Petrol in Diesel drains and cleans misfuelled vehicles where they sit, on the forecourt, by the roadside or on a drive, all over Craigentinny and the rest of City of Edinburgh. The first thing to do is not to fire up the engine. While the motor has not been started and the petrol is still in that tank, a drain is nearly always all it needs, and the next few minutes decide that, not how much was put in. A single call to us is sufficient: we can explain what comes next. Try this first. ## What to try next about petrol in a diesel - Do not crank it. Turned on regardless? Then do not trust it. Diesel in a petrol vehicle generally will not run, so the driver stops and the damage ends with them. Petrol in a diesel? It starts. It ticks over. It drives off normally, for a few miles. Drivers get that confused. It isn't all right — your fuel system is wearing every mile you do. - Flicking the car's ignition on usually primes that system, and priming is what pulls petrol out of the tank then into your pump and injectors. Those are the parts diesel keeps greased on its way through, before it combusts. Petrol handles the burning and none of the oiling. Leave the ignition be. - Do not add diesel on top to weaken it. A diesel fuel system does not handle petrol by percentage in the way that guidance presumes, and topping up gets rid of nothing — it only gives you a larger tank of the same mixture. The type makes no difference either: super unleaded is just petrol. - Wait where you are if you reasonably can. A car that hasn't shifted is the simplest one to handle, and we'd rather get to an awkward place than have it started. If you're parked on the verge on Stapeley Avenue, turn the hazards on then keep it there. - Have your location prepared before you dial. A postcode starting EH7 6 and whatever is next to you with a label on it is the difference between a van arriving and a van circling. - What got in, about how many litres, and if your car has fired — the three answers shape the entire call-out. Phone 0333 366 0103 and tell us. The high-pressure pump spent that morning run labouring on a liquid that had given up a great deal of the protection it is made for. Diesel protects that pump, and your injectors with it, before any of the fuel burns; petrol does the burning and none of the oiling. So take a diesel Renault Megane, fuelled at quarter past eight, driven in to work, and left standing at Brunstane until you realise around eleven. Three hours of sitting have altered nothing about it. The few miles before that did a lot, which is why the question our technicians ask you is about miles not time. Ring us. Leave it right where it sits. ## Can petrol be drained from a diesel at the forecourt? It kicks off at a forecourt, typically. Regularly it ends at one as well. Still at Morrisons? Then that is typically where it happens. Garage forecourts are everyday for us, with the permission of the station. A filling station is the one spot it is caught before your motor has run. Fuel sucked out of that tank and through the filter, right to your high-pressure pump, is what happens when the engine is started and your car 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 your lines along with your tank. That is still not a catastrophe, and our technicians sort it out where your car is. What determines it is whether the key was reached for in the seconds after the till receipt was read. The attendants will normally happily roll the car clear of the pump so the next driver can get through. That is worth doing. Shifting it four lengths doesn't merit cranking it. The awkward part is that bay, not the fuel. Vehicles either side of you, a trolley shelter behind, and occasionally a height limit on the way in that determines if a van can reach you at all — so when you phone from a car park like the one at Lidl, say how much clearance there is about you and which way round the car is. Those our technicians cover regularly. Should there be no room to work alongside the diesel Volkswagen Tiguan, it gets moved with your engine off, and not out of fussiness over a few seconds of running: priming occurs at every start, more of the mixture exits the tank for your pump, and two shunts into a better space have quietly made a worse job of what was merely a motor sitting still. ## Parts we reach around Craigentinny As a residential suburb, Craigentinny sees a regular visit, and its neighbours round about go along on that same trip: Restalrig and Piershill, Northfield and Seafield, Meadowbank. There are dedicated pages for nearly all towns in City of Edinburgh, and the ones listed above are just the closest neighbours — so yours being missing from this list means nothing whatsoever about if our technicians come. Guessing is the thing to avoid, above all on a boundary or anywhere the satnav goes wrong. Phone and ask. That map is the ground the page includes. The car doesn't need to move to us. We work across the lot — kerbside, forecourts, driveways, car parks. ## Stranded by the kerbside around Craigentinny Some people get no safe spot to pull in at all. If you noticed after setting off and finished up on the verge on Craigentinny Avenue, or at a lay-by somewhere with the hazards going, that is a routine call for us and not an odd one. Whether you stay by the car or keep clear of it rests on whether being nearby seems wise. Don't restart the motor to nurse it somewhere better — a diesel running on petrol will usually oblige, and every mile it obliges for is drawing that mixture further into the fuel system. Carrying on does the vehicle far more harm than a technician driving out to an inconvenient spot, and that is no bother for us. Easy job, this one — until somebody drives it home. A diesel Peugeot 308 left at The Scottie Pub with petrol in the tank loses nothing by standing there overnight, so leave it and phone us once