Don't Start It With that tank still holding the fuel and the motor not yet run, almost every job needs only a drain, so leave your engine off. That result is decided in the minutes right after filling up, and not by the amount that got in. All over Ogmore Vale and the remainder of Bridgend, Petrol in Diesel drains the vehicle and flushes it where it is, whether at a roadside, on a private drive or at a forecourt. Our team will tell you what your next move will be. Ring us — that goes before anything else. ## What next? Petrol in a diesel, in turn - Feed a petrol motor diesel and it will usually refuse to run at all, so the driver stops there and so does the damage. Give a diesel petrol and the thing starts, it idles, it pulls away — all right for a couple of miles. Drivers have that muddled, which is the bit they get wrong about petrol in a diesel especially. So do not crank it. And once started, never depend on it: that fuel system is wearing down while you drive. - Leave the car's ignition off as well. Diesel does two tasks: it combusts, and before it ignites it lubricates that injection pump and its injectors. Petrol handles the first and not the second. Switching the ignition on is frequently enough to prime your system, which pulls that petrol out of your tank then into precisely those parts. - Do not water down it. Diesel added on top removes nothing, so all you have is more of what was already there, since percentage isn't how a diesel fuel system copes with petrol. Super unleaded? Just petrol. The octane makes no difference. - Stay put if it's safe to. Hazards on, motor off, leave the car. Wherever you have stopped — the verge on Tynewydd Row, anywhere — a tricky place for us is better than a started diesel, and nothing is quicker for us to sort out than a motor that never shifted. - Our van turning up instead of circling hinges on two things: a postcode beginning CF32 7, and whatever is closest to you with a label on it. Keep both ready before you ring. - Call 0333 366 0103. Tell us what was put in, about how much, and also whether the motor has run. These three replies shape the entire job. Petrol in a diesel Volkswagen Golf, sitting outside Ton Pentre since breakfast? The afternoon has cost you nothing — fuel in a tank is inert. It was the trip in that pushed weakened diesel through the pump. Phone before you fetch it. ## Can petrol be drained out of a diesel on a forecourt? Plenty of this job starts at a pump, meaning a fair chunk of it gets completed at one. Our technicians work on petrol station forecourts routinely, with the owner's permission, so if you're still at the nearest petrol station that is typically where this drain happens. At the forecourt, this gets stopped with your engine never fired, and nowhere else manages it. Everywhere else — a car park, a driveway, a lay-by — the vehicle was switched on and moved to get there, which means fuel was sucked from that tank, through the filter and into the high-pressure pump. That's not a disaster, and our technicians can still deal with it where it sits. It does mean the lines and your filter need flushing as well as your tank, and that is settled by the few seconds between checking the till receipt and going for the keys. The staff will normally happily move the car clear of the petrol pump so the next customer can get through. That's worth doing. Moving the car four spaces doesn't warrant firing the motor. Each start primes the fuel system and sucks more of the mix out of your tank and towards the pump — which is why a vehicle shuffled twice into a better space has silently grown into a worse job than one left precisely where it stopped. So when our engineers can't work alongside the diesel Renault Clio, we shift it without running it. None of that is fussiness about a couple of seconds of running. Car parks like the one outside Co-op Food our technicians visit often, and your fuel is seldom the complicated part: that bay is. Motors either side, a trolley shelter behind, sometimes a height barrier at the entrance settling whether a technician gets to you at all. Tell us how hemmed in you are, and which way your car points. ## Coverage in Ogmore Vale The same runs bring us to Wyndham, Price Town, Nant-y-moel, Lewistown and Tylagwyn along with Ogmore Vale, which is a village. If yours is not on this list it doesn't mean we do not come — there are pages for the majority of places in Bridgend, and the ones listed above are just the closest neighbours. Phone and ask rather than presuming — borders particularly, and anywhere your phone may struggle with. This map outlines the patch the page includes. Your car does not need to come to us. We work over the lot — roadside, forecourts, driveways, car parks. How far, and how hard? The second of those matters more than the first, and so have both prepared. The Audi A4 will have felt perfectly usual on the way back from the local primary school — they all do, and that's the trap. Diesel into a petrol motor usually won't run at all: the person stops, and so does the damage. Petrol into a diesel fires up, idles, drives off like nothing happened, while your high-pressure pump gets on with its work minus the protection the fuel should be giving it. No warning comes, since behind the wheel nothing seems wrong. ## Broken down on the roadside around Ogmore Vale Not everybody gets a chance to pull in anywhere sensible. Set off, then twigged? Ended up by the verge on Llywelyn Street, or stuck in some lay-by with the hazards flashing? That is a normal call here. Not a rare one. Okay right there? Sit beside it. Not safe? Step out and away from it. Every mile a diesel obliges you for on petrol pulls the mixture further into your fuel system — and oblige it frequently will, which is why