Put Petrol in a Diesel Car in Dundonald?
If you have not fired up the motor as yet, don't. A fuel drain and nothing else is almost always what a motor needs while the petrol is still in the tank and your engine has not run, which is why it's the next few minutes that count, not how much was put in. Petrol in Diesel goes to your car wherever it has ended up in Dundonald or the remainder of South Ayrshire, on the forecourt, at the roadside or on a private drive, and drains and flushes it there. Ring us before anything else starts, so you'll learn what follows after that.
What to do next about petrol in a diesel
- While you drive, your pump and the fuel injectors suffer. That's why you do not fire it up, and why you never trust it once it has started. The trick about petrol in a diesel especially — the bit people get wrong — is that it drives off normally for the first mile or two. Diesel in a petrol motor generally won't run at all, which stops the driver and stops the damage with them. This one lets you drive on.
- Flicking the ignition on usually primes that system, and priming is what pulls petrol out of that tank then into the pump and injectors. Those are the parts diesel keeps lubricated on its way through, before it burns. Petrol manages the burning and none of the protecting. Leave the ignition off.
- That guidance supposes a diesel fuel system copes with petrol by percentage. It does not. Add diesel on top and nothing at all is taken out; what you end with is a larger tank of the same mixture. And no, the octane makes no difference — super unleaded is still petrol.
- We would sooner travel to a difficult spot than have it started — so if you sensibly can, sit tight. Nothing is simpler to handle than a car that hasn't moved. On the verge on Richmond Terrace, that means hazards on and keep the car.
- Before you ring, have your position. Anything closest to you with a sign on it, plus a postcode starting KA2 9 — that is what settles whether the van turns up or circles.
- Dial 0333 366 0103. Let us know what went in, approximately how many litres, plus whether your car has run. Those three replies determine the whole job.
The drive back would more or less double it, for no gain at all. One commute has already forced a real quantity of petrol-thinned diesel through the high-pressure fuel pump of your Volkswagen Passat. So keep it where it is. Call us from the platform if that's handier — no one needs you standing over the vehicle at Barassie while our engineers work, and tonight is better than finding out on Monday.
The difficult part is that bay, not the fuel. Cars either side of you, a trolley shelter behind, and from time to time a height limit on the way in that settles whether a van can reach you at all — so when you phone from a car park like the one outside The Co-operative Food, mention how much room there is around you and which way round your car is. Those our technicians cover often. Should there be no room to work next to your diesel Renault Clio, it gets rolled with the engine off, and not out of pedantry over a few seconds of running: priming happens at every start, more of the blend exits the tank for the pump, and two shunts into a roomier bay have quietly made a harder job of what was merely a motor standing still.
Your diesel Ford Focus will have seemed entirely normal on the way back from the local primary school. They do, and that is the trap with petrol in a diesel instead of the other way round. Put diesel in a petrol vehicle and it generally won't run, so the person stops and the damage stops with them. Put petrol in a diesel and it fires up, idles and drives off as though nothing has happened — all the while the high-pressure pump does its work without the protection your fuel is supposed to be giving. Nothing warns you, because from behind the wheel there is nothing to warn you about. Phone us with roughly how far you drove and how hard you pushed it; the second one matters more than the first.
Why so blunt about leaving your keys alone? Since your pump is before the injectors, and a worn one sends whatever it gives off onward with your fuel. Phone us. Leave the BMW 5 Series by Dundonald Parish Church.
The smaller petrol nozzle fits a modern diesel filler neck with practically no resistance at all, which makes this mechanical not sloppy. Strange locations see most of that for that reason. So: topped up near War Memorial without thinking, in a diesel Citroen C3 you have had for two days? Ring us where you are. Hire and courtesy cars usually get driven further before anybody notices, and miles determines how much petrol ends up at the injectors.
Draining petrol from a diesel on a forecourt
Much of the job begins at a pump, which means a big share of it ends up completed on site. If you are still on the forecourt at Esso, that's normally where this drain happens — our technicians work on petrol station forecourts all the time, with the station's agreement.
Nowhere else except a forecourt can the mistake be halted with your motor still untouched. Fuel pulled out of the tank and through the fuel filter, right to the high-pressure pump, is what happens when your engine is fired up and your car is driven to where it is now: the car park, the private drive or the lay-by, anywhere other than the forecourt. So the flush includes the filter and the fuel lines together with the tank. That is still not a calamity, and we sort it out where the car is. What decides it is whether the key was reached for in the seconds after the till receipt was read.
The staff will generally offer to wheel it clear of the petrol pump so the next driver can get through. That's worth doing. Four car lengths is not worth the risk.
Places we reach in Dundonald
Laigh Hillhouse, Drybridge, Collennan, Symington, Gatehead — each of them on the runs that bring us across to Dundonald as well, a coastal village.
If yours isn't on the list it doesn't mean we do not come — there are separate pages for nearly all towns in South Ayrshire, and the ones named above are simply the immediate neighbours. Ring us to enquire rather than presuming, particularly where you are on the border or somewhere your satnav misreads.
