The next few minutes determine it more than anything else: petrol in a diesel that has not run usually amounts to emptying and rinsing, on the spot. Wherever you are in Bonhard Terrace, this is how things run from here. ## Minute one: petrol in a diesel, engine off Do these before anything else, in this order. - Priming the system pulls petrol from the tank towards the components it damages, and switching the ignition on can be enough to do that. So the keys get taken out, and the ignition stays off completely. - Topping up with diesel seems like it thins the problem. It doesn't: nothing comes out, and your tank just holds more of the same. - Visibility comes before the rest beside moving traffic: switch the hazard lights on, and only then deal with everything else. - The staff will usually help you push it clear of the pump. Let them, and roll it by hand — not on your engine, even for a couple of yards. - Hold on to the till receipt. It shows which fuel was put in plus roughly how much, which is the first thing we'll ask. Noticed on the move? Get off at the next junction if you are on the M9, under 3 miles from Bonhard Terrace, and stop somewhere safe — not at the services farther on. Stage one comes after that. ## Has it run yet? The fork in each Bonhard Terrace fuel drain From this stage on, everything hinges on a single answer. If it has not once been started: - Only your tank has petrol in it for now. - The job is a drain and a flush, usually done where your car stands. - No position is better, and it is why the first step counts so much. Motor run, even briefly? - Petrol has been pulled out of your tank, past the filter then into your lines. - The high-pressure pump as well as the fuel injectors see it too on a bigger run. - The further it went, the larger the job — the fuel lines, your filter, and sometimes more besides. That line falls there since diesel lubricates the high-pressure fuel pump and the fuel injectors on its way through them — and petrol doesn't. Nothing is harmed by petrol that's only waiting in a tank. Petrol being pumped is grinding down the components that shift it. ## What to have ready when you call about petrol in a diesel from Bonhard Terrace Get ready a little, and the technician finds you rather than circling. - EH51 9 and the remainder of the postcode makes the best way to start telling us where you are. - A road name helps: Borrowstoun Road, say, or whatever street you have stopped in. A car park works too. - Or the landmark. A car park is easier to find by what it serves, such as the one at Scotmid. - Make and model of the car, and the fact it's a diesel. - Petrol or AdBlue? Say which. They are different jobs, and AdBlue has a separate Bonhard Terrace page. - Roughly how much — in litres from the receipt, or by how long the nozzle was in. - Has it run? If so, say how far it got, and the way it was driven. - Settle who owns the car before our engineers turn up: some hire and company agreements want the owner to approve this work, and that is quicker beforehand. Ring 0333 366 0103 then. Writing to is fine as well if it can wait, with your car parked at home, going nowhere. ## Waiting for a fuel drain around Bonhard Terrace: what to do Help, however well meant, is what does the harm whilst you wait. So hold to these. - Stay with your car if it's safe where it is — but if it has stopped somewhere dangerous, you come first: away from the traffic, waiting apart from it. - Not to roll it a few yards, not to check it is all right, not as a passer-by's kindness: no one starts it. - None of it takes the petrol back out — not two-stroke oil, not injector cleaner, not anything from the boot. So no additives. - No home-made clearing. Siphoning petrol into a can by the kerbside is risky, and it leaves your fuel that has already gone beyond that tank. - The ignition stays off. Even for your radio or the windows. ## Step by step: the fuel drain when our van arrives - Our quote comes after three queries, not before them — what went in, how much, and whether it's run — because the answers set the job. - Draining it's how the blend gets taken out of that tank. - Purging the fuel lines follows, because a vehicle that ran has petrol past your tank, inside the fuel lines themselves. - Cleared, or replaced if your car has a serviceable one: the filter is dealt with next. - Your system is primed with clean diesel. - The start. With new diesel in and the fuel system bled, it is fired up and tested to make sure it runs correctly. Only when it's running on clean diesel do we go. It is very rare for a car caught quickly to be left with lasting damage, and normal use starts again right away. ## Bonhard Terrace, after the fuel drain: back on the road - Started on new diesel, it asks nothing unusual of you. Simply drive normally. - Pull over and ring us back if anything seems wrong early on — a light on the dash, smoke from the exhaust, an idle that runs rough, or a throttle with a dead spot. - Hold on to your paperwork. A hire company, a fleet manager or an insurer may ask what was done. - Next time, read the pump. The label, not the colour of its handle. ## About Bonhard Terrace and where it is Bonhard Terrace is a locality situated near the coast in Falkirk, with an elevation of 78 metres and a mix of detached housing.
