Pause; leave it off. The next few minutes determine it more than anything else: petrol in a diesel still unrun usually comes down to clearing then rinsing, on the spot. From now on, in order, wherever you are around Newfield Green: ## Petrol in a diesel, engine off — the first minute First, these — in this sequence. - Bleeding the system pulls petrol from the tank toward the parts it damages, and switching your ignition on can be all it takes to do that. So your keys come out, and your ignition stays off completely. - No diesel on top. More fuel in removes none of the petrol — it just leaves you with extra of the same mixture. - Close to moving traffic? Then your hazards go on before everything else, and so the vehicle is easy to see. - By hand, not on your engine: that is how it leaves the petrol pump. Get the forecourt staff to help you push, whatever the mileage. - The first question we will ask is which fuel you put in and roughly how much — and the receipt says both. Keep it. Noticed on the move? Get off at the next junction if you're on the M1, under 5 miles from Newfield Green, and pull over somewhere sensible — not at the services further on. Stage one comes after that. ## Each Newfield Green fuel drain starts here: has your motor run? What happens next rests on one answer, and only one. Not run, not even once: - The petrol remains in the tank, and just there. - Where the car stands is usually where the work is done: a drain, then a flush. - Step one counts for precisely this reason: it is the best spot to be in. If the engine has run, even briefly: - From that tank, through the fuel filter, into the fuel lines: that's how far that petrol has travelled. - Run it further and the petrol gets to the fuel injectors, having passed through your pump first. - The job expands with the miles — lines rinsed, filter dealt with, occasionally more. Why the line falls there: diesel lubricates your high-pressure pump as well as the injectors as it flows through them, and petrol does not. In your tank, left alone, petrol does no harm. The components that shift it are wearing the moment petrol is being pumped. ## Calling about petrol in a diesel from Newfield Green: what to have prepared A technician that circles versus a van that finds you: a little preparation is the difference. - Your location: a postcode starting S2 2 works best. - Give the road — Gleadless Road or wherever you have stopped — or the car park. - Or the landmark. A car park is easier to find by what it serves, like the one at Heron Foods. - That it's a diesel, plus the make and model of the vehicle. - Which got in counts: AdBlue is a separate job from petrol, plus Newfield Green has a page for it. So say. - The amount: your receipt's litres, or else how long you held the nozzle in. - Has it run? If so, say how far it went, and the way it was driven. - The owner may have to approve this work under some hire or company agreements — so it is faster to settle whose car it is before our engineers get there. Call 0333 366 0103 once you have got that ready — or, if the vehicle is at home, going nowhere, use . ## While you wait for a fuel drain around Newfield Green The wait is where well-intended help does the harm. Stick to these. - Your safety comes before the car. Somewhere unsafe? Get away from the traffic and wait away from it. Safe where it is? Stay with it. - Nobody starts it. Not a passer-by being helpful, not to check it is all right, not to roll the vehicle a couple of yards. - No additives. Two-stroke oil, injector cleaner, anything from the boot — none of that gets that petrol back out. - No DIY clearing. Siphoning petrol into a can by the kerbside is dangerous, and it leaves the fuel that has by now gone beyond that tank. - Ignition stays off. Even for your radio or your windows. ## Van arrived? Your fuel drain, one stage at a time - Fuel, amount, whether it's run: the answers decide the job, and that's why we give a price after them rather than before. - Emptying it is how that blend gets taken out of that tank. - Cleaning the fuel lines comes next, since a car that ran has petrol past your tank, in your lines themselves. - Where the car has a usable filter, it's swapped; otherwise, cleared. - Bleeding the system follows once clean diesel is in. - Our engineers fire it up only after clean diesel has gone in and bled the fuel system, then check that it's running smoothly. Only once it's running on fresh diesel do we leave. Lasting damage is very uncommon if it has been noticed quickly, so the vehicle can go right back to normal driving. ## Back on the road in Newfield Green after the fuel drain - Nothing special is needed after a start with clean diesel — usual driving will do. - Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or your throttle hesitating: pull over and call us back. - Your paperwork answers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Next time, check the petrol pump. The label, not the colour of its handle. ## About Newfield Green itself Newfield Green is a suburban area located on the riverside in South Yorkshire, with a mix of residential flats and local amenities.
