Stop; leave the car off. Petrol in a diesel that has not been run is generally a drain and a flush, done where the car sits, and what you do in the coming few minutes settles that far more than anything else. Wherever you happen to be around Antonshill, this is the order things run from here. ## Petrol in a diesel, motor off — the first minute Before anything else, these — in this order. - The ignition off, keys out. Switched on, the ignition can prime your system — and priming is what draws petrol out of your tank into the components it harms. - Topping up with diesel seems like it dilutes the problem. It doesn't: nothing gets out, and that tank simply carries more of the same. - Close to passing traffic? Then the hazard lights come on before everything else, so your car is easy to spot. - By hand, never on the engine: that's how it leaves the pump. Get the forecourt staff to help you push, whatever the distance. - Hold on to your receipt: the grade and the rough amount are written on it, and they're what our engineers ask for first. On the M9, under a mile from Antonshill, the next exit is the location to leave the vehicle; elsewhere, the first safe location to stop. Do not press on to the services. Then go back to stage one. ## Every Antonshill fuel drain starts here: has your engine run? One answer is what everything after this point depends on. Not run, not even briefly: - Just your tank has petrol in it for now. - Normally it's drained and purged right where the vehicle stands. - This is the best case — which is the whole point of step one. Motor run, however for a moment? - Petrol has been pulled from your tank, past the fuel filter then into the lines. - The high-pressure pump as well as the fuel injectors get it on a longer run. - The farther it went, the larger the job — the lines, the filter, and sometimes more besides. Petrol doesn't lubricate. Diesel does, protecting the high-pressure pump and injectors as it flows through, which is why the line sits where it does. A tank of petrol, left still, damages nothing. Pump that petrol, though, and it grinds down the very parts that move it. ## Before you call about petrol in a diesel around Antonshill: what our technicians need Prepare a little, and the technician finds you instead of circling. - FK5 4 plus the rest of the postcode makes the best way to start telling us where you are. - Give the street — Hamilton Road or wherever you have stopped — or the car park. - Describe a car park by what it serves — the one at Asda, for instance — and it's much easier to find. - The car. Make, model, plus that it's a diesel. - Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has its own Antonshill page. - How long the nozzle was in, or the litres on the receipt — whichever gives us how much. - The miles it did, and how heavily, if it ran at all. - Whose vehicle it is. Some hire and company contracts want the owner to authorise this work, and that's quicker settled before we turn up than after. Ring 0333 366 0103 next. Writing to is fine as well if it can wait, with your car left at home, going nowhere. ## The wait for a Antonshill fuel drain, and what to do in it During the wait, the damage comes from well-meant help — so these matter. - Where your car has stopped settles where you wait. Exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety ahead of your car. - No one — however kind — starts it, whether to see if it runs or to shift the vehicle a short way. - Something from the boot, oil made for two-strokes or injector cleaner: no additive removes that petrol. - Siphoning petrol into a can at the kerbside is hazardous — and it still leaves whatever fuel has already gone beyond the tank. Don't try a home-made drain. - Not for the radio, not for your windows: your ignition remains off. ## The fuel drain, step by step, once our van gets there - The price comes after three queries, not before them — what was put in, how much, and if it has run — because those replies set this job. - That tank is drained. The polluted mixture comes from your tank. - Flushing the fuel lines comes next, because a car that ran has petrol past the tank, in the lines themselves. - Then the fuel filter: replaced where there is a serviceable one, cleared where there is not. - Priming follows once clean diesel is in. - The start. With clean diesel in and your system bled, it is started and checked to be sure it runs smoothly. Only once it is running on fresh diesel do our technicians go. When it has been spotted quickly, permanent damage is very uncommon, and your car returns to normal driving at once. ## Antonshill, after your fuel drain: back on the road - Nothing special is needed after a start with clean diesel — normal driving will do. - Give the first miles your attention. Smoke showing, a warning light coming on, your idle going lumpy or the throttle stumbling: pull over and call us back. - An insurer, a fleet manager or a hire firm may ask what was carried out, and so hold on to your documents. - Read the label on the petrol pump next time, not the colour of its handle. ## About Antonshill itself Antonshill is a suburban area situated on the riverside in Falkirk, with a mix of housing types but predominantly detached homes.
