Don't Start It Petrol in Diesel drains and cleans misfuelled vehicles where they are, on the forecourt, by the roadside or on a private drive, throughout Littledean Hill and the rest of Gloucestershire. The very first thing to do is not to turn on the engine. When the motor has not yet been started and the fuel is still inside the tank, a tank drain is almost always all it takes, and the following few minutes decide that, not how much went in. One ring to us will be plenty: our team shall tell you what follows after this. Try that right away. ## What next? Petrol in a diesel, in order - Feed a petrol motor diesel and it will normally fail to run at all, and so the person stops there and so does the damage. Give a diesel petrol and the car starts, it idles, it moves off — fine for a few miles. People have that muddled, which is the bit they get wrong about petrol in a diesel in particular. So never start it. And if started, don't trust it: your fuel system is grinding whenever you drive. - Diesel ignites, and before it combusts it greases — that high-pressure fuel pump, its injectors. Petrol does only the burning. So leave the ignition off as well: switching it on is usually enough to prime that system, and priming moves petrol from the tank into precisely those parts. - Don't tip diesel on top to dilute it. A diesel fuel system doesn't handle petrol by percentage as that guidance presumes, and topping up gets rid of nothing — it just leaves you a fuller tank of the same mixture. The octane makes no difference either: super unleaded is simply petrol. - We'd rather get to a difficult place than have it started — so if you reasonably can, stay still. Nothing is quicker to handle than a vehicle that has not shifted. On the verge on York Road, that means hazards on and leave the vehicle. - The van turning up instead of circling depends on two things: a postcode that starts GL14 2, and whatever is closest to you with a sign on it. Have both ready before you dial. - Three answers settle the full call-out: the stuff you tipped in, the rough quantity of it, plus whether anything has been going since. Our number is 0333 366 0103. ## Forecourt draining for petrol in a diesel The work begins at the pump, usually. Regularly the job finishes there too. If you're still at the forecourt at EG on the move, that is normally where this drain takes place — our technicians work on petrol station forecourts routinely, with the site's agreement. Nowhere else but the forecourt can the mistake be caught with the engine still unrun. Everywhere else — a car park, a drive, a lay-by — the vehicle was started and driven to get there, which means fuel was pulled from that tank, through the fuel filter and into the high-pressure pump. That's not a calamity, and we can still deal with it where it stands. It does mean the lines and the filter need rinsing as well as your tank, and that is determined by the few seconds between checking your receipt and reaching for your key. The staff will usually happily wheel the vehicle away from the pump so the next motorist can get by. That is worth doing. Shifting it four lengths doesn't merit cranking it. If you have put petrol in your diesel Renault Megane in Littledean Hill and you're now stranded outside Tesco with a boot loaded with shopping, phone. Never crank it a second time to exit the bay. We'll come out to you, drain that tank, purge your fuel lines then put fresh diesel in so you can get home. A mile or so at light throttle pulls hardly any diesel, which is why such jobs tend to be the easy ones. ## Littledean Hill plus the towns near it Littledean Hill is a residential suburb, and so our technicians go out to the town and to anywhere around it on those same rounds: Collafield, Double View, Cinderford, Mount Pleasant and Littledean. Not on that list? That says nothing. The places above are only the closest few, and most places in Gloucestershire have a page of their own somewhere on our site. Phone to enquire rather than guessing — county lines above all, and wherever your phone might struggle with. The patch the page includes appears on this map. Roadside, forecourt, drive, car park: every bit of that is ground our technicians serve, and none of that requires your vehicle to travel to us. ## Littledean Hill: stranded wherever you stopped Not everybody has the opportunity to pull in anywhere suitable. Set off, then noticed? Landed on the verge beside Severn View, or sat in some lay-by with your hazards going? That is a common call here. Not an odd one. Sit beside your car when it is sensible to sit in it, but clear of it when it isn't. Every mile a diesel obliges you for on petrol draws the blend further into your fuel system — and oblige it often will, which is why the engine does not get restarted to limp somewhere better. However awkward the location, it is no bother for us to come to it, and that's much better for your car than pressing on. Three answers decide most of the work: what went in, about how much, and whether your engine has run since. We ask for those answers when we get to the car in the car park by The Fern Ticket. Then the tainted blend comes out of that tank, the fuel lines are flushed, and where your Peugeot 308 has a replaceable filter, it comes off. When new diesel is in and the system bled, our technicians fire it up and check it runs properly before you set off. ## A few miles on petrol in a diesel: what now? Here is where your M50 comes in — under 10 miles away from Littledean Hill. Some distance along, and onto it in the first place: a wrongly fuelled diesel will frequently manage both before anything feels wrong. What you get then is seldom a clean stop. Power ebbs away, your idle goes uneven, and there may be some smoke. The next safe exit is the one to take. Switch off there, and leave the restarting alone. Assume the worst of that on a long run. Anything approaching the under 15 miles to the nearest city, and the mixture has been