Motor off. Leave the car like that — no moment on, no moving it at all. Emptied and flushed, just where it is: that is normally all an unrun diesel with petrol in it takes. Whether it remains that straightforward rests on the minutes ahead more than on everything else. Below is the sequence from this point, anywhere around Holbear you happen to be. ## Minute one: petrol in a diesel, motor off In this sequence, and before everything else: - Ignition off, keys out. Turned on, your ignition can prime the system — and priming is what draws petrol out of the tank towards the parts it harms. - Topping up with diesel seems like it thins the problem. It doesn't: nothing comes out, and your tank simply carries more of the same. - Get your car simple to see first — hazard lights on — if there is traffic going past anywhere close to you. - However short the distance, starting it to shift it is the mistake. On a forecourt, push the vehicle clear of the pump by hand instead, then ask the staff to lend a hand. - Hold on to the till receipt: the grade and the rough amount are written on it, and they are what we ask for first. If you were still driving when you noticed, pull over somewhere sensible rather than pushing on for the services — on the M5, under 15 miles from Holbear, that means the next junction. Stage one comes next. ## Holbear fuel drain: has the motor run yet, or not? What comes after this rests on one answer, and just one. Not run, not even once: - Just your tank has petrol in it so far. - Usually it is emptied and flushed right where the car is. - No spot is better, and it's why the first step matters so much. Engine run, even briefly? - Out of the tank, through the fuel filter, into the lines: that's how far the petrol has got. - Your high-pressure pump as well as the fuel injectors see it too on a longer run. - The further it went, the larger this job — the fuel lines, the fuel filter, and now and then more besides. That line falls there because diesel protects your high-pressure pump and the injectors on its way through them — and petrol doesn't. Petrol sitting in a tank harms nothing. As soon as it is pumped, petrol starts grinding whatever moves it. ## What to have prepared when you call about petrol in a diesel from Holbear Get ready a little, and the van finds you rather than circling. - The best start is a postcode — one starting TA20 2 — for where you have stopped. - Wherever you have parked, the road's name is useful — whether that is Holbear or somewhere else — and so does the name of a car park. - What a car park serves is the quickest way to find it, so mention the landmark — like the one outside Lidl. - That it's a diesel, along with the make and model of the vehicle. - Tell us which went in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Holbear. - How long the nozzle was in, or the litres from the receipt — either gives us how much. - The mileage it covered, and how heavily, if it has run at all. - The owner may have to authorise the work under some hire or company contracts — so it's quicker to settle whose vehicle it is before our engineers get there. Ring 0333 366 0103 once you've got that ready — or, if the car is at home, going nowhere, use . ## While you wait for a fuel drain around Holbear The wait is where well-intended help does the harm. Hold to these. - Where your car has stopped decides where you wait. Exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety before the vehicle. - No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll the car a couple of yards. - None of that takes that petrol back out — not two-stroke oil, not injector cleaner, not something from the boot. So no additives. - Siphoning petrol into a can by the kerbside is hazardous — and it also leaves whatever fuel has already gone beyond your tank. Do not try a home-made drain. - The ignition remains off. Even for the radio or your windows. ## Step by step: the fuel drain when the van gets there - Three questions. What went in, how much, and if it's run. Those answers decide this job, which is why our quote comes after them and not before. - Draining it is how the mixture gets taken from your tank. - Flushing the fuel lines follows, since a vehicle that ran has petrol past the tank, in the lines themselves. - Where the vehicle has a usable filter, it is replaced; otherwise, cleared. - Clean diesel goes in, and the system is primed. - Starting the car. Once the system is bled with clean diesel, our technicians fire it up and confirm it runs properly. Our engineers stay until it's running on new diesel. Your car goes back to normal use straight away, and lasting damage is very uncommon if it has been noticed soon. ## Holbear, after the fuel drain: back on the road - Drive normally. There's nothing unusual to do once it has been started on fresh fuel. - Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or the throttle hesitating: pull over and ring us back. - The work may come up later with a hire company, an insurer or a fleet manager. Hold on to the documents. - Next time, read the pump. The label, not the colour of the handle. ## About Holbear Holbear is a suburban area in Somerset, situated inland at an elevation of 112 metres, with semi-detached housing being the predominant type of accommodation.
