Here Is What Happens Whatever you do, don't switch the engine on, even for a moment, to shift it. Pause; leave the vehicle off. Petrol in a diesel that has not been run is normally a simple drain and a flush, done where the vehicle stands, and what you do in the next few minutes determines that far more than anything else. Here is the order of things from here, anywhere you are in Wool. ## Engine off: minute one with petrol in a diesel Work through these first, in this sequence. - The ignition off, keys out. Turned on, the ignition can prime the system — and priming is what draws petrol out of the tank into the parts it damages. - A bigger tank of the same mix is all adding diesel gives you, because it takes out nothing. So no more diesel. - Close to passing traffic? Then the hazard lights come on before everything else, and so the vehicle is easy to see. - The staff will usually help you push it clear of the petrol pump. Ask, then move it by hand — not on the motor, even for a couple of yards. - Keep your receipt: the fuel and roughly how much are written on it, and they're what our technicians ask for first. Realised on the move? Get off at the next junction if you're on the M27, under 50 miles from Wool, and stop somewhere sensible — not at the services further on. Step one comes after that. ## The fork in each Wool fuel drain: has it run yet? What comes after this rests on one answer, and only one. If it has never been started: - All the petrol remains inside your tank, and just there. - Usually it is drained and purged right where the vehicle stands. - This, here, is the best spot to be in, and the whole reason step one counts. If it's been started, even for a second: - Your lines and the filter now carry petrol pulled out of the tank. - On a longer run it has reached the high-pressure pump as well as your injectors. - Distance is what makes it a larger job: flushed lines, a filter seen to, and at times more than that. Diesel keeps the high-pressure fuel pump and the fuel injectors oiled as it runs through them. Petrol gives them nothing, and that is why the line is drawn there. In that tank, sitting still, petrol harms nothing. Petrol being pumped is wearing the components that move it. ## Calling about petrol in a diesel from Wool: what to have ready A technician that circles against a technician that finds you: a little preparation is the difference. - BH20 6 plus the rest of the postcode makes the best way to start telling us where you are. - Wherever you have pulled up, the road's name is useful — whether that is The Cross or somewhere else — and so does the name of a car park. - What a car park serves is the easiest way to find it, and so mention the landmark — such as the one at The Co-operative Food. - Tell us what the car is — make, model — and check it's diesel. - Which went in matters: AdBlue is a separate job from petrol, plus Wool has a page for it. So tell us. - About how much — in litres from the receipt, or by how long the nozzle was in. - Whether it has run. And if it has, how far plus how heavily. - Settle who owns the vehicle ahead of when we turn up: some hire and company agreements want the owner to authorise this work, and doing it faster beforehand. Call 0333 366 0103 next. Writing to is fine too if it can wait, with the car parked at home, going nowhere. ## Wool fuel drain on its way? Whilst you wait Help, however well meant, is what does the harm while you wait. So stick to these. - Stay with your car if it's safe where it is — but if it has stopped somewhere dangerous, you come first: away from the traffic, waiting apart from it. - No one — however kind — starts it, whether to see if it runs or to shift the vehicle a short way. - Additives stay in your boot. Injector cleaner and two-stroke oil take none of the petrol out again. - Emptying it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and the fuel beyond the tank stays where it is all the same. - Keep your ignition off — your windows and the radio included. ## When the van gets there: your fuel drain, step by step - First, three questions: which fuel went in, the volume, and has it run? Those answers set this job, so our price follows them. - Then your tank is emptied, and the contaminated fuel is taken out. - Petrol that has shifted beyond the tank sits in the fuel lines once it ran, and the lines are purged to shift it. - The fuel filter is sorted. Cleared, or replaced where the car has a serviceable one. - Clean diesel goes in, then your system is primed. - Starting the car. Once your system is primed with fresh diesel, our technicians fire it up and confirm it runs correctly. Until it runs on fresh diesel, our technicians remain with it. Your car goes back to normal driving right away, and permanent damage is very rare when it has been caught early. ## Once the fuel drain is done: driving around Wool once more - Once it has been started on clean fuel, there's nothing unusual to do: drive normally. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop then call us a second time. - Keep the paperwork. A hire firm, a fleet manager or an insurer may ask what was carried out. - Next time, trust the pump's label instead of the colour of its handle. ## About Wool, briefly Wool is a village in Dorset, situated on the banks of the River Frome at an elevation of 19 metres.
