Engine off. Keep it that way — no moment on, no shifting it at all. Cleared then rinsed, just where it sits: that's normally all an unrun diesel with petrol in it takes. Whether it remains that straightforward depends on the minutes ahead more than on everything else. Here's the order of things from now, anywhere you are in Saron. ## Motor off: minute one with petrol in a diesel In this order, all before everything else: - Take the keys out. Even your ignition on its own can prime the fuel system, pulling petrol out of the tank to precisely the components it harms, so leave the car off entirely. - Topping up with diesel seems like it dilutes the problem. It doesn't: nothing gets out, and the tank just carries more of the same. - Make your car simple to see before anything else — hazard lights on — if there's traffic going past anywhere near you. - By hand, not on your engine: that's how it leaves the pump. Ask the forecourt attendants to help you roll, however short the mileage. - Hold on to the till receipt. It says which fuel was put in plus roughly how much, which is the first thing we'll ask. Realised on the move? Get off at the next exit if you're on the M4, under 5 miles from Saron, and pull over somewhere safe — not at the services farther on. Stage one starts after that. ## Saron fuel drain: has the motor run yet, or not? Everything after this point depends on one answer. If it has never been started: - All the petrol remains inside that tank, and just there. - Where the car sits is normally where the work is done: a drain, then a flush. - Stage one matters for exactly this reason: it's the best spot to be in. If it's been started, even for a second: - The fuel lines and the filter now hold petrol pulled out of your tank. - On a bigger run it has reached the high-pressure fuel pump and the fuel injectors. - The further it went, the larger this job — the fuel lines, the fuel filter, and sometimes more besides. Petrol does not lubricate. Diesel does, protecting your pump and injectors as it flows through, which is why the line sits where it does. Nothing is damaged by petrol that is only resting in a tank. The components that move it are wearing the moment petrol is being pumped. ## Calling about petrol in a diesel from Saron: what to have ready Whether the van circles or finds you depends on a little planning. - Where you are. A postcode beginning SA18 3 is the best start. - Wherever you have pulled up, the road's name is useful — whether that's Yr Hafod or somewhere else — and so does the name of a car park. - Name a car park by what it serves — the one outside Tycroes Supermarket, for instance — and it is far easier to find. - Make and model of the vehicle, and the fact it's a diesel. - Which went in counts: AdBlue is a separate job from petrol, plus Saron has a page for it. So tell us. - How long the nozzle was in, or the litres on the receipt — whichever gives us how much. - Whether it has run. Then if it has, how far and how hard. - The owner may have to approve the work under some hire or company agreements — which is why it's quicker to settle whose motor it is before our technicians get there. Phone 0333 366 0103 once you have got that together — or, if the car is at home, going nowhere, use . ## Saron fuel drain on its way? While you wait The wait is where well-intended help does the damage. Stick to these. - Your safety comes before your car. Somewhere dangerous? Get away from the traffic and wait away from it. Safe where it stands? Stay with it. - A helpful passer-by does not start it. Nor does anyone wanting to check it still works, or moving it a couple of yards. - Additives stay in your boot. Injector cleaner and two-stroke oil draw none of the petrol out once more. - Siphoning petrol into a can at the roadside is hazardous — and it also leaves whatever fuel has already gone beyond your tank. Do not try a home-made drain. - Not for your radio, not for your windows: the ignition remains off. ## Step by step: the fuel drain when our van arrives - Three questions. What got in, how much, and if it has run. Those answers shape the job, which is why the price comes after them but not before. - Next your tank is cleared, and the contaminated fuel comes out. - Petrol that has moved beyond the tank sits in your lines if it ran, and the lines are rinsed to shift it. - Then the filter: changed where there is a workable one, cleared where there's not. - Fresh diesel in, and your system primed. - Starting up. After the fuel system is bled with fresh diesel, our engineers start it and make sure it runs correctly. The vehicle has new diesel running through it before our engineers head off. If it has been noticed soon, long-term damage is very rare, and your car returns to normal driving at once. ## After the fuel drain is done: driving in Saron once more - Started on fresh diesel, it needs nothing special of you. Just drive normally. - Pull over and call us back if anything seems wrong early on — a light on the 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. - The handle's colour isn't the guide to go by next time — the label on the petrol pump is. ## About Saron, briefly Saron is a small village in Carmarthenshire, situated on the banks of a river at an elevation of around 102 metres.
