Here Is What Happens Pause, and keep your engine off — not on, and not for a moment to shift the vehicle. Petrol in a diesel that has not been run is generally a drain and a flush, done right where your vehicle sits, and what happens in the next few minutes determines that far more than anything else. Anywhere you happen to be around Wellesbourne, this is how things run from now. ## Petrol in a diesel, motor off — the first minute In this order, all before everything else: - The ignition off, keys out. Turned on, the ignition can prime your system — and priming is what moves petrol out of the tank into the components it damages. - Do not top it up with diesel. Adding diesel removes nothing. You end up with a bigger tank of the same mixture. - Hazard lights on. If you are at all near moving traffic, make the car simple to see before you do anything else. - By hand, never under the motor: that's how it comes off the pump. Ask the forecourt staff to help you roll, whatever the miles. - Which fuel, and about how much? Your receipt answers both, and that's where our questions start. Never throw it away. If you were still on the move when you realised, pull over somewhere sensible instead of pushing on for the services — on the M40, under 5 miles from Wellesbourne, that means the next junction. Step one comes next. ## Has it run yet? The fork in each Wellesbourne fuel drain Everything after this point rests on one answer. Engine not run at all? - Nowhere but your tank: that is where that petrol still is. - The job is a simple drain and a flush, normally done where the car stands. - Being here is the best case — which is the whole point of stage one. If it's been started, even for a second: - Petrol has been drawn out of the tank, past the fuel filter and into your lines. - On a longer run it has reached the high-pressure fuel pump and the fuel injectors. - The farther it went, the larger the job — your lines, the fuel filter, and sometimes more besides. The line falls there because diesel protects the high-pressure pump and the fuel injectors on its way through them — and petrol doesn't. A tank of petrol, left still, hurts nothing. Petrol being pumped is wearing the components that move it. ## Calling about petrol in a diesel from Wellesbourne: what to have ready A little planning is the difference between a technician that finds you and a van that circles. - Your whereabouts: a postcode starting CV35 9 works best. - Wherever you have pulled up, the road's name helps — whether that's Bridge Street or somewhere else — and so does the name of a car park. - Car parks are found most easily by what they serve: say the one outside The Co-operative Food, and it's easy. - That it is a diesel, along with the make and model of your vehicle. - Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has a separate Wellesbourne page. - The quantity: your receipt's litres, or else how long you had the nozzle in. - Whether it's run. And if it has, how far plus how hard. - Sort who owns the vehicle before our technicians arrive: some hire or company contracts want the owner to authorise the work, and that is quicker beforehand. Then ring 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — works too. ## The wait for a Wellesbourne fuel drain, and what to do in it Help, however well meant, is the thing that does the damage while you wait. So hold to these. - Stay with the vehicle if it's safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it. - Not to roll it a few yards, not to check it is all right, not for a passer-by's favour: no one starts it. - No additives. Two-stroke oil, injector cleaner, something from your boot — none of that gets that petrol back out. - A DIY drain misses your fuel already gone beyond your tank, and siphoning petrol by the road is dangerous too. - Not for the radio, not for the windows: your ignition stays off. ## When the van arrives: your fuel drain, step by step - First, three queries: which fuel got in, the amount, and has it run? Those answers shape this job, and so the quote follows them. - Your tank is cleared. The tainted mixture comes out of your tank. - Rinsing your lines comes next, since a motor that ran has petrol past the tank, in your lines themselves. - Your filter is seen to. Cleared, or replaced where the car has a workable one. - The fuel system is primed with clean diesel. - The first start on new diesel. Once bleeding is complete, your engine is started and our technicians confirm that it runs properly. Only once it's running on fresh diesel do our engineers leave. The vehicle returns to normal driving at once, and long-term damage is very uncommon when it has been caught soon. ## Wellesbourne, after your fuel drain: back on the road - Started on clean diesel, it needs nothing unusual of you. Simply drive normally. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop and ring us again. - Hold on to your paperwork. A hire company, a fleet manager or an insurer may ask what was carried out. - Next time, trust the pump's label rather than the colour of its handle. ## About Wellesbourne and where it is Wellesbourne is a village in Warwickshire, situated on the banks of the River Dene at an elevation of around 50 metres.
