Here Is What Happens Stop. Motor off. Leave it that way — no second on, no shifting it anywhere. Cleared and flushed, just where it sits: that is normally all an unrun diesel with petrol in it needs. Whether it remains that straightforward rests on the minutes to come more than on anything else. Here's the sequence of things from here, wherever you're around Benchill. ## Engine off: minute one with petrol in a diesel Work through these in sequence, first. - Bleeding the system draws petrol from your tank toward the parts it harms, and switching your ignition on can be all it takes to do that. So the keys come out, and your ignition stays off completely. - No diesel on top. More fuel in takes away none of the petrol — it only leaves you with more of the same blend. - Hazard lights on. If you are anywhere near moving traffic, make the car simple to see before you do anything else. - Off the petrol pump by hand. On a forecourt, ask the staff to help you push the car away from the petrol pump. Do not crank it to move it, however short the distance. - The first question you will be asked is which fuel you put in and roughly how much — and the till receipt says both. Keep it. Noticed on the move? Get off at the next junction if you are on the M56, under a mile from Benchill, and stop somewhere safe — not at the services farther on. Step one starts after that. ## Benchill fuel drain: has your engine run yet, or not? From this stage on, everything hinges on a single answer. Motor never run at all? - All the petrol remains inside your tank, and only there. - Draining and flushing, on the spot, is usually all of it. - Step one counts for exactly this reason: it's the best spot to be in. Run at all, even for a second: - Some petrol has left your tank already, passed through the filter, and reached the fuel lines. - The high-pressure pump as well as the fuel injectors see it too on a bigger run. - Lines flushed, the filter sorted, and sometimes more: this job expands as the mileage does. Petrol does not lubricate. Diesel does, oiling your pump and injectors as it passes through, which is why the line sits where it does. Nothing is damaged by petrol that's only sitting in a tank. The parts that move it are grinding the moment petrol is being pumped. ## What to have ready when you call about petrol in a diesel from Benchill Whether the van circles or finds you comes down to a little preparation. - The ideal place to start is a postcode — one starting M22 9 — for where you have stopped. - A road name helps: Broadoak Road, say, or whichever street you have stopped in. A car park does the trick too. - Name a car park by what it serves — the one at Nisa Local, for example — and it is much quicker to find. - Tell us what the vehicle is — make, model — and confirm it is diesel. - Which got in counts: AdBlue is a separate job from petrol, and Benchill has a page for it. So say. - How long the nozzle was in, or the litres on your receipt — whichever gives us how much. - If it's run, how far and how hard — as well as if it's run at all. - Whose motor it is. Some hire or company contracts want the owner to approve this work, and that is easier settled before we arrive than after. Call 0333 366 0103 then. Email works too if it can wait, with your car parked at home, going nowhere. ## Benchill fuel drain on its way? While you wait Hold to these: well-meant help does the harm during the wait. - Stay with the 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. - A helpful passer-by does not crank it. Nor does anyone wanting to check it still works, or moving it a few yards. - No additives. Two-stroke oil, injector cleaner, anything from your boot — none of it gets the petrol back out. - A home-made drain misses your fuel already gone beyond the tank, and siphoning petrol by the road is dangerous too. - Ignition stays off. Even for your radio or the windows. ## When the van arrives: your fuel drain, step by step - Fuel, volume, whether it's run: the answers set the job, and that's why you get a price after them rather than before. - Then your tank is emptied, so the tainted fuel comes out. - Cleaning the fuel lines comes next, because a motor that ran has petrol past the tank, in your lines themselves. - Then the filter: changed where there is a serviceable one, cleared where there is not. - Priming comes once fresh diesel is in. - The first start on clean diesel. When priming is done, your engine is fired up and our engineers confirm that it runs correctly. Until it runs on fresh diesel, we stay with it. If it has been caught quickly, permanent damage is very rare, and the vehicle goes back to normal driving right away. ## Once the fuel drain is done: driving around Benchill once more - Nothing special is needed after a start with fresh diesel — normal driving will do. - Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or your throttle stumbling: pull over and call us back. - The work may matter later with a hire company, an insurer or a fleet manager. Keep your documents. - Next time, check the pump. The label, not the colour of its handle. ## About Benchill Benchill is a suburban area in Greater Manchester, situated near the River Mersey at an elevation of around 55 metres.