your motor does not get restarted to limp somewhere handier. We will send the van to an inconvenient spot without any trouble, and for the vehicle that's far better than carrying on. ## Driven it already? Stop, then see this Here is where the M4 matters, under 5 miles out of Ogmore Vale. It will frequently take you onto it, and some way along, before you feel a thing. Then it's some smoke, a lumpy idle and power ebbing away — not a clean stop. Misfuelled diesels rarely give you one of those. Pull off at the first safe exit, switch off, and don't start it to move it. It alters what our technicians bring, so tell us when you call: on a longer drive — anything close to the under 25 miles to the closest city — take it the mixture has been through your filter, the pump and your injectors. ## Ogmore Vale itself Ogmore Vale is a small village in Bridgend, situated on the banks of the River Ogmore in south Wales. Ogmore Vale has a population of around 1196 people and is characterized by its predominantly terraced housing. Ogmore Vale is located near other villages such as Wyndham, Price Town, and Nant-y-moel, and is approximately 17 miles from the city of Swansea. Ogmore Vale sits at an elevation of 151 metres above sea level, in a scenic riverside setting. ## What we do when our technicians arrive with you around Ogmore Vale - The answers alter the work, which is why we ask before giving a price: what went in, how much of that, and whether your engine has run. - We empty your tank of the tainted fuel. - What is left in your system shouldn't be what started the issue, and so the fuel lines get cleaned and the fuel filter cleared. - The system gets bled, on new diesel. - It is fired up with clean diesel in it, and we make sure that it's running properly. That has the car ready to drive away. We do all of it wherever the vehicle has ended up, which means it never needs to go to a workshop, and when it has been spotted soon, it is very uncommon for there to be long-term damage. Why we are direct about not driving on: the pump sits before the injectors, and so whatever a worn-out pump sheds moves downstream with your fuel. Leave the Mercedes A-Class close to Calvary Baptist Chapel and ring us. ## Ogmore Vale AdBlue removal is a different job AdBlue rather than petrol? Then the opening rule is unchanged — the motor remains off — while the fault beneath it's a different one altogether. Diluted diesel, and no lubrication left for the fuel system that relies on it. That's petrol. AdBlue is urea in water, and in a diesel tank it leads to corrosion and build-up in its place. Our technicians cover both, and AdBlue removal in Ogmore Vale has its own page with the details — including why it is usually the more serious of the two. ## How much is a petrol-in-diesel drain in Ogmore Vale? We cannot put one price on this page truthfully, as the job is not one job. What shifts it: - Has it been run or driven? Nothing else counts for as much. - How much of the wrong fuel was put in, compared with how much your tank takes. - The type of fluid in the tank, unleaded or AdBlue. - Access: the vehicle's position, and whether working on it there's sensible for our van. The vehicle, the amount, whether it has run — give us those and the answer comes back straight instead of as a range. Car at home, going nowhere, nothing urgent about it — is fine for that. Your filter, the lines, the pump and its rail: that's where the blend is once a diesel has run, and it doesn't come back out with the tank contents. So your tank is not where most of the trouble sits by this point, and a diesel Ford Fiesta that got by St Cein needs the system cleared rather than drained. ## Petrol in diesel: common questions around Ogmore Vale ## I am on a forecourt around Ogmore Vale. Can you drain the car here? Yes, and it's where a large portion of this work gets done. Consent from the site is the condition. Given that, a forecourt like Blackmil Service Station is somewhere we're often enough, along with the rest of them locally — so name yours on the phone and you will hear if working there is possible. ## How much petrol in a diesel is too much? Whether your engine has run counts far more, though the proportion matters too, rather than the litres. Five litres in a nearly empty tank is a separate matter from five in a full one — but either way, the thing that determines how much work is required is if that blend has been drawn through the system. ## Already driven it with petrol in your diesel? What now? Stop sensibly. Off. Nothing after that. Driving is what moves the issue from that tank into the pump and injectors — but it's recoverable far more commonly than motorists assume, and the single most valuable thing you can do now is not restart the vehicle. ## Is a fuel drain going to void my warranty? A drain and flush carried out properly isn't an alteration and doesn't void a manufacturer's warranty. Another reason to leave it turned off: running a diesel on petrol is the thing more likely to cause an argument with one. ## Adding two-stroke oil, then driving home No. Two-stroke oil is an old remedy for a separate problem and it doesn't put back what petrol has weakened. Your pump still has to cope with it, as the tank still has petrol in it afterwards. ## Main dealers and petrol in a diesel Wherever the vehicle is, our technicians drain and clean it there, so a trip to the main dealer does not come into it. ## Is the vehicle still with you? Do not switch the car on again. Switch it off somewhere safe then keep it off, if you have already driven it. This is recoverable from much more commonly than people fear, and a still, cold motor is the best position to be in. Emptying misfuelled cars, Ogmore Vale and the rest of Bridgend, wherever they are.
