Pause there. Emptied then purged, right where it sits: that is normally all an unrun diesel with petrol in it needs. Whether it remains that simple rests on the minutes ahead far more than on anything else. What follows is the sequence from this point, anywhere around Ardglass you are. ## Petrol in a diesel? What to do in minute one First, these — following this order. - The ignition off, keys out. Switched on, the ignition can prime the system — and priming is what draws petrol out of your tank into the components it damages. - A bigger tank of the same mix is all adding diesel gives you, since it removes nothing. So no extra diesel. - Being seen comes before the rest beside moving traffic: switch the hazard lights on, and only then deal with anything else. - Off the petrol pump by hand. On a forecourt, get the attendants to help you roll the car away from the petrol pump. Don't crank it to move it, however short the distance. - Hold on to the receipt. It says which fuel went in and about how much, which is the first thing we will ask. On the M77, over 50 miles from Ardglass, 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 step one. ## Ardglass fuel drain: has the engine run yet, or not? From this point on, everything hinges on a single answer. Engine not run at all? - That petrol is still inside that tank and nowhere else. - Draining and flushing, on the spot, is usually the whole job. - This is the best position to be in, and the whole reason step one matters. If it has been started, even for a second: - From your tank, past the filter, into the fuel lines: that's how far that petrol has got. - The high-pressure fuel pump as well as the injectors see it too on a longer run. - Mileage is what turns it into a larger job: the lines flushed, a filter seen to, and at times more than that. The line falls there since diesel protects the high-pressure fuel pump and the injectors on its way through them — and petrol doesn't. A tank of petrol, left alone, hurts nothing. Petrol being pumped is grinding down the components that move the vehicle. ## Calling about petrol in a diesel from Ardglass: what to have ready Get ready a little, and the technician finds you rather than circling. - BT30 7 plus the rest of the postcode is the ideal way to begin telling us where you are. - A road name is a help: B7041, say, or whatever street you've stopped in. A car park does the trick too. - Name a car park by what it serves — the one at the local shops, for instance — and it's much quicker to find. - The make and model of the car, and the fact it's a diesel. - Say which was put in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Ardglass. - How long the nozzle was in, or the litres from the receipt — either tells us how much. - Whether it's run. And if it has, how far and how heavily. - Sort who owns your car before our engineers turn up: some hire and company agreements want the owner to authorise this work, and that is quicker beforehand. Next, 0333 366 0103. Not pressing, your car left at home with nowhere to be? Then will do as well. ## Ardglass fuel drain on its way? Whilst you wait Help, however well meant, is the thing that does the harm whilst you wait. So stick to these. - Safety before the car. If it has stopped somewhere dangerous, get yourself away from 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 vehicle a short way. - Additives stay in the boot. Injector cleaner and two-stroke oil take none of the petrol out once more. - No home-made clearing. Siphoning petrol into a can at the roadside is risky, and it leaves your fuel that has by now gone beyond that tank. - Even your radio or your windows are not worth switching the ignition on for. ## Step by step: your fuel drain when our van arrives - Our price comes after three queries, not before them — what got in, how much, and if it's run — since those answers shape the job. - Out of that tank comes the tainted blend: your tank is emptied. - If it ran, your lines are carrying petrol that has shifted beyond your tank — so they're cleaned. - Cleared, or swapped if the car has a usable one: your filter is sorted next. - Fresh diesel in, and the fuel system primed. - Starting it. After the fuel system is bled with new diesel, our engineers fire it up and confirm it runs properly. Till it runs on clean diesel, our engineers remain with it. Permanent damage is very unusual if it has been spotted early, so the vehicle can go right back to normal use. ## Ardglass, after your fuel drain: back on the road - Started on new diesel, it needs nothing special of you. Just drive normally. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop and call us once more. - The documents covers the query a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Next time, read the petrol pump. The label, not the colour of its handle. ## About Ardglass itself Ardglass is a small coastal locality in County Down, Northern Ireland, with a population of around 1175 people.
