Pause; leave the vehicle off. Has not been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever your car has stopped — and nothing settles that as much as the next few minutes do. What follows is the sequence from this point, anywhere in Blashford you happen to be. ## Petrol in a diesel, motor off — the first minute In this order, all before anything else: - The ignition off, keys out. Switched on, your ignition can prime your system — and priming is what draws petrol out of your tank towards the parts it damages. - Topping up with diesel seems like it thins the trouble. It does not: nothing comes out, and your tank simply holds more of the same. - Get the vehicle simple to see first — hazards on — if there's traffic going past anywhere near you. - Off the pump by hand. On a forecourt, get the attendants to help you roll it clear of the petrol pump. Do not fire it up to shift it, however short the way. - The first question you will be asked is which fuel went in and roughly how much — and the receipt says both. Hold on to it. On the M27, under 10 miles from Blashford, the next junction is the place to come off; anywhere, the first sensible place to stop. Don't press on to the services. Then go back to step one. ## The fork in each Blashford fuel drain: has it run yet? One answer is what everything after this stage depends on. If the motor has not run at all: - No place but that tank: that's where the petrol yet is. - A drain and flush, on the spot, is normally the whole job. - Stage one matters for exactly this reason: it's the best place to be in. If the motor has been run, even for a moment: - Petrol has been drawn out of the tank, past your filter then into your lines. - A bigger run carries it right through to the high-pressure pump and your injectors. - Miles is what turns it into a bigger job: flushed lines, a filter seen to, and at times further work. The line falls there since diesel protects your high-pressure pump and the fuel injectors on its way through them — and petrol doesn't. In that tank, left alone, petrol harms nothing. The parts that move it are wearing the moment petrol is being pumped. ## Before you call about petrol in a diesel in Blashford: what our engineers need Get ready a little, and the van finds you rather than circling. - BH24 3 and the rest of the postcode is the best way to begin telling us where you are. - A road name helps: Salisbury Road, say, or whatever street you have stopped in. A car park does the trick too. - Car parks are located most easily by what they serve: say the one at Waitrose, and it is straightforward. - Tell us what the vehicle is — make, model — and check it is diesel. - Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has a separate Blashford page. - Roughly how much — in litres from your receipt, or by how long the nozzle was in. - If it's run, how far plus how hard — and whether it's run at all. - Whose vehicle it is. Some hire and company agreements want the owner to authorise the work, and that is easier settled before we get there than after. Call 0333 366 0103 then. Email works too if it can wait, with the vehicle left at home, going nowhere. ## While you wait for a fuel drain in Blashford Help, however well meant, is the thing that does the harm while you wait. So stick to these. - Stay with the vehicle if it's safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it. - No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll it a couple of yards. - None of that takes the petrol back out — not two-stroke oil, not injector cleaner, not anything from your boot. So no additives. - Draining it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and the fuel beyond that tank remains where it is all the same. - The ignition stays off. Even for your radio or your windows. ## When the van arrives: your fuel drain, step by step - Fuel, amount, whether it has run: the replies decide this job, and that's why you get a price after them rather than before. - Clearing it's how that blend gets taken from the tank. - Petrol that has moved beyond the tank travels in your lines once it ran, and the fuel lines are cleaned to clear it. - Your filter is sorted. Cleared, or changed where the car has a usable one. - Clean diesel goes in, then the fuel system is primed. - First start on new diesel. When priming is done, your engine is started and our engineers check that it runs properly. Our technicians remain until it is running on new diesel. If it has been caught quickly, long-term damage is very rare, and your car goes back to normal use right away. ## Blashford, after the fuel drain: back on the road - Nothing special is needed after a start with fresh diesel — usual driving will do. - Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or the throttle hesitating: pull over and ring us back. - An insurer, a fleet manager or a hire firm may ask what was carried out, and so keep your documents. - Next time, trust the pump's label instead of the colour of its handle. ## About Blashford, for a moment Blashford is a small village situated on the shores of Blashford Lakes in Hampshire, with a low elevation of around 24 metres.
