it harms, and turning your ignition on can be all it takes to do that. So the keys come out, and your ignition stays off altogether. - Topping up with diesel sounds like it thins the trouble. It doesn't: nothing comes out, and the tank just carries more of the same. - Hazards on. If you are at all near moving traffic, make your car simple to see before you do anything else. - By hand, never on the motor: that is how it comes off the pump. Get the forecourt staff to help you push, however short the miles. - Keep the receipt: the grade and the rough amount are printed on it, and they are what we ask about first. Noticed on the move? Get off at the next exit if you're on the A1(M), under 10 miles from Walton, and stop somewhere safe — not at the services further on. Step one starts after that. ## Every Walton fuel drain starts here: has the motor run? What happens after this turns on one answer, and only one. Motor not run at all? - Just that tank has petrol in it for now. - Where your car sits is normally where this work is done: a drain, then a flush. - No spot is better, and it is why the first step matters so much. If it has been started, even for a second: - Some petrol has left that tank by now, passed through the fuel filter, and got into your lines. - A longer run carries it right through to the high-pressure pump and the injectors. - Lines flushed, your filter sorted, occasionally more: this job grows as the distance does. Petrol doesn't lubricate. Diesel does, oiling the high-pressure pump and injectors as it passes through, which is why the line falls where it does. A tank of petrol, left alone, damages nothing. Once it's pumped, petrol begins wearing whatever moves it. ## Calling about petrol in a diesel from Walton: what to have prepared Prepare a little, and the van finds you rather than circling. - The ideal start is a postcode — one beginning PE4 6 — for where you are. - The road or the car park. A road name helps — Mountsteven Avenue, or wherever you have stopped. - Name a car park by what it serves — the one outside Morrisons, for instance — and it is much easier to find. - That it is a diesel, along with the make and model of the vehicle. - Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has a separate Walton page. - How much. Litres from the receipt, or how long the nozzle was in the filler. - The distance it covered, and how hard, if it has run at all. - Whose car it is. Some hire and company agreements want the owner to approve this work, and that's easier settled before we turn up than after. Call 0333 366 0103 once you've got that together — or, if your car is at home, going nowhere, use . ## While you wait for a fuel drain in Walton The wait is where well-meant help does the damage. Stick to these. - 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 sits, wait with it. - Not to roll it a few yards, not to check it is all right, not as a passer-by's kindness: nobody starts it. - Anything from your boot, oil made for two-strokes or injector cleaner: no additive lifts the petrol. - Emptying it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and the fuel beyond that tank stays put anyway. - Not for the radio, not for the windows: the ignition stays off. ## When the van gets there: the fuel drain, step by step - Fuel, amount, whether it has run: those replies set this job, and that's why you get a quote after them instead of before. - Draining it is how that blend gets taken from that tank. - Rinsing your lines comes next, because a motor that ran has petrol past the tank, inside the fuel lines themselves. - Where the vehicle has a workable filter, it is replaced; if not, cleared. - Fresh diesel in, and your system primed. - Our engineers start the car only after clean diesel has gone in and primed the fuel system, then make sure that it is running correctly. Our engineers stay until it's running on clean diesel. When it has been noticed soon, permanent damage is very rare, and the car goes back to normal use at once. ## Back on the road in Walton after the fuel drain - Nothing special is needed after a start with clean diesel — usual driving will do. - Watch the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle tells you to pull over then ring us back. - The work may matter later with a hire firm, an insurer or a fleet manager. Keep your paperwork. - Next time, check the petrol pump. The label, not the colour of its handle. ## About Walton Walton is a suburban area located on the riverside in Cambridgeshire, with an elevation of around 15 metres.
