Engine off. Leave the car like that — no second on, no shifting it at all. The next few minutes decide it far more than anything else: petrol in a diesel still unrun usually amounts to clearing and rinsing, right there. Here is the order of things from now, anywhere you're around Heathfield. ## Petrol in a diesel? What to do in minute one Go through the following in order, before you do anything else. - Priming the fuel system draws petrol from your tank toward the parts it harms, and switching your ignition on can be all it takes to do that. So your keys get taken out, and your ignition remains off altogether. - Topping up with diesel seems like it dilutes the problem. It doesn't: nothing comes out, and that tank just holds more of the same. - Get the vehicle simple to see before anything else — hazards on — if there is traffic going past anywhere close to you. - The attendants will normally help you push it away from the pump. Let them, then roll it by hand — never on the motor, even for a couple of yards. - The first thing you will be asked is which fuel went in and roughly how much — and the till receipt says both. Hold on to it. On the M77, under 15 miles from Heathfield, the next exit is the spot to come off; elsewhere, the first sensible place to stop. Do not press on to the services. Then go back to step one. ## Has it run yet? The fork in every Heathfield fuel drain What happens next turns on one answer, and only one. If your engine hasn't run at all: - All the petrol remains in your tank, and just there. - Normally it is drained and cleaned just where your car stands. - No position is better, and it is why the first stage matters so much. Run at all, however briefly: - The lines and the fuel filter already hold petrol drawn from that tank. - Run it further and the petrol gets to your injectors, having passed through the pump first. - The job grows with the mileage — lines purged, filter sorted, occasionally more. Petrol doesn't lubricate. Diesel does, protecting the high-pressure pump and injectors as it passes through, which is why the line falls where it does. In your tank, sitting still, petrol harms nothing. Petrol being pumped is grinding down the parts that move the car. ## Calling about petrol in a diesel from Heathfield: what to have ready Whether the technician goes round or finds you comes down to a little planning. - The best start is a postcode — one starting KA8 9 — for where you have stopped. - The street or the car park. A road name helps — Boundary Road, or wherever you have stopped. - Car parks are found most easily by what they serve: tell us the one at Asda, and it is easy. - The car. Make, model, plus that it is a diesel. - Tell us which went in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Heathfield. - About how much — in litres from the receipt, or by how long the nozzle stayed in. - If it has run, how far plus how heavily — and whether it's run at all. - Whose car it is. Some hire or company contracts want the owner to approve this work, and that is quicker settled before our technicians get there than after. Ring 0333 366 0103 once you've got that ready — or, if the car is at home, going nowhere, use . ## Whilst you wait for a fuel drain around Heathfield In the wait, the harm comes from well-meant help — so these matter. - Safety before your car. If it has stopped somewhere exposed, get yourself clear of the traffic and wait away from it. If it's safe where it sits, stay with it. - No one — however kind — starts it, whether to see if it runs or to shift the vehicle a short way. - Additives stay in the boot. Injector cleaner and two-stroke oil take none of the petrol out a second time. - Siphoning petrol into a can by the kerbside is risky — and it still leaves whatever fuel has already gone beyond that tank. Do not drain the vehicle yourself. - Not for your radio, not for your windows: your ignition stays off. ## Van arrived? The fuel drain, one stage at a time - Three questions. What got in, how much, and whether it's run. The replies set the job, which is why the quote comes after them but not before. - Next your tank is emptied, so the tainted fuel is taken out. - Flushing the lines comes next, because a car that ran has petrol past the tank, in the fuel lines themselves. - Where your car has a workable filter, it's changed; if not, cleared. - The system is primed with fresh diesel. - Our engineers start the car only after new diesel has gone in and bled the system, then check that it is running properly. Until it runs on fresh diesel, our technicians remain with it. Permanent damage is very uncommon when it has been caught quickly, so the vehicle can go right back to normal use. ## Once the fuel drain is done: driving in Heathfield a second time - Drive normally. There is nothing special to do once it has been started on fresh fuel. - Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle means pull over then call us back. - Keep the paperwork. A hire firm, a fleet manager or an insurer may ask what was carried out. - Next time, go by the pump's label instead of the colour of its handle. ## About Heathfield Heathfield is a suburban area in South Ayrshire, situated near the coast at a low elevation of around 14 metres.
