--- title: Drain Petrol From a Diesel Car — South Leith canonical: https://www.petrolinadieselcar.co.uk/petrol-in-diesel/south-leith-city-of-edinburgh/ location: South Leith county: City of Edinburgh latitude: 55.975830 longitude: -3.170150 service: Petrol in a Diesel Car updated: 2026-10-19 --- # Petrol in a Diesel Car in South Leith If you have not fired up your engine as yet, do not. A drain and nothing else is almost always what a car requires while the fuel is still sitting in that tank and your engine has not run, which is why it is the following few minutes that count, not how much went in. Petrol in Diesel comes to the vehicle wherever it has come to rest in South Leith or the remainder of City of Edinburgh, on the forecourt, at the roadside or on a driveway, and drains and cleans it there. Ring us before everything else happens, and you'll hear what comes from there. ## Petrol in a diesel: what to try now - Never fire it up. Fired up all the same? Then do not rely on it. Diesel in a petrol motor generally won't run, and so the driver stops and the harm ends with them. Petrol in a diesel? It starts. It idles. It drives off happily, for a few miles. People get that reversed. It's not okay — your fuel system is grinding every mile you drive. - Flicking the car's ignition on often primes the system, and priming is what carries petrol out of the tank and into the pump and injectors. Those are the components diesel keeps protected on its way through, before it burns. Petrol manages the burning and none of the lubricating. Leave your ignition be. - Do not thin it. Diesel added on top removes nothing, so all you have is more of what was already there, because percentage isn't how a diesel fuel system copes with petrol. Super unleaded? Just petrol. The type makes no difference. - A car that has never moved is the easiest one to handle, so wait where you are if you reasonably can. Pulled up on the verge on Broad Wynd? Hazards on, and leave the vehicle there. An awkward place works for us better than a started diesel. - Know where you are before ringing. A postcode that starts EH6 6, and the name of whatever is nearest to you. Otherwise our van circles instead of showing up. - Dial 0333 366 0103. Prepare for three queries — what got in, about how many litres, plus whether the motor has been started. The replies shape everything that follows. Nothing about the hours since has cost you anything. Fuel in a tank is inert, so a diesel Volkswagen Passat left outside Edinburgh Waverley this morning is no worse at five than it was at nine — what sucked weakened diesel through the pump was the drive in. Ring us before you set off to collect the vehicle. ## Can petrol be pumped from a diesel on a forecourt? Pumps are where the work mostly starts, and where a big chunk of that finishes. We work on station forecourts regularly, with the owner's consent, and so if you're still at the nearest petrol station that is generally where the drain takes place. Before the engine has run — the forecourt is the single place it ends up halted. Our technicians can still sort it out where it stands, even away from the forecourt. In a car park, on a driveway or in a lay-by, your car has been switched on and driven there, and that pulled fuel through the fuel filter then into the high-pressure fuel pump, all the way from that tank. None of that is a calamity, though the flush then has to go past that tank to the lines and your filter, and the few seconds between checking the receipt and going for the key are what settle that. Staff will generally help out pushing it clear of the pump, which lets the next driver get past. Accept the help. Cranking the car just for four car lengths? Not a chance. Straightforward, these ones, and the reason is the mileage: a mile at gentle throttle uses little of it. Petrol into a diesel Renault Clio somewhere in South Leith, a boot packed with shopping, and you stuck at Aldi — phone. Getting out of that spot is not worth another start. Your tank gets cleared where it sits, the fuel lines cleaned, clean diesel in, and you head home. ## Coverage in South Leith Leith, Hamilton Wynd, Woodbine Terrace, Thornville Terrace, Woodville Terrace — each of them on the rounds that bring us out to South Leith itself, a residential suburb. There are pages for the majority of locations around City of Edinburgh, and the ones listed above are simply the closest neighbours — so yours being left off this list tells you nothing about whether our engineers come. Phone and check instead of assuming — county lines above all, and anywhere a satnav might get wrong. Look at the map for the patch covered on this page. Roadside, forecourt, driveway, car park: the lot is territory our engineers cover, and none of that requires your car to move to us. Every restart primes your lines and draws more petrol through your filter then into the pump. So a misfilled diesel Skoda Octavia on the zig-zags outside the local primary school is a hassle, whereas the same motor restarted three more times to be helpful is a fuel system and not a tank. Somebody will advise you to move the car out of that gateway and fix it later. Please don't. Stay put, let people moan, and ring us. ## Roadside stops around South Leith Not everyone has a chance to pull in somewhere safe. If you worked it out after setting off and finished up on the verge beside Commercial Street, or in a lay-by somewhere with your hazards on, that's a normal call for us rather than a rare one. Out of the motor when it isn't safe to wait there, beside it if it is. It will frequently oblige. A diesel running on petrol limps along perfectly willingly, and that's the problem: fire it up to get to somewhere safer and the mixture goes further into the system with every mile covered. Our van driving to an awkward place is no problem for us, and it's a lot better for the vehicle than carrying on. Here is what a job in the car