it is light. Expect a question about the trip there, though. Short and cold is precisely where petrol battles to burn, and what won't burn can get past the piston rings then into the oil. ## Some miles on petrol in a diesel: now what? This is where your M8 comes in, under 10 miles away from Craigentinny. A loss of power, a rough idle, smoke: those are the signs when they appear, instead of a clean stop — and a misfilled diesel will often get you onto it and some way along before anything seems wrong at all. Take the next exit that's safe, pull up there, and do not restart the vehicle to reposition. Suppose the worst of it on a long trip. Anything near the under 3 miles to the closest city, and the contamination has been through the filter, through the pump, through the fuel injectors. Mention it when you ring. What we bring changes. ## About Craigentinny Craigentinny is a coastal suburban area in the City of Edinburgh, situated approximately 2.1 miles from Edinburgh city centre. Craigentinny has a relatively low elevation of 17 metres and is characterised by predominantly flat-type housing. Craigentinny is close to nearby places such as Restalrig, Piershill, and Northfield, and is home to a population of around 3795 people. ## Once our engineers reach you around Craigentinny: what follows - Our technicians ask first, price after. What was put in? How much? Has your motor run? Those responses shape what the work actually is. - The polluted mixture is drawn from that tank. - Our technicians purge the lines and clear your filter, and so what's remaining in the system isn't what created the problem. - Fresh diesel goes in, and then the system gets primed. - The engine is turned on and checked to make sure it runs correctly on fresh diesel. After that it is ready to pull away. There is no need to go to a garage at any point, because the work is all done where the vehicle is, and when it's noticed soon, permanent damage is very rare. The pump rests before the injectors, and so whatever a worn-out one loses travels downstream with the fuel — which is why we are blunt about not driving on. Phone us, then leave your diesel Audi A3 where it's near RCCG King of Glory. ## Craigentinny AdBlue removal is a separate problem Never crank it: that first instruction holds whether what got in was AdBlue or petrol. What changes is this problem itself. The lubrication a fuel system depends on is taken away by petrol, which thins your diesel. Urea in water, AdBlue, and in a diesel tank that brings corrosion and build-up. Our technicians handle both, and AdBlue removal around Craigentinny has its own page with the full story — including why it is frequently the more serious of the two. Most of these happen somewhere unfamiliar, and the cause is mechanical instead of slapdash — practically no resistance meets a smaller petrol nozzle entering a newer diesel filler neck. Two days into a diesel Vauxhall Astra, a fill-up close to Wilson Memorial United Free Church that you did not think about? Call us from where you are. Courtesy and hire cars go further before anybody spots it, and the further they go, the more petrol ends up at your injectors. ## Craigentinny pricing for a petrol-in-diesel fuel drain Our technicians cannot put one price on this page frankly, because this job isn't one job. What shifts it: - Started? Driven? Either answer counts more than anything else on this list. - Wrong fuel in, against what that tank takes — that proportion. - Which was put in: petrol or AdBlue. - Where your vehicle is, and if our van can sensibly get to and work on it. A firm answer instead of a range is what you get for telling us three things: your car, the amount, and whether it has run. If it's not urgent — the vehicle is at home and going nowhere — works too. ## Petrol in diesel: frequent questions in Craigentinny ## Fuel drains on a Craigentinny petrol station forecourt Yes — forecourts are where a big share of this takes place. Permission from the site is the condition. Given that, a forecourt like JET is somewhere we're regularly, along with the rest of them locally — so name yours on the phone and you will hear if working there is possible. ## How much petrol in a diesel is too much? Ratio decides it rather than litres — and more than either, whether the motor has run. What determines how much work is needed is whether that mixture has been pulled through your fuel system — because even though five litres in a nearly empty tank is a separate matter from five in a full one, either way that's the query. ## I put petrol in my diesel and drove the car. What now? Stop safely. Off. Nothing after that. Driving moves the trouble along — out of your tank, into the pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one truly helpful thing left to you is not restarting the vehicle. ## Is a fuel drain going to void my warranty? A manufacturer's warranty outlasts a drain and flush done to a proper standard, which is no change at all. Running a diesel on petrol is the thing likelier to cause a dispute with one, which is another good reason to leave the car turned off. ## Adding two-stroke oil, then driving home No. Two-stroke oil is an old fix for a different problem and it doesn't put back what petrol has thinned. That tank still has petrol in it afterwards, and your pump still has to put up with it. ## Main dealers and petrol in a diesel Wherever the vehicle is, we drain and flush it there, so a drive to the main dealer doesn't come into it. ## Is the vehicle still with you? The engine remains off. Switch it off somewhere sensible then leave it off, if you have already driven it. This is recoverable from a lot more regularly than motorists fear, and a parked, cold vehicle is the best place to be in. Draining misfuelled vehicles, Craigentinny and the rest of City of Edinburgh, wherever they are. Kerbside. Forecourt. Home.
