If you have not turned on the engine yet, don't. A drain and nothing more is almost always what a vehicle needs while the petrol is still sitting in the tank and the motor has not yet been started, which is why it's the following few minutes that matter, not how much got in. Petrol in Diesel goes to your car wherever it has ended up in Farnsfield or the rest of Nottinghamshire, on the forecourt, by the roadside or on a driveway, and drains and flushes it there. A single call to us is sufficient: our team will tell you what follows from here. Make it right away. ## Now what? Petrol in a diesel, in order - Do not fire it up. Turned on all the same? Then don't rely on it. Diesel in a petrol car normally cannot run, so the driver stops and the wear halts with them. Petrol in a diesel? It starts. It idles. It pulls away fine, for several miles. People get that reversed. It isn't okay — that fuel system is wearing every mile you cover. - Diesel combusts, and before it ignites it greases — that injection pump, those injectors. Petrol manages only the burning. So leave the car's ignition alone too: flicking it on is often all it takes to prime the system, and priming carries petrol from the tank into just those components. - That advice supposes a diesel fuel system tolerates petrol by percentage. It won't. Put diesel on top and nothing at all is removed; what you have is a fuller tank of the same mix. And no, the grade makes no difference — super unleaded is just petrol. - A car that has not moved is the quickest one to sort out, so stay where you are if you sensibly can. Pulled up on the verge on Tippings Lane? Hazards on, and keep the car there. An odd spot suits us better than a started engine. - Before you ring, have your location. Anything next to you with a name on it, plus a postcode starting NG22 8 — that's what decides whether our van shows up or circles. - Three answers decide the whole visit: the stuff you tipped in, the rough amount involved, and whether it has been running since. Our number is 0333 366 0103. Petrol in a diesel Volkswagen Golf, sat at Bleasby since first thing? The afternoon has cost you nothing — fuel in a tank is dormant. It was the run in that pulled thinned diesel through your pump. Ring us before you move the vehicle. ## Pump-side draining for petrol in a diesel Forecourts are where this job often kicks off, and where a fair chunk of it ends. If you are still on the forecourt at Brookside Garage, that is normally where this drain gets done — our technicians work on garage forecourts all the time, with the station's agreement. Before the motor has run — a forecourt is the only setting it gets spotted. We can still deal with it where it sits, even away from the forecourt. In a car park, on a private drive or in a lay-by, the car has been started and driven there, and that sucked fuel through your filter then into the high-pressure pump, all the way from that tank. None of that is a disaster, though the flush then has to go past your tank to your lines and the filter, and the few seconds between reading the till receipt and reaching for your key are what decide that. Clear of the petrol pump, the next driver can get by — so yes, let the staff help you move the vehicle. Well worth doing. Moving it four bays does not justify cranking the engine. ## Areas our vans serve in Farnsfield These same runs get us to White Post, Edingley, Kirklington, Bilsthorpe Moor and Belle Eau Park along with Farnsfield, which is a rural village. If yours isn't on that list it does not mean we never come — there are separate pages for most places in Nottinghamshire, and the ones listed above are simply the nearest neighbours. Phone to ask rather than assuming — boundaries especially, and anywhere your phone may get wrong. That map is the patch the page spans. Roadside, forecourt, private drive, car park: the lot is territory we serve, and none of it needs your car to travel to us. Nothing alerts you, because from the driver's seat there is nothing to be warned about. The diesel BMW 3 Series will have felt completely ordinary on the way back from Farnsfield St Michael's Church of England Primary School, and they all do — which is the trap with petrol in a diesel rather than the reverse. Diesel in a petrol vehicle usually refuses to run, stopping the driver and stopping the damage with them. Petrol in a diesel fires up, idles, pulls away as though nothing had happened, and all the while the pump works without the protection its fuel is meant to supply. Tell us roughly how far, and how hard. The harder counts more. ## Roadside stops in Farnsfield The opportunity to pull in somewhere sensible doesn't come to everybody. A routine call for us and not an odd one: worked out after setting off, finished up along the verge beside Main Street or at a lay-by with the hazard lights on. Remain by the motor if it's sensible to sit inside, yet out of the vehicle when it isn't. Every mile a diesel obliges you for on petrol pulls that mixture further into your fuel system — and oblige it frequently will, which is why the motor does not get restarted to limp somewhere better. We will send our van to an inconvenient location without any fuss, and for the vehicle that's far better than pressing on. ## A couple of miles on petrol in a diesel: what next? under 10 miles from Farnsfield, the M1 is what counts now. A loss of power, a lumpy idle, some smoke: those are the signs when they arrive, instead of a tidy stop — and a misfuelled diesel will frequently get you onto it and some way along before anything seems wrong at all. Take the next exit that is safe, pull up there, and do not start the car to reposition. Long run? Anything close to the under 15 miles to the nearest city and you should suppose the lot — filter, pump, injectors, all