Here Is What Happens Not for a moment, and not to move it: your motor remains off. Pause there. Cleared and purged, right where it is: that is generally all an unrun diesel with petrol in it needs. Whether it stays that straightforward rests on the minutes ahead far more than on anything else. From here on, in order, for anywhere around Tooting Bec: ## Minute one: petrol in a diesel, engine off Work through these in sequence, first. - Take the keys out. Even the ignition by itself can prime the system, pulling petrol out of the tank to exactly the parts it harms, so leave the vehicle alone entirely. - No diesel on top. More fuel in takes away none of the petrol — it just makes you with extra of the same mixture. - Visibility comes before the rest beside moving traffic: put the hazards on, and only then deal with everything else. - By hand, not under your engine: that's how it leaves the petrol pump. Get the forecourt staff to help you roll, however short the distance. - Keep the receipt: the grade and the rough amount are printed on it, and they are what we ask for first. If you were still on the move when you realised, pull over somewhere safe instead of pushing on for the services — on the M4, under 10 miles from Tooting Bec, that means the next exit. Step one comes next. ## Has it run yet? The fork in each Tooting Bec fuel drain What comes next turns on one answer, and only one. Not run, not even once: - Only the tank has petrol in it for now. - Where the car stands is normally where the work happens: a drain, then a flush. - This, here, is the best spot to be in, and the whole reason step one matters. Run at all, however briefly: - Petrol has been pulled from that tank, past the filter and into your lines. - Run it farther and the petrol reaches your injectors, having gone through your fuel pump first. - Mileage is what turns it into a bigger job: flushed lines, a filter seen to, and at times more than that. Petrol does not lubricate. Diesel does, oiling your pump and injectors as it passes through, which is why the line sits where it does. A tank of petrol, left still, hurts nothing. Once it is pumped, petrol starts grinding whatever moves it. ## Calling about petrol in a diesel from Tooting Bec: what to have ready Whether the van circles or finds you comes down to a little preparation. - Your whereabouts: a postcode beginning SW17 0 serves best. - A road name helps: Selkirk Road, say, or whichever street you have stopped in. A car park does the trick too. - What a car park serves is the quickest way to find it, so mention the landmark — like the one outside Aldi. - That it is a diesel, plus the make and model of your car. - Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has its own Tooting Bec page. - The quantity: the receipt's litres, or otherwise how long you held the nozzle in. - Has it run? If so, say how far it went, and the way it was driven. - Hire or company car? Some contracts need the owner's go-ahead for the work, and getting it before our technicians arrive is quicker than afterwards. Then call 0333 366 0103. If it can wait — your car is at home with going nowhere — works as well. ## Whilst you wait for a fuel drain in Tooting Bec During the wait, the harm comes from kindly meant help — which is why these matter. - Wait with the car if it's safe where it is — but if it has stopped somewhere dangerous, you come first: away from the traffic, waiting apart from it. - No one — however helpful — starts it, whether to see if it runs or to shift the vehicle a short way. - Anything from your boot, oil meant for two-strokes or injector cleaner: no additive lifts that petrol. - A DIY drain leaves the fuel that has already gone beyond that tank, and siphoning petrol by the road is dangerous besides. - Even the radio or your windows aren't worth switching the ignition on for. ## Step by step: your fuel drain when the van gets there - Fuel, quantity, whether it's run: the answers decide this job, and that's why you get a quote after them instead of before. - Then the tank is emptied, and the polluted fuel is taken out. - Petrol that has shifted beyond the tank sits in the lines if it ran, and your lines are purged to clear it. - Then the fuel filter: changed where there's a usable one, cleared where there's not. - The fuel system is primed on fresh diesel. - The first start on fresh diesel. Once priming is done, the engine is fired up and our engineers confirm that it runs correctly. Your car has clean diesel running through it before our technicians leave. It is very rare for a vehicle spotted early to be left with long-term damage, and normal driving starts again straight away. ## Back on the road around Tooting Bec after your fuel drain - Started on fresh diesel, it asks nothing unusual of you. Just drive normally. - Give the first miles your attention. Smoke showing, a warning light coming on, your idle going lumpy or your throttle stumbling: pull over then call us back. - Your documents answers the question a rental company, fleet manager or insurer may ask: what work was carried out. Keep it. - Check the label on the pump next time, not the colour of the handle. ## About Tooting Bec and where it is Tooting Bec is a suburban area in south London, situated near the River Wandle and close to Tooting Bec Common.
