Pause; leave the vehicle off. Petrol in a diesel that has not been run is normally a simple drain and a flush, done where your vehicle stands, and what happens in the next few minutes decides that more than anything else. What follows is the sequence from this point, anywhere around Leytonstone you are. ## Petrol in a diesel? What to do in minute one In this order, and before anything else: - The keys out of the ignition. Turning the ignition on can be all it takes to prime the system, while priming draws petrol out of your tank towards the components it harms. Keep it off completely. - Do not top it up with diesel. Adding diesel removes nothing. You end up with a bigger tank of the same mixture. - Near moving traffic? Then the hazard lights go on before everything else, and so the vehicle is simple to see. - However short the way, starting it to move it is the mistake. On a forecourt, roll it clear of the petrol pump by hand instead, then ask the attendants to help. - Hold on to the till receipt. It shows which fuel got in plus roughly how much, which is the first thing we'll ask. Realised on the move? Get off at the next junction if you're on the M11, under 3 miles from Leytonstone, and pull over somewhere sensible — not at the services further on. Stage one starts after that. ## Has it run yet? The fork in each Leytonstone fuel drain From this stage on, everything hinges on a single answer. If it has never been started: - No place but the tank: that's where that petrol still is. - The job is a simple drain and a flush, usually done where the vehicle is. - Step one matters for precisely this reason: it's the best position to be in. If the motor has been run, even for a moment: - From your tank, past the fuel filter, into your lines: that is how far the petrol has travelled. - The high-pressure pump as well as the injectors get it on a longer run. - Miles is what makes it a bigger job: flushed lines, a filter seen to, and at times more than that. Petrol does not lubricate. Diesel does, protecting your pump and injectors as it flows through, which is why the line falls where it does. Nothing is damaged by petrol that's only waiting in a tank. The parts that shift it are wearing the moment petrol is being pumped. ## Before you call about petrol in a diesel in Leytonstone: what our technicians need Whether the technician circles or finds you comes down to a little planning. - Where you have stopped. A postcode starting E11 1 is the best start. - The road or the car park. A road name helps — Kingswood Road, or wherever you have stopped. - What a car park serves is the quickest way to find it, and so mention the landmark — like the one at Aldi. - Tell us what your vehicle is — make, model — and check it's diesel. - Which went in matters: AdBlue is a separate job from petrol, plus Leytonstone has a page just for that. So tell us. - The amount: the receipt's litres, or else how long you had the nozzle in. - Whether it has run. Then if it has, how far plus how hard. - Whose vehicle it is. Some hire or company agreements want the owner to approve the work, and that's easier settled before our technicians turn up than after. Call 0333 366 0103 then. Writing to works too if it can wait, with your car parked at home, going nowhere. ## The wait for a Leytonstone fuel drain, and what to do in it The wait is where well-meant help does the damage. Hold to these. - Your safety comes before your car. Somewhere dangerous? Get clear of the traffic then wait away from it. Fine where it stands? Stay with it. - Nobody — however kind — starts it, whether to see if it runs or to shift your car a short way. - No additives. Two-stroke oil, injector cleaner, anything from the boot — none of that takes that petrol back out. - Draining it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond that tank stays where it is all the same. - Keep the ignition off — the windows and the radio too. ## Van arrived? The fuel drain, one step at a time - Three queries. What went in, how much, and if it has run. The replies set the job, which is why the price comes after them but not before. - The tank is drained. The tainted mix comes from your tank. - If it ran, the fuel lines are carrying petrol that has shifted beyond your tank — so they are rinsed. - Then your filter: changed where there's a usable one, cleared where there's not. - Priming follows after fresh diesel is in. - Our engineers fire it up only after fresh diesel has gone in and bled the system, then check that it's running smoothly. We stay until it is running on new diesel. The vehicle returns to normal driving right away, and lasting damage is very unusual when it has been caught quickly. ## After the fuel drain: back on the road in Leytonstone - After it's been started on clean fuel, there is nothing special to do: drive normally. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a hesitant throttle is your cue to stop then call us a second time. - An insurer, a fleet manager or a hire company may ask what was done, and so keep your paperwork. - Next time, trust the pump's label instead of the colour of its handle. ## About Leytonstone Leytonstone is a suburban area in east London, situated approximately 7.2 miles from central London and 5.8 miles from the city.
