Put Petrol in a Diesel Car in Back O Loch?
Don't fire up the engine. If the petrol is still in your tank and the motor has not yet run, a drain is almost always all it takes — and that's decided in the coming few minutes, not by how much went in. Petrol in Diesel drains and flushes wrong-fuelled cars where they stand, across Back O Loch and the rest of East Dunbartonshire, on the forecourt, at the roadside or on a drive. Our technicians shall show you what the next part will be. Phone — that comes ahead of anything else.
What to do first about petrol in a diesel
- Never start the car — and never believe it when it runs. That is the bit most people get wrong about petrol in a diesel specifically. A petrol engine filled with diesel typically just can't run, and so the motorist stops and the wear halts with them. A diesel fed petrol normally starts, ticks over and drives away quite happily for several miles. It isn't okay. It is wearing that fuel system whenever you drive.
- Leave the car's ignition off also. Diesel has two jobs: it combusts, and before it burns it lubricates that high-pressure pump and its injectors. Petrol does the first and not the second. Flicking the car's ignition on is usually all it takes to prime the system, which carries the petrol out of the tank and into exactly those parts.
- Don't weaken it. Diesel poured on top gets rid of nothing, and so all you get is more of what was already there, since percentage is not how a diesel fuel system accepts petrol. Super unleaded? Simply petrol. The octane makes no difference.
- A vehicle that has not shifted is the quickest one to sort out, and so stay where you are if you reasonably can. Pulled up on the verge on Craigmount Street? Hazards on, then leave it there. A tricky spot suits us better than a started engine.
- Keep your whereabouts prepared before you dial. A postcode that starts G66 3 and whatever is closest to you with a name on it is the difference between the van arriving and the van circling.
- Call 0333 366 0103. Anticipate three points — what got in, approximately how many litres, plus if the engine has been started. Your responses determine whatever happens next.
Do not run it home. The commute has already sent a real amount of petrol-thinned diesel through the high-pressure fuel pump of your Volkswagen Golf, and the journey back would more or less double it for no reason at all. Phone us from the platform if that's handier. Our engineers do not need you hovering over your car outside Lenzie while our technicians get it done, and we would much rather speak to you tonight than learn on Monday.
You will be urged to move it out of that gateway and deal with it later. Do not. On the zig-zags at the local primary school, a wrongly fuelled Audi A3 running on diesel is in the way, and that is all it is. Start it three more times being courteous and you have turned a tank into a fuel system: every start primes the lines, every prime pulls more petrol through your filter toward your pump. Let them complain. Phone.
Do not drive it home to buy yourself time. You already have it: nothing gets worse whilst the car sits, since a diesel Peugeot 208 parked outside Woodhead Park is doing none of what it did on the way there. Your pump has stopped turning.
Petrol in a diesel does its harm as a ratio, which is the reason we ask at all: the same few litres waiting in a nearly empty tank make a far stronger mixture than they would in a full one. And petrol is rated on how well it withstands igniting under pressure — the opposite of what a diesel needs — so a stronger blend rattles more, smokes more, goes flatter. None of which means you need an answer prepared. Nearly nobody knows how full the tank was in a motor picked up two days ago, and we work that out on site. Do phone the hire or company firm first, though: some agreements want them to sign off the work, and that is far quicker settled before than after. Then phone us about the Skoda Superb close to Ebenezer Hall.
Fixed and starting aren't the same thing, and the difference is the circuit: we flush it, and take your filter off where there is a serviceable one. Compare that with the certain suggestion you'll get — drain the car, refill with clean diesel. Only half right. Do exactly that to a diesel Citroen C4 close to St Columba's Parish Church and it will start, which is precisely why the tip sounds plausible. Then the engine draws the petrol left behind in the filter, and in the feed lines, straight back through your pump, as draining a tank does nothing whatever about fuel that has already left it. Phone us instead.
Forecourt draining for petrol in a diesel
A good portion of the job ends up done at a pump, as that is where it mostly starts. Still at Gulf? Then that's generally where it takes place. Garage forecourts are everyday for us, with the permission of the station.
At a garage, it is spotted with your motor never fired, and no place else does that. The few seconds between seeing the till receipt and reaching for the keys determine how much needs cleaning. Everywhere other than a forecourt — a car park, a drive, a lay-by — your car was fired up and driven to get there, so fuel was pulled from that tank, through your filter then into the high-pressure fuel pump. That means your lines and the filter require rinsing as well as your tank. It's not a calamity, and our technicians can still sort it out where the vehicle sits.
Clear of the pump, the next driver can get past — so yes, let the staff help you roll the vehicle. Worth doing. Four vehicle lengths isn't worth the risk.
