Here Is What Happens Whatever you do, don't switch your engine on, even briefly, to move the car. Stop; leave the car 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 no other factor decides that as much as these next few minutes do. From here on, step by step, for anywhere in Prior Park: ## Minute one: petrol in a diesel, motor off Go through these in sequence, before you do anything else. - Bleeding the system pulls petrol from your tank toward the components it damages, and switching the ignition on can be enough to do that. So the keys come out, and the ignition stays off altogether. - Topping up with diesel sounds like it dilutes the issue. It does not: nothing comes out, and your tank simply holds more of the same. - Hazard lights on. If you are anywhere close to moving traffic, make the car simple to see before you do anything else. - Off the petrol pump by hand. On a forecourt, get the staff to help you push the car away from the petrol pump. Do not start the vehicle to move it, however short the way. - Keep your receipt. It shows which fuel went in plus about how much, which is the first thing we'll ask. Still driving when you realised? Come off the M8 at the next junction if that's where you are, over 50 miles from Prior Park, and stop somewhere sensible rather than pressing on to the services. Then begin at step one. ## The fork in each Prior Park fuel drain: has it run yet? Everything after this stage rests on one answer. Not run, not even briefly: - The petrol is still inside that tank and nowhere else. - Draining and flushing, on the spot, is usually all of it. - This is the best place to be in, and the reason stage one counts. Engine run, however for a moment? - Petrol has been drawn from that tank, past the fuel filter and into the lines. - The high-pressure fuel pump as well as the injectors see it too on a longer run. - The farther it went, the larger the job — the lines, the filter, and sometimes more besides. Petrol does not lubricate. Diesel does, protecting your high-pressure pump and injectors as it flows through, which is why the line sits where it does. A tank of petrol, left still, damages nothing. Once it's pumped, petrol begins wearing down whatever moves it. ## Before you call about petrol in a diesel in Prior Park: what our engineers need A little planning is the difference between a van that finds you and a technician that circles. - Where you have stopped. A postcode starting TD15 2 is the ideal start. - A road name helps: Valley View, say, or whichever street you have stopped in. A car park does the trick too. - Or the landmark. A car park is easier to find by what it serves, such as the one at M&S Foodhall. - Tell us what your vehicle is — make, model — and confirm it's diesel. - Tell us which was put in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Prior Park. - How much. Litres from the receipt, or how long the nozzle was in. - The miles it covered, and how hard, if it has run at all. - Whose motor it is. Some hire or company agreements want the owner to approve the work, and that's easier settled before we get there than after. Call 0333 366 0103 next. Writing to works as well if it can wait, with the car parked at home, going nowhere. ## Prior Park fuel drain on its way? Whilst you wait In the wait, the damage comes from well-intended help — which is why these count. - Wait with the vehicle 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 for a passer-by's favour: nobody starts it. - No additives. Two-stroke oil, injector cleaner, something from the boot — none of it takes the petrol back out. - Siphoning petrol into a can at the roadside is hazardous — and it also leaves whatever fuel has already gone beyond that tank. Don't drain the car yourself. - Not for the radio, not for the windows: the ignition stays off. ## When the van gets there: the fuel drain, step by step - First, three questions: which fuel got in, the quantity, and has it run? Those replies shape this job, and so our quote follows them. - Draining it's how the blend gets taken from the tank. - The fuel lines are cleaned. If it ran, the petrol has shifted beyond your tank, and your lines are holding it. - Cleaned, or replaced if the car has a workable one: the filter is sorted next. - Fresh diesel in, and your system primed. - The first start on new diesel. When priming is done, the motor is fired up and we check that it runs properly. We wait until it is running on new diesel. Permanent damage is very uncommon if it has been spotted soon, so your car can go right back to normal use. ## After your fuel drain: back on the road around Prior Park - Drive normally. There's nothing special to do after it has been started on fresh fuel. - Give the first miles your attention. Smoke showing, a warning light coming on, your idle going lumpy or your throttle stumbling: pull over and ring us back. - An insurer, a fleet manager or a hire firm may ask what was carried out, and so hold on to the paperwork. - The handle's colour is not the thing to go by next time — the label on the pump is. ## About Prior Park Prior Park is a suburban area in Northumberland, situated near the coast and approximately 41 metres above sea level.