of that arrived at by the petrol. Say that on the call, as it affects what goes in the van. Here is the entire process. Diesel needs enough body to seal the fine tolerances it goes through, and petrol takes that away. That's it. Which explains the usual Wilson's Field call — a diesel Mercedes C-Class, out there without fuss and back down on power, lumpy at idle, possibly a bit of smoke. Injection systems work hydraulically as well as chemically, and so the fuel has to hold pressure and not just burn; weakened, it bleeds past those tolerances rather than building, and delivery comes weaker, later, less even than the engine was designed about. Not a failing engine, though. Fuel that has stopped behaving like diesel. Put that right and it stops. ## Where's Farnsfield? Farnsfield is a village in Nottinghamshire, situated in the East Midlands region of England, with a population of around 2353 people. Farnsfield lies approximately 11 miles north-east of Nottingham and 116 miles north of London, at an elevation of 57 metres. Farnsfield is characterised by its predominantly detached housing stock and is surrounded by nearby villages such as White Post, Edingley, and Kirklington. Farnsfield remains a rural community with a strong sense of identity. ## What we do when our technicians arrive with you around Farnsfield - The answers alter the work, which is why we ask before pricing: what went in, how much of it, and if the motor has run. - Out flows the tainted fuel. - Fuel lines are rinsed through and your filter cleared, leaving nothing in the fuel system that started any of this. - Your system gets primed, on clean diesel. - Your engine is turned on and checked to make sure it runs smoothly on clean diesel. From there, you are ready to set off. Our engineers do all of it wherever your car has stopped, which means it never needs to go to a workshop, and when it has been spotted early, it is very unusual for there to be permanent damage. About as well as this goes, once your engine has turned: away from the pumps, receipt read, and your diesel Audi A6 left close to Farnsfield Methodist Church scarcely two streets on. Phone us, and leave the vehicle off. A short distance does really help. It was still a start and still a drive, though, so the filter and the pump have had diluted fuel through them — hence flushing your lines instead of only draining that tank. ## Farnsfield AdBlue removal is a different matter The issue isn't the same, though the first step is — never fire it up — if what got in was AdBlue rather than petrol. Petrol weakens the diesel and strips the lubrication the system depends on. AdBlue is urea dissolved in water, and in a diesel tank it leads to corrosion and build-up instead. Often the more serious of the two, AdBlue — and the full story lives on its own Farnsfield page. Both are ours to deal with. Turn off where you have stopped, and don't restart it to find somewhere better — close to Farnsfield Village Centre or anywhere at all. Clattering, an uneven idle, white smoke and a soft throttle are a wrongly fuelled diesel Peugeot 208 telling you what is wrong. ## What a petrol-in-diesel drain will cost around Farnsfield Our engineers can't put one number on this page honestly, as the job isn't one job. What moves it: - Has it been started or driven? Nothing else matters for as much. - How much of the wrong fuel went in, judged against how much your tank can hold. - AdBlue or petrol, whichever got in. - Where is it? And can a technician get to it and work there safely? The vehicle, the quantity, whether it has run — give us those and the answer comes back clear instead of as a range. Motor at home, going nowhere, nothing time-critical about it — is good for that. ## Farnsfield motorists ask us these about petrol in diesel ## I am on a forecourt around Farnsfield. Can you drain the car on the spot? A fair part of this work takes place there, so yes. Tell us which one you are at when you phone and we'll tell you if our engineers can work there. With the site's permission we attend JET and the other forecourts nearby all the time. ## How much petrol is too much for a diesel? Proportion decides it instead of litres — and more than either, whether the motor has run. Five litres in a nearly empty tank is a different matter from five in a full one — but either way, the thing that determines how much work is needed is if that mix has been sucked through your fuel system. ## I drove the vehicle after putting petrol in my diesel. Now what? Somewhere sensible, then stop, then switch off and leave it off. Driving takes the problem along — out of the tank, into the pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one really useful thing left to you isn't restarting the car. ## Fuel drains and manufacturer warranties A manufacturer's warranty survives a drain then flush done to a correct standard, which is no alteration at all. What is likelier to start an argument is a diesel that has been run on petrol. One more good reason for the motor to stay off. ## Can I just add two-stroke oil and drive home? No. Two-stroke oil is an old remedy for a distinct fault and it doesn't put back what petrol has weakened. That tank still has petrol in it later, and the pump still has to cope with it. ## Main dealers and petrol in a diesel There is no need to bring it to a franchised dealer, as our technicians drain and clean the vehicle wherever it is. ## Waiting next to it? Don't turn it on again. Already driven it? Then stop somewhere safe, switch off, then let the car stay that way. Cold, parked, going nowhere: that is the best position to be in. People fear this much more than they need to. Across Nottinghamshire and in Farnsfield: on-site fuel draining, at home or on the forecourt or at the roadside.
