Hurlford: Put Petrol in a Diesel Car?
With your tank still holding the fuel and the motor not yet turned over, nearly every job requires only a drain, so keep the motor off. That outcome is settled in the minutes right after the fill-up, and not by the amount that was put in. Across Hurlford and the rest of East Ayrshire, Petrol in Diesel drains your car and flushes it where it is, whether by a roadside, on a drive or at a forecourt. Contact us and we will explain what follows after that before you do anything else.
What to try now about petrol in a diesel
- Never crank it — and never depend on it when it does start. This is the part motorists have wrong about petrol in a diesel especially. A petrol engine fed diesel generally just won't run, so the motorist stops and the wear halts with them. A diesel fed petrol usually starts, idles and drives off without complaint for a couple of miles. It's not fine. It is wearing out your fuel system as you drive.
- Two jobs, diesel: it combusts, and on the way through it keeps that high-pressure fuel pump and injectors lubricated. Petrol only manages the one. That is why the ignition is left off too — turn it on and you usually prime that system, and that's petrol leaving your tank for just those components.
- Topping up removes nothing. It leaves you a bigger tank of the same mix, since a diesel fuel system doesn't handle petrol by percentage as that advice presumes — so do not add diesel on top to thin it. Type is immaterial too: super unleaded is petrol.
- We'd much rather come to a difficult place than have it started — so if you sensibly can, stay put. Nothing is quicker to handle than a vehicle that has never shifted. On the verge on Academy Street, that means hazards on then leave the vehicle.
- Check where you are before phoning. A postcode that starts KA1 5, and the name of whatever is next to you. Otherwise the van circles instead of arriving.
- What got in, approximately how much, and also whether the engine has fired — the three details decide the full call-out. Ring 0333 366 0103 and tell us.
The high-pressure fuel pump spent that morning drive running on a liquid that had lost a great deal of the protection it is made for. Diesel lubricates that pump, and the injectors with it, before any of the fuel combusts; petrol does the burning and none of the lubricating. So picture a diesel Audi A4, topped up at quarter past eight, driven in to work, and parked sitting outside Kilmarnock until you realise around eleven. Three hours of sitting have altered nothing about it. The couple of miles before that did a lot, which is why the question our engineers ask you is about mileage rather than time. Phone us. Leave it exactly where it stands.
Park it overnight. Ring us first thing. Nothing about a diesel Mercedes A-Class sitting in the car park by the pub in the village degrades while it sits, tank of petrol or not, and the job remains a simple one right up till the moment it gets taken home. The question our engineers come with is about that trip there: a cold engine over a short run is where petrol burns least well, and whatever fails to burn can work its way past the rings into the oil.
Here's the full process. Diesel needs enough body to seal the tight tolerances it goes through, and petrol takes that away. That's it. Which explains the ordinary Richardson Park Recreation Ground call — a diesel Citroen C3, out there without complaint and back down on power, rough at idle, possibly a bit of smoke. Injection systems work hydraulically as well as chemically, so the fuel has to hold pressure and not just burn; thinned, it escapes past those clearances instead of building, and delivery comes weaker, later, less even than the motor was engineered round. Not a failing engine, though. Fuel that has stopped behaving like diesel. Put that right and it stops.
Hardly ever the trouble, the place. On-street is the most common spot our engineers work, and a narrow parking space is far preferable to a car that has been driven somewhere more convenient. What does help, when you ring from close to Propeller, is three things: the side the filler is on, whether a van can pull up beside without blocking the road, and whether anything has run since you filled up. Then the Volkswagen Touran gets drained, the filter changed where a serviceable one exists, the lines cleaned and fresh fuel put through the entire circuit — because by now the worst of it is in the lines, not your tank.
Most of these happen somewhere strange, and the cause is mechanical instead of sloppy — practically no resistance meets a slimmer petrol nozzle entering a current diesel filler neck. Two days into a diesel Ford Fiesta, a fill-up close to War Memorial that you didn't think about? Call us from where you are. Courtesy and hire cars go further before anybody clocks it, and the further they go, the more petrol winds up at the injectors.
Draining petrol from your diesel on the forecourt
Much of the job starts at a forecourt, which means a big part of it is finished at one. The drain typically gets done there and then. Still on the forecourt at BP? Given the owner's consent, that is somewhere our engineers work, and regularly.
Before the engine has fired — the forecourt is the only location it ends up spotted. The few seconds between seeing your receipt and going for your key decide how much requires flushing. Anywhere other than the forecourt — a car park, a drive, a lay-by — the vehicle was fired up and moved to get there, so fuel was drawn from that tank, through your filter and into the high-pressure fuel pump. That means the fuel lines and the filter need cleaning as well as your tank. It's not a catastrophe, and our engineers can still put it right where the vehicle is.
Wheel the vehicle out of the way if the attendants suggest it, and they normally will. The next customer gets through the pump, and that's worth doing. Starting it just to roll four car lengths is not.
