Stop there. The next few minutes determine it far more than anything else: petrol in a diesel still unrun normally comes down to draining then purging, right there. Below is the order from here, wherever around Locking Castle you are. ## Petrol in a diesel? What to do in minute one Work through these first, in this sequence. - Priming your fuel system draws petrol from your tank toward the components it damages, and turning the ignition on can be all it takes to do that. So the keys get taken out, and the ignition stays off completely. - A bigger tank of the same mix is all adding diesel gives you, because it takes out nothing. So no more diesel. - Make your car easy to see first — hazards on — if there's traffic going past anywhere close to you. - The attendants will usually help you push it clear of the pump. Let them, then move it by hand — never on your engine, even for a couple of yards. - Hold on to the till receipt: the grade and the rough amount are written on it, and they are what our technicians ask about first. Noticed on the move? Get off at the next exit if you are on the M5, under a mile from Locking Castle, and stop somewhere sensible — not at the services further on. Step one comes after that. ## The fork in each Locking Castle fuel drain: has it run yet? From this stage on, everything comes down to a single answer. If your motor has not run at all: - No place but your tank: that's where that petrol still is. - Where your car sits is usually where this work happens: a drain, then a flush. - No position is better, and it's why the first step counts so much. If it has been started, even for a second: - Petrol has been drawn from your tank, past the filter and into your lines. - The high-pressure pump and the injectors get it on a longer run. - Mileage is what makes it a larger job: the lines flushed, a filter seen to, and at times further work. Petrol does not lubricate. Diesel does, protecting your high-pressure pump and injectors as it flows through, which is why the line sits where it does. A tank of petrol, left still, damages nothing. Once it's pumped, petrol begins wearing down whatever moves it. ## What to have ready when you call about petrol in a diesel from Locking Castle Whether the van circles or finds you comes down to a little planning. - The ideal start is a postcode — one starting BS24 7 — for where you are. - Give the road — Summer Lane or wherever you have stopped — or the car park. - Or the nearest landmark. A car park is easier to find by what it serves, such as the one at Morrisons. - Say what your car is — make, model — and confirm it is diesel. - What went in. Petrol, or AdBlue. AdBlue is a different job with its own page for Locking Castle, and so tell us which. - How long the nozzle was in, or the litres from your receipt — either gives us how much. - Whether it's run. And if it has, how far plus how hard. - Hire or company car? Some agreements need the owner's go-ahead for this work, and getting it before we get there is faster than afterwards. Call 0333 366 0103 then. Email works too if it can wait, with the vehicle parked at home, going nowhere. ## The wait for a Locking Castle fuel drain, and what to do in it Stick to these: well-intended help causes the harm during the wait. - Your safety comes before the car. Somewhere exposed? Get away from the traffic and wait away from it. Fine where it sits? Stay with it. - Nobody — however helpful — starts it, whether to see if it runs or to shift your car a short way. - None of it takes the petrol back out — not two-stroke oil, not injector cleaner, not anything from the boot. So no additives. - A home-made drain misses the fuel that has already gone beyond the tank, and siphoning petrol by the road is dangerous besides. - Even the radio or the windows aren't worth switching your ignition on for. ## When our van arrives: your fuel drain, step by step - First, three queries: which fuel got in, the quantity, and has it run? Those replies decide the job, so the price follows them. - Clearing it's how the mixture gets taken out of that tank. - Petrol that has shifted beyond your tank sits in the lines if it ran, and the lines are purged to clear it. - Your filter is sorted. Cleared, or swapped where the car has a usable one. - Priming comes after clean diesel is in. - We fire it up only after fresh diesel has gone in and bled your system, then check that it is running properly. Our technicians wait until it's running on new diesel. It's very uncommon for a car spotted soon to be left with permanent damage, and normal driving resumes right away. ## Once the fuel drain is done: driving around Locking Castle once more - Drive normally. There's nothing special to do after it has been started on fresh fuel. - Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or the throttle hesitating: pull over then call us back. - Hold on to the paperwork. A hire company, a fleet manager or an insurer may ask what was done. - Next time, check the pump. The label, not the colour of the handle. ## About Locking Castle, for a moment Locking Castle is a suburban area in Somerset, situated near the coast and close to the nearby places of West Wick, Worle, and St Georges.
