Stop; leave the vehicle off. Emptied then rinsed, just where it sits: that's generally all an unrun diesel with petrol in it takes. Whether it remains that simple depends on the minutes ahead far more than on anything else. From here on, step by step, for anywhere in Dunseverick: ## Engine off: minute one with petrol in a diesel Work through these in order, first. - The keys out of your ignition. Turning your ignition on can be enough to prime the fuel system, while priming draws petrol out of the tank toward the components it damages. Keep the car off altogether. - Topping up with diesel sounds like it dilutes the trouble. It does not: nothing comes out, and that tank just carries more of the same. - Close to moving traffic? Then the hazards go on before anything else, and so your car is simple to spot. - Off the petrol pump by hand. At a forecourt, ask the staff to help you push it clear of the pump. Do not start it to move it, however short the distance. - The first thing you will be asked is which fuel went in and about how much — and your receipt says both. Hold on to it. On the M77, over 50 miles from Dunseverick, the next junction is the spot to leave the vehicle; elsewhere, the first sensible place to stop. Do not push on to the services. Then go back to stage one. ## The fork in every Dunseverick fuel drain: has it run yet? From this point on, everything hinges on a single answer. Not run, not even briefly: - The petrol is still inside the tank and nowhere else. - The work is a drain and a flush, usually done where your car stands. - This is the best position to be in, and the whole reason step one matters. Motor run, however briefly? - The fuel lines and your filter now carry petrol drawn from your tank. - Run it farther and that petrol reaches the fuel injectors, having passed through the fuel pump first. - The job grows with the miles — lines purged, filter dealt with, sometimes more. The reason the line falls there: diesel lubricates the high-pressure fuel pump and the injectors as it passes through them, and petrol doesn't. Nothing is damaged by petrol that's just resting in a tank. As soon as it's pumped, petrol begins wearing whatever moves it. ## Dunseverick, petrol in a diesel: have these ready before you call A van that circles against a van that finds you: a little preparation is the difference. - The best place to start is a postcode — one beginning BT57 8 — for where you are. - The road or the car park. A road name is a help — Frederick Crescent, or wherever you have stopped. - What a car park serves is the easiest way to find it, so say the landmark — like the one outside the local shops. - That it's a diesel, plus the make and model of your car. - Which went in counts: AdBlue is a separate job from petrol, and Dunseverick has a page for it. So say. - Roughly how much — in litres from the receipt, or by how long the nozzle stayed in. - If it has run, how far plus how heavily — as well as if it has run at all. - Whose car it is. Some hire or company contracts want the owner to authorise the work, and that's quicker settled before our technicians arrive than after. Ring 0333 366 0103 once you've got that ready — or, if your car is at home, going nowhere, use . ## While you wait for a fuel drain around Dunseverick Hold to these: well-intended help does the damage during the wait. - Safety before your car. If it has stopped somewhere dangerous, get yourself clear of the traffic and wait away from it. If it is safe where it stands, stay with it. - No one — however kind — starts it, whether to see if it runs or to move the car a short way. - Additives stay in your boot. Injector cleaner and two-stroke oil draw none of that petrol out once more. - A home-made drain leaves the fuel that has already gone beyond your tank, and siphoning petrol by the road is hazardous too. - Keep your ignition off — the windows and your radio included. ## The fuel drain, step by step, once our van arrives - Fuel, amount, whether it has run: those answers set this job, and that's why you get a price after them instead of before. - Then your tank is drained, so the contaminated fuel is taken out. - The fuel lines are rinsed. If it ran, the petrol has shifted beyond your tank, and the fuel lines are carrying it. - Then the fuel filter: swapped where there is a usable one, cleared where there is not. - Bleeding the system comes after fresh diesel is in. - We start the engine only after clean diesel has gone in and primed the system, then make sure that it's running correctly. Until it runs on clean diesel, our technicians stay with it. It's very unusual for a vehicle caught quickly to be left with lasting damage, and normal use starts again straight away. ## After your fuel drain: back on the road around Dunseverick - After it has been started on clean fuel, there is nothing special to do: drive normally. - Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or the throttle hesitating: pull over and ring us back. - Keep the documents. A hire firm, a fleet manager or an insurer may ask what was done. - Next time, check the pump. The label, not the colour of its handle. ## About Dunseverick and where it is Dunseverick is a small coastal locality in County Antrim, situated near the villages of Bushmills and Portballintrae.
