Here Is What Happens Whatever you do, don't switch your engine on, even briefly, to shift the vehicle. Pause; leave it off. Has not been run? Then petrol in a diesel will usually be a simple drain-and-flush job wherever your vehicle has stopped — and nothing decides that more than these next few minutes do. Here is the sequence of things from now, wherever you're around Chigwell. ## Motor off: minute one with petrol in a diesel In this sequence, and before everything else: - Pull your keys out. Even the ignition by itself can prime the fuel system, pulling petrol out of your tank to exactly the components it harms, and so keep it off wholly. - No diesel on top. More fuel in takes away none of that petrol — it just makes you with extra of the same blend. - Close to passing traffic? Then your hazards go on before anything else, and so the car is simple to spot. - By hand, not under your engine: that's how it leaves the petrol pump. Ask the forecourt staff to help you push, whatever the distance. - Keep the receipt: the fuel and roughly how much are written on it, and they are what our technicians ask for first. Still driving when you noticed? Come off the M11 at the next junction if that is where you are, under a mile from Chigwell, and stop somewhere safe rather than pressing on to the services. Then begin at step one. ## The fork in every Chigwell fuel drain: has it run yet? What comes after this rests on one answer, and just one. Not run, not even briefly: - That petrol is still in your tank and nowhere else. - Draining and flushing, on the spot, is normally all of that. - This is as good as it gets — which is the whole point of step one. If the engine has been run, even briefly: - Some petrol has left the tank by now, gone through the filter, and got into your lines. - Run it farther and that petrol reaches your injectors, having passed through your pump first. - The farther it went, the larger the job — the lines, the fuel filter, and sometimes more besides. The reason the line falls there: diesel lubricates your high-pressure pump and the injectors as it passes through them, and petrol does not. Petrol resting in a tank harms nothing. Petrol being pumped is grinding down the components that move it. ## Before you call about petrol in a diesel around Chigwell: what our engineers need Get ready a little, and the van finds you rather than circling. - IG7 6 and the remainder of the postcode is the ideal way to start telling us where you are. - Wherever you have pulled up, the road's name is useful — whether that's High Road or somewhere else — and so does the name of a car park. - Or the nearest landmark. A car park is quicker to find by what it serves, like the one outside Lidl. - That it is a diesel, plus the make and model of the car. - What got in. Petrol, or AdBlue. AdBlue is a different job with its own page for Chigwell, and so tell us which. - The quantity: the receipt's litres, or else how long you held the nozzle in. - The mileage it covered, and how heavily, if it has run at all. - Hire or company car? Some agreements want the owner's go-ahead for the work, and sorting it before our technicians arrive is faster than afterwards. Ring 0333 366 0103 next. Email works too if it can wait, with the vehicle parked at home, going nowhere. ## Waiting for a fuel drain in Chigwell: what to do Help, however well meant, is what does the damage while you wait. So stick to these. - Safety before the car. If it has stopped somewhere dangerous, get yourself clear of the traffic then wait away from it. If it is safe where it is, stay with it. - A kind passer-by does not crank it. Nor does anyone checking it still works, or rolling it a couple of yards. - None of that takes the petrol back out — not two-stroke oil, not injector cleaner, not something from the boot. So no additives. - Siphoning petrol into a can at the kerbside is dangerous — and it also leaves whatever fuel has already gone beyond the tank. Don't try a home-made drain. - Even the radio or the windows are not worth switching your ignition on for. ## Van arrived? The fuel drain, one step at a time - First, three questions: which fuel went in, the quantity, and has it run? Those answers decide this job, so the price follows them. - Next your tank is cleared, so the polluted fuel comes out. - The fuel lines are cleaned. If it ran, that petrol has shifted beyond your tank, and the fuel lines are carrying it. - Then the fuel filter: replaced where there's a serviceable one, cleared where there's not. - Bleeding the system comes once clean diesel is in. - The first start on fresh diesel. When bleeding is complete, your engine is fired up and our engineers make sure that it runs correctly. Till it runs on clean diesel, our technicians stay with it. It's very unusual for a vehicle noticed soon to be left with permanent damage, and normal use starts again straight away. ## After the fuel drain is done: driving around Chigwell once more - After it has been started on fresh fuel, there's nothing unusual to do: drive normally. - Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or the throttle stumbling: pull over and call us back. - An insurer, a fleet manager or a hire company may ask what was carried out, and so keep your paperwork. - Read the label on the pump next time, not the colour of the handle. ## About Chigwell, briefly Chigwell is a town in Essex, situated on the River Roding at an elevation of around 39 metres, with a mix of rural and urban landscapes.
