Pause there. Hasn't been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever your car has stopped — and no other factor decides that more than the next few minutes do. Here's the order of things from here, wherever you're around Five Locks. ## Petrol in a diesel? What to do in minute one First, these — following this sequence. - Take the keys out. Even the ignition on its own can prime your fuel system, pulling petrol out of the tank to precisely the parts it harms, and so keep the vehicle alone entirely. - A bigger tank of the same mixture is all topping up leaves you, since it removes nothing. So no extra diesel. - Visibility comes before the rest near moving traffic: put your hazards on, and only then deal with everything else. - Off the petrol pump by hand. At a forecourt, get the attendants to help you roll the car away from the petrol pump. Do not crank it to shift it, however short the distance. - Hold on to the receipt. It shows which fuel got in plus about how much, which is the first thing we'll ask. Still driving when you noticed? Come off the M4 at the next exit if that is where you are, under 5 miles from Five Locks, and stop somewhere sensible instead of pushing on to the services. Then start at step one. ## Five Locks fuel drain: has the motor run yet, or not? From this stage on, everything comes down to a single answer. Not run, not even once: - Nowhere but the tank: that's where the petrol still is. - Draining and flushing, on the spot, is normally the whole job. - No position is better, and it is why the first step counts so much. Run at all, even for a second: - Petrol has been drawn from your tank, past the filter then into your lines. - Run it farther and the petrol gets to the fuel injectors, having passed through your pump first. - Distance is what turns it into a bigger job: flushed lines, a filter seen to, and at times more than that. Petrol doesn't lubricate. Diesel does, oiling your high-pressure pump and injectors as it flows through, which is why the line falls where it does. A tank of petrol, left alone, hurts nothing. The parts that move it are wearing the moment petrol is being pumped. ## Five Locks, petrol in a diesel: have these ready before you call A van that circles against a van that finds you: a little preparation is what separates them. - Where you have stopped. A postcode starting NP44 1 is the ideal start. - Wherever you have parked, the road's name is useful — whether that is Ty Pwca Place or somewhere else — and so does the name of a car park. - What a car park serves is the quickest way to find it, so mention the landmark — like the one outside Aldi. - Tell us what your car is — make, model — and check it's diesel. - Which got in matters: AdBlue is a separate job from petrol, plus Five Locks has a page just for that. So say. - About how much — in litres from your receipt, or by how long the nozzle stayed in. - The mileage it did, and how hard, if it has run at all. - Whose motor it is. Some hire and company contracts want the owner to authorise the work, and that is easier settled before we get there than after. Phone 0333 366 0103 then. Writing to is fine too if it can wait, with the vehicle left at home, going nowhere. ## Waiting for a fuel drain around Five Locks: what to do During the wait, the harm comes from well-intended help — which is why these count. - Stay with the car if it's safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it. - No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll it a few yards. - No additives. Two-stroke oil, injector cleaner, something from the boot — none of it takes the petrol back out. - No home-made clearing. Siphoning petrol into a can at the roadside is risky, and it leaves your fuel that has by now gone beyond that tank. - Leave your ignition off — your windows and the radio included. ## Step by step: your fuel drain when the van arrives - First, three queries: which fuel got in, the volume, and has it run? Those replies shape this job, so the price follows them. - Emptying it is how the mixture gets taken from the tank. - If it ran, the lines are carrying petrol that has shifted beyond the tank — so they're flushed. - Then the filter: replaced where there is a usable one, cleared where there's not. - Priming comes after fresh diesel is in. - Starting it. When the system is bled with clean diesel, our technicians fire it up and make sure it runs smoothly. Till it runs on fresh diesel, we stay with it. It's very unusual for a car noticed early to be left with long-term damage, and normal driving starts again straight away. ## After your fuel drain: back on the road around Five Locks - Drive normally. There's nothing special to do after it's been started on clean fuel. - Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or your throttle stumbling: pull over then call us back. - Keep your documents. A hire firm, a fleet manager or an insurer may ask what was carried out. - Check the label on the petrol pump next time, not the colour of the handle. ## About Five Locks Five Locks is a suburban area situated on the riverside in Torfaen, Wales, with a mix of terraced housing and local amenities.
