Stop there. Drained then cleaned, right where it is: that is usually all an unrun diesel with petrol in it needs. Whether it remains that simple depends on the minutes ahead more than on everything else. From here on, step by step, wherever you are around Tedburn St Mary: ## Petrol in a diesel? What to do in minute one In this sequence, all before everything else: - Take the keys out. Even your ignition on its own can prime the fuel system, drawing petrol out of your tank to precisely the parts it harms, so leave the car alone wholly. - Topping up with diesel sounds like it dilutes the problem. It doesn't: nothing comes out, and your tank just carries more of the same. - Near moving traffic? Then the hazards go on before anything else, and so the car is simple to see. - The attendants will usually help you push it away from the petrol pump. Let them, then roll it by hand — not under the engine, even for a couple of yards. - Hold on to your receipt: the grade and roughly how much are written on it, and they are what our engineers ask about first. Still driving when you realised? Come off the M5 at the next exit if that's where you are, under 10 miles from Tedburn St Mary, and stop somewhere sensible rather than pushing on to the services. Then start at step one. ## The fork in each Tedburn St Mary fuel drain: has it run yet? Everything after this point depends on one answer. Not run, not even once: - The petrol remains inside your tank, and only there. - The job is a drain and a flush, usually done where the car stands. - Step one matters for precisely this reason: it is the best spot to be in. Motor run, however for a moment? - The lines and the filter now hold petrol drawn out of that tank. - The high-pressure fuel pump as well as your injectors see it too on a bigger run. - The farther it went, the larger this job — your lines, the filter, and now and then more besides. That line falls there since diesel protects the high-pressure pump and your injectors on its way through them — and petrol doesn't. In the tank, sitting still, petrol does no harm. The components that shift it are wearing the moment petrol is being pumped. ## What to have ready when you call about petrol in a diesel from Tedburn St Mary A technician that circles versus a van that finds you: a little preparation is what separates them. - EX6 6 and the remainder of the postcode is the ideal way to begin telling us where you are. - Wherever you have parked, the road's name is useful — whether that is Huish Lane End or somewhere else — and so does the name of a car park. - Car parks are located most easily by what they serve: say the one at Tesco, and it's straightforward. - Say what your car is — make, model — and check it's diesel. - Which was put in matters: AdBlue is a separate job from petrol, plus Tedburn St Mary has a page for it. So say. - About how much — in litres from your receipt, or by how long the nozzle was in. - Whether it has run. And if it has, how far and how hard. - Settle who owns the car ahead of when our engineers get there: some hire or company contracts want the owner to authorise this work, and that is faster beforehand. Then call 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — works too. ## The wait for a Tedburn St Mary fuel drain, and what to do in it Help, however well meant, is the thing that does the damage whilst you wait. So stick to these. - Your safety comes before your car. Somewhere exposed? Get away from the traffic then wait away from it. Fine where it stands? Stay with it. - A kind passer-by does not fire it up. Nor does anybody wanting to check it still does the trick, or moving it a couple of yards. - No additives. Two-stroke oil, injector cleaner, something from your boot — none of it takes that petrol back out. - Draining it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and your fuel beyond that tank stays where it is regardless. - Ignition stays off. Even for the radio or the windows. ## When the van arrives: the fuel drain, step by step - Fuel, quantity, whether it has run: those answers decide the job, and that's why we give a quote after them instead of before. - That tank is emptied. The tainted mixture comes from the tank. - Flushing the fuel lines comes next, since a motor that ran has petrol past that tank, inside the lines themselves. - Where the vehicle has a workable filter, it's changed; if not, cleared. - Fresh diesel goes in, and the fuel system is primed. - The start. With new diesel in and your system primed, it is started and tested to make sure it runs properly. Your car has clean diesel running through it before we leave. When it has been noticed quickly, permanent damage is very unusual, and the vehicle returns to normal use straight away. ## Tedburn St Mary, after the fuel drain: back on the road - Once it's been started on fresh fuel, there is nothing special to do: drive normally. - Pull over and call us back if anything looks 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. Keep your documents. - The handle's colour isn't the thing to go by next time — the label on the petrol pump is. ## About Tedburn St Mary itself Tedburn St Mary is a village in Devon, situated near the River Exe and close to the city of Exeter.
