--- title: Fuel Drain in Craigie — Petrol in a Diesel Car canonical: https://www.petrolinadieselcar.co.uk/petrol-in-diesel/craigie-dundee-city/ location: Craigie county: Dundee City latitude: 56.477740 longitude: -2.930670 service: Petrol in a Diesel Car updated: 2026-10-02 --- # Put Petrol in a Diesel Car in Craigie? Don't Start It With the tank still holding the fuel and the engine not yet started, almost every job requires only a drain, so keep your engine off. That result is settled in the minutes immediately after the fill-up, and not by the amount that got in. Across Craigie and the rest of Dundee City, Petrol in Diesel drains the vehicle and flushes it where it stands, whether at a roadside, on a drive or at a forecourt. Just one call our way will be plenty: our engineers will tell you what follows next. Try it first. ## What to try next about petrol in a diesel - Don't start the vehicle. Started all the same? Then don't believe it. Diesel in a petrol car typically won't run, and so the driver stops and the wear stops with them. Petrol in a diesel? It starts. It idles. It pulls away normally, for several miles. Drivers get that reversed. It isn't all right — your fuel system is wearing down every mile you cover. - Two jobs, diesel: it combusts, and on the way through it keeps your high-pressure fuel pump and injectors greased. Petrol only does the one. That is why the car's ignition is left off too — switch it on and you usually prime your system, and that is petrol exiting the tank for precisely those parts. - Topping up removes nothing. It leaves you a bigger tank of the same blend, because a diesel fuel system doesn't accept petrol by percentage the way that advice suggests — so don't put diesel on top to thin it. Grade is beside the point too: super unleaded is petrol. - Stay where you are if you reasonably can. A vehicle that has not moved is the easiest one to deal with, and our team would rather drive to an awkward place than have it started. If you are stopped on the verge on Longtown Road, switch those hazards on and keep the vehicle there. - The van showing up rather than circling rests on two things: a postcode starting DD4 8, and whatever is next to you with a name on it. Keep both prepared before you ring. - Three replies settle the entire visit: the fuel you poured in, the ballpark volume involved, and whether anything has been running since. Our line is 0333 366 0103. ## Can petrol be pumped from a diesel at a forecourt? It begins at a pump, typically. Quite often the work wraps up at one as well. Still at Asda? Then that is typically where it gets done. Petrol station forecourts are routine for us, with the permission of the station. At a forecourt, the mistake is stopped with the motor never run, and nowhere else does that. The few seconds between checking the till receipt and going for the keys decide how much needs flushing. Anywhere other than a forecourt — a car park, a driveway, a lay-by — the car was switched on and moved to get there, so fuel was drawn from that tank, through the fuel filter and into the high-pressure fuel pump. That means the lines and the fuel filter require cleaning as well as the tank. It's not a disaster, and our engineers can still deal with it where the vehicle is. The attendants will usually offer to roll the car away from the petrol pump so the next driver can get past. That's worth doing. Starting it just for four car lengths? Don't. The call our engineers like sounds like this: diesel Volkswagen Passat, some litres of unleaded, run a couple of miles, now turned off at Lidl. What we're truly asking is how much fuel your pump has drawn — not how long ago it was. ## Craigie and the towns beside it As a residential suburb, Craigie gets a frequent visit, and the areas round about come along on the same round: Linlathen and Stannergate, Maryfield and Fintry, Douglas and Angus. Not on this list? It says nothing. The places above are only the closest few, and the majority of places in Dundee City have a page of their own elsewhere on the site. Phone to enquire rather than presuming — county lines above all, and wherever your satnav tends to struggle with. This map outlines the area the page covers. The vehicle never needs to come to us. We operate across all of that — roadside, forecourts, driveways, car parks. Nothing warns you, since from the driver's seat there's nothing to be warned about. Your diesel Ford Focus will have seemed completely ordinary on the way back from the local primary school, and they all do — which is the catch with petrol in a diesel instead of the reverse. Diesel in a petrol vehicle usually refuses to run, stopping the motorist and stopping the damage with them. Petrol in a diesel fires up, idles, drives off as though nothing had happened, and all the while your pump does its work without the lubrication its fuel is supposed to supply. Tell us approximately how far, and how hard. The harder counts more. ## Craigie: broken down wherever you pulled up Not everybody gets a decent spot to pull over. Hazards flashing in a lay-by somewhere, or stopped on the verge of Bellisle Place as you noticed after setting off — our engineers take that call regularly enough that it's the ordinary kind. Wait with the vehicle while it is safe to be inside, but clear of it when it's not. Do not start it up to get to a better spot. It'll go — a diesel on petrol normally obliges — and each mile of obliging drags the mixture deeper into the fuel system. We'll bring our van to a tricky location without any fuss, and for the vehicle that's far better than pressing on. The components that should be getting oiled are wearing instead, and the motor gives no sign of that: a diesel on a thinned tank starts and drives off just fine. Chance the drive home from The Boars Rock? Don't. Phone us and leave the Dacia Duster where it stands. ## Petrol in a diesel, and