Drained and rinsed, right where it is: that's generally all an unrun diesel with petrol in it needs. Whether it remains that simple rests on the minutes to come far more than on anything else. From here on, in order, for anywhere around Longford: ## Engine off: minute one with petrol in a diesel In this order, all before anything else: - Priming your fuel system pulls petrol from the tank towards the parts it harms, and turning your ignition on can be all it takes to do that. So the keys come out, and the ignition remains off completely. - A bigger tank of the same mix is all adding diesel leaves you, because it takes out nothing. So no more diesel. - Hazard lights on. If you are anywhere close to moving traffic, make the vehicle simple to see before you do anything else. - Off the petrol pump by hand. At a forecourt, get the attendants to help you push the car away from the petrol pump. Do not fire it up to shift it, however short the way. - The first question we will ask is which fuel you put in and roughly how much — and the till receipt shows both. Hold on to it. If you were still driving when you noticed, stop somewhere sensible instead of pushing on for the services — on the M6, under a mile from Longford, that means the next junction. Step one comes next. ## Has it run yet? The fork in every Longford fuel drain From this point on, everything hinges on a single answer. If it has never been started: - All the petrol sits in that tank, and only there. - Where your car sits is normally where the work happens: a drain, then a flush. - Being here is as good as it gets — which is the whole point of step one. If your engine has run, even for a moment: - From the tank, past the fuel filter, into the lines: that is how far the petrol has got. - Your high-pressure pump and the fuel injectors see it too on a longer run. - The job grows with the miles — lines cleaned, filter sorted, sometimes more. Petrol does not lubricate. Diesel does, oiling your pump and injectors as it flows through, which is why the line sits where it does. Nothing is harmed by petrol that's only resting in a tank. The parts that shift it are grinding the moment petrol is being pumped. ## Calling about petrol in a diesel from Longford: what to have prepared Get ready a little, and the technician finds you rather than circling. - CV6 6 plus the remainder of the postcode makes the ideal way to begin telling us where you are. - The street or the car park. A road name is a help — Hurst Road, or wherever you have pulled up. - What a car park serves is the easiest way to find it, and so say the landmark — such as the one at Tesco Extra. - Tell us what your vehicle is — make, model — and confirm it's diesel. - Tell us which went in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Longford. - How much. Litres from your receipt, or how long the nozzle was in. - Whether it's run. And if it has, how far plus how hard. - Settle who owns your car before our technicians arrive: some hire and company agreements want the owner to authorise the work, and doing it quicker beforehand. Next, 0333 366 0103. Not urgent, the vehicle parked at home with nowhere to be? Then will do too. ## The wait for a Longford fuel drain, and what to do in it The wait is where kindly meant help does the harm. Stick to these. - Stay with the vehicle if it's safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it. - Not to roll it a couple of yards, not to check it is all right, not as a passer-by's favour: no one starts it. - None of that gets the petrol back out — not two-stroke oil, not injector cleaner, not anything from the boot. So no additives. - A home-made drain misses your fuel that has already gone beyond that tank, and siphoning petrol by the road is hazardous besides. - Even your radio or the windows aren't worth turning your ignition on for. ## Van arrived? The fuel drain, one stage at a time - Fuel, volume, whether it has run: the answers set the job, and that's why we give a quote after them instead of before. - Draining it is how that mixture gets taken out of the tank. - The lines are purged. If it ran, that petrol has shifted beyond your tank, and the fuel lines are carrying it. - Then the filter: swapped where there's a usable one, cleared where there is not. - Your system is primed with fresh diesel. - First start on new diesel. When priming is complete, the motor is started and we check that it runs smoothly. Till it runs on fresh diesel, our technicians remain with it. The car returns to normal use straight away, and permanent damage is very rare if it has been spotted quickly. ## Back on the road around Longford after the fuel drain - Drive normally. There is nothing special to do once it has been started on fresh fuel. - Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or the throttle hesitating: pull over then ring us back. - The work may come up later with a hire firm, an insurer or a fleet manager. Hold on to your documents. - Next time, go by the pump's label instead of the colour of its handle. ## About Longford itself Longford is a suburban area in the West Midlands, situated on the River Sowe and close to the city of Coventry.
