The next few minutes decide it far more than anything else: petrol in a diesel still unrun normally comes down to emptying and cleaning, right there. From now on, step by step, for anywhere around Clachnaharry: ## Motor off: minute one with petrol in a diesel Work through these first, in this sequence. - Keys out of your ignition. Turning the ignition on can be enough to prime the fuel system, while priming pulls petrol out of your tank towards the components it harms. Leave the car off completely. - No diesel on top. More fuel in removes none of the petrol — it just leaves you with extra of the same mixture. - Make the car easy to see before anything else — hazards on — if there is moving traffic anywhere near you. - The staff will normally help you push it away from the petrol pump. Let them, then move it by hand — never under the motor, even for a couple of yards. - Hold on to the till receipt: the grade and the rough amount are printed on it, and they are what our engineers ask for first. Realised on the move? Get off at the next exit if you're on the M90, over 50 miles from Clachnaharry, and pull over somewhere sensible — not at the services further on. Step one comes after that. ## Clachnaharry fuel drain: has the motor run yet, or not? One answer is what everything after this stage depends on. Not run, not even briefly: - That petrol is still in that tank and nowhere else. - Where the vehicle stands is normally where this work happens: a drain, then a flush. - This is the best position to be in, and the reason stage one counts. Run at all, even for a second: - From the tank, past the filter, into the fuel lines: that is how far the petrol has got. - Run it further and the petrol gets to your injectors, having passed through the pump first. - The job expands with the mileage — lines purged, filter sorted, occasionally more. Diesel keeps your high-pressure pump and the fuel injectors oiled as it goes through them. Petrol gives them nothing, and that is why the line is drawn there. Nothing is harmed by petrol that is only resting in a tank. Petrol being pumped is grinding down the components that move the car. ## What to have prepared when you call about petrol in a diesel from Clachnaharry Whether the van circles or finds you comes down to a little planning. - IV3 8 and the remainder of the postcode is the ideal way to start telling us where you are. - Name the road — Clachnaharry Road or wherever you have pulled up — or the car park. - What a car park serves is the easiest way to find it, so mention the landmark — like the one at Co-op Food. - Make and model of the car, and the fact it's a diesel. - Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has a separate Clachnaharry page. - The amount: your receipt's litres, or otherwise how long you held the nozzle in. - The mileage it covered, and how hard, if it has run at all. - Settle who has your car before we arrive: some hire and company agreements want the owner to approve the work, and that is quicker beforehand. Ring 0333 366 0103 once you have got that ready — or, if your car is at home, going nowhere, use . ## While you wait for a fuel drain in Clachnaharry Help, however well meant, is the thing that does the damage while you wait. So stick to these. - Your safety comes before the vehicle. Somewhere exposed? Get away from the traffic and wait away from it. Safe where it sits? Stay with it. - Nobody starts it. Not a passer-by being helpful, not to check it is all right, not to roll the vehicle a couple of yards. - Additives remain in the boot. Injector cleaner and two-stroke oil take none of the petrol out again. - A DIY drain leaves your fuel that has already gone beyond the tank, and siphoning petrol by the road is hazardous too. - Not for the radio, not for your windows: the ignition stays off. ## The fuel drain, step by step, once our van arrives - First, three queries: which fuel went in, the amount, and has it run? Those answers shape the job, so the price follows them. - Draining it's how the blend gets taken from the tank. - Purging your lines follows, because a car that ran has petrol past the tank, inside the lines themselves. - Where your car has a serviceable filter, it is replaced; if not, cleared. - Fresh diesel in, and the fuel system primed. - Starting up. When the system is primed with clean diesel, our technicians start the car and confirm it runs properly. The vehicle has clean diesel running through it before we go. It is very uncommon for a vehicle noticed early to be left with permanent damage, and normal driving starts again right away. ## After the fuel drain: back on the road around Clachnaharry - Started on fresh diesel, it needs nothing special of you. Just 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 is lumpy, or a throttle with a dead spot. - Keep your documents. A hire firm, a fleet manager or an insurer may ask what was done. - Read the label on the petrol pump next time, not the colour of its handle. ## About Clachnaharry and where it is Clachnaharry is a coastal suburban area situated near Inverness, with Clachnaharry being one of the closest suburbs to the city centre.
