Here Is What Happens Pause, and leave the motor off — not on, and not for a moment to shift the vehicle. Drained then cleaned, just where it sits: that is usually all an unrun diesel with petrol in it takes. Whether it stays that simple depends on the minutes to come far more than on everything else. From now on, in order, for anywhere in Dunipace: ## Engine off: minute one with petrol in a diesel First, the following — following this order. - Priming the fuel system pulls petrol from your tank toward the components it harms, and switching the ignition on can be enough to do that. So your keys come out, and your ignition stays off completely. - Do not top it up with diesel. Adding diesel removes nothing. You are left with a bigger tank of the same mixture. - Visibility comes before the rest near moving traffic: switch your hazards on, and only then deal with everything else. - The attendants will generally help you push it clear of the pump. Ask, then roll it by hand — never under the engine, even for a couple of yards. - Keep the receipt. It says which fuel went in plus about how much, which is the first thing we'll ask. On the M80, under a mile from Dunipace, the next exit is the place to leave the vehicle; anywhere, the first sensible spot to stop. Don't press on to the services. Then go back to step one. ## The fork in every Dunipace fuel drain: has it run yet? Everything after this point rests on one answer. Motor never run at all? - All the petrol sits inside the tank, and only there. - The work is a drain and a flush, normally done where your car stands. - Step one matters for precisely this reason: it's the best place to be in. If the engine has been run, even briefly: - Petrol has been drawn from that tank, past the fuel filter then into your lines. - A longer run carries it right through to your high-pressure pump and the fuel injectors. - Distance is what makes it a bigger job: the lines flushed, a filter seen to, and at times further work. Why the line falls there: diesel protects the high-pressure pump as well as your injectors as it passes through them, and petrol does not. Petrol sitting in a tank harms nothing. The parts that move it are grinding the moment petrol is being pumped. ## What to have ready when you call about petrol in a diesel from Dunipace A little preparation is the difference between a van that finds you and a van that circles. - Your location: a postcode starting FK6 6 serves best. - The road or the car park. A road name is a help — Barnego Road, or wherever you have stopped. - Describe a car park by what it serves — the one outside The Co-operative Food, for example — and it's far quicker to find. - The make and model of the car, and the fact it is a diesel. - Which got in matters: AdBlue is a separate job from petrol, and Dunipace has a page just for that. So say. - How much. Litres from your receipt, or how long the nozzle was in the filler. - The distance it did, and how heavily, if it has run at all. - Hire or company car? Some agreements want the owner's go-ahead for the work, and getting it before our technicians arrive is quicker than afterwards. Then ring 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — works too. ## The wait for a Dunipace fuel drain, and what to do in it Stick to these: kindly meant help causes the damage during the wait. - Where your car has stopped decides where you wait. Somewhere exposed: away from it, clear of the traffic. Safe: with it. Either way, safety before the car. - 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. - Anything from the boot, oil made for two-strokes or injector cleaner: no additive removes that petrol. - Siphoning petrol into a can by the roadside is risky — and it also leaves whatever fuel has already gone beyond the tank. Do not try a home-made drain. - Even the radio or the windows are not worth switching your ignition on for. ## Step by step: the fuel drain when the van gets there - First, three queries: which fuel went in, the volume, and has it run? Those answers decide this job, and so our quote follows them. - Then your tank is cleared, and the contaminated fuel comes out. - If it ran, the fuel lines are holding petrol that has shifted beyond the tank — so they're flushed. - The fuel filter is seen to. Cleared, or replaced where your car has a workable one. - Fresh diesel goes in, and your system is primed. - Starting up. After the system is bled with fresh diesel, our engineers fire it up and check it runs correctly. Only once it is running on fresh diesel do our technicians leave. It is very rare for a vehicle caught early to be left with permanent damage, and normal driving starts again at once. ## Once the fuel drain is done: driving in Dunipace a second time - Once it's been started on fresh fuel, there is nothing special to do: drive normally. - Keep an eye on the first miles. A warning light, smoke, a rough idle or a flat spot under the throttle means pull over and ring us back. - The work may matter later with a hire firm, an insurer or a fleet manager. Hold on to your paperwork. - Next time, read the pump. The label, not the colour of the handle. ## About Dunipace, briefly Dunipace is a village situated on the banks of the River Carron in central Scotland, with a mix of terraced housing and other residential properties.
