Here Is What Happens Whatever you do, don't switch your motor on, even briefly, to shift the vehicle. Pause; leave the vehicle off. Petrol in a diesel that hasn't been run is usually a simple drain and a flush, done right where your car sits, and what you do in the next few minutes determines that far more than anything else. What follows is the order from this point, anywhere around Withywood you happen to be. ## Petrol in a diesel, engine off — the first minute In this sequence, and before anything else: - Priming the fuel system pulls petrol from the tank towards the parts it damages, and turning your ignition on can be all it takes to do that. So your keys come out, and your ignition stays off completely. - Topping up with diesel sounds like it thins the problem. It does not: nothing gets out, and that tank just holds more of the same. - Hazards on. If you are anywhere close to moving traffic, make the vehicle simple to see before you do anything else. - By hand, not under the motor: that is how it comes off the pump. Get the forecourt staff to help you push, whatever the mileage. - The first thing you will be asked is which fuel you put in and roughly how much — and the receipt says both. Keep it. Noticed on the move? Get off at the next junction if you are on the M32, under 5 miles from Withywood, and pull over somewhere sensible — not at the services further on. Stage one comes after that. ## The fork in every Withywood fuel drain: has it run yet? What happens after this rests on one answer, and just one. Not run, not even briefly: - That petrol is still in your tank and nowhere else. - The work is a drain and a flush, usually done where the vehicle stands. - Step one counts for exactly this reason: it's the best spot to be in. Engine run, however for a moment? - The fuel lines and your filter now carry petrol drawn out of your tank. - On a bigger run it has reached your high-pressure pump and the fuel injectors. - Flushing your lines, the filter seen to, and sometimes more: this job grows as the distance does. The line falls there because diesel protects the high-pressure fuel pump and the fuel injectors on its way through them — and petrol does not. In the tank, sitting still, petrol harms nothing. Once it is pumped, petrol begins wearing whatever moves it. ## What to have ready when you call about petrol in a diesel from Withywood Whether the technician goes round or finds you comes down to a little planning. - Your location: a postcode beginning BS13 8 works best. - The street or the car park. A road name is a help — Three Wells Road, or wherever you have stopped. - Or the landmark. A car park is quicker to find by what it serves, like the one outside Kwik Save. - The car. Make, model, plus that it is a diesel. - Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has a separate Withywood page. - How much. Litres from the receipt, or how long the nozzle was in the filler. - If it's run, how far and how hard — and if it has run at all. - Settle who owns the car ahead of when our technicians get there: some hire or company contracts want the owner to authorise the work, and doing it quicker beforehand. Next, 0333 366 0103. Not pressing, the car left at home with nowhere to be? Then works as well. ## Waiting for a fuel drain in Withywood: what to do The wait is where well-meant help does the damage. Hold to these. - Stay with your car if it is safe where it is — but if it has stopped somewhere dangerous, you come first: away from the traffic, waiting apart from it. - Nobody starts it. Not a passer-by being kind, not to check it is all right, not to roll it a couple of yards. - None of it gets the petrol back out — not two-stroke oil, not injector cleaner, not anything from your boot. So no additives. - A home-made drain misses your fuel already gone beyond your tank, and siphoning petrol by the road is dangerous too. - Not for the radio, not for the windows: your ignition remains off. ## Van arrived? Your fuel drain, one step at a time - First, three queries: which fuel went in, the quantity, and has it run? Those answers shape the job, and so our price follows them. - The tank is cleared. The polluted mix comes from that tank. - If it ran, the fuel lines are carrying petrol that has moved beyond your tank — so they are flushed. - The filter is sorted. Cleared, or swapped where your car has a serviceable one. - Fresh diesel in, and the system primed. - The start. With clean diesel in and your system primed, it is started and tested to make sure it runs smoothly. Your car has new diesel running through it before our technicians go. If it has been spotted early, lasting damage is very rare, and the vehicle returns to normal driving straight away. ## After your fuel drain: back on the road in Withywood - Nothing unusual is needed after a start with fresh diesel — normal driving will do. - Watch the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle means pull over then ring us back. - An insurer, a fleet manager or a hire firm may ask what was carried out, so hold on to your paperwork. - Next time, go by the pump's label rather than the colour of its handle. ## About Withywood itself Withywood is a suburban area in Bristol, situated near the River Avon and characterised by its semi-detached housing stock.
