Motor off. Keep the vehicle like that — no moment on, no moving it at all. Hasn't been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever the vehicle has stopped — and no other factor decides that more than these next few minutes do. Here is the order of things from here, wherever you're in Chingford Green. ## Motor off: minute one with petrol in a diesel First, the following — in this sequence. - Ignition off, keys out. Turned on, your ignition can prime your system — and priming is what draws petrol out of the tank towards the components it damages. - Don't top it up with diesel. Adding diesel removes nothing. You end up with a fuller tank of the same mixture. - Visibility comes before the rest beside moving traffic: switch your hazards on, and only then deal with everything else. - Off the petrol pump by hand. At a forecourt, get the attendants to help you push it away from the pump. Do not fire it up to move it, however short the way. - The first question you will be asked is which fuel you put in and about how much — and the till receipt says both. Keep it. If you were still driving when you realised, stop somewhere sensible rather than pushing on for the services — on the M11, under 3 miles from Chingford Green, that means the next exit. Stage one follows. ## Chingford Green fuel drain: has your motor run yet, or not? What comes after this turns on one answer, and just one. Motor never run at all? - The petrol remains inside the tank, and only there. - Where the car sits is normally where the work happens: a drain, then a flush. - Being here is the best case — which is the entire point of step one. If the motor has run, even for a moment: - The lines and the fuel filter now hold petrol drawn out of that tank. - A longer run carries it all the way to the high-pressure fuel pump and the fuel injectors. - The job grows with the mileage — lines flushed, filter dealt with, occasionally more. Diesel keeps the high-pressure fuel pump and the injectors protected as it runs through them. Petrol offers them nothing, and that's why the line is drawn there. Petrol sitting in a tank harms nothing. Pump that petrol, though, and it wears the very parts that move it. ## Chingford Green, petrol in a diesel: have these prepared before you call Get ready a little, and the van finds you rather than circling. - Your location: a postcode beginning E4 6 serves best. - A road name is a help: Nation Way, say, or whichever street you've stopped in. A car park does the trick too. - Car parks are found most easily by what they serve: say the one outside Co-op Food, and it's straightforward. - The make and model of the car, and the fact it's a diesel. - Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has its own Chingford Green page. - How long the nozzle was in, or the litres from your receipt — either gives us how much. - Has it run? If so, tell us how far it got, and how it was driven. - Hire or company car? Some contracts want the owner's authorisation for this work, and sorting it before we turn up is faster than afterwards. Next, 0333 366 0103. Not urgent, your car left at home with nowhere to be? Then works too. ## The wait for a Chingford Green fuel drain, and what to do in it Help, however well meant, is the thing that does the damage whilst you wait. So stick to these. - Your safety comes before your car. Somewhere unsafe? Get away from the traffic and wait away from it. Safe where it stands? Stay with it. - No one — however kind — starts it, whether to see if it runs or to shift your car a short way. - Additives stay in the boot. Injector cleaner and two-stroke oil take none of the petrol out once more. - A home-made drain leaves the fuel already gone beyond that tank, and siphoning petrol by the road is risky besides. - Not for your radio, not for your windows: the ignition remains off. ## The fuel drain, step by step, once our van arrives - Our price comes after three queries, not before them — what went in, how much, and whether it has run — since those replies shape the job. - The tank is cleared. The tainted mixture comes out of that tank. - The lines are purged. If it ran, the petrol has moved beyond the tank, and your lines are holding it. - Where the vehicle has a usable filter, it is changed; if not, cleared. - Fresh diesel in, and the fuel system primed. - First start on clean diesel. Once priming is done, the motor is started and our technicians check that it runs smoothly. The vehicle has fresh diesel running through it before we head off. If it has been noticed quickly, permanent damage is very unusual, and your car goes back to normal use right away. ## After your fuel drain: back on the road in Chingford Green - Drive normally. There is nothing special to do after it's been started on fresh fuel. - Watch the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle means pull over then ring us back. - The work may matter later with a hire firm, an insurer or a fleet manager. Keep the paperwork. - Next time, check the pump. The label, not the colour of the handle. ## About Chingford Green itself Chingford Green is a suburban area in Greater London, situated approximately 10 miles northeast of central London.
