Stop; leave the car off. Drained and flushed, just where it is: that is normally all an unrun diesel with petrol in it takes. Whether it stays that straightforward rests on the minutes to come more than on anything else. From here on, in order, wherever you are in North Lancing: ## Petrol in a diesel, motor off — the first minute In this order, and before everything else: - The keys out of the ignition. Turning the ignition on can be all it takes to prime the fuel system, and priming pulls petrol out of the tank toward the parts it damages. Leave the vehicle off altogether. - Do not top it up with diesel. Adding diesel takes out nothing. You are left with a fuller tank of the same mixture. - Make your car easy to see before anything else — hazard lights on — if there is moving traffic anywhere close to you. - The staff will normally help you roll it away from the pump. Let them, then move it by hand — never on the engine, even for a few yards. - Which fuel, and roughly how much? Your receipt replies both, and that's where our questions start. Don't throw it away. If you were still driving when you realised, pull over somewhere safe instead of pushing on for the services — on the M23, under 25 miles from North Lancing, that means the next junction. Step one comes next. ## Has it run yet? The fork in every North Lancing fuel drain Everything after this point depends on one answer. If the motor has not run at all: - The petrol is still inside the tank and nowhere else. - The job is a simple drain and a flush, normally done where the vehicle stands. - No spot is better, and it's why the first stage counts so much. If it has been started, even for a second: - The lines and the fuel filter already carry petrol drawn from your tank. - Your high-pressure pump as well as your injectors see it too on a bigger run. - The job grows with the mileage — lines cleaned, filter seen to, occasionally more. Why the line falls there: diesel protects your high-pressure pump as well as the injectors as it flows through them, and petrol does not. Petrol resting in a tank harms nothing. Petrol being pumped is grinding down the parts that shift the car. ## North Lancing, petrol in a diesel: have these prepared before you call Whether the van circles or finds you comes down to a little preparation. - Your location: a postcode starting BN15 0 serves best. - The road or the car park. A road name is a help — Mill Road, or wherever you have stopped. - Car parks are located more easily by what they serve: say the one at Co-op Food, and it is easy. - Say what your vehicle is — make, model — and confirm it is diesel. - Tell us which was put in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for North Lancing. - Roughly how much — in litres from the receipt, or by how long the nozzle stayed in. - Has it run? If so, say how far it got, and the way it was driven. - Sort who has your car before our engineers turn up: some hire or company agreements 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 with going nowhere — does the trick as well. ## Waiting for a fuel drain in North Lancing: what to do Help, however well meant, is the thing that does the damage while you wait. So stick to these. - Where the car has stopped settles where you wait. Exposed: away from it, clear of the traffic. Safe: with it. Either way, safety ahead of the vehicle. - A kind passer-by does not crank it. Nor does anyone wanting to check it still does the trick, or rolling it a couple of yards. - Anything from your boot, oil made for two-strokes or injector cleaner: no additive removes that petrol. - No DIY draining. Siphoning petrol into a can at the kerbside is risky, and it leaves your fuel that has by now gone beyond that tank. - Not for your radio, not for your windows: the ignition stays off. ## Van arrived? The fuel drain, one stage at a time - The price comes after three queries, not before them — what got in, how much, and if it's run — since the answers shape this job. - Out of that tank comes the contaminated blend: the tank is emptied. - Rinsing the lines comes next, because a vehicle that ran has petrol past that tank, inside the lines themselves. - Then the filter: replaced where there is a workable one, cleared where there is not. - Fresh diesel in, and the fuel system primed. - We start the engine only after fresh diesel has gone in and primed your system, then check that it is running properly. Our engineers wait until it's running on clean diesel. When it has been caught early, permanent damage is very unusual, and your car returns to normal use right away. ## Once the fuel drain is done: driving in North Lancing once more - Nothing special is needed after a start with fresh diesel — normal driving is all. - Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle tells you to pull over and ring us back. - Hold on to your documents. A hire company, a fleet manager or an insurer may ask what was done. - The handle's colour isn't the thing to go by next time — the label on the petrol pump is. ## About North Lancing and where it is North Lancing is a suburban area situated on the coast of West Sussex, with a mix of semi-detached housing and other residential properties.
