Stop; leave the car off. Has not been run? Then petrol in a diesel tends to be a straightforward drain-and-flush job wherever the vehicle has stopped — and no other factor decides that more than these next few minutes do. From here on, in order, for anywhere around Holt End: ## Minute one: petrol in a diesel, motor off In this sequence, all before everything else: - Priming the fuel system draws petrol from your tank toward the parts it harms, and switching your ignition on can be enough to do that. So the keys come out, and your ignition stays off completely. - A bigger tank of the same mixture is all topping up leaves you, because it takes out nothing. So no more diesel. - Make your car easy to see before anything else — hazards on — if there is traffic going past anywhere close to you. - By hand, not under your engine: that is how it comes off the petrol pump. Ask the forecourt attendants to help you push, however short the distance. - Hold on to your 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 exit if you're on the M3, under 10 miles from Holt End, and stop somewhere sensible — not at the services further on. Step one starts after that. ## Has it run yet? The fork in every Holt End fuel drain From this stage on, everything comes down to a single answer. Not run, not even once: - The petrol is still inside your tank and nowhere else. - The job is a simple drain and a flush, normally done where your car is. - Being here is as good as it gets — which is the whole point of stage one. If it has been started, even for a moment: - Your lines and the fuel filter now hold petrol drawn from your tank. - Run it farther and that petrol gets to the fuel injectors, having passed through your pump first. - The further it went, the larger the job — the fuel lines, your filter, and sometimes more besides. Diesel keeps the high-pressure fuel pump and the injectors lubricated as it runs through them. Petrol gives them nothing, and that's why the line is drawn there. Petrol sitting in a tank damages nothing. The components that move it are wearing the moment petrol is being pumped. ## Calling about petrol in a diesel from Holt End: what to have ready A little preparation is the difference between a van that finds you and a technician that goes round. - Where you are. A postcode starting GU34 5 is the ideal place to start. - Wherever you have pulled up, the road's name helps — whether that's Holt End Lane or somewhere else — and so does the name of a car park. - Name a car park by what it serves — the one at M&S Foodhall, for example — and it's much quicker to find. - Say what your car is — make, model — and confirm it is diesel. - What got in. Petrol, or AdBlue. AdBlue is a different job with its own page for Holt End, and so say which. - How long the nozzle was in, or the litres from your receipt — whichever gives us how much. - Whether it's run. And if it has, how far plus how heavily. - Hire or company car? Some agreements need the owner's authorisation for this work, and sorting it before we turn up is faster than afterwards. Call 0333 366 0103 once you have got that together — or, if your car is at home, going nowhere, use . ## Waiting for a fuel drain around Holt End: what to do 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 then wait away from it. Fine where it sits? Wait with it. - A helpful passer-by doesn't crank it. Nor does anyone wanting to check it still works, or moving it a few yards. - Additives remain in the boot. Injector cleaner and two-stroke oil draw none of the petrol out a second time. - A home-made drain leaves the fuel already gone beyond your tank, and siphoning petrol by the road is dangerous besides. - Even your radio or the windows aren't worth turning the ignition on for. ## Van arrived? The fuel drain, one step at a time - Fuel, amount, whether it has run: the replies decide the job, and that's why you get a price after them instead of before. - The tank is emptied. The tainted mixture comes from your tank. - Petrol that has moved beyond the tank travels in the lines if it ran, and the lines are cleaned to clear it. - Cleaned, or changed if the car has a workable one: your filter is sorted next. - The system is primed on fresh diesel. - The start. With new diesel in and the system bled, it's started and checked to be sure it runs properly. We remain until it's running on new diesel. Lasting damage is very rare if it has been caught quickly, so the car can go right back to normal driving. ## After the fuel drain: back on the road around Holt End - After it's been started on clean fuel, there's 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 signal to stop then ring us again. - The paperwork answers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Next time, check the pump. The label, not the colour of its handle. ## About Holt End Holt End is a small hamlet in Hampshire, situated inland at an elevation of 186 metres, approximately 12.5 miles from Winchester.
