Here Is What Happens Whatever you do, don't switch your motor on, even for a moment, to shift it. Pause; leave the vehicle off. The coming few minutes determine it far more than anything else: petrol in a diesel that has not run generally amounts to draining and rinsing, on the spot. What follows is the order from this point, anywhere in Hundred Acres you are. ## Petrol in a diesel, engine off — the first minute Do these before anything else, in this order. - Ignition off, keys out. Switched on, the ignition can prime the system — and priming is what moves petrol out of the tank into the parts it damages. - No diesel on top. More fuel in removes none of that petrol — it only leaves you with extra of the same mixture. - Make your car simple to see before anything else — hazards on — if there is moving traffic anywhere near you. - Off the petrol pump by hand. At a forecourt, get the attendants to help you roll the vehicle away from the petrol pump. Don't fire it up to shift it, however short the distance. - Hold on to the till receipt: the grade and the rough amount are printed 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 M27, under 3 miles from Hundred Acres, that means the next exit. Stage one comes next. ## The fork in every Hundred Acres fuel drain: has it run yet? Everything after this stage depends on one answer. Motor never run at all? - Just your tank has petrol in it for now. - Draining and flushing, on the spot, is normally the whole job. - No position is better, and it's why the first stage matters so much. Engine run, even briefly? - Petrol has been pulled out of that tank, past your filter then into your lines. - A bigger run carries it all the way to your high-pressure pump and your injectors. - The job grows with the distance — lines purged, filter sorted, occasionally more. That line falls there since diesel protects your high-pressure pump and your injectors on its way through them — and petrol does not. Nothing is damaged by petrol that is just resting in a tank. Once it's pumped, petrol starts wearing down whatever moves it. ## Hundred Acres, petrol in a diesel: have these ready before you call A little planning is the difference between a van that finds you and a technician that goes round. - PO17 6 plus the remainder of the postcode makes the best way to start telling us where you are. - Wherever you have pulled up, the road's name is useful — whether that is Hundred Acres Road or somewhere else — and so does the name of a car park. - What a car park serves is the quickest way to find it, and so mention the landmark — such as the one at Sainsbury's. - Tell us what the vehicle is — make, model — and check it is diesel. - Which went in matters: AdBlue is a separate job from petrol, and Hundred Acres has a page just for that. So tell us. - The quantity: the receipt's litres, or otherwise how long you had the nozzle in. - Has it run? If so, tell us how far it got, and how it was driven. - Sort who has your car ahead of when we turn up: some hire or company contracts want the owner to authorise the work, and that is quicker first. Then phone 0333 366 0103. If it can wait — the vehicle is at home and going nowhere — does the trick as well. ## Hundred Acres fuel drain on its way? Whilst you wait Help, however well meant, is the thing that does the harm whilst you wait. So hold to these. - Where the car has stopped decides where you wait. Somewhere exposed: away from it, away from the traffic. Safe: with it. Either way, safety before the car. - Not to roll it a couple of yards, not to check it is all right, not as a passer-by's kindness: nobody starts it. - No additives. Two-stroke oil, injector cleaner, something from the boot — none of it takes the petrol back out. - A home-made drain misses the fuel that has already gone beyond your tank, and siphoning petrol by the road is hazardous too. - Ignition remains off. Even for the radio or your windows. ## Step by step: your fuel drain when our van arrives - The quote comes after three queries, not before them — what got in, how much, and if it has run — since the answers shape this job. - Out of the tank comes the contaminated blend: that tank is cleared. - Flushing the lines follows, because a motor that ran has petrol past that tank, in your lines themselves. - Where your car has a serviceable filter, it is replaced; if not, cleared. - Fresh diesel in, and the system primed. - The first start on clean diesel. Once priming is done, the engine is started and we confirm that it runs properly. Until it runs on fresh diesel, our technicians stay with it. When it has been noticed early, permanent damage is very uncommon, and the vehicle goes back to normal driving straight away. ## Hundred Acres, after your fuel drain: back on the road - Drive normally. There's nothing special to do after it's been started on clean fuel. - Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or your throttle hesitating: pull over and ring us back. - Keep the documents. A hire company, a fleet manager or an insurer may ask what was done. - Next time, read the pump. The label, not the colour of the handle. ## About Hundred Acres itself Hundred Acres is a small village in Hampshire, situated inland at an elevation of 52 metres, and is located near the cities of Portsmouth and Southampton.
