Here Is What Happens Stop. Motor off. Keep the vehicle that way — no second on, no moving it at all. Hasn't been run? Then petrol in a diesel will usually be a straightforward drain-and-flush job wherever your car has stopped — and no other factor settles that more than these next few minutes do. What follows is the sequence from here, wherever in Brook Green you happen to be. ## Engine off: minute one with petrol in a diesel Do the following first, in this order. - Priming the fuel system pulls petrol from your tank towards the components it harms, and switching the ignition on can be enough to do that. So the keys come out, and the ignition remains off altogether. - No diesel on top. More fuel in removes none of that petrol — it only makes you with extra of the same mixture. - Make the vehicle easy to see first — hazards on — if there's traffic going past anywhere close to you. - The attendants will normally help you roll it clear of the pump. Let them, and roll it by hand — never on the engine, even for a few yards. - Hold on to your receipt. It shows which fuel got in plus about how much, which is the first thing we'll ask. Still driving when you noticed? Come off the M4 at the next junction if that's where you are, under 3 miles from Brook Green, and stop somewhere sensible rather than pressing on to the services. Then begin at stage one. ## Brook Green fuel drain: has the motor run yet, or not? What happens after this turns on one answer, and only one. If your engine has not run at all: - Nowhere but the tank: that's where the petrol yet is. - Normally it is emptied and cleaned just where the car stands. - This is the best case — which is the entire point of step one. Run at all, however briefly: - Petrol has been pulled from that tank, past your filter then into your lines. - Run it farther and that petrol reaches your injectors, having passed through your pump first. - Lines flushed, your filter sorted, and sometimes more: this job grows as the mileage does. The reason the line falls there: diesel lubricates your high-pressure pump and your injectors as it passes through them, and petrol does not. A tank of petrol, left alone, damages nothing. Petrol being pumped is wearing the components that shift the car. ## Brook Green, petrol in a diesel: have these ready before you call Prepare a little, and the van finds you rather than circling. - The ideal place to start is a postcode — one beginning W6 7 — for where you have stopped. - Name the street — Brook Green or wherever you have pulled up — or the car park. - What a car park serves is the quickest way to find it, and so mention the landmark — like the one at Olympia Foods. - That it is a diesel, plus the make and model of your vehicle. - Tell us which went in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Brook Green. - The quantity: the receipt's litres, or otherwise how long you had the nozzle in. - If it has run, how far plus how hard — as well as whether it's run at all. - Settle who owns your car ahead of when we get there: some hire or company agreements want the owner to authorise the work, and doing it faster first. Next, 0333 366 0103. Not urgent, your car parked at home with nowhere to be? Then works too. ## The wait for a Brook Green fuel drain, and what to do in it Hold to these: well-intended help does the harm during the wait. - Wait with your car if it's safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it. - Not to roll it a couple of yards, not to check it is all right, not for a passer-by's favour: no one starts it. - No additives. Two-stroke oil, injector cleaner, something from the boot — none of that gets the petrol back out. - No DIY emptying. Siphoning petrol into a can at the roadside is risky, and it leaves your fuel that has by now gone beyond your tank. - Not for the radio, not for the windows: your ignition stays off. ## The fuel drain, step by step, after our van arrives - Fuel, quantity, whether it has run: the replies decide the job, and that's why you get a price after them rather than before. - Then the tank is drained, so the contaminated fuel is taken out. - Cleaning your lines follows, because a vehicle that ran has petrol past the tank, inside the fuel lines themselves. - Then your filter: changed where there's a workable one, cleared where there's not. - The system is primed on fresh diesel. - The first start on new diesel. When priming is done, your engine is fired up and our technicians confirm that it runs properly. Till it runs on new diesel, our technicians stay with it. Lasting damage is very rare when it has been spotted soon, so your car can go straight back to normal driving. ## After the fuel drain: back on the road around Brook Green - Once it's been started on clean fuel, there is nothing special to do: drive normally. - Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or your throttle stumbling: pull over then call us back. - The work may matter later with a hire firm, an insurer or a fleet manager. Hold on to your paperwork. - Check the label on the petrol pump next time, not the colour of its handle. ## About Brook Green itself Brook Green is a suburban area in west London, situated near the Thames River and close to neighbouring districts such as West Kensington and Hammersmith.
