Here Is What Happens Whatever you do, don't switch your motor on, even briefly, to move it. Stop; leave the vehicle off. Petrol in a diesel that hasn't been run is usually a drain plus a flush, done right where your vehicle stands, and what you do in the next few minutes determines that more than anything else. From here on, step by step, wherever you are around Patchway: ## Petrol in a diesel, motor off — the first minute Before anything else, the following — following this sequence. - Bleeding the system pulls petrol from your tank toward the parts it damages, and turning the ignition on can be all it takes to do that. So your keys get taken out, and the ignition remains off altogether. - No diesel on top. More fuel in removes none of the petrol — it only leaves you with more of the same blend. - Hazard lights on. If you're at all close to moving traffic, make the car easy to see before you do anything else. - Off the petrol pump by hand. At a forecourt, get the staff to help you roll the vehicle clear of the petrol pump. Don't crank it to shift it, however short the distance. - Which fuel, and about how much? The receipt replies that, and that is where our questions start. Never throw it away. If you were still driving when you realised, pull over somewhere safe rather than pushing on for the services — on the M5, under a mile from Patchway, that means the next exit. Step one follows. ## The fork in each Patchway fuel drain: has it run yet? Everything after this point rests on one answer. If the motor has not run at all: - Nowhere but that tank: that is where the petrol still is. - Normally it's drained and purged right where your car stands. - Step one matters for exactly this reason: it is the best spot to be in. If your motor has been run, even for a moment: - The fuel lines and the fuel filter now carry petrol drawn from your tank. - Run it further and that petrol gets to your injectors, having passed through your fuel pump first. - The further it went, the larger the job — the fuel lines, the fuel filter, and sometimes more besides. Diesel keeps the high-pressure pump and the injectors protected as it goes through them. Petrol gives them nothing, and that's why the line is drawn there. A tank of petrol, left alone, damages nothing. Petrol being pumped is grinding down the parts that shift the car. ## What to have prepared when you call about petrol in a diesel from Patchway A van that circles versus a technician that finds you: a little planning is what separates them. - Your location: a postcode starting BS34 5 works best. - The street or the car park. A road name helps — Durban Road, or wherever you have stopped. - Describe a car park by what it serves — the one at Lidl, for example — and it is far easier to find. - The car. Make, model, plus that it is a diesel. - Which was put in matters: AdBlue is a separate job from petrol, and Patchway has a page just for that. So say. - How long the nozzle was in, or the litres from your receipt — either tells us how much. - Whether it has run. Then if it has, how far plus how hard. - The owner may have to approve the work under some hire and company agreements — so it's faster to settle whose vehicle it is before we arrive. Next, 0333 366 0103. Not urgent, the vehicle parked at home with nowhere to be? Then works too. ## Patchway fuel drain on its way? Whilst you wait The wait is where kindly meant help does the harm. Hold to these. - Where your car has stopped decides where you wait. Somewhere exposed: away from it, away from the traffic. Sensible: with it. Either way, safety before the car. - Nobody — however helpful — starts it, whether to see if it runs or to move your car a short way. - Anything from the boot, oil meant for two-strokes or injector cleaner: no additive lifts that petrol. - A home-made drain misses the fuel that has already gone beyond that tank, and siphoning petrol by the road is dangerous besides. - Keep the ignition off — the windows and the radio included. ## Van arrived? The fuel drain, one stage at a time - First, three questions: which fuel went in, the quantity, and has it run? Those replies decide this job, so the quote follows them. - Draining it is how the mixture gets taken from the tank. - Your lines are purged. If it ran, the petrol has moved beyond that tank, and your lines are carrying it. - Where your car has a usable filter, it is changed; if not, cleared. - The system is primed on clean diesel. - The start-up. With clean diesel in and your system bled, it's started and tested to confirm it runs smoothly. Until it runs on fresh diesel, our technicians stay with it. Your car goes back to normal use straight away, and long-term damage is very uncommon when it has been noticed soon. ## After your fuel drain: back on the road in Patchway - Nothing unusual is needed after a start with clean diesel — usual driving will do. - Watch the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle means pull over and ring us back. - Hold on to the documents. A hire company, a fleet manager or an insurer may ask what was carried out. - The handle's colour isn't the guide to go by next time — the label on the petrol pump is. ## About Patchway Patchway is a locality in South Gloucestershire, situated approximately 5.5 miles north of Bristol and 105.3 miles west of London.