That map is the ground this page includes. All of it is ground we work: a kerbside, a forecourt, a driveway, a car park. You do not bring the car anywhere.
Stopped on the roadside anywhere in Dundonald?
Some drivers get no safe place to pull over whatsoever. A common call for us instead of an unusual one: realised after setting off, finished up by the verge on Main Street or in a lay-by with the hazards going.
Sit by your car while it's wise to wait in it, yet out of the car if it isn't. It will often oblige. A diesel running on petrol limps along very willingly, and that's the catch: fire it up to reach somewhere handier and the mix goes further into your fuel system with every mile driven. A technician coming to a difficult spot is no bother for us, and it's much better for the car than carrying on.
Petrol in a diesel, and the vehicle has moved
This is where the local M77 comes into it — under 10 miles away from Dundonald. A wrongly fuelled diesel will usually take you onto it and some distance along before anything seems wrong, while the symptoms when they appear are normally a loss of power, an uneven idle and smoke rather than a clean stop.
Pull off at the first sensible exit, turn off, and do not restart it to move it. On a longer run — anything near the under 25 miles to the closest city — take it the mixture has been through the filter, the pump and the injectors, and mention it when you phone. It affects what our technicians bring.
A bit about Dundonald
Dundonald is a coastal village in South Ayrshire, situated near the towns of Troon and Irvine, with Laigh Hillhouse and Drybridge nearby. Dundonald has a population of around 1617 people and is characterized by its terraced housing. Dundonald sits at an elevation of 36 metres, looking out to the coast of the Firth of Clyde. Dundonald is located approximately 24 miles from Glasgow and 335 miles from London.
The visit in Dundonald, step by step
- Three things get asked before any price — your fuel that went in, the amount, and if anything has been run since. Each answer alters the work.
- We drain that tank of all the polluted mixture.
- Our technicians flush your fuel lines and clear the fuel filter, and so what is remaining in the system is not what started the issue.
- We put clean diesel in and bleed the fuel system.
- The motor is fired up and checked to be sure it runs smoothly on new diesel.
From there, you're ready to drive away. All of this is done where the car is, so it never has to be taken to a workshop, and when it has been caught early, lasting damage is very uncommon.
AdBlue in your diesel tank by mistake, around Dundonald?
The issue isn't the same, though the opening instruction is — don't start it — if what was put in was AdBlue instead of petrol. The lubrication a fuel system depends on is taken away by petrol, which thins the diesel. AdBlue is urea in water, and in a diesel tank it brings corrosion and residue instead.
Frequently the more serious of the two, AdBlue — and the full story lives on its own Dundonald page. Both are ours to deal with.
What a petrol-in-diesel drain costs around Dundonald
One price would not be fair here, because this is not one job. These are the things that change it:
- Whether your engine has been started or driven. This is the big one.
- The tank's capacity, set against how much of the wrong fuel went into it.
- AdBlue or petrol, whichever went in.
- Whether a van can safely get to the vehicle and work on it, which hinges on where the car is.
The vehicle, the quantity, whether it has run — give us those and the answer comes back clear and not as a range. If it isn't pressing — your car is at home and going nowhere — works too.
Questions we get about petrol in diesel around Dundonald
Fuel drains on a Dundonald petrol station forecourt
Yes — forecourts are where a fair part of this happens. Tell us which one you are at when you call and we'll tell you whether our engineers can work there. With the owner's consent we work at BP and the other forecourts around town all the time.
Is there a sensible quantity of petrol in a diesel?
Proportion settles it instead of litres — and more than either, whether your engine has run. What settles how much work is needed is if that blend has been drawn through the system — because although five litres in a nearly empty tank is a separate case from five in a full one, either way that's the question.
Already driven it with petrol in your diesel? What now?
Stop sensibly. Off. Nothing after that. It's recoverable a lot more commonly than motorists expect, even though driving is what moves the issue from that tank into your pump and injectors — and the single most helpful thing you can do now is not restart it.
My warranty — does a fuel drain void it?
No. Carried out properly, draining and flushing is no change at all, and the warranty from your manufacturer is untouched by it. What is likelier to start an argument is a diesel that has been run on petrol. One more reason for your engine to remain off.
Adding two-stroke oil, then driving home
What petrol has thinned is not replaced by two-stroke oil, which is an old remedy for a different fault. So no. That tank still has petrol in it after that, and the pump still has to cope with it.
A main dealer for petrol in a diesel — needed?
Not at all. Our technicians drain and flush the car wherever it is, so there's no need to bring it to a franchised dealer.
You, and your vehicle, still together?
Your engine stays off.
Driven it already? Then somewhere sensible, stop, turn off, and no restarting the vehicle later. A still, cold vehicle is the best position to be in, and this is recoverable from much more regularly than motorists fear.
Throughout South Ayrshire and in Dundonald: on-site fuel draining, at home or on the forecourt or at the roadside.