Hurlford plus the places beside it
As a village, Hurlford gets a steady visit, whilst the places nearby come along on that same round: Crookedholm and Bellfield, New Farm Loch and Kilmarnock, Riccarton.
We still come. The places above are only the immediate neighbours, and a page is there for most towns across East Ayrshire, and so an absence from the list isn't an absence from our coverage. Phone and ask rather than assuming — county lines especially, and wherever a satnav may misread.
The map is the ground this page covers. The vehicle does not need to travel to us. We operate across all of it — kerbside, forecourts, driveways, car parks.
Stopped by the kerbside anywhere around Hurlford?
Some people find no safe spot to pull over at all. If you noticed after setting off and ended up on the verge on Leven Court, or in a lay-by somewhere with the hazard lights going, that is a normal call for us instead of a rare one.
Whether you stay by the motor or step clear of it hangs on if sitting nearby seems sensible. It will usually oblige. A diesel running on petrol limps along very willingly, and that is the catch: start it up to reach somewhere safer and that mixture goes further into the system with every mile covered. However difficult the location, it's no trouble for us to come to it, and that is a lot better for the vehicle than pressing on.
A few miles on petrol in a diesel: what next?
Here is where the M77 comes in — under 5 miles from Hurlford. A drop in power, a rough idle, some smoke: those are the signs when they come, rather than a neat stop — and a wrongly fuelled diesel will usually get you onto it and some way along before anything seems wrong at all.
Pull off at the next sensible junction, switch off, and don't start the car to reposition. Long trip? Anything near the under 25 miles to the nearest city and you should suppose the lot — filter, pump, injectors, all of that reached by the contamination. Say that on the call, because it alters what goes in our van.
All about Hurlford
Hurlford is a village situated on the banks of a river in East Ayrshire, with a relatively low elevation of 38 metres. Hurlford lies near the larger settlements of Crookedholm and Bellfield, and is also close to New Farm Loch. Hurlford is located approximately 20 miles from Glasgow, making it a commuter base for the city. Hurlford has a mix of housing types, but flat accommodation is predominant.
What follows when our engineers reach you around Hurlford
- Our technicians ask first, quote after. What was put in? How much? Has the engine run? Those responses change what the work really is.
- The contaminated mixture comes from that tank.
- Our engineers rinse your fuel lines and clear the fuel filter, so what is remaining in the fuel system is not what started the problem.
- Fresh diesel goes in, and then the system gets primed.
- Your engine is turned on and checked to make sure it runs correctly on fresh diesel.
After that it's ready to pull away. There is no need for a garage at any point, as the work is all done where your car is, and when it's noticed early, permanent damage is very rare.
A separate job: AdBlue in a diesel tank in Hurlford
Never fire it up: that first instruction stands whether what got in was AdBlue or petrol. What changes is this fault itself. The protection a fuel system depends on gets stripped away by petrol, which thins your diesel. AdBlue? Urea dissolved in water. Tip that in with your diesel and you get rust instead, plus deposits.
We handle both, and AdBlue removal in Hurlford has its own page with the detail — including why it's frequently the more serious of the two.
What a petrol-in-diesel fuel drain will cost around Hurlford
Frankly, no single number fits on a page like this. The job varies. Here is what changes it:
- Has it been started or driven? Nothing else matters for as much.
- The tank's capacity, set against how much of the wrong fuel got into it.
- AdBlue or unleaded, whichever went in.
- Where your car is, and whether a van can sensibly reach and work on it.
Tell us what the vehicle is, how much went in, and if the engine has run. A straight answer comes back, not a range. If it isn't pressing — your car is at home and going nowhere — is fine too.
Petrol in diesel queries from Hurlford drivers
I'm on a forecourt in Hurlford. Can you drain the car here?
A fair share of this work takes place there, so yes. Our engineers attend Asda and the other forecourts nearby all the time, with the station's agreement — tell us which one you are at when you phone and we will tell you whether we can work there.
Is there a sensible quantity of petrol in a diesel?
It rests on the proportion rather than the litres, and a lot more on whether your 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 blend been pulled right through, or has it not?
Petrol in my diesel, and I have driven the car
Switch off somewhere safe, and keep it that way after you stop. Driving moves the issue along — out of that tank, into the pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one really helpful thing left to you isn't restarting the car.
My warranty — does a fuel drain void it?
A drain and flush carried out properly is not an alteration and does not cancel a manufacturer's warranty. Another good reason to leave it turned off: running a diesel on petrol is the thing likelier to cause a dispute with one.
Adding two-stroke oil, then driving home
Two-stroke oil solves a different problem, and an old one at that. Nothing it does puts back what petrol thinned. No. That tank still has petrol in it after that, and your pump still has to put up with it.
Do I need a main dealer for petrol in a diesel?
You don't need one. Your car is drained and cleaned wherever it is, with no need to take it to a franchised dealer.
You, and the car, still together?
That engine remains off.
Already driven it? Then stop somewhere safe, switch off, and let the car remain that way. Cold and stationary, a vehicle is in the best place available — and motorists fear this far more than the recovery rate warrants.
