Stop there. Hasn't been run? Then petrol in a diesel will usually be a simple drain-and-flush job wherever your vehicle has stopped — and no other factor settles that more than these next few minutes do. Anywhere you are around Kingswear, this is the order things go from here. ## Minute one: petrol in a diesel, motor off Go through the following in sequence, before you do anything else. - Priming your fuel system draws petrol from your tank towards the components it harms, and switching the ignition on can be all it takes to do that. So the keys get taken out, and your ignition remains off altogether. - Don't top it up with diesel. Adding diesel removes nothing. You end up with a fuller tank of the same mixture. - Near passing traffic? Then your hazards go on before everything else, and so the vehicle is simple to spot. - The attendants will normally help you roll it away from the petrol pump. Let them, and roll it by hand — never on your engine, even for a few yards. - The first question you will be asked is which fuel went in and roughly how much — and the receipt says both. Keep it. On the M5, under 25 miles from Kingswear, the next exit is the spot to come off; anywhere, the first safe spot to stop. Do not press on to the services. Then go back to stage one. ## The fork in every Kingswear fuel drain: has it run yet? One answer is what everything after this stage rests on. If it has not once been started: - Only that tank has petrol in it so far. - A drain and flush, on the spot, is usually the whole job. - This is the best case — which is the whole point of step one. If it's been started, even for a moment: - From the tank, through the fuel filter, into the fuel lines: that is how far the petrol has travelled. - The high-pressure pump as well as the injectors get it on a longer run. - Lines flushed, the filter seen to, and sometimes more: this job expands as the distance does. Why the line falls there: diesel lubricates the high-pressure pump and the injectors as it flows through them, and petrol doesn't. In the tank, sitting still, petrol does no harm. Pump that petrol, though, and it grinds down the very parts that move it. ## Kingswear, petrol in a diesel: have these prepared before you call A van that circles versus a van that finds you: a little preparation is what separates them. - The ideal start is a postcode — one beginning TQ6 0 — for where you have stopped. - Name the road — Fore Street or wherever you have stopped — or the car park. - Car parks are located most easily by what they serve: tell us the one outside Co-op Food, and it's easy. - The vehicle. Make, model, plus that it's a diesel. - What was put in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Kingswear, and so say which. - Roughly how much — in litres from the receipt, or by how long the nozzle was in. - Whether it's run. And if it has, how far and how heavily. - Settle who owns the car before we turn up: some hire and company contracts want the owner to approve this work, and that is faster first. Then call 0333 366 0103. If it can wait — the car is at home and going nowhere — works too. ## Whilst you wait for a fuel drain around Kingswear During the wait, the harm comes from well-intended help — so these count. - Where the car has stopped settles where you wait. Somewhere exposed: away from it, clear of the traffic. Safe: with it. Either way, safety ahead of your car. - No one — however kind — starts it, whether to see if it runs or to move the car a short way. - Anything from your boot, oil meant for two-strokes or injector cleaner: no additive lifts that petrol. - Siphoning petrol into a can by the roadside is risky — and it also leaves whatever fuel has already gone beyond your tank. Don't try a home-made drain. - Keep the ignition off — your windows and the radio included. ## When the van gets there: your fuel drain, step by step - Three queries. What went in, how much, and if it's run. Those answers set this job, which is why our price comes after them but not before. - Out of the tank comes the tainted mix: the tank is cleared. - Cleaning the lines comes next, since a motor that ran has petrol past that tank, in the lines themselves. - Where the car has a workable filter, it's changed; if not, cleared. - The fuel system is primed on clean diesel. - The start. With clean diesel in and your system bled, it is started and tested to be sure it runs properly. Your car has clean diesel running through it before we head off. Lasting damage is very rare when it has been caught soon, so the car can go straight back to normal use. ## Kingswear, after the fuel drain: back on the road - Drive normally. There's nothing unusual to do after it has been started on clean fuel. - Pull over and ring us back if anything seems wrong early on — a light on your dash, smoke from your exhaust, an idle that runs rough, or a throttle with a dead spot. - The work may come up later with a hire company, an insurer or a fleet manager. Hold on to the paperwork. - The handle's colour is not the guide to go by next time — the label on the petrol pump is. ## About Kingswear, briefly Kingswear is a coastal village in Devon, situated on the western bank of the River Dart, opposite the town of Dartmouth.
