Stop there. Petrol in a diesel that hasn't been run is generally a drain plus a flush, done where the car sits, and what happens in the coming few minutes decides that more than anything else. Below is the order from this point, anywhere around Whitehill you are. ## Engine off: minute one with petrol in a diesel In this sequence, all before everything else: - The keys out of your ignition. Turning your ignition on can be all it takes to prime your fuel system, while priming draws petrol out of your tank towards the components it harms. Keep the car off altogether. - Topping up with diesel seems like it dilutes the problem. It does not: nothing comes out, and that tank just carries more of the same. - Being seen comes before the rest beside moving traffic: switch your hazards on, and only then think about anything else. - The attendants will usually help you push it away from the petrol pump. Ask, and roll it by hand — never under the engine, even for a couple of yards. - Hold on to the till receipt: the fuel and roughly how much are written on it, and they're what we ask about first. Still driving when you noticed? Come off the M23 at the next exit if that's where you are, under 15 miles from Whitehill, and pull over somewhere sensible and not pushing on to the services. Then begin at step one. ## Whitehill fuel drain: has the motor run yet, or not? From this stage on, everything hinges on a single answer. If the motor has not run at all: - Only that tank has petrol in it for now. - Where the car sits is usually where the work is done: a drain, then a flush. - This is the best place to be in, and the reason step one matters. If it has been started, even for a second: - The lines and the fuel filter now carry petrol drawn out of that tank. - A longer run carries it right through to your high-pressure pump and the injectors. - Miles is what makes it a bigger job: flushed lines, a filter seen to, and at times further work. That line falls there because diesel lubricates your high-pressure pump and your injectors on its way through them — and petrol does not. Petrol sitting in a tank harms nothing. Petrol being pumped is wearing the components that shift it. ## What to have prepared when you call about petrol in a diesel from Whitehill Prepare a little, and the technician finds you instead of circling. - Your location: a postcode starting TN6 1 serves best. - A road name is a help: Alice Bright Lane, say, or whichever street you have stopped in. A car park does the trick too. - Name a car park by what it serves — the one outside Waitrose, for instance — and it's much easier to find. - The car. Make, model, and that it's a diesel. - What was put in. Petrol, or AdBlue. AdBlue is a different job with its own page for Whitehill, and so say which. - Roughly how much — in litres from the receipt, or by how long the nozzle was in. - If it's run, how far plus how hard — and whether it's run at all. - Settle who owns the vehicle ahead of when our technicians turn up: some hire and company contracts want the owner to approve this work, and doing it quicker beforehand. Then phone 0333 366 0103. If it can wait — your car is at home with going nowhere — does the trick too. ## Waiting for a fuel drain around Whitehill: what to do The wait is where well-intended help does the harm. Hold to these. - Where the car has stopped settles where you wait. Somewhere exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety before the car. - No one starts it. Not a passer-by being kind, not to check it is all right, not to roll it a few yards. - None of it gets the 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 roadside is dangerous — and it still leaves whatever fuel has already gone beyond the tank. Do not try a home-made drain. - Not for the radio, not for the windows: your ignition stays off. ## Van arrived? Your fuel drain, one step at a time - Fuel, quantity, whether it has run: those replies decide this job, and that is why we give a price after them instead of before. - Draining it's how the mixture gets taken from the tank. - Petrol that has moved beyond the tank sits in the lines if it ran, and the fuel lines are rinsed to shift it. - Then the filter: replaced where there's a workable one, cleared where there's not. - The system is primed with fresh diesel. - First start on clean diesel. When bleeding is complete, the motor is fired up and we confirm that it runs correctly. Only once it's running on fresh diesel do our technicians go. Long-term damage is very unusual if it has been noticed quickly, so the car can go straight back to normal driving. ## Back on the road around Whitehill after the fuel drain - Nothing special is needed after a start with clean diesel — ordinary driving will do. - The first miles are the test. A dash warning, exhaust smoke, a rough idle or a flat throttle is your cue to stop then call us a second time. - The work may come up later with a hire company, an insurer or a fleet manager. Keep the paperwork. - The handle's colour isn't the thing to go by next time — the label on the pump is. ## About Whitehill, briefly Whitehill is a suburban area in East Sussex, situated inland at an elevation of 182 metres, and is located near the towns of Alderbrook and Stone Cross.
