Pause; leave the vehicle off. Drained and rinsed, just where it sits: that is generally all an unrun diesel with petrol in it takes. Whether it remains that simple rests on the minutes to come far more than on anything else. Anywhere you are around Wigston Magna, here is the order things go from here. ## Petrol in a diesel, engine off — the first minute Work through these first, in this sequence. - Bleeding your fuel system pulls petrol from the tank towards the components it damages, and turning your ignition on can be all it takes to do that. So your keys get taken out, and the ignition stays off altogether. - Don't top it up with diesel. Adding diesel removes nothing. You end up with a bigger tank of the same mixture. - Near moving traffic? Then the hazards go on before anything else, so your car is easy to see. - By hand, not under the motor: that's how it comes off the petrol pump. Get the forecourt staff to help you push, whatever the distance. - Which fuel, and about how much? The receipt answers that, and that is where our first question starts. Do not throw it away. If you were still driving when you realised, pull over somewhere safe rather than pushing on for the services — on the M1, under 5 miles from Wigston Magna, that means the next junction. Stage one follows. ## Wigston Magna fuel drain: has your motor run yet, or not? Everything after this stage rests on one answer. Motor never run at all? - Just the tank has petrol in it so far. - Usually it is emptied and flushed right where your car stands. - This is the best case — which is the whole point of step one. If it has been started, even for a second: - Out of that tank, through your filter, into the fuel lines: that is how far that petrol has got. - Your high-pressure pump and the fuel injectors get it on a bigger run. - Lines flushed, your filter sorted, and sometimes more: this job grows as the miles does. Why the line falls there: diesel protects the high-pressure fuel pump and the injectors as it passes through them, and petrol does not. Nothing is damaged by petrol that is just resting in a tank. Move the petrol, though, and it grinds down the very parts that move it. ## Wigston Magna, petrol in a diesel: have these prepared before you call Get ready a little, and the technician finds you instead of circling. - LE18 3 plus the rest of the postcode makes the ideal way to start telling us where you are. - Wherever you have parked, the road's name is useful — whether that's Sywell Drive or somewhere else — and so does the name of a car park. - Or the nearest landmark. A car park is easier to find by what it serves, like the one outside Aldi. - The vehicle. Make, model, and that it is a diesel. - Which was put in counts: AdBlue is a separate job from petrol, and Wigston Magna has a page just for that. So tell us. - How much. Litres from the receipt, or how long the nozzle was in. - If it's run, how far plus how hard — and whether it has run at all. - Sort who owns your car before we arrive: some hire and company agreements want the owner to authorise this work, and that is quicker beforehand. Call 0333 366 0103 once you've got that ready — or, if the vehicle is at home, going nowhere, use . ## Wigston Magna fuel drain on its way? While you wait The wait is where kindly meant help does the harm. Stick to these. - Safety before the vehicle. If it has stopped somewhere exposed, get yourself away from the traffic and wait away from it. If it's safe where it sits, wait with it. - A kind passer-by doesn't crank it. Nor does anybody checking it still works, or moving it a few yards. - Something from the boot, oil meant for two-strokes or injector cleaner: no additive removes that petrol. - A DIY drain leaves your fuel already gone beyond your tank, and siphoning petrol by the road is hazardous too. - Not for your radio, not for your windows: your ignition remains off. ## The fuel drain, step by step, once our van gets there - First, three questions: which fuel was put in, the quantity, and has it run? Those answers decide the job, and so our price follows them. - Out of the tank comes the polluted mixture: your tank is drained. - The lines are purged. If it ran, the petrol has shifted beyond that tank, and the fuel lines are carrying it. - The fuel filter is dealt with. Cleared, or swapped where the car has a usable one. - Clean diesel goes in, then your system is primed. - Our technicians start the car only after fresh diesel has gone in and bled your system, then make sure that it's running correctly. Only when it's running on clean diesel do we head off. It's very rare for a car noticed soon to be left with permanent damage, and normal driving starts again straight away. ## Wigston Magna, after your fuel drain: back on the road - Drive normally. There's nothing special to do once it's been started on fresh fuel. - Pull over and ring us back if anything seems wrong early on — a light on your dash, smoke from your exhaust, an idle that is lumpy, or a throttle with a dead spot. - The work may come up later with a hire firm, an insurer or a fleet manager. Keep the documents. - The handle's colour is not the guide to go by next time — the label on the pump is. ## About Wigston Magna, for a moment Wigston Magna is a suburban area in Leicestershire, situated approximately 3.9 miles south of Leicester.
