Petrol in a Diesel Car in Wallyford
Petrol in Diesel drains and cleans misfuelled cars where they stand, on the forecourt, at the roadside or on a driveway, all over Wallyford and the rest of East Lothian. The very first thing to do is not to turn on the motor. While your engine has not yet run and the fuel is still sitting in that tank, a tank drain is nearly always all it takes, and the next few minutes determine that, not how much was put in. Our technicians shall explain what your next stage will be. Call us — it goes before anything else.
The first five minutes: petrol in a diesel
- Feed a petrol engine diesel and it will usually fail to run at all, and so the motorist stops there and so does the wear. Give a diesel petrol and the engine starts, it ticks over, it drives off — fine enough for several miles. Motorists have that backwards, which is the thing they get wrong about petrol in a diesel especially. So don't fire it up. And if started, don't trust it: that fuel system is wearing while you drive.
- Two tasks, diesel: it combusts, and on the way through it keeps your injection pump and injectors oiled. Petrol only handles the one. That is why the ignition is left off as well — flick it on and you often prime that system, and that's petrol leaving that tank for just those parts.
- Do not tip diesel on top to thin it. A diesel fuel system won't cope with petrol by percentage the way that advice suggests, and topping up clears nothing — it only leaves you a fuller tank of the same blend. The type makes no difference either: super unleaded is still petrol.
- Stay where you are if you reasonably can. A motor that has not shifted is the quickest one to deal with, and we'd much rather travel to a difficult spot than have it started. If you're pulled up on the verge on St Clements Crescent, turn the hazards on and keep the car there.
- Before you dial, gather your whereabouts. Anything closest to you with a sign on it, plus a postcode beginning EH21 8 — that's what settles whether the technician turns up or circles.
- What went in, about how many litres, and also if the engine has started — those three answers determine the entire job. Dial 0333 366 0103 and tell us.
Nothing about the hours since has lost you anything. Fuel sitting in a tank is inert, and so a diesel Volkswagen Passat left outside the nearest station this morning is no worse at five than it was at nine — what drew thinned diesel through your pump was the journey in. Call us before you set off to fetch it.
Our technicians will head your way, drain the tank, rinse your fuel lines then put fresh diesel in so you can drive home. So if petrol went into your diesel Nissan Qashqai in Wallyford and you're stranded outside Premier with a boot full of shopping, phone — and never fire it up once more to exit that space. A mile or so at gentle throttle uses little diesel, so those tend to be the straightforward ones.
Shift the vehicle out of the gateway and deal with it later — that is what a passer-by will say, and it is wrong. Sitting on the zig-zags by the local primary school, a wrongly fuelled diesel Mercedes C-Class is a nuisance and nothing worse. Fired up three more times for good manners, it is no longer a tank problem but a fuel system one, as priming happens with every start and more petrol goes through the fuel filter on to the pump. Let everyone complain. Give us a call.
Rattling, a lumpy idle, white smoke, a throttle gone soft. That's a misfilled diesel Kia Sportage telling you what's wrong. Turn off where you have stopped, near Wallyford Livingroom Church or anywhere else, and don't start the car to find a better place.
By this point the tank isn't where most of the trouble is. Once a diesel has run, that mixture is in your filter, the fuel lines, your pump and the rail — and it doesn't come back out with your tank contents. A diesel Skoda Superb that made it near Battle of Pinkie Cleugh Memorial Stone needs the system cleared, not emptied.
Draining petrol from the diesel at the forecourt
A large portion of this work gets done at a pump, as that's where it mostly kicks off. If you are still at the forecourt at Tesco, that's generally where this drain gets done — our technicians work on garage forecourts all the time, with the owner's agreement.
The forecourt is the only location it is stopped before your engine has fired. The few seconds between seeing the till receipt and reaching for your key decide how much needs rinsing. Everywhere other than the forecourt — a car park, a driveway, a lay-by — the car was started and driven to get there, so fuel was pulled from the tank, through your filter then into the high-pressure pump. That means the fuel lines and the filter need rinsing as well as the tank. It's not a calamity, and our technicians can still sort it out where the vehicle stands.
The attendants will generally happily move the car away from the pump so the next motorist can get through. That's worth doing. Four vehicle lengths isn't worth a start.
Service in Wallyford
Being a coastal village, Wallyford gets a regular visit, while the places round about go with it on that same journey: Pinkie Braes and Levenhall, Westpans and Pinkie, Lewisvale.
Not on this list? It tells you nothing. The places above are simply the nearest few, and nearly all locations around East Lothian have a page of their own elsewhere on the site. On the border, or somewhere your phone struggles with? Phone and enquire instead of guessing.
