The coming few minutes decide it far more than anything else: petrol in a diesel still unrun usually comes down to draining and purging, on the spot. Wherever you are around Cooksongreen, this is how things go from now. ## Petrol in a diesel, engine off — the first minute Work through the following first, in this sequence. - Pull the keys out. Even your ignition on its own can prime your fuel system, pulling petrol out of the tank to exactly the components it damages, so leave the car off completely. - Topping up with diesel seems like it dilutes the issue. It doesn't: nothing comes out, and that tank just holds more of the same. - Get the vehicle simple to see before anything else — hazard lights on — if there's traffic going past anywhere close to you. - Off the petrol pump by hand. On a forecourt, ask the staff to help you push the vehicle clear of the petrol pump. Do not fire it up to move it, however short the way. - The first question we will ask is which fuel you put in and about how much — and the receipt shows both. Keep it. If you were still on the move when you realised, pull over somewhere safe instead of pushing on for the services — on the M56, under 5 miles from Cooksongreen, that means the next junction. Stage one comes next. ## Has it run yet? The fork in every Cooksongreen fuel drain What comes next rests on one answer, and only one. Not run, not even once: - The petrol is still in the tank and nowhere else. - Draining and flushing, on the spot, is normally the whole job. - No place is better, and it's why the first stage counts so much. If it's been started, even for a second: - From your tank, past the fuel filter, into the lines: that is how far that petrol has got. - Run it further and that petrol gets to the injectors, having gone through your pump first. - The job expands with the mileage — lines rinsed, filter seen to, sometimes more. Petrol doesn't lubricate. Diesel does, protecting the pump and injectors as it passes through, which is why the line sits where it does. In your tank, sitting still, petrol does no harm. Pump that petrol, though, and it grinds down the very parts doing the moving. ## What to have prepared when you call about petrol in a diesel from Cooksongreen Prepare a little, and the van finds you rather than circling. - Your whereabouts: a postcode starting CW8 2 works best. - Give the street — Gabriel Bank or wherever you have stopped — or the car park. - What a car park serves is the easiest way to find it, so say the landmark — such as the one outside Co-op. - Make and model of your car, and the fact it is a diesel. - Which went in matters: AdBlue is a separate job from petrol, plus Cooksongreen has a page for it. So say. - How long the nozzle was in, or the litres on your receipt — either tells us how much. - The distance it covered, and how heavily, if it ran at all. - The owner may have to approve the work under some hire or company contracts — which is why it's faster to settle whose vehicle it is before our technicians arrive. Then call 0333 366 0103. If it can wait — the vehicle is at home with going nowhere — works as well. ## The wait for a Cooksongreen fuel drain, and what to do in it In the wait, the harm comes from well-intended help — which is why these matter. - Your safety comes before the vehicle. Somewhere dangerous? Get away from the traffic then wait away from it. Safe where it sits? Stay with it. - A kind passer-by does not crank it. Nor does anyone checking it still works, or moving it a few yards. - None of it gets the petrol back out — not two-stroke oil, not injector cleaner, not anything from your boot. So no additives. - Clearing it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and your fuel beyond your tank remains put all the same. - Leave your ignition off — the windows and the radio too. ## The fuel drain, step by step, once our van gets there - First, three questions: which fuel went in, the amount, and has it run? Those answers decide the job, and so our price follows them. - Next that tank is emptied, so the tainted fuel comes out. - Purging the lines follows, since a motor that ran has petrol past the tank, in the lines themselves. - Then your filter: swapped where there's a serviceable one, cleared where there is not. - Clean diesel in, and the fuel system primed. - Starting it. When the system is primed with new diesel, our technicians start it and confirm it runs smoothly. We stay until it is running on fresh diesel. When it has been caught early, permanent damage is very uncommon, and the car returns to normal driving right away. ## Back on the road in Cooksongreen after your fuel drain - Started on fresh diesel, it needs nothing unusual of you. Just drive normally. - Watch the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle tells you to pull over and call us back. - Keep your documents. A hire firm, a fleet manager or an insurer may ask what was carried out. - Next time, read the pump. The label, not the colour of its handle. ## About Cooksongreen, briefly Cooksongreen is a locality situated on the riverside in Cheshire, with an elevation of 19 metres above sea level.
