Here Is What Happens Whatever you do, don't switch the motor on, even briefly, to move it. Stop; leave the vehicle off. Hasn't been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever the vehicle has stopped — and no other factor decides that as much as these next few minutes do. Wherever you happen to be in Shawfield, this is how things go from now. ## Petrol in a diesel? What to do in minute one Before anything else, the following — in this order. - Bleeding your fuel system pulls petrol from the tank toward the components it damages, and switching your ignition on can be all it takes to do that. So your keys come out, and your ignition stays off completely. - A bigger tank of the same mix is all topping up gives you, since it takes out nothing. So no extra diesel. - Near moving traffic? Then your hazards come on before anything else, and so the car is easy to spot. - The attendants will generally help you roll it away from the pump. Ask, then roll it by hand — never on your engine, even for a few yards. - Hold on to the till receipt. It shows which fuel got in and about how much, which is the first thing we'll ask. If you were still driving when you realised, pull over somewhere sensible instead of pushing on for the services — on the M74, under a mile from Shawfield, that means the next junction. Step one comes next. ## The fork in each Shawfield fuel drain: has it run yet? From this stage on, everything comes down to a single answer. If your engine has not run at all: - No place but the tank: that's where the petrol still is. - Normally it's drained and rinsed just where your car stands. - Being here is the best case — which is the whole point of stage one. Motor run, even briefly? - Petrol has been drawn from the tank, through your filter then into the lines. - A longer run carries it all the way to the high-pressure pump and the injectors. - The job grows with the mileage — lines cleaned, filter seen to, sometimes more. That line falls there since diesel protects the high-pressure fuel pump and your injectors on its way through them — and petrol doesn't. Petrol resting in a tank harms nothing. The components that shift it are wearing the moment petrol is being pumped. ## Shawfield, petrol in a diesel: have these prepared before you call Prepare a little, and the technician finds you instead of circling. - Where you are. A postcode beginning G5 0 is the best place to start. - The road or the car park. A road name helps — Glasgow Road, or wherever you have stopped. - What a car park serves is the quickest way to find it, and so say the landmark — such as the one outside Tesco Extra. - The make and model of your vehicle, and the fact it is a diesel. - Petrol or AdBlue? Say which. They are different jobs, and AdBlue has a separate Shawfield page. - How much. Litres from the receipt, or how long the nozzle was in the filler. - The distance it did, and how hard, if it has run at all. - Whose motor it is. Some hire or company contracts want the owner to authorise this work, and that's quicker settled before we get there than after. Call 0333 366 0103 once you've got that ready — or, if the vehicle is at home, going nowhere, use . ## Shawfield fuel drain on its way? Whilst you wait Hold to these: well-meant help does the damage during the wait. - Safety before your car. If it has stopped somewhere exposed, get yourself away from the traffic then wait away from it. If it's safe where it stands, wait with it. - Not to roll it a couple of yards, not to check it is all right, not for a passer-by's favour: nobody starts it. - Additives stay in your boot. Injector cleaner and two-stroke oil draw none of the petrol out again. - Clearing it yourself is out: a can of siphoned petrol on a verge is a danger, and the fuel beyond your tank remains put regardless. - Not for the radio, not for your windows: the ignition stays off. ## Step by step: your fuel drain when our van gets there - Three queries. What got in, how much, and if it's run. The answers set this job, which is why our price comes after them and not before. - Out of your tank comes the polluted blend: the tank is emptied. - Petrol that has shifted beyond that tank travels in the lines if it ran, and your lines are rinsed to shift it. - Then the fuel filter: replaced where there's a serviceable one, cleared where there's not. - Fresh diesel goes in, then the system is primed. - Starting the car. After the fuel system is primed with clean diesel, we fire it up and make sure it runs properly. The car has clean diesel running through it before we go. If it has been spotted quickly, permanent damage is very rare, and the car returns to normal use at once. ## Back on the road in Shawfield after your fuel drain - Started on fresh diesel, it needs nothing unusual of you. Just drive normally. - Pull over and call us back if anything looks wrong early on — a light on your dash, smoke from the exhaust, an idle that runs rough, or a throttle with a dead spot. - Your paperwork answers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it. - Next time, read the pump. The label, not the colour of its handle. ## About Shawfield itself Shawfield is a suburban area located on the riverside in South Lanarkshire, with a low elevation of around 8 metres.