The patch the page spans sits on this map. Your car doesn't need to travel to us. Our technicians work throughout every bit of that — kerbside, forecourts, driveways, car parks.
Stuck by the kerbside somewhere around Wallyford?
The opportunity to pull in somewhere sensible doesn't come to everyone. Set off, then noticed? Finished up along the verge of St Clements Gardens North, or sat in some lay-by with your hazards going? That's a normal call here. Not an odd one.
Okay where you are? Remain with it. Not fine? Get out and away from it. Do not restart your motor to nurse the vehicle somewhere handier — a diesel running on petrol will frequently oblige, and every mile it obliges for is dragging the mix further into the fuel system. Driving on does the car far more harm than a technician coming out to an inconvenient place, and that's no trouble for us.
Some miles on petrol in a diesel: what now?
The M8 is the one which counts now, and lies under 15 miles from Wallyford. A loss of power, an uneven idle, smoke: those are the symptoms when they come, instead of a clean stop — and a misfilled diesel will frequently get you onto it and some way along before anything seems wrong at all.
The next sensible junction is the one to take. Switch off there, then leave the restarting alone. It changes what our technicians bring, and so say so when you ring: on a longer run — anything near the under 10 miles to the nearest city — assume the mixture has been through your filter, your pump and the injectors.
A bit about Wallyford
Wallyford is a coastal village in East Lothian, situated near the Firth of Forth and approximately 6.8 miles east of Edinburgh.

The job in Wallyford, step by step
- We ask first, price after. What was put in? How much? Has the motor run? Those responses change what the work actually is.
- Your tank gets cleared of it.
- What is left in the fuel system shouldn't be what created the issue, and so the fuel lines get cleaned and your filter cleared.
- Priming follows, once fresh diesel is in.
- Our engineers start it and check it runs properly on new diesel.
After that it's ready to drive away. We do everything wherever the car has ended up, which means it never needs to go to a workshop, and if it has been spotted quickly, it's very rare for there to be long-term damage.
AdBlue in a diesel tank in Wallyford is a separate matter
The problem is not the same, though the first rule is — don't crank it — if what was put in was AdBlue instead of petrol. Weakened diesel, and no lubrication left for the fuel system that relies on it. That is petrol. Rust and deposits are what a diesel tank ends up with instead, because AdBlue is urea dissolved in water.
AdBlue removal in Wallyford has a page of its own with the full story on it, including why it's frequently the more significant of the two. Our engineers handle both.
What a petrol-in-diesel fuel drain costs in Wallyford
We can't put one figure on this page honestly, since the job is not one job. What moves it:
- Started? Driven? Either answer counts more than anything else on this list.
- How much of the wrong fuel went in, weighed against how much that tank can hold.
- Which went in: petrol or AdBlue.
- Access: the vehicle's position, and if working on it there's sensible for a technician.
Tell us the car, the quantity and if it has run, and you'll get a clear answer instead of a range. Not urgent, with the car at home and going nowhere? Then does this job.
Petrol in diesel: frequent queries around Wallyford
Can you do a fuel drain at a petrol station in Wallyford?
Yes, and it is where a good share of this work gets done. Tell us which one you're at when you call and we will tell you if our engineers can work there. With the owner's permission we attend Thames and the other forecourts around town regularly.
How much petrol in a diesel is too much?
Ratio decides it rather than litres — and more than either, whether your motor has run. A nearly empty tank with five litres in it, against a full one with the same five: separate situations, definitely. Either way, the work needed comes down to one thing, which is whether the fuel system has had that mixture drawn through it.
Petrol in my diesel, and I have driven the vehicle
Pull over somewhere safe, turn off, then leave the vehicle off. Driving moves 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 truly useful thing left to you is not restarting it.
My warranty — does a fuel drain void it?
A drain then flush carried out correctly is not a modification and doesn't invalidate a manufacturer's warranty. Running a diesel on petrol is the thing more likely to cause a dispute with one, which is another reason to leave the vehicle turned off.
Adding two-stroke oil, then driving home
No. It belongs to a different fault from a bygone era, and petrol has diluted something no oil of that kind replaces. Later? Still petrol in that tank, and a pump that has to live with the stuff.
Do I need a main dealer for petrol in a diesel?
You don't need one. The car is drained and flushed wherever it is, with no need to take it to a main dealer.
You, and the vehicle, still together?
Leave it turned off.
Already driven it? Then stop somewhere safe, turn off, and let the car remain that way. This is recoverable from far more frequently than motorists fear, and a parked, cold car is the best place to be in.
