The next few minutes determine it far more than anything else: petrol in a diesel that has not run normally amounts to clearing then flushing, right there. Below is the sequence from here, anywhere in Neath Abbey you are. ## Minute one: petrol in a diesel, engine off In this sequence, all before everything else: - Keys out of the ignition. Switching the ignition on can be all it takes to prime the fuel system, while priming draws petrol out of your tank towards the parts it harms. Leave the vehicle off completely. - A bigger tank of the same mix is all adding diesel leaves you, since it takes out nothing. So no more diesel. - Close to passing traffic? Then the hazards go on before everything else, and so the vehicle is easy to spot. - Off the pump by hand. At a forecourt, ask the staff to help you roll it clear of the petrol pump. Don't start the car to move it, however short the way. - Hold on to your receipt. It shows which fuel got in plus about how much, which is the first thing we'll ask. Realised on the move? Get off at the next junction if you're on the M4, under 3 miles from Neath Abbey, and stop somewhere safe — not at the services farther on. Step one starts after that. ## Every Neath Abbey fuel drain starts here: has your motor run? What happens next turns on one answer, and just one. If your motor has not run at all: - That petrol is still inside your tank and nowhere else. - Draining and flushing, on the spot, is normally the whole job. - This is the best case — which is the entire point of stage one. Motor run, even for a moment? - Out of that tank, past the fuel filter, into your lines: that is how far that petrol has got. - Run it further and the petrol gets to the fuel injectors, having passed through the fuel pump first. - Flushing your lines, the fuel filter seen to, and sometimes more: this job expands as the distance does. The reason the line falls there: diesel protects your high-pressure pump as well as your injectors as it passes through them, and petrol does not. Nothing is damaged by petrol that's only sitting in a tank. Pump the petrol, though, and it grinds down the very parts doing the moving. ## Neath Abbey, petrol in a diesel: have these prepared before you call Whether the technician goes round or finds you depends on a little preparation. - Where you are. A postcode starting SA10 7 is the best place to start. - Give the road — Penyard Road or wherever you have pulled up — or the car park. - Car parks are found more easily by what they serve: tell us the one outside Tesco, and it is simple. - The vehicle. Make, model, plus that it's a diesel. - Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has a separate Neath Abbey page. - The quantity: the receipt's litres, or otherwise how long you had the nozzle in. - If it has run, how far plus how hard — as well as whether it's run at all. - Settle who owns the car ahead of when our technicians turn up: some hire and company agreements want the owner to authorise the work, and that is faster first. Call 0333 366 0103 once you have got that ready — or, if the car is at home, going nowhere, use . ## Waiting for a fuel drain around Neath Abbey: what to do The wait is where kindly meant help does the harm. Hold to these. - Stay with the car if it is safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it. - A kind passer-by doesn't start it. Nor does anyone checking it still works, or rolling it a few yards. - None of it gets the petrol back out — not two-stroke oil, not injector cleaner, not anything from your boot. So no additives. - Emptying it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and the fuel beyond the tank remains put all the same. - Ignition stays off. Even for the radio or your windows. ## When our van arrives: your fuel drain, step by step - First, three queries: which fuel was put in, the quantity, and has it run? Those answers shape the job, so our quote follows them. - Out of the tank comes the polluted blend: the tank is cleared. - If it ran, the lines are carrying petrol that has moved beyond your tank — so they are rinsed. - Where your car has a serviceable filter, it's swapped; otherwise, cleared. - Clean diesel in, and your system primed. - The first start on clean diesel. Once bleeding is finished, your engine is started and our technicians check that it runs correctly. Till it runs on new diesel, our technicians remain with it. When it has been spotted quickly, lasting damage is very unusual, and the car goes back to normal driving right away. ## Neath Abbey, after your fuel drain: back on the road - Nothing special is needed after a start with clean diesel — usual driving will do. - Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle means pull over then call us back. - Keep your paperwork. A hire company, a fleet manager or an insurer may ask what was carried out. - Next time, go by the petrol pump's label rather than the colour of its handle. ## About Neath Abbey Neath Abbey is a suburban area situated on the riverside in Neath Port Talbot, with a mix of detached housing and local amenities.
