Petrol in a diesel that has not been run is normally a drain plus a flush, done right where the car sits, and what happens in the coming few minutes settles that more than anything else. From now on, in order, for anywhere around Columbia Farm: ## Petrol in a diesel, motor off — the first minute In this sequence, and before anything else: - Priming the fuel system draws petrol from the tank towards the parts it damages, and switching your ignition on can be enough to do that. So the keys get taken out, and your ignition stays off altogether. - Topping up with diesel seems like it dilutes the issue. It does not: nothing gets out, and the tank just holds more of the same. - Hazards on. If you are at all near moving traffic, make the car simple to see before you do anything else. - Off the pump by hand. On a forecourt, get the staff to help you roll the car clear of the pump. Don't start it to move it, however short the distance. - Keep your receipt: the fuel and roughly how much are printed on it, and they're what we ask for first. On the M27, under 25 miles from Columbia Farm, the next junction is the place to leave the vehicle; anywhere, the first sensible spot to stop. Do not push on to the services. Then go back to step one. ## Columbia Farm fuel drain: has the engine run yet, or not? What happens after this rests on one answer, and only one. If it has not once been started: - The petrol remains inside that tank, and just there. - Where your car stands is usually where the work is done: a drain, then a flush. - No position is better, and it's why the first step counts so much. Run at all, however briefly: - From that tank, past the filter, into the lines: that is how far the petrol has got. - The high-pressure pump and the fuel injectors see it too on a longer run. - The further it went, the bigger this job — your lines, the filter, and now and then more besides. That line falls there since diesel protects the high-pressure pump and your injectors on its way through them — and petrol does not. Petrol sitting in a tank harms nothing. The parts that shift it are wearing the moment petrol is being pumped. ## What to have prepared when you call about petrol in a diesel from Columbia Farm A little preparation is the difference between a technician that finds you and a van that circles. - BH10 4 and the remainder of the postcode is the best way to begin telling us where you are. - A road name is a help: Talbot Rise, say, or whatever street you have stopped in. A car park does the trick too. - Car parks are located more easily by what they serve: tell us the one outside The Co-operative Food, and it's simple. - Say what the vehicle is — make, model — and check it is diesel. - Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has its own Columbia Farm page. - About how much — in litres from the receipt, or by how long the nozzle stayed in. - The mileage it covered, and how hard, if it ran at all. - Sort who has your car before we arrive: some hire or company contracts want the owner to approve this work, and doing it quicker beforehand. Call 0333 366 0103 then. Writing to is fine as well if it can wait, with the car parked at home, going nowhere. ## Whilst you wait for a fuel drain around Columbia Farm Help, however well meant, is what does the damage whilst you wait. So stick to these. - Your safety comes before the car. Somewhere unsafe? Get clear of the traffic then wait away from it. Fine where it stands? Stay with it. - A helpful passer-by does not crank it. Nor does anybody wanting to check it still works, or rolling it a few yards. - Additives stay in your boot. Injector cleaner and two-stroke oil take none of that petrol out a second time. - A home-made drain misses the fuel that has already gone beyond the tank, and siphoning petrol by the road is hazardous too. - The ignition stays off. Even for the radio or the windows. ## When the van arrives: your fuel drain, step by step - Our quote comes after three queries, not before them — what got in, how much, and whether it's run — since the answers decide the job. - Next your tank is emptied, and the contaminated fuel comes out. - Cleaning the fuel lines follows, since a car that ran has petrol past the tank, in your lines themselves. - The fuel filter is dealt with. Cleared, or replaced where the vehicle has a usable one. - Clean diesel goes in, then your system is primed. - Our technicians fire it up only after fresh diesel has gone in and bled the fuel system, then check that it is running smoothly. Our technicians stay until it's running on new diesel. The car returns to normal driving at once, and permanent damage is very uncommon when it has been spotted quickly. ## Columbia Farm, after your fuel drain: back on the road - Nothing unusual is needed after a start with fresh diesel — usual driving is all. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your cue to stop and call us a second time. - Your documents covers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Read the label on the petrol pump next time, not the colour of its handle. ## About Columbia Farm itself Columbia Farm is a suburban area in Dorset, situated near the coast and characterised by detached housing.
