If you have not fired up the engine yet, do not. A drain and nothing else is nearly always what a motor needs while the fuel is still in your tank and the engine has not been started, which is why it's the coming few minutes that count, not how much was put in. Petrol in Diesel travels to the car wherever it has come to rest in Birkenshaw or the rest of West Yorkshire, on the forecourt, by the roadside or on a driveway, and drains and flushes it there. Our technicians shall show you what the next stage is. Contact us — it comes before all else. ## What to try next about petrol in a diesel - As you drive, your pump and your injectors wear. That is why you don't fire it up, and why you never depend on it once it has started. The catch about petrol in a diesel specifically — the part people get wrong — is that it drives off fine for the first mile or two. Diesel in a petrol engine usually can't run at all, which stops the person and stops the harm with them. This one lets you drive on. - Leave the car's ignition off as well. Diesel does two jobs: it combusts, and before it ignites it greases your injection pump and its injectors. Petrol does the first and not the second. Turning the car's ignition on is often sufficient to prime that system, which pulls the petrol out of the tank and into exactly those parts. - Don't tip diesel on top to weaken it. A diesel fuel system doesn't accept petrol by percentage as that guidance presumes, and topping up clears nothing — it merely hands you a larger tank of the same mix. The octane makes no difference either: super unleaded is simply petrol. - We would rather drive to a difficult spot than have it started — so if you sensibly can, stay still. Nothing is quicker to deal with than a vehicle that hasn't moved. On the verge on Town Street, that means hazards on and keep the car. - Have your location ready before you phone. A postcode starting BD11 2 and whatever is next to you with a sign on it is the difference between our van turning up and the van circling. - What went in, roughly how many litres, and also if the motor has run — those three details settle the whole visit. Call 0333 366 0103 and tell us. The high-pressure fuel pump did that morning run labouring on a fluid that had lost most of the protection it is designed around. Diesel greases that pump, and the injectors with it, before any of your fuel ignites; petrol does the burning and none of the lubricating. So take a diesel Volkswagen Golf, topped up at quarter past eight, driven in to work, and parked standing at Low Moor till it dawns on you around eleven. Three hours of sitting have changed nothing about it. The few miles before that changed a lot, which is why the thing we put to you is about distance rather than hours. Ring us. Keep the car precisely where it sits. ## Removing petrol from the diesel at the forecourt Plenty of this job begins at a forecourt, meaning a fair chunk of that ends up completed on site. If you're still at the forecourt at Whitehall Filling Station, that is generally where this drain takes place — we work on petrol station forecourts routinely, with the owner's consent. No place other than the forecourt can this be caught with your motor still unrun. Our technicians 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, your car has been switched on and moved there, and that drew fuel through the filter and into the high-pressure pump, all the way from that tank. None of that is a calamity, though the flush then has to go past the tank to the fuel lines and your filter, and the few seconds between reading the till receipt and reaching for your key are what decide that. Attendants will normally chip in pushing it away from the pump, which lets the next driver get through. Accept the help. Four car lengths is not worth the risk. ## Parts our team cover near Birkenshaw Birkenshaw is a village, so our team go out to it and to the villages around it on the usual trips: East Bierley, Swincliffe, Westgate Hill, Birkenshaw Bottoms and Toftshaw Moor. If yours isn't on that list it does not mean we don't come — there are dedicated pages for most places in West Yorkshire, and the ones mentioned above are just the nearest neighbours. Close to the border, or somewhere a satnav can't find? Phone to enquire instead of presuming. Look at our map for the area shown here. We work roadside, on forecourts, on driveways and at car parks across all of that, and your vehicle doesn't need to move to us. Move the car out of that gateway and sort it out later — that is what a passer-by will say, and it is wrong. Sitting on the zig-zags outside Birkenshaw Church of England Voluntary Controlled Primary School, a misfilled diesel Skoda Octavia is a hassle and nothing worse. Fired up three more times for good manners, it's no longer a tank issue but a fuel system one, as priming happens with every start and more petrol goes through the fuel filter towards the pump. Let everyone moan. Phone us. ## Kerbside call-outs across Birkenshaw Not everyone finds a sensible place to pull in. Set off, then realised? Landed along the verge on Croft Bank, or stuck in some lay-by with the hazards flashing? That is a common call here. Not an unusual one. Remain beside the motor when it's wise to be there, yet out of the vehicle when it's not. Every mile a diesel obliges you for on petrol pulls that mixture further into your fuel system — and oblige it often will, which is why your engine doesn't get restarted to limp somewhere better. Our van heading to a tricky place is no trouble for us, and it is far better for the vehicle than pressing on. Here's what a job in the car park at The George typically looks like. Our technicians arrive at your car, ask what got in, about how much, and whether the motor has run since — those three replies determine most of the work. Then the polluted mixture comes out of that tank, the lines get cleaned, and the filter comes off where your Audi A4 has a replaceable one. New diesel goes in and the system is