--- title: Fuel Drain in Barrow upon Soar — Petrol in a Diesel Car canonical: https://www.petrolinadieselcar.co.uk/petrol-in-diesel/barrow-upon-soar-leicestershire/ location: Barrow upon Soar county: Leicestershire latitude: 52.752400 longitude: -1.148800 service: Petrol in a Diesel Car updated: 2026-10-02 --- # Petrol in a Diesel Car in Barrow upon Soar Petrol in Diesel drains and flushes wrongly fuelled vehicles where they stand, on the forecourt, at the roadside or on a driveway, all over Barrow upon Soar and the remainder of Leicestershire. The first thing to do is not to start the motor. While the engine has not yet been started and the petrol is still in your tank, a drain is almost always all it needs, and the following few minutes settle that, not how much got in. Contact us before all else happens, so you will see what follows from there. ## What to do next about petrol in a diesel - Never start it — and never rely on it when it does start. That is the thing most people have wrong about petrol in a diesel in particular. A petrol engine fed diesel normally just cannot run, and so the person stops and the damage ends with them. A diesel given petrol typically starts, idles and drives off quite happily for several miles. It isn't okay. It is wearing out your fuel system while you drive. - Turning your ignition on frequently primes your system, and priming is what draws petrol out of your tank then into your pump and injectors. Those are the components diesel keeps lubricated on its way through, before it ignites. Petrol handles the burning and none of the lubricating. Leave your ignition be. - Don't add diesel on top to dilute it. A diesel fuel system doesn't accept petrol by percentage in the way that guidance presumes, and topping up takes out nothing — it merely hands you a larger tank of the same mix. The type makes no difference either: super unleaded is simply petrol. - Sit tight if it is wise to. Hazards on, motor off, leave the car. Wherever you have stopped — the verge on Cotes Road, anywhere — a tricky place for us is better than a started motor, and nothing is easier for us to handle than a vehicle that never shifted. - The van showing up rather than circling hinges on two things: a postcode starting LE12 8, and whatever is nearest to you with a sign on it. Have both ready before you ring. - Dial 0333 366 0103. Let us know what was put in, approximately how many litres, plus whether your car has fired. Those three answers determine your whole visit. Do not take it home. The commute has already put a real load of petrol-thinned diesel through the high-pressure pump of that Volkswagen Golf, and the journey back would more or less double it for no purpose at all. Ring us from the platform if that is handier. Our engineers do not need you standing over the vehicle at the nearest station while our engineers work, and we'd very much rather speak to you tonight than realise on Monday. ## Clearing petrol from a diesel at the forecourt Pumps are where the work mostly kicks off, and where a large part of it finishes. The drain normally takes place right there. Still on the forecourt at Pillings Lock Marina? Given the owner's agreement, that's somewhere our technicians work, and often. No place except a garage can it be halted with the motor still unstarted. Fuel drawn out of that tank and through your filter, all the way to the high-pressure fuel pump, is what happens when the engine is switched on and the vehicle is driven to where it is now: the car park, the private drive or the lay-by, everywhere other than the forecourt. So the flush covers your filter and the fuel lines along with that tank. That's still not a catastrophe, and our technicians deal with it where the car sits. What decides it is whether the ignition was turned in the seconds after the receipt was checked. Staff will generally help out pushing it out from the pump, which lets the next customer get by. Take the offer. Starting the car just to shift four car lengths isn't. Diesel Renault Megane. A few litres of unleaded. Done a couple of miles. Turned off now, outside Co-op Food. That is the phone call we hope for, because the question under it is about quantity through the pump not hours on the clock. ## Coverage around Barrow upon Soar The same journeys bring us to Quorndon, Walton on the Wolds, Mountsorrel, Woodthorpe and Cotes besides Barrow upon Soar, which is a village. Not on the list? It means nothing. The places above are only the nearest few, and most towns around Leicestershire have a page of their own elsewhere on this site. Near the border, or somewhere your satnav misreads? Call us and enquire instead of guessing. The ground this page includes is on this map. The lot is ground our technicians work: a kerbside, a forecourt, a driveway, a car park. You don't move the vehicle anywhere. Shift it out of that gateway and fix it later — that is what a passer-by will say, and it's wrong. Sitting on the zig-zags at Barrow Hall Orchard Church of England Primary School, a misfuelled diesel Nissan Qashqai is a hassle and nothing worse. Fired up three more times for politeness, it is no longer a tank problem but a fuel system one, as priming occurs with every start and more petrol goes through your filter towards the pump. Let them grumble. Phone us. ## Barrow upon Soar: stuck wherever you parked A chance to stop anywhere suitable does not come to everyone. Set off, then realised? Finished up along the verge of High Street, or sat in some lay-by with the hazard lights flashing? That's a routine call here. Not a rare one. Wait with the motor when it is sensible to be in it, yet out of the vehicle when it's not. It will usually oblige. A diesel running on petrol limps along perfectly willingly, and that is the trouble: restart the vehicle to reach somewhere handier and the blend goes further into the system with every mile covered. However awkward the location, it is no bother for us to get to it, and that is far better for your car than driving on. ## Some miles on petrol in a diesel: what next? This is where