--- title: Drain Petrol From a Diesel Car — Greatham canonical: https://www.petrolinadieselcar.co.uk/petrol-in-diesel/greatham-durham/ location: Greatham county: Durham latitude: 54.640750 longitude: -1.237400 service: Petrol in a Diesel Car updated: 2026-10-04 --- # Greatham: Put Petrol in a Diesel Car? With the tank still carrying the petrol and the engine not yet turned over, nearly every job takes only a drain, so leave the engine off. That outcome is determined in the minutes right after the fill-up, and not by the amount that was put in. Throughout Greatham and the remainder of Durham, Petrol in Diesel drains your car and cleans it where it is, whether at a roadside, on a drive or at a forecourt. One ring to us is enough: we shall explain what comes from here. Make that right away. ## Petrol in a diesel: what to do first - Do not start it — and do not trust it when it does start. Here is the bit most people get wrong about petrol in a diesel in particular. A petrol engine given diesel normally just will not run, and so the person stops and the damage stops with them. A diesel given petrol generally starts, ticks over and drives away quite happily for a few miles. It is not all right. It is eating into that fuel system while you drive. - Diesel burns, and before it burns it greases — the injection pump, those injectors. Petrol manages only the burning. So leave the ignition be as well: flicking it on is usually all it takes to prime that system, and priming pulls petrol from the tank into exactly those parts. - Topping up takes out nothing. It hands you a bigger tank of the same blend, since a diesel fuel system doesn't handle petrol by percentage the way that advice assumes — so do not add diesel on top to dilute it. Type is beside the point too: super unleaded is petrol. - Our team would rather travel to an odd place than have it started — so if you reasonably can, stay put. Nothing is easier to sort than a motor that has not shifted. On the verge on Mellanby Lane, that means hazards on and keep it. - A van showing up instead of circling hinges on two things: a postcode beginning TS25 2, and whatever is nearest to you with a label on it. Have both prepared before you dial. - What went in, approximately how much, and also if the motor has run — the three details decide your whole job. Phone 0333 366 0103 then tell us. ## Can petrol be taken from a diesel on a forecourt? Plenty of the work starts at a forecourt, which means a good part of it ends up done on site. Still at JET? Then that's typically where it takes place. Station forecourts are normal for us, with the consent of the site. A filling station is the one setting this can be halted before your engine has started. Everywhere else — a car park, a drive, a lay-by — the car was started and driven to get there, which means fuel was drawn from your tank, through the filter then into the high-pressure fuel pump. That's not a disaster, and our engineers can still sort it out where it sits. It does mean the fuel lines and the fuel filter need rinsing as well as that tank, and that is decided by the few seconds between reading your receipt and going for the key. Staff will usually chip in pushing it away from the petrol pump, which lets the next driver get past. Welcome the assistance. Shifting it four bays does not justify starting it. Straightforward, these ones, and the reason is the distance: a mile at gentle throttle pulls hardly any diesel. Petrol into a diesel Skoda Octavia somewhere around Greatham, a boot packed with shopping, and you sat at Heron Foods — call us. Exiting that space is not worth a restart. That tank gets emptied where it waits, your fuel lines rinsed, fresh diesel in, and you get home. ## Do our technicians reach your end of Greatham? Owton Manor, Graythorp, Newton Bewley, Cowpen Bewley, Brierton — every one of these on our trips that take us over to Greatham too, a coastal village. There are dedicated pages for most locations across Durham, and the ones listed above are merely the immediate neighbours — so yours being missing from this list says nothing about whether our technicians come. Contact us to check rather than assuming — boundaries particularly, and anywhere the satnav tends to get wrong. Look at the map for the ground shown here. Our technicians work roadside, on forecourts, on driveways and at car parks over all of that, and the vehicle does not need to come to us. Every restart primes the fuel lines and drags more petrol past your filter then into your pump. So a misfuelled diesel Peugeot 308 on the zig-zags by Greatham CofE Primary School is a hassle, whereas the same car fired up three more times to be helpful is a fuel system rather than a tank. A passer-by will urge you to shift it out of that gateway and deal with it later. Please don't. Leave it there, let everyone moan, then give us a call. ## Stuck on the kerb somewhere around Greatham? Not everyone finds a decent spot to pull over. Set off, then noticed? Finished up on the verge on Egerton Terrace, or sat in some lay-by with the hazards flashing? That is a routine call here. Not a rare one. Stay beside the motor when it's sensible to be inside, and out of it if it's not. Every mile a diesel obliges you for on petrol draws that mix further into your fuel system — and oblige it frequently will, which is why your engine doesn't get restarted to limp somewhere safer. We'll bring our van to a difficult place without any trouble, and for the vehicle that is far better than pressing on. ## Petrol in a diesel, and the vehicle has moved Here is where your A1(M) comes in, under 15 miles away from Greatham. A drop in power, an uneven idle, smoke: those are the signs when they appear, instead of a clean stop — and a misfuelled diesel will frequently get you onto it and some way along before anything seems wrong at all. Come off at the first sensible junction, turn off, and never start it to move it. Assume the worst