Motor off. Leave it that way — no moment on, no moving it anywhere. Petrol in a diesel that hasn't been run is usually a simple drain plus a flush, done where your vehicle sits, and what happens in the coming few minutes determines that far more than anything else. Below is the sequence from this point, anywhere in Forkill you are. ## Petrol in a diesel? What to do in minute one Go through these in sequence, before you do anything else. - The ignition off, keys out. Switched on, the ignition can prime your system — and priming is what draws petrol out of your tank towards the components it harms. - Do not top it up with diesel. Adding diesel takes out nothing. You end up with a bigger tank of the same mix. - Hazards on. If you are anywhere near moving traffic, make the vehicle easy to see before you do anything else. - The staff will normally help you roll it away from the petrol pump. Let them, then move it by hand — never on the engine, even for a few yards. - Keep your receipt. It shows which fuel was put in and roughly how much, which is the first thing we'll ask. Realised on the move? Get off at the next junction if you're on the M77, over 50 miles from Forkill, and stop somewhere sensible — not at the services farther on. Step one starts after that. ## Every Forkill fuel drain starts here: has your motor run? From this stage on, everything hinges on a single answer. If the engine hasn't run at all: - Just the tank has petrol in it for now. - Where the car sits is normally where this work happens: a drain, then a flush. - Being here is as good as it gets — which is the entire point of step one. If your motor has been run, even for a moment: - Some petrol has left that tank by now, passed through the fuel filter, and reached the lines. - On a bigger run it has got to your high-pressure pump as well as your injectors. - The job expands with the miles — lines rinsed, filter seen to, sometimes more. That line falls there because diesel lubricates your high-pressure pump and the fuel injectors on its way through them — and petrol does not. Petrol resting in a tank harms nothing. Petrol being pumped is grinding down the parts that move it. ## Calling about petrol in a diesel from Forkill: what to have prepared A technician that circles versus a technician that finds you: a little preparation is what separates them. - Where you are. A postcode beginning BT35 9 is the ideal start. - Give the street — High Row or wherever you have pulled up — or the car park. - What a car park serves is the easiest way to find it, so mention the landmark — such as the one at the local shops. - That it's a diesel, along with the make and model of your car. - Petrol or AdBlue? Say which. They are different jobs, and AdBlue has a separate Forkill page. - How much. Litres from the receipt, or how long the nozzle was in the filler. - Whether it has run. And if it has, how far and how hard. - The owner may have to approve this work under some hire and company agreements — so it is faster to settle whose vehicle it is before we get there. Ring 0333 366 0103 once you've got that together — or, if the vehicle is at home, going nowhere, use . ## Whilst you wait for a fuel drain around Forkill During the wait, the damage comes from well-meant help — which is why these count. - Your safety comes before the vehicle. Somewhere unsafe? Get clear of the traffic then wait away from it. Fine where it is? Wait with it. - Nobody — however helpful — starts it, whether to see if it runs or to shift the car a short way. - Something from the boot, oil made for two-strokes or injector cleaner: no additive lifts the petrol. - Draining it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and the fuel beyond your tank remains put anyway. - Even the radio or your windows are not worth switching your ignition on for. ## Van arrived? The fuel drain, one stage at a time - The quote comes after three queries, not before them — what got in, how much, and if it's run — because the answers shape the job. - Your tank is emptied. The contaminated blend comes out of that tank. - The fuel lines are flushed. If it ran, the petrol has shifted beyond your tank, and your lines are holding it. - Cleared, or replaced if your car has a usable one: the fuel filter is dealt with next. - Clean diesel in, and your system primed. - Our engineers start the car only after clean diesel has gone in and primed the fuel system, then confirm that it's running properly. Only when it is running on new diesel do our technicians go. Lasting damage is very uncommon if it has been caught soon, so your car can go straight back to normal driving. ## Forkill, after your fuel drain: back on the road - Drive normally. There is nothing special to do once it has been started on fresh fuel. - Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or the throttle stumbling: pull over and call us back. - An insurer, a fleet manager or a hire company may ask what was done, and so keep the paperwork. - Next time, go by the pump's label instead of the colour of its handle. ## About Forkill, briefly Forkill is a small locality in County Armagh, situated inland at an elevation of 67 metres, approximately 7.6 miles from Newry.
