Motor off. Keep the car like that — no moment on, no shifting it at all. The next few minutes determine it far more than anything else: petrol in a diesel still unrun generally comes down to emptying and flushing, right there. Here is the sequence of things from now, anywhere you're around Old Netley. ## Petrol in a diesel? What to do in minute one Work through these before anything else, in this sequence. - The ignition off, keys out. Turned on, your ignition can prime your system — and priming is what draws petrol out of your tank into the parts it harms. - A bigger tank of the same mix is all topping up gives you, since it removes nothing. So no more diesel. - Get your car easy to see first — hazards on — if there's traffic going past anywhere close to you. - Off the petrol pump by hand. On a forecourt, get the attendants to help you push the vehicle away from the pump. Do not start the vehicle to move it, however short the distance. - The first thing we will ask is which fuel you put in and roughly how much — and the receipt says both. Hold on to it. Noticed on the move? Get off at the next junction if you're on the M27, under a mile from Old Netley, and pull over somewhere sensible — not at the services further on. Step one starts after that. ## Every Old Netley fuel drain starts here: has the motor run? What comes after this rests on one answer, and just one. If the motor has not run at all: - That petrol is still inside that tank and nowhere else. - Where your car stands is usually where this work happens: a drain, then a flush. - No place is better, and it's why the first stage matters so much. If your motor has been run, even for a moment: - Petrol has been pulled out of that tank, past the fuel filter then into the fuel lines. - A bigger run carries it all the way to the high-pressure fuel pump and the injectors. - Lines flushed, the filter seen to, and sometimes more: the job grows as the mileage does. Petrol doesn't lubricate. Diesel does, protecting your high-pressure pump and injectors as it flows through, which is why the line falls where it does. Petrol resting in a tank harms nothing. Petrol being pumped is wearing the components that shift the vehicle. ## Calling about petrol in a diesel from Old Netley: what to have prepared Prepare a little, and the van finds you rather than circling. - Your location: a postcode beginning SO31 8 works best. - Name the street — Elmslie Gardens or wherever you have pulled up — or the car park. - Or the landmark. A car park is easier to find by what it serves, like the one outside Tesco Extra. - Say what the car is — make, model — and confirm it is diesel. - Say which got in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Old Netley. - About how much — in litres from your receipt, or by how long the nozzle stayed in. - Has it run? If so, tell us how far it got, and how it was driven. - Hire or company car? Some contracts want the owner's authorisation for the work, and sorting it before we get there is faster than afterwards. Ring 0333 366 0103 next. Writing to is fine too if it can wait, with the car parked at home, going nowhere. ## Whilst you wait for a fuel drain around Old Netley During the wait, the damage comes from well-intended help — which is why these matter. - Wait with your car if it is safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it. - Not to roll it a few yards, not to check it is all right, not for a passer-by's favour: nobody starts it. - Additives stay in the boot. Injector cleaner and two-stroke oil draw none of the petrol out again. - No DIY emptying. Siphoning petrol into a can by the roadside is dangerous, and it leaves the fuel that has already gone beyond that tank. - Ignition stays off. Even for your radio or the windows. ## When our van arrives: your fuel drain, step by step - Our quote comes after three questions, not before them — what got in, how much, and if it's run — since those replies decide this job. - The tank is cleared. The tainted mix comes out of the tank. - The lines are purged. If it ran, the petrol has shifted beyond the tank, and the lines are holding it. - Your filter is seen to. Cleared, or changed where the car has a usable one. - Clean diesel goes in, and your system is primed. - The start-up. With fresh diesel in and the system primed, it is fired up and tested to make sure it runs correctly. We remain until it's running on fresh diesel. If it has been caught quickly, lasting damage is very rare, and the vehicle goes back to normal use right away. ## After your fuel drain: back on the road around Old Netley - Nothing unusual is needed after a start with clean diesel — normal driving is all. - The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your cue to stop and ring us once more. - The work may matter later with a hire firm, an insurer or a fleet manager. Hold on to your paperwork. - Next time, go by the pump's label instead of the colour of its handle. ## About Old Netley and where it is Old Netley is a coastal village in Hampshire, situated near the city of Southampton and overlooking the Southampton Water.
