Here Is What Happens Whatever you do, never switch your engine on, even for a moment, to move the car. Stop; leave the vehicle off. Has not been run? Then petrol in a diesel tends to be a straightforward drain-and-flush job wherever the car has stopped — and nothing settles that as much as the next few minutes do. From here on, step by step, for anywhere in Elm Tree: ## Petrol in a diesel, engine off — the first minute Go through the following in order, before you do anything else. - Priming your fuel system draws petrol from your tank toward the components it harms, and switching your ignition on can be enough to do that. So your keys get taken out, and your ignition stays off altogether. - A fuller tank of the same mix is all adding diesel gives you, since it takes out nothing. So no more diesel. - Close to moving traffic? Then the hazard lights go on before everything else, so the vehicle is easy to spot. - Off the pump by hand. At a forecourt, get the staff to help you push the vehicle clear of the pump. Don't start the car to shift it, however short the distance. - Keep the till receipt: the fuel and the rough amount are written on it, and they are what our technicians ask about first. On the A1(M), under 10 miles from Elm Tree, the next exit is the spot to leave it; elsewhere, the first sensible place to stop. Don't press on to the services. Then go back to stage one. ## Each Elm Tree fuel drain starts here: has the engine run? From this stage on, everything comes down to a single answer. If your motor hasn't run at all: - No place but that tank: that's where the petrol still is. - Normally it is emptied and purged just where your car is. - No spot is better, and it's why the first step counts so much. Engine run, even for a moment? - From your tank, through your filter, into your lines: that is how far that petrol has travelled. - The high-pressure fuel pump as well as the injectors get it on a bigger run. - Mileage is what makes it a bigger job: the lines flushed, a filter seen to, and at times more than that. Why the line falls there: diesel lubricates the high-pressure pump and the fuel injectors as it passes through them, and petrol does not. Petrol resting in a tank harms nothing. Petrol being pumped is grinding down the parts that move the car. ## Elm Tree, petrol in a diesel: have these prepared before you call Get ready a little, and the technician finds you instead of circling. - The best place to start is a postcode — one beginning TS19 0 — for where you have stopped. - Wherever you have pulled up, the road's name is useful — whether that's Foxwood Drive 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 Sainsbury's, and it is simple. - The make and model of the car, and the fact it is a diesel. - Which went in counts: AdBlue is a separate job from petrol, plus Elm Tree has a page just for that. So say. - How long the nozzle was in, or the litres on your receipt — whichever tells us how much. - Has it run? If so, tell us how far it got, and how it was driven. - Settle who has the vehicle before we get there: some hire or company agreements want the owner to authorise the work, and that is quicker first. Then ring 0333 366 0103. If it can wait — the car is at home with going nowhere — works too. ## Waiting for a fuel drain in Elm Tree: what to do During the wait, the damage comes from kindly meant help — which is why these count. - Wait with your car if it is safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it. - Not to roll it a few yards, not to check it is all right, not as a passer-by's kindness: no one starts it. - No additives. Two-stroke oil, injector cleaner, anything from your boot — none of it takes the petrol back out. - No DIY draining. Siphoning petrol into a can by the kerbside is risky, and it leaves your fuel that has already gone beyond the tank. - Even the radio or the windows aren't worth switching the ignition on for. ## When the van gets there: the fuel drain, step by step - Our price comes after three queries, not before them — what went in, how much, and if it's run — because those replies set this job. - The tank is cleared. The polluted mix comes from your tank. - Purging the fuel lines follows, since a vehicle that ran has petrol past that tank, in the fuel lines themselves. - Cleaned, or swapped if the car has a workable one: your filter is seen to next. - Clean diesel goes in, and the system is primed. - The first start on clean diesel. Once bleeding is finished, your engine is fired up and our technicians make sure that it runs correctly. Your car has new diesel running through it before our engineers head off. When it has been caught quickly, lasting damage is very uncommon, and the car returns to normal driving right away. ## Back on the road around Elm Tree after your fuel drain - Once it has been started on fresh fuel, there is nothing unusual to do: drive normally. - Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or the throttle stumbling: pull over then call us back. - Your paperwork covers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Check the label on the pump next time, not the colour of its handle. ## About Elm Tree and where it is Elm Tree is a suburban area situated on the riverside in County Durham, with a mix of housing types but predominantly detached homes.
