Motor off. Keep the vehicle that way — no moment on, no moving it at all. Drained then flushed, right where it sits: that's normally all an unrun diesel with petrol in it takes. Whether it remains that simple rests on the minutes ahead more than on anything else. Anywhere you happen to be around Pyrford, this is how things go from here. ## Petrol in a diesel, motor off — the first minute Before anything else, these — following this order. - Ignition off, keys out. Turned on, the ignition can prime the system — and priming is what moves petrol out of the tank into the parts it damages. - A bigger tank of the same mix is all topping up leaves you, since it removes nothing. So no extra diesel. - Make your car simple to see first — hazard lights on — if there's moving traffic anywhere near you. - However short the distance, starting it to shift it is the mistake. At a forecourt, roll the car away from the pump by hand instead, then ask the staff to help. - Which fuel, and roughly how much? The receipt replies that, and that is where our questions start. Do not bin it. On the M25, under 3 miles from Pyrford, the next exit is the spot to leave the car; anywhere, the first safe location to stop. Don't press on to the services. Then go back to stage one. ## Has it run yet? The fork in each Pyrford fuel drain From this point on, everything comes down to a single answer. If it has never been started: - The petrol is still in that tank and nowhere else. - Normally it is drained and rinsed right where the vehicle is. - Step one matters for exactly this reason: it is the best place to be in. If your motor has been run, even briefly: - Petrol has been pulled out of the tank, through the fuel filter and into the lines. - Run it further and the petrol gets to your injectors, having gone through your pump first. - Miles is what turns it into a bigger job: flushed lines, a filter seen to, and at times further work. Petrol does not lubricate. Diesel does, protecting your pump and injectors as it passes through, which is why the line sits where it does. Petrol resting in a tank damages nothing. Once it is pumped, petrol begins grinding whatever moves it. ## What to have ready when you call about petrol in a diesel from Pyrford Get ready a little, and the technician finds you rather than circling. - Your whereabouts: a postcode beginning GU22 8 serves best. - The street or the car park. A road name is a help — Coldharbour Road, or wherever you have stopped. - Or the landmark. A car park is easier to find by what it serves, like the one outside Co-op Food. - Make and model of your vehicle, and the fact it's a diesel. - What went in. Petrol, or AdBlue. AdBlue is a different job with its own page for Pyrford, so tell us which. - How much. Litres from the receipt, or how long the nozzle was in the filler. - If it has run, how far plus how heavily — and if it has run at all. - Whose car it is. Some hire or company agreements want the owner to authorise this work, and that's quicker settled before our technicians turn up than after. Ring 0333 366 0103 once you have got that together — or, if the car is at home, going nowhere, use . ## The wait for a Pyrford fuel drain, and what to do in it Stick to these: well-meant help does the damage during the wait. - Where the car has stopped decides where you wait. Somewhere exposed: away from it, away from the traffic. Safe: with it. Either way, safety before the vehicle. - Nobody — however kind — starts it, whether to see if it runs or to move the vehicle a short way. - Something from the boot, oil made for two-strokes or injector cleaner: no additive lifts that petrol. - Clearing it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and the fuel beyond your tank stays put all the same. - Not for the radio, not for the windows: your ignition stays off. ## Van arrived? Your fuel drain, one stage at a time - Our quote comes after three questions, not before them — what went in, how much, and whether it's run — since the replies decide the job. - Draining it's how that mixture gets taken from that tank. - The fuel lines are flushed. If it ran, the petrol has moved beyond the tank, and the lines are carrying it. - Where the car has a workable filter, it's swapped; otherwise, cleared. - Fresh diesel goes in, and the fuel system is primed. - Our technicians fire it up only after fresh diesel has gone in and primed the fuel system, then make sure that it is running correctly. Until it runs on fresh diesel, we stay with it. The car returns to normal use right away, and long-term damage is very uncommon if it has been noticed soon. ## After the fuel drain is done: driving around Pyrford once more - Nothing unusual is needed after a start with clean diesel — normal driving is all. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop and ring us a second time. - The documents answers the query a rental company, fleet manager or insurer may ask: what work was carried out. Keep it. - Read the label on the pump next time, not the colour of the handle. ## About Pyrford itself Pyrford is a village in Surrey, situated inland at an elevation of 38 metres, approximately 20 miles south-west of central London.
