Here Is What Happens Stop. Motor off. Keep it that way — no second on, no shifting it anywhere. Petrol in a diesel that hasn't been run is typically a simple drain and a flush, done where your car stands, and what you do in the coming few minutes settles that more than anything else. Wherever you happen to be in Washgreen, this is the order things run from now. ## Engine off: minute one with petrol in a diesel Work through the following in order, before you do anything else. - The ignition off, keys out. Turned on, your ignition can prime the system — and priming is what draws petrol out of your tank towards the parts it harms. - Do not top it up with diesel. Adding diesel removes nothing. You are left with a fuller tank of the same mix. - Being seen comes first beside moving traffic: switch the hazard lights on, and only then deal with everything else. - However short the way, starting it to move it is the thing to avoid. At a forecourt, push it away from the pump by hand instead, and ask the staff to help. - Which fuel, and about how much? The receipt answers both, and that is where our first question starts. Never throw it away. Noticed on the move? Get off at the next junction if you're on the M1, under 10 miles from Washgreen, and stop somewhere sensible — not at the services further on. Stage one starts after that. ## Has it run yet? The fork in every Washgreen fuel drain From this stage on, everything hinges on a single answer. If it has never been started: - The petrol sits inside that tank, and only there. - Normally it's drained and purged just where the car stands. - This, here, is the best position to be in, and the reason stage one counts. If your engine has run, even for a moment: - The fuel lines and the fuel filter now carry petrol pulled out of that tank. - On a longer run it has reached the high-pressure fuel pump and the fuel injectors. - The job expands with the mileage — lines purged, filter dealt with, occasionally more. Petrol doesn't lubricate. Diesel does, protecting your pump and injectors as it flows through, which is why the line sits where it does. In the tank, left alone, petrol does no harm. Petrol being pumped is wearing the parts that shift it. ## Before you call about petrol in a diesel around Washgreen: what our technicians need A technician that circles versus a technician that finds you: a little planning is what separates them. - The best place to start is a postcode — one starting DE4 4 — for where you are. - A road name is a help: Nether Mill Court, say, or whichever street you've stopped in. A car park does the trick too. - What a car park serves is the easiest way to find it, so say the landmark — such as the one outside Sainsbury's. - The make and model of your vehicle, and the fact it's a diesel. - What was put in. Petrol, or AdBlue. AdBlue is a different job with its own page for Washgreen, and so say which. - How much. Litres from your receipt, or how long the nozzle was in the filler. - Has it run? If so, say how far it went, and how it was driven. - Sort who has your car before our engineers arrive: some hire and company agreements want the owner to authorise this work, and that is faster beforehand. Call 0333 366 0103 once you've got that ready — or, if the vehicle is at home, going nowhere, use . ## The wait for a Washgreen fuel drain, and what to do in it The wait is where kindly meant help does the harm. Hold to these. - Stay with your car if it's safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it. - A helpful passer-by does not start it. Nor does anybody wanting to check it still does the trick, or moving it a few yards. - Anything from your boot, oil meant for two-strokes or injector cleaner: no additive removes that petrol. - A home-made drain misses the fuel that has already gone beyond your tank, and siphoning petrol by the road is hazardous too. - Ignition remains off. Even for the radio or the windows. ## The fuel drain, step by step, once the van arrives - Fuel, amount, whether it's run: the answers decide the job, and that's why we give a price after them rather than before. - That tank is emptied. The tainted mix comes from that tank. - Cleaning the fuel lines follows, since a motor that ran has petrol past that tank, inside the fuel lines themselves. - The filter is sorted. Cleared, or swapped where the vehicle has a workable one. - The system is primed on fresh diesel. - First start on new diesel. Once priming is finished, the motor is started and we check that it runs smoothly. Only once it is running on clean diesel do our technicians head off. Long-term damage is very unusual when it has been caught early, so the car can go straight back to normal driving. ## After the fuel drain is done: driving in Washgreen a second time - Started on new diesel, it asks nothing special of you. Just drive normally. - Keep an eye on 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. - Your documents answers the query a rental company, fleet manager or insurer may ask: what work was carried out. Keep it. - Next time, read the pump. The label, not the colour of its handle. ## About Washgreen and where it is Washgreen is a suburban area situated on the riverside in Derbyshire, with an elevation of around 200 metres.
