Engine off. Leave the vehicle that way — no second on, no shifting it anywhere. The next few minutes decide it far more than anything else: petrol in a diesel that has not run normally amounts to clearing then cleaning, right there. From here on, step by step, for anywhere in Finney Green: ## Petrol in a diesel, motor off — the first minute First, these — following this order. - The keys out of your ignition. Turning the ignition on can be enough to prime your fuel system, while priming pulls petrol out of the tank towards the components it harms. Keep it off completely. - A bigger tank of the same mixture is all adding diesel gives you, since it removes nothing. So no extra diesel. - Visibility comes first near moving traffic: put the hazards on, and only then think about everything else. - Off the pump by hand. On a forecourt, get the attendants to help you roll the vehicle away from the petrol pump. Don't start the vehicle to shift it, however short the distance. - Keep the till receipt: the fuel and roughly how much are printed on it, and they're what we ask for first. On the M56, under 3 miles from Finney Green, the next exit is the location to leave the vehicle; elsewhere, the first safe place to stop. Do not push on to the services. Then go back to step one. ## The fork in each Finney Green fuel drain: has it run yet? From this point on, everything comes down to a single answer. If it has not once been started: - Nowhere but the tank: that is where the petrol still is. - Usually it is emptied and cleaned right where your car is. - Being here is the best case — which is the entire point of step one. If it has been started, even for a second: - Petrol has been drawn out of the tank, through the filter then into your lines. - The high-pressure pump and the injectors get it on a longer run. - Distance is what turns it into a larger job: flushed lines, a filter seen to, and at times further work. Petrol does not lubricate. Diesel does, oiling your pump and injectors as it passes through, which is why the line sits where it does. In that tank, sitting still, petrol does no harm. The parts that shift it are grinding the moment petrol is being pumped. ## What to have ready when you call about petrol in a diesel from Finney Green A little preparation is the difference between a technician that finds you and a van that circles. - Your whereabouts: a postcode starting SK9 2 serves best. - The road or the car park. A road name is a help — Stanneylands Road, or wherever you have stopped. - Name a car park by what it serves — the one at Lidl, for instance — and it is far easier to find. - Make and model of your car, and the fact it's a diesel. - Tell us which got in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Finney Green. - About how much — in litres from the receipt, or by how long the nozzle stayed in. - Has it run? If so, tell us how far it got, and the way it was driven. - Hire or company car? Some contracts want the owner's authorisation for the work, and sorting it before we turn up is quicker than afterwards. Call 0333 366 0103 once you've got that ready — or, if the car is at home, going nowhere, use . ## Finney Green fuel drain on its way? While you wait In the wait, the damage comes from well-intended help — so these matter. - Safety before the car. If it has stopped somewhere unsafe, get yourself clear of the traffic then wait away from it. If it is safe where it is, wait with it. - A kind passer-by does not start it. Nor does anyone checking it still works, or moving it a few yards. - No additives. Two-stroke oil, injector cleaner, anything from the boot — none of it gets the petrol back out. - A DIY drain misses the fuel already gone beyond that tank, and siphoning petrol by the road is dangerous besides. - Ignition stays off. Even for your radio or the windows. ## Step by step: the fuel drain when the van gets there - First, three questions: which fuel was put in, the quantity, and has it run? Those replies decide the job, and so our quote follows them. - Out of your tank comes the tainted mixture: the tank is cleared. - Petrol that has moved beyond your tank sits in the lines if it ran, and the fuel lines are purged to clear it. - Where your car has a workable filter, it's swapped; if not, cleared. - Your system is primed with fresh diesel. - Our engineers fire it up only after clean diesel has gone in and bled the fuel system, then make sure that it's running smoothly. The vehicle has clean diesel running through it before our technicians head off. Lasting damage is very uncommon when it has been caught early, so the vehicle can go straight back to normal use. ## Once the fuel drain is done: driving in Finney Green once more - Drive normally. There is nothing special to do after it has been started on fresh fuel. - Keep an eye on the first miles. A warning light, smoke, a rough idle or a flat spot under your throttle means pull over and call us back. - Keep your paperwork. A hire company, a fleet manager or an insurer may ask what was carried out. - Next time, trust the pump's label rather than the colour of its handle. ## About Finney Green, briefly Finney Green is a suburban area in Cheshire, situated on the riverside with an elevation of 84 metres, and is located approximately 9.7 miles from Manchester.
