Here Is What Happens Not for a second, and not to move it: the engine stays off. Pause there. Petrol in a diesel that hasn't been run is generally a simple drain and a flush, done where the car sits, and what happens in the coming few minutes decides that more than anything else. Here's the sequence of things from now, wherever you are around Shalbourne. ## Minute one: petrol in a diesel, engine off Go through these in order, before you do anything else. - Pull the keys out. Even the ignition on its own can prime the system, drawing petrol out of the tank to precisely the components it damages, so keep the vehicle alone completely. - A fuller tank of the same mixture is all topping up leaves you, since it removes nothing. So no extra diesel. - Being seen comes first near moving traffic: switch your hazards on, and only then think about anything else. - Off the pump by hand. At a forecourt, ask the staff to help you roll the car clear of the petrol pump. Don't start the car to shift it, however short the distance. - Hold on to the receipt: the grade and roughly how much are written on it, and they are what we ask about first. Still on the move when you noticed? Come off the M4 at the next junction if that is where you are, under 10 miles from Shalbourne, and pull over somewhere safe instead of pushing on to the services. Then start at step one. ## Has it run yet? The fork in each Shalbourne fuel drain Everything after this stage depends on one answer. If it has never been started: - Nowhere but your tank: that's where that petrol still is. - The work is a simple drain and a flush, usually done where the vehicle is. - No spot is better, and it is why the first step matters so much. If it has been started, even for a second: - Petrol has been drawn from your tank, past the fuel filter and into your lines. - On a bigger run it has got to the high-pressure pump and the fuel injectors. - Lines flushed, the fuel filter dealt with, occasionally more: the job expands as the distance does. That line falls there because diesel protects the high-pressure pump and the fuel injectors on its way through them — and petrol doesn't. A tank of petrol, left still, damages nothing. Petrol being pumped is grinding down the parts that shift the car. ## Before you call about petrol in a diesel in Shalbourne: what our engineers need A little planning is the difference between a van that finds you and a technician that goes round. - SN8 3 and the rest of the postcode is the best way to begin telling us where you are. - The road or the car park. A road name helps — Kingston Road, or wherever you have stopped. - Describe a car park by what it serves — the one at Tesco, for instance — and it's much easier to find. - Make and model of your car, and the fact it is a diesel. - Which got in matters: AdBlue is a separate job from petrol, plus Shalbourne has a page for it. So say. - Roughly how much — in litres from your receipt, or by how long the nozzle stayed in. - If it has run, how far and how hard — and whether it's run at all. - The owner may have to authorise this work under some hire and company agreements — so it is quicker to settle whose car it is before our technicians arrive. Next, 0333 366 0103. Not time-critical, the vehicle parked at home with nowhere to be? Then will do as well. ## Shalbourne fuel drain on its way? Whilst you wait Help, however well meant, is the thing that does the harm whilst you wait. So hold to these. - Safety before the vehicle. If it has stopped somewhere dangerous, get yourself clear of the traffic then wait away from it. If it's safe where it is, stay with it. - Nobody — however kind — starts it, whether to see if it runs or to move the vehicle a short way. - Additives stay in your boot. Injector cleaner and two-stroke oil draw none of the petrol out a second time. - Draining it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond that tank remains put all the same. - Leave your ignition off — your windows and the radio too. ## The fuel drain, step by step, once the van arrives - Three questions. What got in, how much, and if it's run. The replies set the job, which is why the price comes after them but not before. - Out of the tank comes the contaminated mixture: the tank is cleared. - Petrol that has moved beyond that tank sits in the fuel lines once it ran, and the lines are rinsed to shift it. - Where your car has a usable filter, it's replaced; if not, cleared. - The fuel system is primed on fresh diesel. - The first start on fresh diesel. Once priming is complete, the engine is started and our technicians confirm that it runs properly. Until it runs on clean diesel, we stay with it. It is very unusual for a vehicle noticed soon to be left with permanent damage, and normal driving resumes straight away. ## After the fuel drain: back on the road around Shalbourne - Started on new diesel, it needs nothing unusual of you. Just drive normally. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your cue to stop and ring us once more. - An insurer, a fleet manager or a hire firm may ask what was done, so hold on to your paperwork. - Next time, go by the petrol pump's label instead of the colour of its handle. ## About Shalbourne itself Shalbourne is a village in Wiltshire, situated on the banks of the River Shalbourne, with a mix of old and new buildings, including many detached houses.
