Pause 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 these next few minutes do. Wherever you happen to be in Mumps, here is the order things go from here. ## Minute one: petrol in a diesel, motor off Work through the following first, in this order. - The ignition off, keys out. Turned on, the ignition can prime your system — and priming is what moves petrol out of your tank into the components it harms. - Do not top it up with diesel. Adding diesel removes nothing. You end up with a fuller tank of the same mixture. - Near passing traffic? Then your hazards come on before anything else, so the vehicle is simple to spot. - Off the petrol pump by hand. At a forecourt, get the staff to help you roll the vehicle away from the pump. Do not fire it up to move it, however short the way. - The first thing you will be asked is which fuel went in and about how much — and the receipt says both. Hold on to it. On the Broadway, under 3 miles from Mumps, the next exit is the spot to come off; anywhere, the first safe location to stop. Don't push on to the services. Then go back to stage one. ## Has it run yet? The fork in every Mumps fuel drain From this point on, everything comes down to a single answer. Engine not run at all? - Just your tank has petrol in it for now. - Where the vehicle sits is normally where the work is done: a drain, then a flush. - This is the best position to be in, and the whole reason stage one matters. Motor run, even briefly? - Some petrol has left that tank by now, gone through the filter, and reached the lines. - Run it farther and the petrol gets to the fuel injectors, having passed through the fuel pump first. - The job expands with the mileage — lines purged, filter dealt with, occasionally more. Why the line falls there: diesel lubricates your high-pressure pump as well as your injectors as it passes through them, and petrol does not. Nothing is harmed by petrol that is just waiting in a tank. Pump that petrol, though, and it grinds down the very parts that move it. ## Before you call about petrol in a diesel around Mumps: what our engineers need Get ready a little, and the technician finds you rather than circling. - OL1 3 plus the rest of the postcode makes the ideal way to begin telling us where you are. - A road name is a help: Bridgewater Street, say, or whatever street you've stopped in. A car park does the trick too. - What a car park serves is the quickest way to find it, so say the landmark — like the one outside Heron Foods. - Say what the car 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 Mumps. - About how much — in litres from your receipt, or by how long the nozzle was in. - Has it run? If so, tell us how far it got, and how it was driven. - Sort who has your car ahead of when our engineers arrive: some hire and company contracts want the owner to authorise the work, and doing it quicker beforehand. Phone 0333 366 0103 then. Writing to works too if it can wait, with the car parked at home, going nowhere. ## The wait for a Mumps fuel drain, and what to do in it In the wait, the harm comes from kindly meant help — which is why these count. - Stay with the car 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 few yards, not to check it is all right, not for a passer-by's favour: no one starts it. - Something from your boot, oil made for two-strokes or injector cleaner: no additive lifts the petrol. - No home-made emptying. Siphoning petrol into a can at the roadside is hazardous, and it leaves the fuel that has by now gone beyond that tank. - Even your radio or your windows are not worth turning the ignition on for. ## When the van gets there: the fuel drain, step by step - Our price comes after three questions, not before them — what got in, how much, and if it's run — because those replies set this job. - Emptying it is how the mixture gets taken from the tank. - If it ran, the lines are carrying petrol that has shifted beyond your tank — so they're rinsed. - Cleaned, or replaced if the car has a serviceable one: the filter is seen to next. - Bleeding your system follows after fresh diesel is in. - Our technicians fire it up only after fresh diesel has gone in and bled the system, then confirm that it is running smoothly. Your car has fresh diesel running through it before we leave. The vehicle goes back to normal driving right away, and long-term damage is very rare when it has been caught early. ## Back on the road in Mumps after your fuel drain - Nothing unusual is needed after a start with clean diesel — normal driving is all. - Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle means pull over and call us back. - The paperwork covers the question a rental company, fleet manager or insurer may ask: what work was carried out. Keep it. - The handle's colour isn't the guide to go by next time — the label on the petrol pump is. ## About Mumps itself Mumps is a suburban area in Greater Manchester, situated approximately 7.4 miles from Manchester city centre.
