Engine off. Leave the vehicle that way — no moment on, no shifting it anywhere. Hasn't been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever your vehicle has stopped — and nothing settles that as much as these next few minutes do. From now on, step by step, wherever you are in Nailbridge: ## Minute one: petrol in a diesel, engine off Do these before anything else, in this sequence. - The ignition off, keys out. Switched on, your ignition can prime your system — and priming is what moves petrol out of your tank into the components it harms. - No diesel on top. More fuel in removes none of the petrol — it only leaves you with extra of the same blend. - Visibility comes before the rest beside moving traffic: switch the hazards on, and only then deal with anything else. - The staff will normally help you push it clear of the pump. Let them, then roll it by hand — never under the engine, even for a couple of yards. - Which fuel, and roughly how much? Your receipt replies both, and that's where our questions start. Do not throw it away. Still on the move when you realised? Come off the M50 at the next exit if that's where you are, under 10 miles from Nailbridge, and pull over somewhere safe and not pressing on to the services. Then start at step one. ## Has it run yet? The fork in every Nailbridge fuel drain Everything after this stage depends on one answer. Not run, not even briefly: - All the petrol sits in the tank, and just there. - Draining and flushing, on the spot, is normally the whole job. - Step one matters for precisely this reason: it is the best place to be in. Run at all, even for a second: - Some petrol has left the tank by now, gone through the filter, and got into your lines. - On a bigger run it has got to the high-pressure fuel pump and the injectors. - Distance is what turns it into a bigger job: flushed lines, a filter seen to, and at times further work. Why the line falls there: diesel lubricates the high-pressure fuel pump as well as the injectors as it passes through them, and petrol does not. Nothing is damaged by petrol that's only waiting in a tank. Move that petrol, though, and it grinds down the very parts that move it. ## What to have prepared when you call about petrol in a diesel from Nailbridge Prepare a little, and the van finds you instead of circling. - Your location: a postcode starting GL17 9 serves best. - A road name is a help: Morse Road, say, or whichever street you have stopped in. A car park works too. - Describe a car park by what it serves — the one outside Lidl, for instance — and it is far quicker to find. - The make and model of the car, and the fact it's a diesel. - Petrol or AdBlue? Say which. They are different jobs, and AdBlue has its own Nailbridge page. - The quantity: your receipt's litres, or else how long you held the nozzle in. - Has it run? If so, tell us how far it went, and how it was driven. - Settle who owns the vehicle ahead of when our engineers turn up: some hire or company contracts want the owner to authorise this work, and doing it faster first. Then phone 0333 366 0103. If it can wait — your car is at home and going nowhere — does the trick as well. ## Waiting for a fuel drain around Nailbridge: what to do The wait is where kindly meant help does the damage. Stick to these. - Your safety comes before the car. Somewhere unsafe? Get away from the traffic then wait away from it. Fine where it is? Stay with it. - No one — however helpful — starts it, whether to see if it runs or to move the vehicle a short way. - None of that takes the petrol back out — not two-stroke oil, not injector cleaner, not something from the boot. So no additives. - Siphoning petrol into a can by the roadside is dangerous — and it still leaves whatever fuel has already gone beyond that tank. Don't drain it yourself. - Not for the radio, not for your windows: your ignition remains off. ## When our van arrives: your fuel drain, step by step - Fuel, quantity, whether it has run: those replies set this job, and that's why we give a price after them instead of before. - Out of the tank comes the tainted mix: that tank is emptied. - Petrol that has shifted beyond the tank travels in the lines once it ran, and your lines are purged to clear it. - Where your car has a workable filter, it is replaced; otherwise, cleared. - Fresh diesel in, and the system primed. - Starting the car. Once your system is bled with fresh diesel, our engineers fire it up and confirm it runs smoothly. Only once it is running on fresh diesel do our engineers go. When it has been noticed quickly, long-term damage is very rare, and the vehicle returns to normal use at once. ## After your fuel drain: back on the road in Nailbridge - Started on clean diesel, it needs nothing special of you. Simply drive normally. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a hesitant throttle is your cue to stop and call us once more. - The work may come up later with a hire company, an insurer or a fleet manager. Keep the documents. - Next time, check the pump. The label, not the colour of its handle. ## About Nailbridge, for a moment Nailbridge is a small suburban area in Gloucestershire, situated on the riverside at an elevation of 179 metres.
