Here Is What Happens Whatever you do, never switch your engine on, even for a moment, to shift the vehicle. Stop; leave it off. Cleared then rinsed, just where it sits: that is usually all an unrun diesel with petrol in it takes. Whether it stays that simple depends on the minutes ahead more than on everything else. Anywhere you happen to be in Dunnamore, here is the order things go from here. ## Motor off: minute one with petrol in a diesel Before anything else, these — in this order. - The keys out of the ignition. Turning the ignition on can be all it takes to prime the system, while priming pulls petrol out of the tank towards the components it harms. Leave it off altogether. - Topping up with diesel sounds like it dilutes the trouble. It doesn't: nothing gets out, and your tank simply holds more of the same. - Visibility comes first near moving traffic: put the hazards on, and only then think about everything else. - Off the pump by hand. At a forecourt, ask the attendants to help you push the car away from the petrol pump. Do not fire it up to move it, however short the distance. - Keep the receipt. It shows which fuel got in plus about how much, which is the first thing we'll ask. Noticed on the move? Get off at the next exit if you're on the M77, over 50 miles from Dunnamore, and pull over somewhere sensible — not at the services farther on. Step one starts after that. ## The fork in each Dunnamore fuel drain: has it run yet? Everything after this point rests on one answer. If it has not once been started: - Just that tank has petrol in it for now. - The job is a simple drain and a flush, usually done where the car stands. - Stage one counts for exactly this reason: it's the best place to be in. If your engine has run, even briefly: - Some petrol has left your tank by now, gone through your filter, and got into your lines. - The high-pressure pump and the fuel injectors get it on a longer run. - Flushing your lines, the fuel filter dealt with, occasionally more: the job grows as the miles does. Petrol does not lubricate. Diesel does, oiling your pump and injectors as it passes through, which is why the line falls where it does. In that tank, sitting still, petrol does no harm. The parts that move it are grinding the moment petrol is being pumped. ## Before you call about petrol in a diesel around Dunnamore: what we need Whether the technician goes round or finds you comes down to a little planning. - The ideal place to start is a postcode — one starting BT80 9 — for where you have stopped. - A road name is a help: Wallace Cottages, say, or whatever street you have stopped in. A car park does the trick too. - Or the landmark. A car park is quicker to find by what it serves, like the one at the local shops. - The make and model of your car, and the fact it is a diesel. - Which got in counts: AdBlue is a separate job from petrol, and Dunnamore has a page just for that. So tell us. - How much. Litres from the receipt, or how long the nozzle was in. - Whether it's run. Then if it has, how far and how hard. - Hire or company car? Some agreements want the owner's go-ahead for the work, and sorting it before we get there is faster than afterwards. Call 0333 366 0103 next. Writing to works too if it can wait, with the car parked at home, going nowhere. ## Dunnamore fuel drain on its way? Whilst you wait Stick to these: kindly meant help causes the harm during the wait. - Your safety comes before the vehicle. Somewhere dangerous? Get clear of the traffic then wait away from it. Fine where it is? Stay with it. - Nobody starts it. Not a passer-by being helpful, not to check it is all right, not to roll it a couple of yards. - Anything from your boot, oil made for two-strokes or injector cleaner: no additive lifts that petrol. - No home-made clearing. Siphoning petrol into a can by the roadside is hazardous, and it leaves the fuel that has already gone beyond that tank. - The ignition stays off. Even for the radio or your windows. ## When our van arrives: the fuel drain, step by step - First, three queries: which fuel went in, the quantity, and has it run? Those answers set the job, so the quote follows them. - Your tank is emptied. The polluted blend comes out of the tank. - If it ran, the fuel lines are carrying petrol that has moved beyond your tank — so they're purged. - Cleared, or replaced if your car has a serviceable one: the filter is dealt with next. - Clean diesel in, and the system primed. - The first start on new diesel. Once priming is done, your engine is fired up and our technicians confirm that it runs smoothly. Until it runs on new diesel, we stay with it. Long-term damage is very uncommon when it has been noticed early, so your car can go straight back to normal driving. ## Dunnamore, after the fuel drain: back on the road - Started on clean diesel, it needs nothing unusual of you. Just drive normally. - Keep an eye on the first miles. A warning light, smoke, a rough idle or a flat spot under your throttle means pull over and ring us back. - Hold on to your documents. A hire firm, a fleet manager or an insurer may ask what was done. - Read the label on the petrol pump next time, not the colour of its handle. ## About Dunnamore, for a moment Dunnamore is a rural locality in County Tyrone, situated inland at an elevation of 162 metres.