of it on a long drive. Anything approaching the under 25 miles to the closest city, and the mixture has been through the filter, through the pump, through the fuel injectors. Tell us when you ring. What our technicians bring changes. The pump is not turning, so whatever the diesel Audi A4 did on the way to Greatham Sports Ground, none of it is happening now. Nothing is getting worse whilst it stands. Take your time over this — but never drive the car home to buy any. ## Greatham itself Greatham is a small coastal village in County Durham, situated near the mouth of the Tees estuary at an elevation of around 18 metres. Greatham lies approximately 16 miles east of Durham city and some 221 miles north of London, within a landscape of coastal plains and nearby industrial areas. Greatham has a mix of housing types, but terraced homes are particularly prevalent in the village. Greatham is close to other nearby settlements, including Owton Manor, Graythorp, and Newton Bewley. ## What we do when our technicians reach you in Greatham - We ask first, quote after. What was put in? How much? Has your motor run? Those replies change what the work really is. - Your tank gets emptied of it. - Our technicians purge your fuel lines and clean the fuel filter, and so what is remaining in the fuel system is not what created the trouble. - The fuel system gets bled, on clean diesel. - It's run with clean diesel in it, and our technicians confirm that it's running smoothly. At that point it is ready to pull away. There's no need for a garage at any stage, since the work is all done where your car is, and when it's caught quickly, permanent damage is very rare. Why we are firm about not driving on: the pump sits before the injectors, so whatever a worn-out pump sheds passes downstream with your fuel. Leave the Dacia Duster close to Greatham Community Centre and phone us. ## AdBlue in your diesel tank instead, around Greatham? AdBlue instead of petrol? Then the first instruction is unchanged — your engine stays off — whereas the issue underneath it's a distinct one altogether. Petrol does two things to diesel: dilutes it, and removes the lubrication your fuel system depends on. AdBlue is urea in water, and in a diesel tank it causes rust and deposits instead. Usually the more serious of the two, AdBlue — and the full story sits on its own Greatham page. Both are ours to deal with. Hire car or company car? Call them before you ring us — some agreements want the hire firm to sign off the work, and sorting that out first is a great deal faster than sorting it after that. Then call us about the Mercedes E-Class close to Saint John the Baptist, and do not worry that you cannot say how full your tank was. Almost nobody can, in a car they picked up two days ago, and our technicians work it out there. The reason we ask is that petrol in a diesel does its damage as a share: the same few litres in an almost empty tank is a far stronger mix than in a full one. Petrol is rated on how well it resists igniting under pressure, which is the opposite of what a diesel needs — so the stronger the mix, the more it knocks, smokes and goes flat. ## How much is a petrol-in-diesel fuel drain in Greatham? One number would not be fair here, since this is not one job. These are the things that move it: - Started? Driven? Either answer counts more than anything else on this list. - The tank's capacity, set against how much of the wrong fuel got into it. - The kind of liquid in the tank, petrol or AdBlue. - Access: the vehicle's position, and whether working on it there is sensible for a technician. Tell us your vehicle, the quantity and if it has run, and you will get a firm answer rather than a range. Not time-critical, with the car at home and going nowhere? Then is fine. ## Petrol in diesel: common questions in Greatham ## At a petrol station around Greatham, can you do a fuel drain there? Yes — forecourts are where a fair part of this takes place. Routinely, provided the site consents: Esso, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether our engineers can work in that location is something we answer straight away. ## A few litres of petrol in a diesel — too much? Litres aren't the measure. Proportion is, and much more than either, it counts whether anything has been run. What determines how much work is needed is whether that blend has been sucked through the fuel system — since although five litres in an almost empty tank is a different matter from five in a full one, either way that is the question. ## Already driven it with petrol in your diesel? Now what? Somewhere sensible, then stop, then turn off and leave it off. Driving is what shifts the issue from the tank into your pump and injectors — but it's salvageable far more regularly than people fear, and the single most useful thing you can do now isn't restart the vehicle. ## Will a fuel drain void my warranty? It is not an alteration, so a drain and flush carried out correctly does not void a manufacturer's warranty. Running a diesel on petrol is the thing likelier to cause an argument with one, which is another good reason to leave the vehicle turned off. ## Could I put some two-stroke in and just drive? What petrol has diluted is not replaced by two-stroke oil, which is an old workaround for a distinct issue. So no. The tank still has petrol in it after that, and your pump still has to put up with it. ## Main dealers and petrol in a diesel Not at all. Our engineers drain and clean your car wherever it is, so there's no need to bring it to a main dealer. ## Is your vehicle still with you? Shut off is the way the car stays. If you have already driven the vehicle, pull in somewhere sensible, turn it off and keep it off. A parked, cold motor is the best place to be in, and this is recoverable from much more commonly than drivers expect. Throughout Durham and in Greatham: on-site fuel draining, at home or on the forecourt or at the kerbside.
