Stop; leave the vehicle off. The coming few minutes settle it far more than anything else: petrol in a diesel still unrun generally amounts to emptying then purging, on the spot. Anywhere you are around Stewartstown, here is how things go from now. ## Petrol in a diesel? What to do in minute one Go through the following in order, first. - The ignition off, keys out. Turned on, the ignition can prime your system — and priming is what moves petrol out of the tank into the parts it harms. - Topping up with diesel seems like it dilutes the issue. It doesn't: nothing gets out, and the tank simply carries more of the same. - Near passing traffic? Then your hazards go on before anything else, and so your car is easy to see. - By hand, never under the motor: that's how it comes off the petrol pump. Ask the forecourt attendants to help you roll, however short the distance. - The first question we will ask is which fuel you put in and roughly how much — and the till receipt says both. Hold on to it. On the M77, over 50 miles from Stewartstown, the next junction is the location to come off; elsewhere, the first sensible spot to stop. Do not push on to the services. Then go back to step one. ## Stewartstown fuel drain: has the engine run yet, or not? What comes after this rests on one answer, and only one. Not run, not even briefly: - That petrol is still in the tank and nowhere else. - Draining and flushing, on the spot, is normally all of it. - This, here, is the best position to be in, and the reason stage one matters. If it's been started, even for a moment: - The lines and the fuel filter now hold petrol pulled from your tank. - On a bigger run it has got to the high-pressure fuel pump as well as the fuel injectors. - The job grows with the distance — lines rinsed, filter seen to, sometimes more. Petrol does not lubricate. Diesel does, oiling your pump and injectors as it passes through, which is why the line falls where it does. Nothing is damaged by petrol that is just resting in a tank. Move that petrol, though, and it wears the very parts that move it. ## Calling about petrol in a diesel from Stewartstown: what to have prepared Whether the technician circles or finds you comes down to a little preparation. - Your whereabouts: a postcode beginning BT71 5 serves best. - Wherever you have parked, the road's name is useful — whether that is Chalet Road or somewhere else — and so does the name of a car park. - What a car park serves is the quickest way to find it, so mention the landmark — such as the one at the local shops. - Say what your vehicle is — make, model — and confirm it's diesel. - Which went in matters: AdBlue is a separate job from petrol, plus Stewartstown has a page for it. So tell us. - How long the nozzle was in, or the litres on your receipt — whichever tells us how much. - The mileage it did, and how hard, if it ran at all. - Sort who owns your car ahead of when our technicians arrive: some hire and company agreements want the owner to approve the work, and that is faster first. Then phone 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — does the trick as well. ## While you wait for a fuel drain in Stewartstown Stick to these: well-intended help does the harm during the wait. - Wait with the car if it is safe where it is — but if it has stopped somewhere dangerous, you come first: away from the traffic, waiting apart from it. - Not to roll it a few yards, not to check it is all right, not as a passer-by's favour: no one starts it. - None of it takes the petrol back out — not two-stroke oil, not injector cleaner, not something from the boot. So no additives. - No home-made clearing. Siphoning petrol into a can at the kerbside is hazardous, and it leaves your fuel that has already gone beyond the tank. - Not for your radio, not for the windows: the ignition stays off. ## Van arrived? The fuel drain, one stage at a time - Three questions. What got in, how much, and whether it has run. The replies decide this job, which is why our price comes after them but not before. - That tank is cleared. The polluted mix comes from the tank. - Petrol that has shifted beyond the tank sits in the fuel lines if it ran, and the fuel lines are purged to shift it. - Where the vehicle has a usable filter, it is replaced; if not, cleared. - Clean diesel in, and the fuel system primed. - Starting up. Once the fuel system is bled with clean diesel, our engineers start the car and check it runs properly. Our technicians wait until it's running on fresh diesel. Lasting damage is very unusual when it has been caught early, so the car can go right back to normal use. ## Back on the road around Stewartstown after the fuel drain - Nothing unusual is needed after a start with fresh diesel — normal driving is all. - Watch the first miles. A warning light, smoke, a rough idle or a flat spot under your throttle tells you to pull over and call us back. - An insurer, a fleet manager or a hire firm may ask what was carried out, and so hold on to the documents. - Check the label on the petrol pump next time, not the colour of its handle. ## About Stewartstown and where it is Stewartstown is a small locality in County Tyrone, situated inland at an elevation of 72 metres, and is located near the towns of Donaghey, Coalisland, and Tullyhogue.
