Drained and flushed, just where it sits: that is usually all an unrun diesel with petrol in it takes. Whether it remains that straightforward depends on the minutes to come more than on anything else. Below is the sequence from this point, wherever in Millbank you happen to be. ## Motor off: minute one with petrol in a diesel Work through these in sequence, before you do anything else. - Bleeding your fuel system pulls petrol from your tank towards the parts it damages, and turning your ignition on can be all it takes to do that. So your keys get taken out, and the ignition stays off altogether. - Topping up with diesel sounds like it thins the problem. It doesn't: nothing comes out, and the tank just carries more of the same. - Close to moving traffic? Then the hazard lights go on before anything else, and so the car is easy to spot. - The attendants will generally help you push it clear of the petrol pump. Let them, and roll it by hand — not under your engine, even for a couple of yards. - Keep your receipt. It says which fuel got in plus about 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 M77, over 50 miles from Millbank, and pull over somewhere safe — not at the services farther on. Step one starts after that. ## The fork in every Millbank fuel drain: has it run yet? From this stage on, everything comes down to a single answer. Motor never run at all? - Nowhere but your tank: that is where the petrol still is. - The job is a drain and a flush, usually done where your car stands. - No position is better, and it's why the first step matters so much. Engine run, however briefly? - From the tank, past the fuel filter, into your lines: that is how far the petrol has got. - A bigger run carries it right through to your high-pressure pump and the fuel injectors. - Mileage is what turns it into a larger job: flushed lines, a filter seen to, and at times more than that. Diesel keeps the high-pressure pump and the injectors oiled as it goes through them. Petrol offers them nothing, and that's why the line is drawn there. A tank of petrol, left still, damages nothing. Once it is pumped, petrol begins grinding whatever moves it. ## What to have prepared when you call about petrol in a diesel from Millbank Whether the van goes round or finds you depends on a little planning. - Where you have stopped. A postcode beginning BT36 8 is the ideal place to start. - A road name is a help: Chalet Road, say, or whichever street you have stopped in. A car park works too. - What a car park serves is the quickest way to find it, so say the landmark — like the one at the local shops. - The car. Make, model, plus that it is a diesel. - Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has its own Millbank page. - How much. Litres from your receipt, or how long the nozzle was in. - The distance it covered, and how heavily, if it has run at all. - Sort who owns the car ahead of when we arrive: some hire or company contracts want the owner to authorise this work, and that is faster beforehand. Then call 0333 366 0103. If it can wait — the car is at home with going nowhere — works as well. ## Millbank fuel drain on its way? While you wait During the wait, the damage comes from well-meant help — which is why these count. - Your safety comes before the car. Somewhere dangerous? Get clear of the traffic then wait away from it. Safe where it sits? Wait with it. - Not to roll it a couple of yards, not to check it is all right, not for a passer-by's kindness: no one starts it. - None of it 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 roadside is risky — and it still leaves whatever fuel has already gone beyond that tank. Do not try a home-made drain. - Not for your radio, not for the windows: the ignition stays off. ## Van arrived? The fuel drain, one step at a time - First, three questions: which fuel got in, the amount, and has it run? Those answers set the job, and so our quote follows them. - The tank is emptied. The polluted blend comes out of the tank. - If it ran, your lines are holding petrol that has shifted beyond the tank — so they are cleaned. - The filter is sorted. Cleared, or replaced where the car has a serviceable one. - Fresh diesel in, and the fuel system primed. - The first start on new diesel. Once priming is finished, your engine is started and we check that it runs correctly. Only when it's running on fresh diesel do our engineers leave. Long-term damage is very uncommon if it has been spotted soon, so the car can go straight back to normal driving. ## After your fuel drain: back on the road in Millbank - Nothing unusual is needed after a start with clean diesel — ordinary driving will do. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your signal to stop and ring us once more. - The documents answers the question a rental company, fleet manager or insurer may ask: what work was carried out. Keep it. - Read the label on the petrol pump next time, not the colour of the handle. ## About Millbank, for a moment Millbank is a locality in County Antrim, situated inland at an elevation of 107 metres, approximately 8 miles northwest of Belfast.