the M1 comes into it — under 10 miles from Barrow upon Soar. It will often take you onto it, and some way along, before you feel a thing. Then it's some smoke, a lumpy idle and power falling away — not a tidy stop. Misfuelled diesels rarely give you one of those. Take the first junction that is sensible, stop there, and don't restart the vehicle to reposition. Presume the worst of that on a long drive. Anything near the under 10 miles to the nearest city, and the contamination has been through the filter, through your pump, through your injectors. Say so when you ring. What we bring changes. ## Where's Barrow upon Soar? Barrow upon Soar is a village situated on the River Soar in Leicestershire, with a population of around 2400 people. Barrow upon Soar has a mix of old and new housing, but is predominantly characterised by detached homes. Barrow upon Soar is located near several other villages, including Quorndon, Walton on the Wolds, and Mountsorrel, and is about 8 miles south of Leicester. Barrow upon Soar sits at an elevation of 61 metres above sea level, in a riverside setting that has influenced its development over time. ## What follows when our technicians get to you in Barrow upon Soar - Three things get asked before any price — the fuel that got in, the amount, and if anything has been run since. Each answer shapes the work. - Your tank is cleared completely. - Lines purged, filter cleaned. Whatever is left later isn't the thing that created the problem. - Priming follows, once new diesel is in. - Our technicians fire it up and confirm it runs smoothly on new diesel. That leaves it ready to set off. Our engineers do all of this wherever the vehicle has come to a stop, which means it never needs to go to a workshop, and if it has been noticed early, it is very uncommon for there to be permanent damage. Rarely the problem, the place. On-street is the most common location our engineers work, and a narrow parking space is far preferable to a motor that has been driven somewhere more convenient. What does help, when you ring from near Holy Trinity, is three things: the side the filler is on, whether a van can stand next to without blocking the road, and if anything has run since you filled up. Then the Dacia Duster gets drained, the filter changed where a usable one exists, the fuel lines flushed and clean fuel put through the full circuit — as by now the worst of that is in the lines, not the tank. ## AdBlue in the diesel tank instead, in Barrow upon Soar? AdBlue rather than petrol? Then the first step is unchanged — the motor stays off — whereas the fault under it's a different one altogether. Diluted diesel, and no protection left for the system that depends on it. That is petrol. AdBlue is urea in water, and in a diesel tank it brings rust and residue instead. Usually the more serious of the two, AdBlue — and the detail sits on its own Barrow upon Soar page. Both are ours to handle. ## How much is a petrol-in-diesel drain in Barrow upon Soar? One figure would not be honest here, as this isn't one job. These are the things that shift it: - Has it been started or driven? Nothing else counts for as much. - How much of the wrong fuel went in, compared with how much that tank holds. - AdBlue or petrol, whichever was put in. - Where your car is, and if a technician can safely reach and work on it. Tell us what the vehicle is, how much went in, and whether the motor has run. A straight answer comes back, not a range. If it's not pressing — the car is at home and going nowhere — is fine too. No warning exists for this, which is why motors in that position typically get driven once more before anybody phones. Don't be one of them. The throttle went soft and the idle turned ragged after a couple of streets, and the diesel Mercedes A-Class is now waiting by Barrow upon Soar Library. Sluggishness there means fuel that can't build pressure correctly instead of a motor packing up. Turn off. Phone us. ## Petrol in diesel: everyday queries in Barrow upon Soar ## I'm on a forecourt around Barrow upon Soar. Can you drain it here? A good part of this work happens there, so yes. Agreement from the site is the condition. Given that, a forecourt like BP is somewhere we are regularly, 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 safe amount of petrol in a diesel? Proportion decides it rather than litres — and more than either, whether the motor has run. What determines how much work is required is if that mix has been pulled through your fuel system — because although five litres in an almost empty tank is a separate situation from five in a full one, either way that's the query. ## Already driven it with petrol in your diesel? What then? Switch off somewhere safe, then keep it that way after you stop. Driving shifts the issue along — out of your tank, into your pump and injectors. Motorists fear it a good deal more than the recovery rate warrants, mind. The one genuinely helpful thing left to you isn't restarting the car. ## My warranty — does a fuel drain void it? No. Carried out correctly, emptying and cleaning is no modification at all, and the warranty from your manufacturer is unaffected by it. A dispute over a warranty is likelier to come from running a diesel on petrol — so leave it switched off. ## Can I just add two-stroke oil and drive home? What petrol has thinned is not restored by two-stroke oil, which is an old remedy for a separate problem. So no. Petrol stays in that tank after that, whatever else goes in, and your pump gets no respite from it. ## Do I need a main dealer for petrol in a diesel? No. Our engineers drain and clean the vehicle wherever it is, so there is no need to take it to a main dealer. ## Still with the vehicle? Switched off is the way the car remains. Turn it off somewhere sensible then keep it off, if you have already driven it. Cold, still, going nowhere: that's the best place to be in. Drivers fear this much more than they need to. Call-out fuel draining around Barrow upon Soar and across Leicestershire — at the roadside, on the forecourt or at home.
