Here Is What Happens Not for a second, and not for moving it: the motor remains off. Pause there. Emptied then flushed, right where it sits: that's usually all an unrun diesel with petrol in it takes. Whether it stays that simple rests on the minutes ahead far more than on anything else. From now on, step by step, wherever you are in Birdham: ## Petrol in a diesel? What to do in minute one First, the following — in this sequence. - Bleeding the system draws petrol from the tank towards the parts it damages, and switching your ignition on can be enough to do that. So your keys come out, and your ignition stays off completely. - A fuller tank of the same mixture is all topping up gives you, because it takes out nothing. So no extra diesel. - Being seen comes before the rest beside moving traffic: put your hazards on, and only then think about anything else. - Off the pump by hand. On a forecourt, get the staff to help you push it away from the pump. Do not start the vehicle to shift it, however short the way. - Which fuel, and about how much? Your receipt replies that, and that is where our questions start. Don't bin it. Noticed on the move? Get off at the next junction if you are on the Waterlooville Bypass, under 10 miles from Birdham, and pull over somewhere safe — not at the services farther on. Stage one starts after that. ## Has it run yet? The fork in every Birdham fuel drain From this point on, everything hinges on a single answer. If your engine has not run at all: - That petrol is still in that tank and nowhere else. - Where the car sits is usually where the work is done: a drain, then a flush. - This is the best position to be in, and the whole reason stage one counts. Engine run, however briefly? - Petrol has been drawn out of your tank, through your filter and into the fuel lines. - On a bigger run it has got to your high-pressure pump as well as the injectors. - The farther it went, the larger this job — the lines, your filter, and sometimes more besides. Petrol doesn't lubricate. Diesel does, oiling the pump and injectors as it flows through, which is why the line sits where it does. In your tank, left alone, petrol does no harm. As soon as it's pumped, petrol begins wearing down whatever moves it. ## Calling about petrol in a diesel from Birdham: what to have ready Get ready a little, and the technician finds you instead of circling. - Where you are. A postcode beginning PO20 7 is the ideal place to start. - A road name is a help: The Saltings, say, or whatever street you've stopped in. A car park does the trick too. - Describe a car park by what it serves — the one at Tesco Extra, for instance — and it's far quicker to find. - The vehicle. Make, model, and that it's a diesel. - Tell us which was put in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Birdham. - How much. Litres from the receipt, or how long the nozzle was in the filler. - If it has run, how far plus how heavily — and if it has run at all. - Whose vehicle it is. Some hire or company contracts want the owner to approve the work, and that is quicker settled before our technicians get there than after. Then ring 0333 366 0103. If it can wait — the vehicle is at home with going nowhere — works too. ## The wait for a Birdham fuel drain, and what to do in it Help, however well meant, is the thing that does the damage whilst you wait. So stick to these. - Safety before your car. If it has stopped somewhere dangerous, get yourself away from the traffic then wait away from it. If it's safe where it is, wait with it. - No one starts it. Not a passer-by being kind, not to check it is all right, not to roll it a couple of yards. - No additives. Two-stroke oil, injector cleaner, anything from the boot — none of that takes the petrol back out. - Clearing it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and the fuel beyond your tank stays where it is all the same. - The ignition remains off. Even for your radio or your windows. ## Van arrived? The fuel drain, one step at a time - Fuel, quantity, whether it's run: the answers set this job, and that is why we give a quote after them instead of before. - Draining it is how that mixture gets taken out of the tank. - Petrol that has moved beyond the tank sits in the lines once it ran, and the lines are rinsed to clear it. - Where the vehicle has a serviceable filter, it is changed; otherwise, cleared. - Priming follows once clean diesel is in. - Our technicians start the engine only after clean diesel has gone in and bled the fuel system, then check that it's running correctly. Only once it is running on fresh diesel do our technicians go. It is very rare for a vehicle spotted soon to be left with permanent damage, and normal driving resumes straight away. ## Once the fuel drain is done: driving around Birdham a second time - Nothing unusual is needed after a start with clean diesel — ordinary driving is all. - Keep an eye on the first miles. A warning light, smoke, a rough idle or a flat spot under your throttle means pull over and ring us back. - The paperwork covers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it. - The handle's colour is not the guide to go by next time — the label on the petrol pump is. ## About Birdham and where it is Birdham is a small coastal village in West Sussex, situated near the city of Chichester and close to the neighbouring communities of Westlands and Somerley.
