Don't Start It Petrol in Diesel drains and cleans wrongly fuelled cars where they stand, on the forecourt, at the roadside or on a private drive, across Belleeks and the remainder of County Armagh. The first thing to do is not to fire up your engine. When the motor has not run and the petrol is still inside the tank, a fuel drain is nearly always all it needs, and the next few minutes settle that, not how much was put in. One ring to us will be enough: our team can tell you what happens from here. Make that right away. ## What next? Petrol in a diesel, in order - Don't fire it up. Turned on regardless? Then never believe it. Diesel in a petrol motor generally can't run, so the driver stops and the harm halts with them. Petrol in a diesel? It starts. It ticks over. It moves off happily, for several miles. Most people get that backwards. It isn't fine — your fuel system is grinding every mile you do. - Switching your ignition on usually primes the system, and priming is what moves petrol out of that tank then into your pump and injectors. Those are the components diesel keeps protected on its way through, before it ignites. Petrol manages the burning and none of the oiling. Leave the car's ignition be. - Do not dilute it. Diesel put on top removes nothing, so all you get is more of what was already there, because percentage isn't how a diesel fuel system handles petrol. Super unleaded? Just petrol. The octane makes no difference. - Sit tight if it's safe to. Hazards on, motor off, keep the vehicle. Wherever you have stopped — the verge on Dunskey Street, anywhere — a difficult place for us beats a started motor, and nothing is easier for us to handle than a motor that never moved. - Keep your position ready before you dial. A postcode that starts BT35 7 and whatever is next to you with a sign on it is the difference between a van showing up and our van circling. - Three answers decide the whole job: the fuel you tipped in, the rough measure of it, and whether it has been going since. The number is 0333 366 0103. The journey back would roughly double it, for no reason at all. One commute has already put a real quantity of petrol-thinned diesel through the high-pressure pump of that Renault Megane. So keep the car where it sits. Phone us from the platform if that's quicker — nobody needs you hovering over your car outside the nearest station whilst our engineers get on, and tonight trumps finding out on Monday. ## Pump-side drains for petrol in a diesel A fair chunk of the work gets done at a pump, because that's where it mostly begins. We work on station forecourts all the time, with the owner's consent, and so if you are still at the nearest petrol station that is typically where this drain gets done. At the forecourt, this gets halted with your motor never started, and nowhere else manages that. The few seconds between reading the receipt and going for your key determine how much requires flushing. Anywhere other than a forecourt — a car park, a private drive, a lay-by — the vehicle was fired up and moved to get there, so fuel was drawn from that tank, through your filter and into your high-pressure pump. That means your lines and your filter need rinsing as well as your tank. It's not a disaster, and our technicians can still deal with it where your car stands. Out from the petrol pump, the next driver can get through — so yes, let the attendants help you move the vehicle. Worth doing. Starting the car just for four car lengths? Not a chance. ## Belleeks plus the areas beside it Belleeks is a small village, so we go out to it and to the places around it on the same journeys: Lislea, Dorsey, Camlough, Mullaghbawn and Whitecross. If yours is not on the list that does not mean we never come — there are pages for most locations in County Armagh, and the ones mentioned above are just the nearest neighbours. Contact us to ask rather than assuming — boundaries above all, and anywhere your phone can get wrong. The map is the area the page covers. Every bit of it is territory our technicians serve: a roadside, a forecourt, a driveway, a car park. You do not bring the car anywhere. Hazards on. Ignition off. Call us. It is twenty to nine at the gates of the local primary school, you are late, and the till receipt says unleaded — and although three miles in your Skoda Octavia seems like nothing, fuel gets delivered on demand, and a rushed dash demands plenty of that. ## Roadside call-outs across Belleeks Some people get no suitable place to pull in at all. If you worked it out after setting off and landed on the verge of South Crescent, or in a lay-by somewhere with the hazard lights on, that's a routine call for us rather than a rare one. Whether you stay by the motor or stand clear of it depends on whether staying in it feels safe. It will usually oblige. A diesel running on petrol limps along quite willingly, and that is the catch: fire it up to reach somewhere safer and the mix goes further into the system with every mile driven. Driving on does the car far more harm than our van heading out to an inconvenient location, and that's no bother for us. ## Some miles on petrol in a diesel: what now? Your M77 is the road which matters now, and lies over 50 miles from Belleeks. It will frequently take you onto it, and some way along, before you spot a thing. Then it's some smoke, a rough idle and power draining away — not a neat stop. Misfilled diesels seldom give you one of those. Take the next junction that's safe, stop there, and don't start the car to move it. On a longer drive — anything near the under 10 miles to the nearest city — take it the contamination has been through the fuel filter, the pump and the fuel injectors, and mention it when you phone. It changes what our technicians