Pause there. The next few minutes decide it far more than anything else: petrol in a diesel that has not run usually amounts to emptying then flushing, right there. From here on, step by step, wherever you are around Holt: ## Petrol in a diesel? What to do in minute one Do these first, in this order. - The ignition off, keys out. Switched on, your ignition can prime your system — and priming is what draws petrol out of the tank into the components it damages. - A bigger tank of the same mixture is all topping up leaves you, since it takes out nothing. So no extra diesel. - Get your car simple to see before anything else — hazards on — if there is moving traffic anywhere close to you. - By hand, never under your engine: that's how it leaves the petrol pump. Ask the forecourt staff to help you push, however short the miles. - The first question you will be asked is which fuel went in and about how much — and the till receipt says both. Keep it. Realised on the move? Get off at the next junction if you are on the M53, under 10 miles from Holt, and pull over somewhere safe — not at the services further on. Stage one comes after that. ## Has it run yet? The fork in each Holt fuel drain From this stage on, everything hinges on a single answer. Engine never run at all? - Nowhere but the tank: that is where the petrol yet is. - Usually it is drained and purged right where the vehicle is. - This is the best case — which is the whole point of stage one. If the engine has run, even briefly: - Some petrol has left the tank already, passed through the fuel filter, and reached your lines. - Run it farther and that petrol gets to the injectors, having passed through the pump first. - The job grows with the mileage — lines rinsed, filter dealt with, occasionally more. The line falls there since diesel lubricates your high-pressure pump and the fuel injectors on its way through them — and petrol doesn't. In that tank, sitting still, petrol does no harm. As soon as it's pumped, petrol begins grinding whatever moves it. ## Before you call about petrol in a diesel in Holt: what our technicians need A technician that circles versus a technician that finds you: a little preparation is the difference. - Where you have stopped. A postcode beginning LL13 9 is the ideal place to start. - Wherever you have parked, the road's name is useful — whether that is Frog Lane or somewhere else — and so does the name of a car park. - Describe a car park by what it serves — the one at Asda, for instance — and it is much easier to find. - That it's a diesel, along with the make and model of your vehicle. - Say which was put in — petrol or AdBlue — since AdBlue is a separate job, with a page of its own for Holt. - About how much — in litres from the receipt, or by how long the nozzle was in. - If it has run, how far plus how hard — as well as if it's run at all. - Sort who has the vehicle ahead of when we arrive: some hire and company contracts want the owner to authorise this work, and doing it quicker beforehand. Next, 0333 366 0103. Not urgent, the vehicle parked at home with nowhere to be? Then will do too. ## Holt fuel drain on its way? Whilst you wait In the wait, the damage comes from well-meant help — so these matter. - Where your car has stopped decides where you wait. Somewhere exposed: away from it, away from the traffic. Sensible: with it. Either way, safety ahead of the vehicle. - A helpful passer-by doesn't start it. Nor does anyone checking it still does the trick, or rolling it a few yards. - Something from the boot, oil meant for two-strokes or injector cleaner: no additive lifts that petrol. - No DIY clearing. Siphoning petrol into a can at the kerbside is risky, and it leaves your fuel that has already gone beyond that tank. - Ignition remains off. Even for the radio or your windows. ## Van arrived? Your fuel drain, one stage at a time - The quote comes after three queries, not before them — what got in, how much, and if it has run — because the answers decide the job. - Your tank is emptied. The contaminated mixture comes out of the tank. - Petrol that has shifted beyond the tank sits in your lines if it ran, and the lines are flushed to shift it. - Where the vehicle has a workable filter, it is changed; otherwise, cleared. - Fresh diesel in, and the fuel system primed. - Starting it. Once the fuel system is bled with new diesel, our technicians start it and make sure it runs smoothly. Your car has fresh diesel running through it before our technicians go. It is very rare for a car noticed quickly to be left with permanent damage, and normal use resumes right away. ## Back on the road in Holt after your fuel drain - Drive normally. There's nothing unusual to do after it has been started on clean fuel. - Give the first miles your attention. Smoke showing, a warning light coming on, your idle going lumpy or the throttle stumbling: pull over then call us back. - An insurer, a fleet manager or a hire firm may ask what was carried out, and so hold on to your paperwork. - Read the label on the pump next time, not the colour of its handle. ## About Holt Holt is a village situated on the banks of the River Dee in northeast Wales, approximately 5 miles from Wrexham.