bled. Then we fire it up, confirm it runs correctly, and you drive away. ## Some miles on petrol in a diesel: now what? under a mile out of Birkenshaw, the M62 is what counts now. A drop in power, a lumpy idle, smoke: those are the signs when they arrive, rather than a clean stop — and a misfuelled diesel will often take you onto it and some way along before anything seems wrong at all. Take the next junction that is safe, stop there, and never start the car to move it. Long trip? Anything close to the under 5 miles to the closest city and you should assume the lot — filter, pump, injectors, all of that got to by the petrol. Say that on the phone, since it affects what goes in our van. ## About Birkenshaw Birkenshaw is a village in West Yorkshire, situated near the River Aire and close to the cities of Bradford and Leeds. Birkenshaw sits at an elevation of 185 metres, with the surrounding landscape featuring a mix of urban and rural areas. Birkenshaw is characterised by its predominantly terraced housing stock, reflecting its history of industrial and residential development. Birkenshaw is located near several other small villages, including East Bierley and Swincliffe. ## What happens when we get to you around Birkenshaw - We ask first, price after. What got in? How much? Has your engine run? Those responses alter what the work actually is. - Out comes the polluted fuel. - Fuel lines are flushed through and your filter cleaned, leaving nothing in your system that created any of this. - Priming follows, once clean diesel is in. - The engine is turned on and checked to be sure it runs smoothly on clean diesel. After that it's ready to drive away. Everything is done where your car is, so it never needs to be taken to a garage, and when it has been spotted quickly, permanent damage is very unusual. ## AdBlue in the diesel tank by mistake, in Birkenshaw? If what went in was AdBlue rather than petrol, the opening step is the same — do not crank it — yet this problem isn't. Petrol thins your diesel and strips the lubrication the system relies on. AdBlue is urea in water, and in a diesel tank it brings corrosion and residue instead. Often the more significant of the two, AdBlue — and the details sits on its own Birkenshaw page. Both are ours to deal with. Petrol in a diesel does its harm as a proportion, which is the reason we ask at all: the same few litres resting in a nearly empty tank make a far stronger blend than they would in a full one. And petrol is rated on how well it withstands igniting under pressure — the opposite of what a diesel wants — so a stronger mix rattles more, smokes more, goes flatter. None of which means you need an answer prepared. Almost nobody knows how full that tank was in a vehicle collected two days ago, and our technicians work that out on site. Do call the hire or company firm first, though: some contracts want them to sign off the work, and that is far quicker settled before than after. Then ring us about the Mercedes E-Class by St. Paul's Church. ## How much is a petrol-in-diesel fuel drain in Birkenshaw? One number wouldn't be fair here, as this is not one job. These are the things that move it: - Has it been started or driven? Nothing else counts for as much. - How much of the wrong fuel went in, weighed against how much that tank takes. - Whether it's unleaded or AdBlue. - Where is it? And can our van reach it and work there safely? Tell us what your vehicle is, how much got in, and whether the engine has run. A clear answer comes back, not a range. For the vehicle at home that is going nowhere and is not urgent, is fine too. By now your tank is the least of it. Run a diesel and that mixture goes into the filter, into the lines, into the pump, into the rail — and none of that leaves with the tank contents. A diesel BMW 5 Series that made it close to East Bierley Community Sports Association needs its system cleared. Draining isn't the same thing. ## Questions we get about petrol in diesel in Birkenshaw ## I'm on a forecourt in Birkenshaw. Can you drain the vehicle here? Yes, and it's where a big share of this work takes place. Often, provided the site agrees: Shell, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether our technicians can work in that place is something our engineers answer on the spot. ## Is there a safe quantity of petrol in a diesel? Litres are not the yardstick. Proportion is, and much more than either, it counts whether anything has been run. What decides how much work is required is whether that mix has been drawn through your fuel system — since although five litres in an almost empty tank is a distinct situation from five in a full one, either way that's the question. ## Already driven it with petrol in the diesel? Now what? Somewhere safe, then stop, then turn off and keep it off. Driving shifts the issue 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 valuable thing left to you isn't restarting it. ## Is a fuel drain going to void my warranty? It is not a change, and so a drain and flush carried out properly does not invalidate a manufacturer's warranty. Running a diesel on petrol is the thing more likely to cause a disagreement with one, which is another good reason to leave the vehicle turned off. ## Could I put some two-stroke in and just drive? No. It belongs to a different problem from a bygone era, and petrol has thinned something no oil of that kind replaces. Your tank still has petrol in it later on, and your pump still has to live with it. ## Do I need a main dealer for petrol in a diesel? No. We drain and clean your car wherever it is, so there's no need to bring it to a main dealer. ## Still with your car? Turned off is how the car stays. Turn it off somewhere safe and leave it off, if you have already driven it. A parked, cold motor is the best place to be in, and this is recoverable from a lot more commonly than motorists expect. Throughout West Yorkshire and around Birkenshaw: mobile fuel draining, at home or on the forecourt or at the roadside.