through the fuel filter, through the pump, through the fuel injectors. Say so when you ring. What our engineers bring changes. ## About Littledean Hill Littledean Hill is a suburban area in Gloucestershire, situated inland at an elevation of 244 metres, with semi-detached housing being the predominant type of accommodation. Littledean Hill lies approximately 10.7 miles from Gloucester and 103.5 miles from London, placing it in a relatively rural setting. Littledean Hill is close to nearby places such as Collafield, Double View, and Cinderford, and has a population of around 3635 residents. Littledean Hill's location allows for easy access to surrounding areas while maintaining a sense of community, ## What comes next when our engineers get to you in Littledean Hill - Our technicians ask first, quote after. What was put in? How much? Has the engine run? Those replies change what the work really is. - The tainted fuel is pulled out of your tank. - Lines rinsed, filter cleared. Whatever remains after that isn't the thing that created the issue. - The fuel system gets bled, on clean diesel. - Once it is turned on, our engineers make sure it runs correctly on new diesel. That has it ready to drive away. Lasting damage is very uncommon when it has been spotted quickly, and because everything is done where your car is, it never needs to go to a workshop. About as well as this goes, once the motor has turned: away from the pumps, receipt read, and your diesel Vauxhall Astra left close to Sheltered Housing Scheme 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, and so the fuel filter and the pump have had diluted fuel through them — hence cleaning the fuel lines rather than only draining the tank. ## AdBlue in your diesel tank instead, in Littledean Hill? AdBlue instead of petrol? Then the opening rule is unchanged — the engine remains off — whereas this issue underneath it's a separate one altogether. Petrol does two things to diesel: dilutes it, and strips out the protection the fuel system relies on. Corrosion and deposits are what a diesel tank ends up with instead, as AdBlue is urea dissolved in water. Usually the more serious of the two, AdBlue — and the detail lives on its own Littledean Hill page. Both are ours to handle. The smaller petrol nozzle fits a modern diesel filler neck with practically no resistance at all, which makes this mechanical instead of slapdash. Unfamiliar locations see most of it for that reason. So: filled up close to St Stephen's Church without thinking, in a diesel Kia Sportage you have had for two days? Call us where you are. Hire and courtesy cars tend to get driven further before anyone notices, and miles settles how much petrol gets to your injectors. ## Budgeting for a petrol-in-diesel fuel drain around Littledean Hill Our technicians can't put one number on this page truthfully, since this job is not one job. What shifts it: - Has it been started or driven? Nothing else counts for as much. - How much of the wrong fuel was put in, judged against how much the tank can hold. - Whether it was unleaded or AdBlue. - Whether a van can safely get to your car and work on it, which depends on where the car is. A clear answer rather than a range is what you get for telling us three things: your vehicle, the quantity, and if it has run. If it's not urgent — your car is at home and going nowhere — works too. It got a couple of streets and stopped. The throttle went dead, your idle turned lumpy, and the diesel Volvo XC60 is now waiting by Cinderford Library. That softness is the fuel failing to build pressure correctly not the motor packing up — and because there is no dashboard light for it, motors in that position generally get driven again before anyone phones. Don't. Turn it off then call us. ## Petrol in diesel: everyday queries around Littledean Hill ## At a petrol station in Littledean Hill, can you do a fuel drain there? A large part of this work gets done there, so yes. Routinely, provided the site agrees: Shire Fuels, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether we can work in that location is something our engineers answer on the spot. ## A couple of litres of petrol in a diesel — too much? Litres are not the measure. Proportion is, and much more than either, it counts whether anything has been run. Five litres in a nearly empty tank is a separate matter from five in a full one — but either way, the thing that decides how much work is needed is whether that blend has been pulled through the system. ## Already driven it with petrol in the diesel? What now? Somewhere safe, then stop, then switch off and leave it off. It's fixable much more commonly than motorists assume, even though driving is what takes the problem from the tank into your pump and injectors — and the single most valuable thing you can do now is not restart it. ## Will a fuel drain void my warranty? No. Carried out properly, clearing and cleaning is no modification at all, and the warranty from your manufacturer is untouched by it. What is likelier to start an argument is a diesel that has been run on petrol. One more good reason for your engine to remain off. ## Can I just add two-stroke oil and drive home? No. It belongs to a distinct problem from a separate era, and petrol has weakened something no oil of that kind puts back. Petrol stays in that tank afterwards, whatever else goes in, and your pump gets no break from it. ## Do I need a main dealer for petrol in a diesel? Wherever the vehicle is, our engineers drain and flush it there, so a drive to the main dealer doesn't come into it. ## You, and your vehicle, still together? Shut off is how the car remains. Turn it off somewhere sensible and leave it off, if you have already driven it. Cold, parked, going nowhere: that is the best position to be in. Motorists fear this much more than they need to. At the roadside, on the forecourt or at home — call-out fuel draining in Littledean Hill and across Gloucestershire.
