Put Petrol in a Diesel Car in Wilton? Don't Start It
Petrol in Diesel drains and flushes misfuelled cars where they stand, on the forecourt, by the roadside or on a driveway, across Wilton and the rest of Scottish Borders. The very first thing to do is not to fire up the engine. When the engine has not been started and the petrol is still in the tank, a tank drain is nearly always all it needs, and the next few minutes decide that, not how much was put in. Contact us before everything else happens, and you will hear what happens from there.
Petrol in a diesel: what to do now
- While you drive, your pump and the injectors suffer. That's why you don't crank it, and why you do not trust it once it has started. The thing about petrol in a diesel especially — the part motorists get wrong — is that it pulls away fine for the first mile or two. Diesel in a petrol motor normally won't run at all, which stops the driver and stops the wear with them. This one lets you keep going.
- Leave the ignition off also. Diesel does two tasks: it combusts, and before it combusts it protects the high-pressure pump and its injectors. Petrol handles the first and not the second. Switching the car's ignition on is commonly sufficient to prime your system, which draws that petrol out of your tank and into precisely those components.
- That advice supposes a diesel fuel system tolerates petrol by percentage. It will not. Tip diesel on top and nothing at all is taken out; what you end with is a bigger tank of the same mix. And no, the type makes no difference — super unleaded is still petrol.
- We would much rather drive to a tricky location than have it started — so if you safely can, stay put. Nothing is simpler to sort than a vehicle that has never moved. On the verge on Mayfield Drive, that means hazards on and keep the vehicle.
- Find out where you are before ringing. A postcode that starts TD9 7, and the name of whatever is closest to you. Otherwise the technician circles instead of showing up.
- Three replies settle the whole job: the stuff you poured in, the approximate amount of it, and whether it has been running since. Our number is 0333 366 0103.
How many miles you went is what we query, not how long the motor has been sitting — and here's why. Diesel performs two jobs on its way through an engine: it ignites, and before burning it lubricates its high-pressure fuel pump and its injectors. Petrol manages the first only. So a hurried refuel on the way in, the penny dropping somewhere around eleven, and a diesel Volkswagen Golf parked at the nearest station since quarter past eight tells us those few miles were driven with the pump labouring on a fuel robbed of a lot of its protection. Call us then leave the car just where it stands.
Someone will urge you to shift the car out of the gateway and fix it later. Please don't. A wrongly fuelled diesel BMW 3 Series on the zig-zags at the local primary school is an inconvenience; the same vehicle started three more times to be polite is a fuel system rather than a tank. Every restart primes your lines and pulls more petrol past your filter and into the pump. Stay put, let them moan, and phone us.
Chance the drive home from Station Bar? No. It will start and it will drive off quite happily, which is the trouble — a diesel on a diluted tank runs generally while wearing the parts the fuel should be protecting. Leave the Audi A4 and phone.
Off the forecourt, receipt read, a couple of hundred yards, parked close to Wilton Parish Church. For a diesel Vauxhall Astra whose engine has turned, that's about the best version there is. Phone us, and let the vehicle stand with the ignition alone. Short helps, genuinely — but a start is a start and a drive is a drive, and the fuel filter has had weakened fuel through it, and so has the pump. Which is why the fuel lines get flushed and not just that tank emptied.
By now the tank is the least of that. Run a diesel and the mix goes into your filter, into your lines, into your pump, into its rail — and none of that leaves with the tank contents. A diesel Ford Fiesta that made it near Wilton Mills Sign needs its system flushed. Clearing is not the same thing.
Can petrol be taken from a diesel on the forecourt?
Most of this job starts at a pump, so a good part of that ends up finished there. Still at Sainsbury's? Then that's generally where it happens. Garage forecourts are routine for us, with the permission of the owner.
Nowhere else except a garage can the mistake be halted with the motor still cold. The few seconds between reading your receipt and reaching for the key decide how much requires cleaning. Anywhere other than a forecourt — a car park, a private drive, a lay-by — your car was fired up and moved to get there, so fuel was drawn from that tank, through your filter then into the high-pressure fuel pump. That means the lines and your filter need flushing as well as your tank. It is not a calamity, and our technicians can still put it right where the car is.
Attendants will usually pitch in pushing it away from the pump, which lets the next driver get past. Accept the assistance. Firing it just to shift four car lengths isn't.
Service near Wilton
Hawick, Stirches, Silverbuthall, Cauld, Wilton Dean — all of these on our journeys that carry us out to Wilton itself, a residential suburb.
