Stop there. Hasn't been run? Then petrol in a diesel will usually be a straightforward drain-and-flush job wherever the car has stopped — and no other factor settles that as much as the next few minutes do. Here's the order of things from here, wherever you are around Mancot Royal. ## Petrol in a diesel, motor off — the first minute In this order, all before everything else: - Ignition off, keys out. Turned on, your ignition can prime the system — and priming is what moves petrol out of the tank towards the parts it harms. - Topping up with diesel seems like it thins the trouble. It does not: nothing gets out, and your tank simply carries more of the same. - Hazards on. If you're at all near moving traffic, make your car easy to see before you do anything else. - However short the distance, starting it to move it is the thing to avoid. On a forecourt, roll it away from the pump by hand instead, and ask the attendants to lend a hand. - Keep the receipt: the fuel and the rough amount are printed on it, and they are what our technicians ask about first. Still on the move when you realised? Come off the M56 at the next junction if that is where you are, under 5 miles from Mancot Royal, and pull over somewhere safe rather than pressing on to the services. Then begin at stage one. ## The fork in every Mancot Royal fuel drain: has it run yet? Everything after this stage rests on one answer. Not run, not even once: - Nowhere but your tank: that's where the petrol still is. - The work is a simple drain and a flush, normally done where the car is. - This, here, is the best spot to be in, and the reason step one counts. If it has been started, even for a moment: - Out of that tank, through the filter, into your lines: that's how far the petrol has travelled. - A bigger run takes it right through to your high-pressure pump and the injectors. - The job grows with the mileage — lines cleaned, filter seen to, sometimes more. The reason the line falls there: diesel protects the high-pressure fuel pump and the injectors as it flows through them, and petrol does not. In your tank, sitting still, petrol harms nothing. As soon as it's pumped, petrol starts grinding whatever moves it. ## Before you call about petrol in a diesel in Mancot Royal: what our technicians need A technician that circles against a van that finds you: a little preparation is the difference. - The best place to start is a postcode — one starting CH5 2 — for where you are. - Name the road — Hawarden Way or wherever you have pulled up — or the car park. - What a car park serves is the easiest way to find it, so say the landmark — like the one at Asda. - The vehicle. Make, model, and that it is a diesel. - Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has its own Mancot Royal page. - How long the nozzle was in, or the litres from your receipt — either tells us how much. - Whether it has run. And if it has, how far and how heavily. - The owner may have to authorise the work under some hire and company agreements — which is why it's quicker to settle whose car it is before we get there. Then call 0333 366 0103. If it can wait — the car is at home with going nowhere — does the trick too. ## Mancot Royal fuel drain on its way? While you wait The wait is where well-meant help does the harm. Stick to these. - Your safety comes before your car. Somewhere unsafe? Get clear of the traffic and wait away from it. Fine where it is? Stay with it. - Not to roll it a few yards, not to check it is all right, not as a passer-by's kindness: no one starts it. - Something from your boot, oil meant for two-strokes or injector cleaner: no additive removes the petrol. - Siphoning petrol into a can at the kerbside is risky — and it still leaves whatever fuel has already gone beyond your tank. Don't drain the car yourself. - Not for your radio, not for the windows: your ignition remains off. ## Step by step: your fuel drain when the van gets there - First, three questions: which fuel went in, the amount, and has it run? Those answers decide this job, and so our quote follows them. - Clearing it is how that mixture gets taken from your tank. - Flushing your lines follows, since a vehicle that ran has petrol past the tank, in the fuel lines themselves. - Then your filter: swapped where there is a serviceable one, cleared where there's not. - Priming follows once fresh diesel is in. - Our technicians start the car only after clean diesel has gone in and bled the fuel system, then confirm that it's running smoothly. Only once it's running on clean diesel do we head off. The car goes back to normal use right away, and long-term damage is very rare when it has been caught early. ## Once your fuel drain is done: driving around Mancot Royal a second time - Started on fresh 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 then ring us a second time. - Keep the paperwork. A hire company, a fleet manager or an insurer may ask what was carried out. - Read the label on the pump next time, not the colour of the handle. ## About Mancot Royal Mancot Royal is a small village in Flintshire, situated near the England-Wales border and close to the city of Chester.