bring. Pull in somewhere sensible, turn off and call us. Fine on the way out to the green space at the edge of the village, flat on the way back? Then look at the tank. Petrol weakens diesel; thinner fuel seeps past the close-fitting parts that build injection pressure; and the farther your diesel Nissan Qashqai travelled, the less of that pressure it held. ## Belleeks itself Belleeks is a rural locality in County Armagh, situated inland at an elevation of 262 metres, approximately 5.5 miles from Newry. Belleeks is characterised by its detached housing and rolling countryside, with nearby places including Lislea, Dorsey, and Camlough. Belleeks has a population of around 879 residents, and is located about 322.5 miles from London. ## What happens when our technicians arrive with you in Belleeks - Our technicians ask first, quote after. What got in? How much? Has the motor run? Those answers shape what the work really is. - The tank gets cleared of everything. - What is remaining in the system should not be what caused the issue, so the fuel lines get flushed and the filter cleared. - Bleeding your system follows, once new diesel is in. - When it's turned on, we make sure it runs correctly on clean diesel. Then it's ready to set off. Permanent damage is very unusual when it has been noticed soon, and as all of this is done where the vehicle is, it never needs to go to a garage. ## AdBlue in your diesel tank by mistake, in Belleeks? If what got in was AdBlue instead of petrol, the opening step is unchanged — don't crank it — yet this issue is not. Diluted diesel, and no protection left for the system that relies on it. That's petrol. AdBlue is urea dissolved in water, and in a diesel tank it brings corrosion and build-up in its place. Our technicians cover both, and AdBlue removal in Belleeks has its own page with the details — including why it's frequently the more serious of the two. Hire car? Company car? Phone them before us. Some contracts want the firm to sign off the work, and that is much faster dealt with up front than later on. Then call us about the Dacia Duster, the diesel one, near a street just off the centre. Do not worry that you can't say how full that tank was — nearly no one can two days into a motor, and it's something our engineers work out on site. The reason for asking: harm from petrol in a diesel is a matter of proportion. A couple of litres in an almost empty tank make a far stronger blend than in a full one, and petrol is built to resist the very thing a diesel needs of that, which is igniting when compressed. Stronger blend, more knocking, more smoke, flatter throttle. ## Budgeting for a petrol-in-diesel drain in Belleeks What moves the price is laid out below, as this job is not one job and we can't honestly put a single figure on this page. - Has it been run or driven? Nothing else counts for as much. - Wrong fuel in, against what your tank holds — that ratio. - Which was put in: petrol or AdBlue. - Where is it? And can our van reach it and work there sensibly? The car, the quantity, whether it has run — give us those and the answer comes back straight instead of as a range. If it's not time-critical — the vehicle is at home and going nowhere — works too. It got a few streets and stopped. The throttle went soft, your idle turned lumpy, and the diesel BMW 5 Series is now sitting by the far end of the built-up part. That deadness is your fuel failing to build pressure correctly instead of the motor failing — and as there is no warning for it, motors in that position usually get driven a second time before anyone rings. Do not. Switch it off and phone us. ## Belleeks drivers ask us these about petrol in diesel ## I am on a forecourt around Belleeks. Can you drain the vehicle on the spot? A fair share of this work takes place there, so yes. Permission from the site is the condition. Given that, a forecourt like another forecourt nearby is somewhere we are frequently, along with the rest of them locally — so name yours on the call and you will hear whether working there's possible. ## Is there a sensible quantity of petrol in a diesel? Ratio decides it instead of litres — and more than either, whether your motor has run. What decides how much work is required is if that mixture has been drawn through the system — because even though five litres in a nearly empty tank is a distinct matter from five in a full one, either way that is the question. ## I put petrol in my diesel and drove the car. Now what? Stop somewhere sensible, switch off, and leave the car off. Driving takes the problem along — out of the tank, into the pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one truly useful thing left to you is not restarting the car. ## Is a fuel drain going to void my warranty? A manufacturer's warranty withstands a drain and flush done to a proper standard, which is no change at all. What's likelier to start a dispute is a diesel that has been run on petrol. One more reason for the motor to stay off. ## Could I put some two-stroke in and just drive? What petrol has diluted isn't put back by two-stroke oil, which is an old fix for a distinct fault. So no. Petrol stays in that tank later on, whatever else goes in, and the pump gets no reprieve from it. ## Does petrol in a diesel have to go to a main dealer? Wherever the vehicle is, our engineers drain and flush it there, so a drive to the main dealer does not come into it. ## Still with the vehicle? Don't switch it back on. If you have already driven it, pull in somewhere sensible, turn it off then leave it off. This is recoverable from far more commonly than drivers fear, and a still, cold car is the best place to be in. Clearing misfilled motors, Belleeks and the rest of County Armagh, wherever they are.
