Motor off. Leave it like that — no moment on, no moving it at all. Has not been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever the car has stopped — and nothing decides that more than these next few minutes do. Wherever you are around Addiewell, here is the order things go from here. ## Engine off: minute one with petrol in a diesel Before anything else, the following — following this order. - Ignition off, keys out. Turned on, your ignition can prime your system — and priming is what draws petrol out of the tank into the components it harms. - Topping up with diesel seems like it dilutes the issue. It does not: nothing comes out, and the tank just carries more of the same. - Make the vehicle simple to see before anything else — hazards on — if there's moving traffic anywhere near you. - However short the way, starting it to move it is the mistake. At a forecourt, roll it clear of the petrol pump by hand instead, then ask the staff to help. - The first thing you will be asked is which fuel you put in and about how much — and the till receipt shows both. Keep it. Realised on the move? Get off at the next junction if you're on the M8, under 3 miles from Addiewell, and stop somewhere sensible — not at the services farther on. Stage one starts after that. ## Addiewell fuel drain: has your engine run yet, or not? Everything after this stage rests on one answer. If your engine has not run at all: - The petrol is still inside your tank and nowhere else. - Normally it's emptied and purged just where the car stands. - This is the best case — which is the whole point of step one. If your engine has been run, even for a moment: - From your tank, through the fuel filter, into your lines: that's how far that petrol has got. - On a bigger run it has got to your high-pressure pump and your injectors. - The job expands with the mileage — lines rinsed, filter seen to, sometimes more. The line falls there since diesel lubricates your high-pressure pump and your injectors on its way through them — and petrol doesn't. In your tank, left alone, petrol harms nothing. The parts that move it are grinding the moment petrol is being pumped. ## Before you call about petrol in a diesel around Addiewell: what our technicians need A little preparation is the difference between a technician that finds you and a van that circles. - The ideal place to start is a postcode — one beginning EH55 8 — for where you have stopped. - Wherever you have parked, the road's name helps — whether that's Blackburn Road or somewhere else — and so does the name of a car park. - Or the landmark. A car park is quicker to find by what it serves, such as the one at Scotmid. - The make and model of your car, and the fact it's a diesel. - Which was put in counts: AdBlue is a separate job from petrol, plus Addiewell has a page just for that. So tell us. - About how much — in litres from the receipt, or by how long the nozzle stayed in. - Has it run? If so, say how far it went, and the way it was driven. - Sort who has your car before we turn up: some hire or company contracts want the owner to approve the work, and that is quicker beforehand. Then ring 0333 366 0103. If it can wait — the car is at home and going nowhere — does the trick too. ## Waiting for a fuel drain around Addiewell: what to do Stick to these: well-meant help causes the damage during the wait. - Safety before the car. If it has stopped somewhere unsafe, get yourself away from the traffic then wait away from it. If it is safe where it is, wait with it. - Nobody starts it. Not a passer-by being kind, not to check it is all right, not to roll the vehicle a couple of yards. - None of that takes that petrol back out — not two-stroke oil, not injector cleaner, not anything from your boot. So no additives. - No DIY draining. Siphoning petrol into a can by the kerbside is risky, and it leaves the fuel that has already gone beyond your tank. - Even your radio or the windows are not worth switching the ignition on for. ## When the van arrives: your fuel drain, step by step - First, three questions: which fuel got in, the quantity, and has it run? Those answers decide the job, so our price follows them. - Out of your tank comes the tainted mixture: that tank is drained. - Petrol that has shifted beyond the tank travels in the lines if it ran, and the fuel lines are cleaned to shift it. - Where your car has a usable filter, it's changed; otherwise, cleared. - Your system is primed on fresh diesel. - We fire it up only after fresh diesel has gone in and bled your system, then confirm that it's running correctly. The vehicle has clean diesel running through it before we head off. If it has been noticed early, permanent damage is very uncommon, and your car goes back to normal driving right away. ## Back on the road in Addiewell after the fuel drain - Started on clean diesel, it asks nothing unusual of you. Simply drive normally. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a flat throttle is your cue to stop then ring us once more. - The work may matter later with a hire company, an insurer or a fleet manager. Hold on to the documents. - Next time, trust the petrol pump's label instead of the colour of its handle. ## About Addiewell, for a moment Addiewell is a village situated on the riverside in West Lothian, with a mix of detached housing and a population of around 725 residents.
