Petrol in a diesel that hasn't been run is typically a drain and a flush, done where your vehicle stands, and what happens in the coming few minutes decides that far more than anything else. Below is the sequence from this point, anywhere around Poundffald you happen to be. ## Minute one: petrol in a diesel, motor off Before anything else, the following — following this order. - Priming your fuel system pulls petrol from the tank toward the components it damages, and turning your ignition on can be enough to do that. So the keys get taken out, and the ignition remains off altogether. - No diesel on top. More fuel in removes none of that petrol — it just leaves you with extra of the same blend. - Make the vehicle easy to see before anything else — hazard lights on — if there is moving traffic anywhere near you. - By hand, not on the motor: that's how it leaves the petrol pump. Ask the forecourt attendants to help you push, however short the distance. - Keep your receipt. It shows which fuel was put in plus roughly how much, which is the first thing we'll ask. If you were still on the move when you realised, pull over somewhere sensible instead of pushing on for the services — on the M4, under 5 miles from Poundffald, that means the next junction. Stage one follows. ## Every Poundffald fuel drain starts here: has the motor run? What happens after this turns on one answer, and only one. If the engine hasn't run at all: - The petrol sits inside that tank, and only there. - Normally it's emptied and flushed just where the vehicle stands. - Step one counts for exactly this reason: it's the best spot to be in. If the motor has been run, even briefly: - Petrol has been drawn out of your tank, past the fuel filter and into your lines. - On a longer run it has got to the high-pressure pump as well as the injectors. - Flushing your lines, your filter sorted, occasionally more: the job expands as the mileage does. Petrol doesn't lubricate. Diesel does, oiling the pump and injectors as it flows through, which is why the line falls where it does. In your tank, left alone, petrol harms nothing. Petrol being pumped is grinding down the parts that move the vehicle. ## What to have ready when you call about petrol in a diesel from Poundffald Prepare a little, and the van finds you instead of circling. - The ideal start is a postcode — one beginning SA4 3 — for where you have stopped. - A road name helps: Bryn Hir, say, or whichever street you have stopped in. A car park works too. - Describe a car park by what it serves — the one at CKs Supermarket, for example — and it is much easier to find. - Make and model of your vehicle, and the fact it is a diesel. - What went in. Petrol, or AdBlue. AdBlue is a different job with its own page for Poundffald, and so tell us which. - How much. Litres from your receipt, or how long the nozzle was in the filler. - Has it run? If so, say how far it went, and how it was driven. - Whose car it is. Some hire or company contracts want the owner to approve the work, and that is quicker settled before we turn up than after. Ring 0333 366 0103 once you have got that together — or, if the vehicle is at home, going nowhere, use . ## Whilst you wait for a fuel drain around Poundffald Stick to these: well-meant help does the harm during the wait. - Your safety comes before your car. Somewhere unsafe? Get away from the traffic and wait away from it. Fine where it is? Stay with it. - A kind passer-by does not start it. Nor does anyone checking it still works, or moving it a few yards. - None of it takes the petrol back out — not two-stroke oil, not injector cleaner, not something from your boot. So no additives. - A DIY drain misses your fuel that has already gone beyond that tank, and siphoning petrol by the road is dangerous besides. - Leave your ignition off — the windows and your radio included. ## The fuel drain, step by step, once the van arrives - The quote comes after three questions, not before them — what got in, how much, and whether it has run — since the answers shape this job. - Emptying it is how that mixture gets taken from that tank. - The lines are cleaned. If it ran, that petrol has moved beyond your tank, and the lines are holding it. - Then your filter: changed where there is a serviceable one, cleared where there's not. - Clean diesel goes in, and your system is primed. - Starting it. When the system is bled with fresh diesel, we fire it up and check it runs correctly. We wait until it's running on clean diesel. Long-term damage is very rare if it has been caught quickly, so the car can go right back to normal use. ## Back on the road around Poundffald after the fuel drain - Drive normally. There's nothing unusual to do once it has been started on fresh fuel. - Pull over and ring us back if anything looks wrong early on — a light on your dash, smoke from your exhaust, an idle that is lumpy, or a throttle with a dead spot. - The work may come up later with a hire company, an insurer or a fleet manager. Keep the paperwork. - Check the label on the pump next time, not the colour of the handle. ## About Poundffald and where it is Poundffald is a suburban area situated on the outskirts of Swansea, with a mix of detached housing and scenic views of the surrounding coastline.
