Put Petrol in a Diesel Car in Quarter?
Petrol in Diesel drains and cleans wrongly fuelled vehicles where they stand, on the forecourt, at the roadside or on a private drive, across Quarter and the rest of South Lanarkshire. The first thing to do is not to turn on your engine. While the motor has not yet run and the petrol is still inside your tank, a tank drain is almost always all it needs, and the coming few minutes determine that, not how much went in. Phone before anything else starts, and you will know what happens next.
What to do now about petrol in a diesel
- Feed a petrol motor diesel and it will typically refuse to run at all, so the person stops there and so does the harm. Feed a diesel petrol and the engine starts, it idles, it drives off — all right for a few miles. Drivers have that reversed, which is the part they get wrong about petrol in a diesel specifically. So never start the vehicle. And having started, never trust it: that fuel system is wearing down whenever you drive.
- Switching your ignition on often primes the system, and priming is what draws petrol out of the tank then into the pump and injectors. Those are the parts diesel keeps protected on its way through, before it ignites. Petrol handles the burning and none of the lubricating. Leave the ignition be.
- Topping up gets rid of nothing. It gives you a bigger tank of the same mixture, because a diesel fuel system will not handle petrol by percentage as that advice implies — so don't pour diesel on top to thin it. Octane is immaterial too: super unleaded is petrol.
- We'd rather drive to a difficult location than have it started — so if you reasonably can, stay still. Nothing is simpler to handle than a motor that has never moved. On the verge on Darngaber Road, that means hazards on and keep the car.
- Have your location ready before you ring. A postcode beginning ML3 7 and whatever is next to you with a sign on it is the difference between a van arriving and the van circling.
- Dial 0333 366 0103. Anticipate three things — what was put in, about how much, plus if the motor has been turned over. Your answers determine whatever comes after.
Do not take it home. The journey in has already forced a real amount of petrol-thinned diesel through the high-pressure pump of your Volkswagen Tiguan, and the journey back would close to double it for no reason at all. Call us from the platform if that's quicker. Our engineers don't need you hovering over the vehicle at Chatelherault whilst our engineers get it done, and we'd much rather hear from you tonight than discover on Monday.
Each start primes that fuel system and draws more of that blend out of your tank and on to your pump — which is why a vehicle shuffled twice into a better spot has quietly become a harder job than one left exactly where it stopped. So where we can't work next to your diesel Ford Focus, our engineers move the vehicle without running it. None of that is fuss about a couple of seconds of running. Car parks like the one outside Co-op Food we work in regularly, and the fuel is seldom the difficult part: that bay is. Motors either side, a trolley shelter behind, occasionally a height barrier at the way in settling if a technician can reach you at all. Tell us how boxed in you are, and which way the car faces.
Normal on the way out, sluggish on the way back. If that's how the trip to Knowetop Wood went, your tank is the place to look. Petrol thins diesel, and thinner fuel leaks past the close-fitting parts that are supposed to build injection pressure — so the farther the Audi A3 went, the less well it held that pressure. Stop somewhere sensible, turn off and call us.
Unfamiliar locations are where this happens most, and the reason is mechanical rather than careless: the slimmer petrol nozzle slides into a modern diesel filler neck with practically no resistance at all. Filled up by Darngaber Castle, Motte without thinking, in a diesel Renault Captur you have had for two days? Phone us where you are. Hire and courtesy cars often get driven further before anyone spots it, and mileage is what settles how much petrol ends up at the injectors.
Put right and starting aren't the same thing, and the difference is your circuit: we flush it, and take the filter off where there's a working one. Compare that with the sure of themselves suggestion you'll get — drain the vehicle, refill with new diesel. Only half right. Do precisely that to a diesel Citroen C4 near Eddlewood Public Hall and it'll start, which is precisely why the tip sounds sensible. Then your engine sucks the petrol left behind in your filter, and in the feed lines, straight back through the pump, as draining a tank does nothing whatever about fuel that has already left it. Call us instead.
Can petrol be drained out of your diesel on the forecourt?
Pumps are where the work often starts, and where a fair portion of it finishes. If you are still at the forecourt at Esso, that is typically where this drain gets done — we operate on petrol station forecourts routinely, with the owner's permission.
Nowhere except the forecourt can it be stopped with the motor still cold. Everywhere else — a car park, a private drive, a lay-by — the vehicle was switched on and driven to get there, which means fuel was pulled from your tank, through your filter and into the high-pressure fuel pump. That's not a disaster, and we can still deal with it where it is. It does mean your lines and the filter need rinsing as well as that tank, and that's determined by the few seconds between checking the receipt and going for your key.
Clear of the petrol pump, the next driver can get by — so yes, let the staff help you push the car. Worth it. Shifting the car four lengths doesn't merit firing the motor.
Parts our team serve near Quarter
Being a village, Quarter has a steady visit, whilst its neighbours nearby go with it on that same journey: Limekilnburn and Eddlewood, Cadzow and Low Waters, Meikle Earnock.
