Motor off. Leave the vehicle that way — no second on, no shifting it at all. Has not been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever your car has stopped — and nothing decides that as much as the next few minutes do. Here's the order of things from here, wherever you're in Pant y Pwdyn. ## Motor off: minute one with petrol in a diesel Work through the following in sequence, first. - Priming your fuel system pulls petrol from the tank towards the components it harms, and switching your ignition on can be all it takes to do that. So the keys get taken out, and your ignition stays off completely. - A fuller tank of the same mixture is all topping up leaves you, since it removes nothing. So no extra diesel. - Hazards on. If you are at all near moving traffic, make the car easy to see before you do anything else. - By hand, never on the motor: that is how it comes off the pump. Ask the forecourt attendants to help you push, whatever the miles. - Which fuel, and about how much? Your receipt replies that, and that's where our first question starts. Don't bin it. Still driving when you noticed? Come off the M4 at the next exit if that's where you are, under 15 miles from Pant y Pwdyn, and stop somewhere sensible and not pressing on to the services. Then start at stage one. ## Each Pant y Pwdyn fuel drain starts here: has your engine run? What happens after this turns on one answer, and only one. Motor not run at all? - No place but the tank: that is where the petrol yet is. - Draining and flushing, on the spot, is usually the whole job. - Step one matters for exactly this reason: it's the best spot to be in. If it has been started, even for a second: - Some petrol has left the tank already, gone through the fuel filter, and got into the fuel lines. - Run it further and that petrol reaches the fuel injectors, having gone through the fuel pump first. - The job expands with the distance — lines purged, filter sorted, sometimes more. Petrol doesn't lubricate. Diesel does, oiling the pump and injectors as it passes through, which is why the line falls where it does. A tank of petrol, left alone, damages nothing. Once it's pumped, petrol begins wearing whatever moves it. ## Calling about petrol in a diesel from Pant y Pwdyn: what to have prepared Whether the van goes round or finds you depends on a little preparation. - The best start is a postcode — one beginning NP13 1 — for where you are. - The road or the car park. A road name is a help — Pen Rhiw Garreg Road, or wherever you have stopped. - Name a car park by what it serves — the one outside Tesco, for instance — and it is far quicker to find. - That it is a diesel, along with the make and model of your car. - What went in. Petrol, or AdBlue. AdBlue is a different job with its own page for Pant y Pwdyn, and so say which. - How long the nozzle was in, or the litres on your receipt — either tells us how much. - The mileage it covered, and how heavily, if it has run at all. - The owner may have to authorise the work under some hire or company contracts — which is why it is faster to settle whose motor it is before our engineers arrive. Phone 0333 366 0103 once you've got that together — or, if the car is at home, going nowhere, use . ## While you wait for a fuel drain around Pant y Pwdyn The wait is where well-intended help does the harm. Hold to these. - Where the car has stopped decides where you wait. Exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety before the car. - A kind passer-by does not start it. Nor does anybody checking it still works, or rolling it a couple of yards. - Anything from the boot, oil meant for two-strokes or injector cleaner: no additive lifts that petrol. - No home-made draining. Siphoning petrol into a can at the kerbside is risky, and it leaves the fuel that has by now gone beyond the tank. - Not for your radio, not for the windows: the ignition stays off. ## When the van arrives: the fuel drain, step by step - Fuel, quantity, whether it has run: the replies decide this job, and that is why we give a quote after them rather than before. - Out of your tank comes the polluted mix: the tank is emptied. - Purging the lines comes next, because a car that ran has petrol past that tank, inside your lines themselves. - Then the fuel filter: swapped where there is a usable one, cleared where there's not. - Priming follows once fresh diesel is in. - The start. With new diesel in and the system primed, it's fired up and tested to confirm it runs correctly. We stay until it's running on fresh diesel. Permanent damage is very uncommon when it has been spotted early, so the car can go right back to normal driving. ## After the fuel drain: back on the road around Pant y Pwdyn - Started on fresh diesel, it asks nothing special of you. Simply drive normally. - Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or your throttle hesitating: pull over then call us back. - The work may come up later with a hire company, an insurer or a fleet manager. Keep your paperwork. - Read the label on the pump next time, not the colour of its handle. ## About Pant y Pwdyn and where it is Pant y Pwdyn is a suburban area situated on the riverside in Blaenau Gwent, with a mix of terraced housing and a population of around 4350 residents.
