Petrol in a diesel that hasn't been run is generally a drain plus a flush, done right where the car sits, and what you do in the next few minutes decides that more than anything else. Here's the sequence of things from now, wherever you are around Arney. ## Motor off: minute one with petrol in a diesel Go through these in order, before you do anything else. - Keys out of your ignition. Switching the ignition on can be enough to prime the system, and priming pulls petrol out of your tank towards the parts it damages. Leave the vehicle off completely. - No diesel on top. More fuel in removes none of the petrol — it just leaves you with more of the same blend. - Near passing traffic? Then the hazards come on before anything else, so your car is easy to see. - However short the distance, starting it to shift it is the thing to avoid. At a forecourt, push it away from the petrol pump by hand instead, then ask the attendants to lend a hand. - Which fuel, and roughly how much? The receipt answers that, and that is where our questions start. Don't bin it. Still on the move when you noticed? Come off the M77 at the next exit if that's where you are, over 50 miles from Arney, and stop somewhere safe rather than pressing on to the services. Then begin at step one. ## Has it run yet? The fork in each Arney fuel drain One answer is what everything after this point rests on. Engine never run at all? - Nowhere but your tank: that's where the petrol still is. - A drain and flush, on the spot, is normally all of it. - This is the best spot to be in, and the whole reason stage one counts. If your motor has been run, even briefly: - Petrol has been drawn from that tank, through the filter then into the fuel lines. - On a longer run it has got to the high-pressure pump as well as the injectors. - The farther it went, the larger the job — the fuel lines, your filter, and sometimes more besides. Petrol doesn't lubricate. Diesel does, oiling your pump and injectors as it passes through, which is why the line sits where it does. In the tank, sitting still, petrol does no harm. The components that move it are grinding the moment petrol is being pumped. ## Before you call about petrol in a diesel around Arney: what we need Whether the van circles or finds you depends on a little planning. - Where you are. A postcode starting BT92 2 is the best place to start. - The street or the car park. A road name helps — Crown Street, or wherever you have stopped. - Car parks are found most easily by what they serve: say the one at the local shops, and it's easy. - The car. Make, model, and that it is a diesel. - What was put in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Arney, so say which. - How long the nozzle was in, or the litres on your receipt — whichever tells us how much. - Has it run? If so, tell us how far it went, and the way it was driven. - Whose motor it is. Some hire and company agreements want the owner to approve this work, and that is quicker settled before our technicians arrive than after. Then call 0333 366 0103. If it can wait — the vehicle is at home with going nowhere — works as well. ## Waiting for a fuel drain around Arney: what to do Help, however well meant, is the thing that does the damage whilst you wait. So stick to these. - Where the vehicle has stopped decides where you wait. Exposed: away from it, clear of the traffic. Safe: with it. Either way, safety ahead of your car. - Not to roll it a couple of yards, not to check it is all right, not as a passer-by's kindness: nobody starts it. - None of it gets that petrol back out — not two-stroke oil, not injector cleaner, not something from your boot. So no additives. - Siphoning petrol into a can by the kerbside is dangerous — and it also leaves whatever fuel has already gone beyond the tank. Don't try a home-made drain. - Not for your radio, not for the windows: the ignition stays off. ## Van arrived? Your fuel drain, one stage at a time - Three queries. What was put in, how much, and if it has run. The replies shape the job, which is why our quote comes after them and not before. - Out of that tank comes the polluted mix: your tank is emptied. - Purging your lines follows, since a car that ran has petrol past that tank, in the fuel lines themselves. - Where the car has a usable filter, it's swapped; if not, cleared. - Clean diesel in, and the system primed. - The start. With fresh diesel in and the fuel system bled, it is started and checked to confirm it runs smoothly. Our technicians remain until it is running on fresh diesel. Permanent damage is very unusual when it has been noticed soon, so your car can go right back to normal use. ## Back on the road around Arney after your fuel drain - Nothing unusual is needed after a start with fresh diesel — ordinary driving is all. - Pull over and ring us back if anything looks wrong early on — a light on your dash, smoke from the exhaust, an idle that runs rough, or a throttle with a dead spot. - The work may matter later with a hire company, an insurer or a fleet manager. Hold on to the documents. - Next time, go by the petrol pump's label instead of the colour of its handle. ## About Arney itself Arney is a small locality in County Fermanagh, situated inland at an elevation of around 65 metres.
