Emptied and flushed, just where it sits: that is normally all an unrun diesel with petrol in it needs. Whether it remains that straightforward rests on the minutes to come more than on everything else. From now on, step by step, for anywhere in Braithwell: ## Petrol in a diesel? What to do in minute one First, the following — in this sequence. - Keys out of the ignition. Switching the ignition on can be all it takes to prime your fuel system, while priming pulls petrol out of the tank toward the parts it damages. Keep the car off completely. - Do not top it up with diesel. Adding diesel takes out nothing. You end up with a bigger tank of the same mixture. - Make your car easy to see before anything else — hazard lights on — if there is moving traffic anywhere close to you. - The attendants will usually help you roll it clear of the petrol pump. Let them, and move it by hand — not under the engine, even for a few yards. - Hold on to the receipt: the fuel and roughly how much are written on it, and they are what our engineers ask for first. Realised on the move? Get off at the next junction if you're on the M18, under a mile from Braithwell, and stop somewhere safe — not at the services further on. Step one starts after that. ## Each Braithwell fuel drain starts here: has the motor run? One answer is what everything after this point rests on. Not run, not even once: - Nowhere but your tank: that's where that petrol yet is. - The job is a drain and a flush, usually done where your car stands. - This is the best spot to be in, and the reason step one counts. If it has been started, even for a moment: - The fuel lines and your filter now carry petrol pulled from your tank. - A longer run takes it right through to your high-pressure pump and the fuel injectors. - The further it went, the larger the job — the fuel lines, the filter, and sometimes more besides. Diesel keeps your high-pressure pump and the fuel injectors lubricated as it goes through them. Petrol offers them nothing, and that's why the line is drawn there. In the tank, sitting still, petrol does no harm. Move that petrol, though, and it grinds down the very parts that move it. ## Calling about petrol in a diesel from Braithwell: what to have prepared Whether the van goes round or finds you depends on a little preparation. - Your whereabouts: a postcode beginning S66 7 works best. - Name the street — Church Grove or wherever you have stopped — or the car park. - Or the landmark. A car park is easier to find by what it serves, like the one outside Heron Foods. - Tell us what the vehicle is — make, model — and confirm it's diesel. - What got in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Braithwell, and so tell us which. - How much. Litres from your receipt, or how long the nozzle was in. - Whether it has run. Then if it has, how far and how heavily. - The owner may have to authorise the work under some hire or company agreements — so it is quicker to settle whose car it is before we arrive. Ring 0333 366 0103 once you've got that ready — or, if the vehicle is at home, going nowhere, use . ## While you wait for a fuel drain in Braithwell 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. - Nobody — however kind — starts it, whether to see if it runs or to shift the car a short way. - None of that takes the petrol back out — not two-stroke oil, not injector cleaner, not anything from your boot. So no additives. - A home-made drain misses your fuel already gone beyond the tank, and siphoning petrol by the road is risky besides. - Not for your radio, not for your windows: your ignition stays off. ## Van arrived? The fuel drain, one step at a time - Fuel, volume, whether it's run: those answers decide the job, and that is why we give a quote after them rather than before. - Out of that tank comes the contaminated mix: the tank is emptied. - If it ran, your lines are carrying petrol that has moved beyond that tank — so they're cleaned. - Cleared, or changed if the car has a serviceable one: your filter is sorted next. - Clean diesel goes in, then the fuel system is primed. - Starting up. Once your system is primed with clean diesel, our engineers start the engine and check it runs properly. The vehicle has clean diesel running through it before we go. The car goes back to normal driving at once, and long-term damage is very uncommon when it has been spotted quickly. ## Braithwell, after the fuel drain: back on the road - Started on clean diesel, it asks nothing special of you. Just drive normally. - Pull over and ring us back if anything seems wrong early on — a light on your dash, smoke from the exhaust, an idle that runs rough, or a throttle with a dead spot. - An insurer, a fleet manager or a hire company may ask what was carried out, and so hold on to the paperwork. - The handle's colour isn't the guide to go by next time — the label on the pump is. ## About Braithwell itself Braithwell is a small village in South Yorkshire, situated approximately 6 miles from Doncaster and 141 miles from London.
