Pause; leave the vehicle off. Emptied and rinsed, just where it is: that is usually all an unrun diesel with petrol in it takes. Whether it stays that straightforward depends on the minutes to come far more than on everything else. From now on, step by step, for anywhere in Littlemoor: ## Minute one: petrol in a diesel, motor off In this sequence, and before everything else: - The keys out of the ignition. Switching your ignition on can be all it takes to prime the system, while priming pulls petrol out of the tank toward the parts it harms. Keep the car off altogether. - Don't top it up with diesel. Adding diesel takes out nothing. You are left with a bigger tank of the same mixture. - Make your car easy to see before anything else — hazards on — if there is moving traffic anywhere near you. - By hand, never under the motor: that is how it leaves the petrol pump. Get the forecourt attendants to help you roll, however short the mileage. - The first question we will ask is which fuel you put in and roughly how much — and the receipt shows both. Keep it. Still on the move when you noticed? Come off the M5 at the next junction if that is where you are, under 50 miles from Littlemoor, and pull over somewhere sensible rather than pressing on to the services. Then begin at step one. ## The fork in each Littlemoor fuel drain: has it run yet? From this point on, everything comes down to a single answer. If your engine hasn't run at all: - The petrol sits in the tank, and only there. - The work is a simple drain and a flush, usually done where the car stands. - This is the best place to be in, and the reason stage one counts. Engine run, however for a moment? - The fuel lines and the filter already carry petrol pulled from that tank. - The high-pressure pump and the injectors see it too on a bigger run. - Miles is what turns it into a larger job: the lines flushed, a filter seen to, and at times further work. Petrol does not lubricate. Diesel does, oiling the pump and injectors as it flows through, which is why the line falls where it does. In that tank, left alone, petrol harms nothing. As soon as it's pumped, petrol starts grinding whatever moves it. ## What to have ready when you call about petrol in a diesel from Littlemoor A little planning is the difference between a van that finds you and a technician that circles. - Where you have stopped. A postcode starting DT3 6 is the best place to start. - Name the street — Littlemoor Road or wherever you have stopped — or the car park. - Name a car park by what it serves — the one outside Morrisons, for example — and it is much easier to find. - The car. Make, model, and that it is a diesel. - Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has its own Littlemoor page. - How much. Litres from your receipt, or how long the nozzle was in the filler. - If it's run, how far and how heavily — and if it's run at all. - Hire or company car? Some contracts need the owner's authorisation for the work, and getting it before our engineers arrive is faster than after. Then phone 0333 366 0103. If it can wait — your car is at home with going nowhere — does the trick too. ## Littlemoor fuel drain on its way? While you wait Help, however well meant, is the thing that does the harm while you wait. So stick to these. - Wait with the car 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. - A helpful passer-by does not start it. Nor does anybody checking it still does the trick, or rolling it a couple of yards. - No additives. Two-stroke oil, injector cleaner, anything from your boot — none of that gets that petrol back out. - Emptying it yourself is out: a can of siphoned petrol on a verge is a danger, and the fuel beyond that tank stays put all the same. - Keep your ignition off — your windows and the radio too. ## Van arrived? Your fuel drain, one stage at a time - Our quote comes after three questions, not before them — what got in, how much, and whether it's run — because the replies decide this job. - Out of that tank comes the tainted blend: the tank is cleared. - Your lines are cleaned. If it ran, the petrol has moved beyond the tank, and the lines are carrying it. - Then the filter: changed where there is a usable one, cleared where there is not. - Fresh diesel goes in, then the fuel system is primed. - Starting up. When your system is bled with fresh diesel, we fire it up and make sure it runs properly. Until it runs on clean diesel, our engineers stay with it. It's very unusual for a car noticed quickly to be left with long-term damage, and normal use starts again straight away. ## Back on the road around Littlemoor after your fuel drain - Started on fresh diesel, it needs nothing unusual of you. Simply drive normally. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your signal to stop then ring us a second time. - Your documents answers the query a rental company, fleet manager or insurer may ask: what work was carried out. Keep it. - Next time, trust the petrol pump's label instead of the colour of its handle. ## About Littlemoor and where it is Littlemoor is a coastal suburban area in Dorset, situated near the towns of Weymouth and Portland, and close to the nearby places of Broadwey, Bincombe, and Redlands.