Our engineers still come. Those names above are merely the nearest neighbours, and a page is there for most places around Scottish Borders, so an absence from the list isn't an absence from the coverage. Guessing is the habit to skip, above all on a border or anywhere your satnav gets lost. Contact us to check.
See our map for the ground included on this page. All of it is ground our technicians cover: a kerbside, a forecourt, a driveway, a car park. You don't bring your car anywhere.
Wilton: stranded where you stopped
Not everybody gets a decent spot to pull in. A normal call for us and not an odd one: noticed after setting off, finished up on the verge on Stirches Road or at a lay-by with your hazards flashing.
Out of the vehicle if it's not sensible to wait in it, beside it if it is. Every mile a diesel obliges you for on petrol drags the blend further into your fuel system — and oblige it often will, which is why the engine doesn't get restarted to limp somewhere handier. However awkward the spot, it's no problem for us to come to it, and that's much better for the car than pressing on.
So you've run it? Petrol in a diesel over some miles
This is where your A74(M) comes into it — under 50 miles away from Wilton. It will often get you onto it, and some way along, before you spot a thing. Then it is smoke, a rough idle and power falling away — not a tidy stop. Misfilled diesels seldom give you one of those.
Take the next junction that's safe, pull up there, and never restart it to reposition. On a longer drive — anything near the under 50 miles to the closest city — assume the petrol has been through the fuel filter, your pump and your injectors, and say so when you phone. It affects what our engineers bring.

What our engineers do when we reach you around Wilton
- The responses change the work, which is why our technicians ask before giving a price: what got in, how much of it, and whether your engine has run.
- Out comes the tainted fuel.
- Lines purged, filter cleaned. Whatever remains later on is not the thing that caused the problem.
- Priming follows, once fresh diesel is in.
- Our engineers fire it up and check it runs correctly on new diesel.
At that point it's ready to set off. Lasting damage is very rare when it has been caught quickly, and because all of it is done where the vehicle is, it never has to go to a garage.
AdBlue in a diesel tank in Wilton is a different job
AdBlue rather than petrol? Then the first instruction is unchanged — your engine stays off — whereas this issue under it is a separate one altogether. Weakened diesel, and no protection left for the fuel system that depends on it. That's petrol. Rust and deposits are what a diesel tank ends up with instead, as AdBlue is urea dissolved in water.
Our technicians handle both, and AdBlue removal around Wilton has its own page with the details — including why it is often the more significant of the two.
How much is a petrol-in-diesel fuel drain around Wilton?
Our technicians can't put one number on this page frankly, as this job isn't one job. What shifts it:
- Has it been started or driven? Nothing else matters for as much.
- How much of the wrong fuel was put in, compared with how much that tank can hold.
- Whether it's unleaded or AdBlue.
- Where the car is, and whether a technician can sensibly get to and work on it.
Tell us your car, the quantity and whether it has run, and you will get a straight answer rather than a range. For the car at home that's going nowhere and isn't pressing, works too.
Things we get about petrol in diesel around Wilton
I am on a forecourt in Wilton. Can you drain the car on the spot?
Much of what our engineers do takes place nowhere else. So yes. Consent from the site is the condition. Given that, a forecourt like Morrisons is somewhere we're often enough, along with the rest of them locally — so name yours on the call and you'll hear whether working there is possible.
How much petrol is too much for a diesel?
Whether the motor has run matters a lot more, though the proportion matters too, rather than the litres. What settles how much work is required is if that mix 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 is the query.
Already driven it with petrol in your diesel? What now?
Somewhere safe, then stop, then turn off and keep it off. Not restarting it is the single most valuable thing available to you now. Driving does move the issue out of that tank and into your pump and injectors, yes, and it remains fixable far more frequently than people assume.
My warranty — does a fuel drain void it?
No. Carried out properly, draining and cleaning is no alteration at all, and the warranty from your manufacturer is untouched by it. What's likelier to start an argument is a diesel that has been run on petrol. One more good reason for the motor to stay off.
Could I put some two-stroke in and just drive?
No. Two-stroke oil is an old fix for a distinct issue and it doesn't replace what petrol has thinned. That tank still has petrol in it after that, and your pump still has to live with it.
Main dealers and petrol in a diesel
You do not need one. Your car is drained and cleaned wherever it is, with no need to bring it to a main dealer.
Is your car still with you?
Leave the car switched off.
Driven it already? Then somewhere sensible, stop, switch off, and no restarting it later. Cold, still, going nowhere: that is the best position to be in. Drivers fear this much more than they need to.