park by Malt & Hops typically looks like. Our engineers get to the car, ask what went in, approximately how much, and whether the engine has run since — these three answers determine much of the work. Then the contaminated mix comes out of the tank, the lines get rinsed, and the filter comes off where your BMW 3 Series has a replaceable one. New diesel goes in and the fuel system is primed. Then our technicians start the engine, make sure it runs smoothly, and you pull away. ## Petrol in a diesel, and the car has moved This is where the M8 matters, under 10 miles from South Leith. Some distance along, and onto it in the first place: a wrongly fuelled diesel will often do both before anything seems wrong. What you get then is rarely a clean stop. Power drains away, your idle turns lumpy, and there may be smoke. Pull off at the first safe exit, switch off, and don't restart the car to reposition. It alters what our engineers bring, so tell us when you phone: on a longer run — anything approaching the under 3 miles to the closest city — assume the petrol has been through your filter, your pump and the injectors. ## Where is South Leith? South Leith is a coastal suburban area in the City of Edinburgh, situated near the shore of the Firth of Forth. South Leith sits at a low elevation of around 8 metres, close to the historic port of Leith and the city centre of Edinburgh. South Leith is characterized by its predominantly flat-type housing, which reflects the area's urban development. South Leith is also proximal to other nearby places, including Hamilton Wynd and Woodbine Terrace. ## What happens when our engineers get to you in South Leith - Our engineers establish what was put in, how much, and whether the motor has run. The replies change the work, which is why our technicians ask before giving a price. - We drain your tank of all the polluted fuel. - Fuel lines are flushed through and your filter cleared, leaving nothing in your system that caused any of this. - Fresh diesel goes in, and then the fuel system gets primed. - Our technicians turn it on and check it runs correctly on new diesel. That has your car ready to pull away. Permanent damage is very unusual when it has been noticed quickly, and because everything is done where the vehicle is, it never needs to go to a garage. About as well as this goes, once the engine has turned: away from the pumps, receipt read, and the diesel Peugeot 3008 left by Custom House Gallery barely two streets on. Call us, and leave the vehicle off. A short hop does really help. It was still a start and still a drive, though, so the filter and your pump have had weakened fuel through them — hence flushing the fuel lines instead of only clearing the tank. ## A distinct problem: AdBlue in a diesel tank in South Leith If what got in was AdBlue instead of petrol, the first step is unchanged — do not fire it up — yet this problem is not. Petrol does two things to diesel: dilutes it, and strips out the protection your fuel system depends on. AdBlue? Urea dissolved in water. Put that in with your diesel and you get corrosion instead, plus build-up. Our technicians cover both, and AdBlue removal around South Leith has its own page with the full story — including why it is often the more serious of the two. ## South Leith pricing for a petrol-in-diesel drain One price would not be honest here, because this isn't one job. These are the things that move it: - Whether your engine has been run or driven. This is the main one. - The tank's capacity, set against how much of the wrong fuel went into it. - The sort of liquid in the tank, unleaded or AdBlue. - Where the vehicle is, and if our van can safely get to and work on it. Tell us what your car is, how much got in, and whether the motor has run. A clear answer comes back, not a range. Vehicle at home, going nowhere, nothing urgent about it — is good for that. ## Petrol in diesel queries from South Leith drivers ## Fuel drains on a South Leith petrol station forecourt Yes — forecourts are where a fair share of this happens. Tell us which one you're at when you ring and we will tell you whether our technicians can work there. With the site's permission our technicians attend BP and the other forecourts around town routinely. ## Is there a sensible amount of petrol in a diesel? Ratio decides it instead of litres — and more than either, whether your motor has 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 if that blend has been sucked through your fuel system. ## Already driven it with petrol in your diesel? What then? Somewhere sensible, then stop, then turn off and keep it off. Driving is what moves the issue from your tank into your pump and injectors — but it's salvageable a lot more commonly than people assume, and the single most valuable thing you can do now is not restart it. ## Fuel drains and manufacturer warranties No. Carried out properly, clearing and purging is no modification at all, and the warranty from your manufacturer is untouched by it. What is likelier to start a dispute is a diesel that has been run on petrol. One more good reason for the motor to remain off. ## Can I just add two-stroke oil and drive home? No. Two-stroke oil is an old remedy for a distinct issue and it doesn't restore what petrol has weakened. Later? Still petrol in that tank, and a pump that has to live with the stuff. ## A main dealer for petrol in a diesel — essential? There is no need to take it to a franchised dealer, since our technicians drain and flush your car wherever it is. ## You, and the vehicle, still together? Switched off is the way it stays. Switch it off somewhere sensible then keep it off, if you have already driven it. This is recoverable from much more often than drivers assume, and a stationary, cold motor is the best position to be in. Call-out fuel draining in South Leith and throughout City of Edinburgh — at the kerbside, on the forecourt or at home.
