Engine off. Leave the car like that — no second on, no moving it anywhere. The coming few minutes decide it more than anything else: petrol in a diesel that has not run usually comes down to clearing then cleaning, on the spot. Here's the sequence of things from now, anywhere you're in Blunham. ## Motor off: minute one with petrol in a diesel Before anything else, the following — in this order. - Ignition off, keys out. Turned on, your ignition can prime your system — and priming is what moves petrol out of the tank into the parts it harms. - Topping up with diesel seems like it thins the issue. It doesn't: nothing comes out, and that tank just holds more of the same. - Hazards on. If you are anywhere close to moving traffic, make the vehicle simple to see before you do anything else. - The attendants will generally help you push it clear of the petrol pump. Ask, and roll it by hand — never on the motor, even for a couple of yards. - Which fuel, and about how much? Your receipt replies both, and that is where our questions start. Don't bin it. Still driving when you noticed? Come off the A1(M) at the next exit if that is where you are, under 15 miles from Blunham, and stop somewhere safe instead of pushing on to the services. Then start at step one. ## Each Blunham fuel drain starts here: has the motor run? One answer is what everything after this stage depends on. If it has not once been started: - All the petrol sits in that tank, and only there. - The work is a simple drain and a flush, normally done where the car is. - This is as good as it gets — which is the whole point of step one. Run at all, however briefly: - Petrol has been pulled from the tank, past the fuel filter then into your lines. - The high-pressure fuel pump as well as the injectors get it on a bigger run. - Flushing the lines, the fuel filter sorted, and sometimes more: this job expands as the distance does. Petrol does not lubricate. Diesel does, protecting the pump and injectors as it flows through, which is why the line falls where it does. Nothing is harmed by petrol that is only waiting in a tank. Pump that petrol, though, and it wears the very parts doing the moving. ## Calling about petrol in a diesel from Blunham: what to have prepared A technician that circles against a van that finds you: a little planning is the difference. - MK44 3 plus the rest of the postcode makes the ideal way to begin telling us where you are. - The street or the car park. A road name helps — The Hill, or wherever you have stopped. - Describe a car park by what it serves — the one outside Cooperative Food, for example — and it is far quicker to find. - Make and model of the vehicle, and the fact it is a diesel. - What was put in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Blunham, and so say which. - How much. Litres from the receipt, or how long the nozzle was in the filler. - If it has run, how far plus how heavily — as well as whether it has run at all. - Whose vehicle it is. Some hire and company contracts want the owner to approve the work, and that's easier settled before our technicians get there than after. Then phone 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — works too. ## Waiting for a fuel drain around Blunham: what to do The wait is where kindly meant help does the damage. Hold to these. - Your safety comes before the vehicle. Somewhere dangerous? Get away from the traffic then wait away from it. Fine where it is? Stay with 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 it gets the petrol back out — not two-stroke oil, not injector cleaner, not anything from your boot. So no additives. - A DIY drain misses the fuel already gone beyond your tank, and siphoning petrol by the road is hazardous besides. - Not for the radio, not for the windows: your ignition stays off. ## Van arrived? The fuel drain, one step at a time - Three questions. What went in, how much, and whether it has run. The replies set this job, which is why the quote comes after them and not before. - Out of the tank comes the contaminated mixture: the tank is cleared. - The lines are cleaned. If it ran, that petrol has moved beyond your tank, and the lines are holding it. - The fuel filter is dealt with. Cleared, or changed where your car has a workable one. - The system is primed with fresh diesel. - We start the engine only after clean diesel has gone in and primed your system, then confirm that it's running properly. Only once it's running on new diesel do our engineers leave. If it has been noticed quickly, permanent damage is very rare, and your car goes back to normal use straight away. ## Blunham, after your fuel drain: back on the road - Nothing unusual is needed after a start with clean diesel — normal driving is all. - Pull over and call 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. - The paperwork covers the query a rental company, fleet manager or insurer may ask: what work was carried out. Keep it. - The handle's colour is not the guide to go by next time — the label on the pump is. ## About Blunham, for a moment Blunham is a village in Bedfordshire, situated on the banks of the River Great Ouse at an elevation of around 26 metres.
