Here Is What Happens Stop. Motor off. Leave it like that — no moment on, no shifting it anywhere. Petrol in a diesel that has not been run is normally a simple drain and a flush, done right where the vehicle sits, and what you do in the coming few minutes settles that far more than anything else. Below is the sequence from this point, anywhere around West Knighton you are. ## Minute one: petrol in a diesel, engine off In this sequence, and before everything else: - Take the keys out. Even your ignition by itself can prime the fuel system, drawing petrol out of your tank to precisely the parts it damages, so keep it alone completely. - A fuller tank of the same mixture is all adding diesel leaves you, because it removes nothing. So no extra diesel. - Make your car easy to see first — hazard lights on — if there's traffic going past anywhere near you. - The attendants will generally help you push it clear of the petrol pump. Let them, and move it by hand — not on the engine, even for a couple of yards. - Which fuel, and about how much? Your receipt answers that, and that's where our first question starts. Don't bin it. If you were still driving when you noticed, stop somewhere safe instead of pushing on for the services — on the M1, under 5 miles from West Knighton, that means the next junction. Step one comes next. ## The fork in every West Knighton fuel drain: has it run yet? From this point on, everything hinges on a single answer. Engine never run at all? - All the petrol sits inside your tank, and just there. - Normally it is emptied and rinsed just where the car is. - No spot is better, and it is why the first step counts so much. If the motor has been run, even briefly: - From your tank, through the filter, into the fuel lines: that is how far the petrol has got. - The high-pressure fuel pump and the injectors see it too on a longer run. - The farther it went, the larger the job — the fuel lines, your filter, and now and then more besides. That line falls there because diesel lubricates your high-pressure pump and the injectors on its way through them — and petrol doesn't. Petrol resting in a tank damages nothing. The components that shift it are wearing the moment petrol is being pumped. ## Before you call about petrol in a diesel in West Knighton: what our engineers need Get ready a little, and the technician finds you instead of circling. - The ideal place to start is a postcode — one starting LE2 6 — for where you have stopped. - The road or the car park. A road name is a help — Aberdale Road, or wherever you have pulled up. - What a car park serves is the quickest way to find it, so say the landmark — such as the one outside West Knighton Supermarket. - Say what your vehicle is — make, model — and confirm it is diesel. - What went in. Petrol, or AdBlue. AdBlue is a separate job with its own page for West Knighton, so tell us which. - The quantity: your receipt's litres, or else how long you had the nozzle in. - Has it run? If so, tell us how far it went, and the way it was driven. - The owner may have to authorise this work under some hire and company contracts — which is why it's quicker to settle whose car it is before our technicians arrive. Then ring 0333 366 0103. If it can wait — the vehicle is at home with going nowhere — does the trick too. ## Waiting for a fuel drain in West Knighton: what to do The wait is where well-intended help does the harm. Stick to these. - Your safety comes before the car. Somewhere exposed? Get clear of the traffic and wait away from it. Safe where it sits? Stay with it. - A helpful passer-by does not start it. Nor does anyone checking it still does the trick, or moving it a couple of yards. - No additives. Two-stroke oil, injector cleaner, something from your boot — none of that takes that petrol back out. - Siphoning petrol into a can at the kerbside is hazardous — and it also leaves whatever fuel has already gone beyond the tank. Don't drain the vehicle yourself. - Even your radio or the windows are not worth switching the ignition on for. ## Van arrived? The fuel drain, one step at a time - First, three questions: which fuel got in, the quantity, and has it run? Those answers decide the job, and so the price follows them. - Out of that tank comes the tainted mix: that tank is cleared. - Petrol that has moved beyond that tank travels in the lines once it ran, and the lines are rinsed to clear it. - Where your car has a usable filter, it's changed; otherwise, cleared. - Fresh diesel goes in, then your system is primed. - The start. With fresh diesel in and the fuel system bled, it's fired up and checked to make sure it runs smoothly. Only when it's running on new diesel do our engineers leave. If it has been caught soon, lasting damage is very uncommon, and the vehicle returns to normal driving at once. ## West Knighton, after the fuel drain: back on the road - Drive normally. There is nothing special to do after it's been started on clean fuel. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your signal to stop then ring us again. - The paperwork covers the question a rental company, fleet manager or insurer may ask: what work was carried out. Keep it. - Next time, read the petrol pump. The label, not the colour of its handle. ## About West Knighton and where it is West Knighton is a suburban area located on the outskirts of Leicester, situated near the River Soar in the East Midlands region of England.