If yours is not on this list it does not mean we do not come — there are dedicated pages for most locations across South Lanarkshire, and the ones named above are just the closest neighbours. Ring us and enquire instead of guessing — county lines particularly, and anywhere the satnav can get wrong.
That map shows the area the page covers. The vehicle doesn't need to come to us. We work throughout all of that — roadside, forecourts, driveways, car parks.
Stopped at the kerb somewhere in Quarter?
Some drivers get no suitable spot to stop at all. If you noticed after setting off and landed along the verge on Limekilnburn Road, or in a lay-by somewhere with the hazard lights on, that is a common call for us rather than an unusual one.
Whether you remain by the car or move away from it depends on whether being nearby looks sensible. It will frequently oblige. A diesel running on petrol limps along perfectly willingly, and that's the problem: fire it up to get to somewhere better and that blend goes further into the fuel system with every mile covered. Our van heading to an inconvenient location is no bother for us, and it's a lot better for your car than pressing on.
A couple of miles on petrol in a diesel: what now?
under 3 miles out of Quarter, your M74 is what counts here. A wrongly fuelled diesel will frequently take you onto it and some distance along before anything feels wrong, while the symptoms when they arrive are usually lost power, a rough idle and some smoke rather than a tidy stop.
Take the next junction that is safe, stop there, and never start the vehicle to move it. Presume the worst of it on a long drive. Anything approaching the under 15 miles to the nearest city, and the contamination has been through the fuel filter, through the pump, through the fuel injectors. Say so when you phone. What our technicians bring changes.
Where's Quarter?
Quarter is a village in South Lanarkshire, situated on the riverside at an elevation of 161 metres, with detached housing being the predominant type of accommodation. Quarter lies near the larger city of Glasgow, approximately 11.7 miles away, and is close to smaller settlements such as Limekilnburn and Eddlewood. Quarter has a population of around 715 residents and is located in a scenic area with nearby Cadzow. Quarter is positioned in a rural setting, yet is still within commuting distance to Glasgow.
What we do when our technicians get to you in Quarter
- Our technicians check what got in, how much, and whether your motor has run. The replies alter the work, which is why our technicians ask before pricing.
- Our engineers empty your tank of the contaminated fuel.
- What is left in your system should not be what started the trouble, and so your fuel lines get flushed and your filter cleaned.
- Clean diesel goes in, and then your system gets primed.
- It is fired up with clean diesel in it, and our technicians check that it is running smoothly.
After that it is ready to set off. There's no need for a workshop at any point, since the work is all done where the vehicle is, and when it is noticed soon, permanent damage is very unusual.
Quarter AdBlue removal is a distinct job
Never crank it: that first instruction stands whether what got in was AdBlue or petrol. What differs is this fault itself. Petrol does two things to diesel: weakens it, and strips out the protection the system depends on. AdBlue? Urea dissolved in water. Tip that in with your diesel and you get corrosion instead, plus residue.
We deal with both, and AdBlue removal in Quarter has its own page with the details — including why it's usually the more significant of the two.
Quarter prices for a petrol-in-diesel fuel drain
One price would not be fair here, as this is not one job. These are the things that move it:
- Started? Driven? Either answer matters more than anything else on this list.
- How much of the wrong fuel was put in, compared with how much your tank holds.
- Which was put in: unleaded or AdBlue.
- Where is it? And can a technician get to it and work there safely?
The vehicle, the amount, whether it has run — give us those and the answer comes back firm rather than as a range. Not urgent, with your car at home and going nowhere? Then works.
Quarter motorists ask us these about petrol in diesel
I am on a forecourt in Quarter. Can you drain it here?
A good share of this work takes place there, so yes. Our engineers attend Asda and the other forecourts around town regularly, with the station's permission — tell us which one you're at when you call and we will tell you whether our engineers can work there.
Is there a safe amount of petrol in a diesel?
Litres are not the yardstick. Ratio is, and far more than either, it counts whether anything has been run. A nearly empty tank with five litres in it, against a full one with the same five: distinct scenarios, definitely. Either way, the work needed comes down to one thing, which is if the fuel system has had that mix drawn through it.
Petrol in my diesel, and I have driven the vehicle
Stop safely. Off. Nothing after that. Driving is what shifts the issue from that tank into your pump and injectors — but it's recoverable far more commonly than motorists fear, and the single most useful thing you can do now is not restart it.
Will a fuel drain void my warranty?
No. Carried out correctly, emptying and flushing is no change at all, and the warranty from your manufacturer is untouched by it. A disagreement over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Could I put some two-stroke in and just drive?
No. It belongs to a different fault from a bygone era, and petrol has weakened something no oil of that kind replaces. The pump still has to live with it, as your tank still has petrol in it later on.
Do I need a main dealer for petrol in a diesel?
You do not need one. Your car is drained and flushed wherever it is, with no need to bring it to a main dealer.
Standing next to it?
The engine remains off.
Turn it off somewhere safe then leave it off, if you have already driven it. Cold and parked, a car is in the best place available — and drivers fear this much more than the recovery rate warrants.