Back O Loch and the towns near it
Woodilee, Townhead, Hillhead, Oxgang, Barleybank — all of these on the runs that carry us across to Back O Loch as well, a residential suburb.
Not on this list? That says nothing. The names above are just the closest few, and nearly all locations across East Dunbartonshire have a page of their own elsewhere on this site. Near the border, or somewhere your phone misreads? Contact us and enquire rather than guessing.
The ground this page covers appears on our map. We work roadside, on forecourts, on driveways and at car parks throughout all of it, and your vehicle doesn't need to come to us.
Back O Loch: stuck where you parked
A chance to stop anywhere suitable does not fall to everybody. A common call for us and not an odd one: worked out after setting off, ended up by the verge of Lithgow Avenue or at a lay-by with the hazards flashing.
Whether you sit beside your car or step clear of it rests on if staying in it looks safe. Do not restart the motor to nurse the vehicle somewhere better — a diesel running on petrol will often oblige, and every mile it obliges for is drawing the mix further into the system. Our van coming to a tricky location is no problem for us, and it is far better for the vehicle than carrying on.
Petrol in a diesel, and your car has travelled
Here is where the M80 comes in — under 3 miles away from Back O Loch. It will usually get you onto it, and some way along, before you feel a thing. Then it is some smoke, a rough idle and power falling away — not a clean stop. Misfuelled diesels seldom give you one of those.
Come off at the next sensible junction, switch off, and never start it to move it. Long run? Anything near the under 10 miles to the nearest city and you should presume the lot — filter, pump, injectors, all of it got to by the petrol. Say that on the phone, since it changes what goes in our van.

The job in Back O Loch, step by step
- Our engineers ask first, price after. What went in? How much? Has the engine run? Those responses alter what the work actually is.
- We drain that tank of all the tainted fuel.
- What is left in the system shouldn't be what started the trouble, and so the fuel lines get purged and the fuel filter cleared.
- Clean diesel goes in, and then the system gets primed.
- Our engineers fire it up and confirm it runs properly on fresh diesel.
After that it is ready to pull away. We do everything wherever your car has stopped, which means it never has to be taken to a garage, and when it has been spotted soon, it's very unusual for there to be lasting damage.
AdBlue in a diesel tank in Back O Loch is a distinct matter
Do not start it: that opening rule applies whether what got in was AdBlue or petrol. What changes is the issue itself. The lubrication a fuel system relies on gets taken away by petrol, which thins the diesel. Corrosion and residue are what a diesel tank gets instead, because AdBlue is urea dissolved in water.
Both are ours. There is a separate Back O Loch page for AdBlue removal, with the full story on it — including the reasons it frequently turns out to be the worse of the two.
How much is a petrol-in-diesel fuel drain around Back O Loch?
Frankly, no single number fits on a page like this. This job changes. Here is what varies it:
- Whether the motor has been started or driven. This is the key one.
- Wrong fuel in, against what the tank takes — that proportion.
- Which was put in: petrol or AdBlue.
- Where is it? And can a van reach it and work there safely?
A straight answer instead of a range is what you get for telling us three things: the vehicle, the quantity, and whether it has run. If it's not urgent — the vehicle is at home and going nowhere — works too.
Petrol in diesel queries from Back O Loch motorists
At a petrol station in Back O Loch, can you do a fuel drain there?
Yes — forecourts are where a good portion of this takes place. Permission from the site is the condition. Given that, a forecourt like Shell is somewhere we are frequently, along with the rest of them locally — so name yours on the phone and you will hear whether working there's possible.
How much petrol in a diesel is too much?
Whether your engine has run counts far more, though the ratio matters too, instead of the litres. 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 blend been pulled right through, or has it not?
Petrol in my diesel, and I have driven the vehicle
Switch off somewhere sensible, then keep it that way after you stop. Driving moves the issue along — out of that tank, into your pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one really helpful thing left to you isn't restarting the vehicle.
My warranty — does a fuel drain void it?
A drain and flush carried out properly is not a change and doesn't void a manufacturer's warranty. What's likelier to start a disagreement is a diesel that has been run on petrol. One more reason for the motor to stay off.
Could I put some two-stroke in and just drive?
What petrol has thinned isn't restored by two-stroke oil, which is an old fix for a separate fault. So no. Afterwards? Still petrol in your tank, and a pump that has to cope with the stuff.
Main dealers and petrol in a diesel
Wherever your car is, our technicians drain and clean it there, so a trip to the main dealer doesn't come into it.
Standing next to it?
Do not switch the engine on again.
If you have already driven it, stop somewhere safe, switch it off then keep it off. Cold and parked, a vehicle is in the best position available — and drivers fear this a lot more than the recovery rate warrants.
