Stop; leave the car off. The coming few minutes determine it far more than anything else: petrol in a diesel still unrun normally comes down to draining and purging, on the spot. Below is the sequence from this point, anywhere around Lydford-on-Fosse you are. ## Petrol in a diesel? What to do in minute one Work through the following first, in this order. - Keys out of your ignition. Turning your ignition on can be enough to prime your fuel system, and priming draws petrol out of your tank toward the parts it damages. Keep it off completely. - Topping up with diesel seems like it thins the issue. It does not: nothing comes out, and the tank just holds more of the same. - Hazard lights on. If you are anywhere close to moving traffic, make the vehicle simple to see before you do anything else. - By hand, never under the motor: that is how it comes off the petrol pump. Ask the forecourt staff to help you push, however short the distance. - Keep the till receipt: the grade and the rough amount are written on it, and they are what our engineers ask about first. If you were still driving when you realised, stop somewhere sensible rather than pushing on for the services — on the M5, under 25 miles from Lydford-on-Fosse, that means the next exit. Step one comes next. ## Lydford-on-Fosse fuel drain: has the engine run yet, or not? One answer is what everything after this point depends on. Not run, not even once: - All the petrol sits inside the tank, and just there. - Usually it's drained and cleaned just where the car stands. - This is the best case — which is the entire point of stage one. If your engine has run, even for a moment: - The lines and the fuel filter already carry petrol drawn from the tank. - A bigger run takes it all the way to your high-pressure pump and your injectors. - Distance is what turns it into a bigger job: flushed lines, a filter seen to, and at times further work. That line falls there since diesel lubricates the high-pressure pump and the fuel injectors on its way through them — and petrol doesn't. In the tank, left alone, petrol does no harm. The parts that move it are grinding the moment petrol is being pumped. ## Calling about petrol in a diesel from Lydford-on-Fosse: what to have ready Whether the van circles or finds you comes down to a little planning. - Where you have stopped. A postcode starting TA11 7 is the ideal start. - Wherever you have pulled up, the road's name helps — whether that's Foss Way or somewhere else — and so does the name of a car park. - Or the nearest landmark. A car park is quicker to find by what it serves, such as the one at Co-op Food. - The make and model of the vehicle, and the fact it's a diesel. - Which went in counts: AdBlue is a separate job from petrol, plus Lydford-on-Fosse has a page for it. So tell us. - How much. Litres from your receipt, or how long the nozzle was in the filler. - The miles it did, and how hard, if it ran at all. - Hire or company car? Some contracts need the owner's authorisation for this work, and getting it before we arrive is quicker than after. Then call 0333 366 0103. If it can wait — the vehicle is at home with going nowhere — does the trick as well. ## Lydford-on-Fosse fuel drain on its way? While you wait The wait is where well-intended help does the damage. Stick to these. - Safety before the car. If it has stopped somewhere exposed, get yourself clear of the traffic then wait away from it. If it is safe where it sits, stay with it. - A helpful passer-by doesn't fire it up. Nor does anyone wanting to check it still works, or rolling it a few yards. - Additives remain in the boot. Injector cleaner and two-stroke oil take none of the petrol out a second time. - A home-made drain leaves the fuel already gone beyond the tank, and siphoning petrol by the road is hazardous besides. - Ignition stays off. Even for your radio or the windows. ## When our van arrives: the fuel drain, step by step - Fuel, quantity, whether it has run: the replies set the job, and that is why we give a price after them instead of before. - Out of your tank comes the tainted mixture: your tank is emptied. - The fuel lines are flushed. If it ran, that petrol has moved beyond that tank, and your lines are holding it. - Your filter is seen to. Cleared, or swapped where the vehicle has a serviceable one. - Fresh diesel goes in, and the fuel system is primed. - Our engineers fire it up only after clean diesel has gone in and primed your system, then check that it is running properly. We wait until it's running on fresh diesel. Your car returns to normal use straight away, and lasting damage is very uncommon when it has been caught soon. ## Lydford-on-Fosse, after the fuel drain: back on the road - Nothing special is needed after a start with clean diesel — usual driving will do. - Give the first miles your attention. Smoke showing, a warning light coming on, your idle going lumpy or the throttle stumbling: pull over then ring us back. - An insurer, a fleet manager or a hire company may ask what was carried out, and so hold on to the paperwork. - Read the label on the pump next time, not the colour of its handle. ## About Lydford-on-Fosse and where it is Lydford-on-Fosse is a small village in Somerset, situated inland at an elevation of 39 metres, approximately 9 miles from the city of Wells.