your car has moved This is where your M90 comes in — under 25 miles from Craigie. Lost power, a lumpy idle, smoke: those are the symptoms when they come, instead of a clean stop — and a misfuelled diesel will frequently take you onto it and some distance along before anything feels wrong at all. Pull off at the next safe exit, switch off, and do not start it to reposition. Presume the worst of it on a long run. Anything approaching the under 3 miles to the closest city, and the contamination has been through the filter, through your pump, through your injectors. Tell us when you phone. What we bring alters. ## Where's Craigie? Craigie is a coastal suburban area in Dundee City, situated approximately 2.1 miles from Dundee city centre. Craigie sits at an elevation of 56 metres, overlooking the coastline. Craigie is characterised by its predominantly semi-detached housing stock, which reflects the area's residential development. Craigie is close to nearby places such as Linlathen, Stannergate, and Maryfield. ## When our engineers arrive with you around Craigie: what we do - Our engineers ask first, quote after. What went in? How much? Has your motor run? Those replies shape what the work actually is. - That tank gets drained completely. - Fuel lines are flushed through and your filter cleaned, leaving nothing in your system that caused any of this. - We put fresh diesel in and prime the system. - The engine is started and checked to be sure it runs correctly on new diesel. The vehicle is then ready for you to pull away. Everything is done where the vehicle is, so it never needs to be taken to a garage, and when it has been spotted soon, long-term damage is very uncommon. Ringing from near St Ninian's Scottish Episcopal Church? Three things help us. The filler — which side of the vehicle it's on. Room for our van next to you, without the road being blocked. And whether anything has run since the fill-up. The location itself scarcely matters: on-street is where we work most, and we would far rather have a tight spot than a car someone has driven somewhere simpler. Then it is a drain for the BMW 5 Series, a filter change where there's one worth changing, lines rinsed, fresh fuel put round the entire circuit. By now the worst of it is in the fuel lines and not your tank. ## A separate problem: AdBlue in a diesel tank in Craigie If what got in was AdBlue instead of petrol, the first rule is the same — don't fire it up — yet the issue is not. Petrol weakens your diesel and takes away the protection the fuel system relies on. AdBlue is urea dissolved in water, and in a diesel tank it causes corrosion and residue instead. Frequently the more significant of the two, AdBlue — and the details lives on its own Craigie page. Both are ours to handle. Most of these occur somewhere new, and the cause is mechanical rather than slapdash — practically no resistance meets a narrower petrol nozzle entering a current diesel filler neck. Two days into a diesel Vauxhall Astra, a fill-up near CWGC Cross of Sacrifice that you didn't think about? Call us from where you are. Courtesy and hire cars go further before anyone spots it, and the further they go, the more petrol ends up at the fuel injectors. ## What a petrol-in-diesel fuel drain costs around Craigie One figure would not be honest here, because this isn't one job. These are the things that shift it: - This is the big one: whether the engine has been run, or driven. - The tank's capacity, set against how much of the wrong fuel got into it. - The sort of liquid in the tank, petrol or AdBlue. - Where is it? And can a technician get to it and work there sensibly? Tell us the vehicle, the quantity and whether it has run, and you'll get a firm answer instead of a range. For your car at home that is going nowhere and isn't pressing, is fine too. ## Craigie drivers ask us these about petrol in diesel ## Can you do a fuel drain at a petrol station in Craigie? Yes, and it is where a big portion of this work happens. Routinely, provided the site agrees: Esso, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether we can work in that location is something our technicians answer there and then. ## How much petrol in a diesel is too much? Proportion settles it instead of litres — and more than either, whether the motor has run. Five litres into a nearly dry tank is not five into a full one, no. But both land on the same question in the end: has that mix been pulled right through, or has it not? ## Already driven it with petrol in the diesel? What then? Pull over somewhere sensible, switch off, then leave the vehicle off. Driving is what takes the issue from your tank into the pump and injectors — but it's salvageable a lot more commonly than people expect, and the single most valuable thing you can do now is not restart the vehicle. ## Is a fuel drain going to void my warranty? A manufacturer's warranty survives a drain then flush done to a proper standard, which is no modification at all. What's likelier to start a dispute is a diesel that has been run on petrol. One more reason for the engine to stay off. ## Adding two-stroke oil, then driving home What petrol has thinned isn't restored by two-stroke oil, which is an old remedy for a different fault. So no. The pump still has to put up with it, since your tank still has petrol in it afterwards. ## A main dealer for petrol in a diesel — needed? You do not need one. The car is drained and flushed wherever it is, with no need to bring it to a main dealer. ## You, and the car, still together? Shut off is the way the car stays. Driven it already? Then somewhere safe, stop, turn off, and no restarting the vehicle later. Cold, stationary, going nowhere: that's the best place to be in. Motorists fear this far more than they need to. Clearing misfuelled vehicles, Craigie and the rest of Dundee City, wherever they are. Roadside. Forecourt. Home.
