Stop; leave the vehicle off. Cleared and flushed, just where it is: that is generally all an unrun diesel with petrol in it needs. Whether it remains that straightforward rests on the minutes ahead more than on anything else. Here is the order of things from here, anywhere you are in Startforth. ## Minute one: petrol in a diesel, motor off Do these first, in this order. - Priming the system draws petrol from the tank toward the parts it damages, and switching the ignition on can be enough to do that. So your keys come out, and your ignition stays off altogether. - A fuller tank of the same mixture is all adding diesel leaves you, since it takes out nothing. So no more diesel. - Being seen comes first near moving traffic: switch the hazard lights on, and only then think about anything else. - However short the distance, starting it to move it is the mistake. At a forecourt, push the car away from the pump by hand instead, and ask the attendants to lend a hand. - Which fuel, and roughly how much? The receipt answers that, and that's where our questions start. Do not throw it away. If you were still driving when you noticed, pull over somewhere sensible rather than pushing on for the services — on the A1(M), under 15 miles from Startforth, that means the next exit. Step one follows. ## Each Startforth fuel drain starts here: has your motor run? What comes after this rests on one answer, and just one. Not run, not even briefly: - That petrol is still in the tank and nowhere else. - Where the car sits is usually where this work happens: a drain, then a flush. - This is the best case — which is the whole point of step one. Engine run, however briefly? - Petrol has been pulled out of the tank, past the fuel filter then into the lines. - A longer run carries it all the way to the high-pressure fuel pump and your injectors. - The farther it went, the larger this job — the fuel lines, the filter, and now and then more besides. The reason the line falls there: diesel protects your high-pressure pump as well as your injectors as it flows through them, and petrol does not. Petrol sitting in a tank damages nothing. Petrol being pumped is grinding down the parts that shift the vehicle. ## Before you call about petrol in a diesel around Startforth: what our technicians need Whether the van circles or finds you depends on a little planning. - Where you are. A postcode starting DL12 9 is the ideal place to start. - Wherever you have parked, the road's name helps — whether that is Dark Lane or somewhere else — and so does the name of a car park. - Name a car park by what it serves — the one outside Heron Foods, for instance — and it is far quicker to find. - Say what your vehicle is — make, model — and check it is diesel. - What got in. Petrol, or AdBlue. AdBlue is a different job with its own page for Startforth, so say which. - Roughly how much — in litres from your receipt, or by how long the nozzle stayed in. - Has it run? If so, tell us how far it went, and how it was driven. - The owner may have to approve this work under some hire and company agreements — which is why it's quicker to settle whose motor it is before our technicians arrive. Then phone 0333 366 0103. If it can wait — the vehicle is at home with going nowhere — works as well. ## The wait for a Startforth fuel drain, and what to do in it The wait is where kindly meant help does the damage. Stick to these. - Safety before your car. If it has stopped somewhere exposed, get yourself away from the traffic and wait away from it. If it's safe where it sits, stay with it. - No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll it a couple of yards. - Additives remain in your boot. Injector cleaner and two-stroke oil take none of that petrol out again. - Emptying it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and your fuel beyond your tank stays where it is anyway. - Keep your ignition off — your windows and your radio too. ## The fuel drain, step by step, after the van arrives - The price comes after three queries, not before them — what was put in, how much, and if it has run — since the answers shape the job. - That tank is cleared. The contaminated blend comes out of your tank. - Purging the lines comes next, because a motor that ran has petrol past the tank, inside the fuel lines themselves. - Cleared, or swapped if the vehicle has a serviceable one: the filter is dealt with next. - Priming comes once fresh diesel is in. - Starting up. Once the fuel system is primed with new diesel, we start the engine and check it runs smoothly. Only when it's running on new diesel do we go. The car goes back to normal driving straight away, and long-term damage is very uncommon if it has been noticed soon. ## Startforth, after your fuel drain: back on the road - After it's been started on fresh fuel, there's nothing special to do: drive normally. - Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or your throttle hesitating: pull over and call us back. - Hold on to the documents. A hire company, a fleet manager or an insurer may ask what was done. - Next time, trust the pump's label rather than the colour of its handle. ## About Startforth itself Startforth is a village situated on the riverside in County Durham, with a population of around 1391 people.
