Engine off. Leave the vehicle like that — no moment on, no moving it anywhere. The next few minutes decide it more than anything else: petrol in a diesel still unrun normally amounts to draining then purging, on the spot. Anywhere you happen to be around Pennycomequick, here is the order things go from now. ## Petrol in a diesel? What to do in minute one Work through the following in order, first. - Pull the keys out. Even the ignition on its own can prime the system, drawing petrol out of the tank to precisely the components it harms, so keep the car off entirely. - Do not top it up with diesel. Adding diesel takes out nothing. You end up with a bigger tank of the same mix. - Get the car simple to see before anything else — hazards on — if there is traffic going past anywhere near you. - However short the way, starting it to move it is the mistake. At a forecourt, roll the vehicle away from the petrol pump by hand instead, then ask the staff to help. - Which fuel, and about how much? The receipt answers both, and that is where our questions start. Never throw it away. On the M5, under 50 miles from Pennycomequick, the next junction is the place to leave it; elsewhere, the first sensible location to stop. Do not push on to the services. Then go back to step one. ## Every Pennycomequick fuel drain starts here: has the engine run? What comes next rests on one answer, and only one. If it has never been started: - The petrol sits in that tank, and just there. - Draining and flushing, on the spot, is normally the whole job. - Step one counts for exactly this reason: it's the best spot to be in. Motor run, however for a moment? - Some petrol has left the tank already, gone through the filter, and reached your lines. - On a longer run it has reached the high-pressure fuel pump and the fuel injectors. - Mileage is what makes it a larger job: the lines flushed, a filter seen to, and at times further work. Diesel keeps the high-pressure pump and the fuel injectors lubricated as it goes through them. Petrol offers them nothing, and that is why the line is drawn there. In that tank, left alone, petrol harms nothing. Petrol being pumped is grinding down the components that move the vehicle. ## Pennycomequick, petrol in a diesel: have these ready before you call A technician that circles versus a technician that finds you: a little preparation is what separates them. - PL3 4 and the remainder of the postcode is the ideal way to begin telling us where you are. - Wherever you have pulled up, the road's name helps — whether that is Alma Road or somewhere else — and so does the name of a car park. - Or the nearest landmark. A car park is quicker to find by what it serves, like the one outside Sainsbury's. - The make and model of the car, and the fact it's a diesel. - Which got in counts: AdBlue is a separate job from petrol, plus Pennycomequick has a page for it. So tell us. - Roughly how much — in litres from the receipt, or by how long the nozzle stayed in. - If it has run, how far plus how hard — and whether it's run at all. - Hire or company car? Some contracts need the owner's go-ahead for this work, and getting it before we turn up is quicker than after. Then ring 0333 366 0103. If it can wait — the car is at home with going nowhere — does the trick as well. ## Pennycomequick fuel drain on its way? While you wait Hold to these: well-intended help does the harm during the wait. - Safety before the car. If it has stopped somewhere exposed, get yourself away from the traffic and wait away from it. If it is safe where it stands, stay with it. - Not to roll it a few yards, not to check it is all right, not for a passer-by's kindness: nobody starts it. - Additives stay in the boot. Injector cleaner and two-stroke oil draw none of that petrol out a second time. - Siphoning petrol into a can by the roadside is dangerous — and it also leaves whatever fuel has already gone beyond that tank. Don't drain it yourself. - Even the radio or your windows are not worth turning the ignition on for. ## Step by step: your fuel drain when our van gets there - First, three questions: which fuel went in, the quantity, and has it run? Those replies set the job, and so the quote follows them. - That tank is cleared. The polluted mixture comes out of the tank. - Flushing your lines follows, since a motor that ran has petrol past the tank, inside the fuel lines themselves. - Where the vehicle has a serviceable filter, it's replaced; if not, cleared. - Fresh diesel goes in, then the fuel system is primed. - The start-up. With clean diesel in and the fuel system primed, it is fired up and tested to make sure it runs smoothly. Our technicians wait until it's running on fresh diesel. The car returns to normal driving at once, and permanent damage is very rare if it has been noticed soon. ## Back on the road in Pennycomequick after the fuel drain - Nothing unusual is needed after a start with fresh diesel — normal driving is all. - Pull over and call us back if anything seems 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 matter later with a hire firm, an insurer or a fleet manager. Hold on to the paperwork. - Check the label on the pump next time, not the colour of the handle. ## About Pennycomequick, briefly Pennycomequick is a suburban area in Devon, situated near the coast and close to the city of Plymouth.
