Brucehill: Put Petrol in a Diesel Car?
Do not start your engine. If the fuel is still sitting in that tank and the engine has not turned over, a tank drain is nearly always all it takes — and that's settled in the next few minutes, not by how much went in. Petrol in Diesel drains and cleans misfuelled cars where they sit, all over Brucehill and the rest of West Dunbartonshire, on the forecourt, by the roadside or on a driveway. Ring us and then our technicians will show you what follows after that before you do any more.
Petrol in a diesel: what to do now
- Feed a petrol engine diesel and it will usually not run at all, so the person stops there and so does the harm. Feed a diesel petrol and the engine starts, it idles, it moves off — fine for a few miles. Drivers have that reversed, which is the thing they get wrong about petrol in a diesel especially. So do not crank it. And if started, don't believe it: the fuel system is wearing while you drive.
- Switching the ignition on frequently primes that system, and priming is what pulls petrol out of your tank and into your pump and injectors. Those are the components diesel keeps oiled on its way through, before it combusts. Petrol does the burning and none of the protecting. Leave your ignition be.
- That advice assumes a diesel fuel system copes with petrol by percentage. It will not. Add diesel on top and nothing at all is cleared; what you have is a bigger tank of the same mix. And no, the octane makes no difference — super unleaded is simply petrol.
- We would rather come to a tricky place than have it started — so if you safely can, stay put. Nothing is quicker to handle than a car that hasn't moved. On the verge on Hill Street, that means hazards on and keep the vehicle.
- A van turning up instead of circling hinges on two things: a postcode beginning G82 4, and whatever is nearest to you with a label on it. Get both prepared before you call.
- Dial 0333 366 0103. Prepare for three queries — what got in, roughly how many litres, and if your car has been run. Those replies decide everything that follows.
Can petrol be drained from your diesel at the forecourt?
Plenty of this work starts at the pump, so a big chunk of it ends up completed on site. If you are still at the forecourt at Murco, that's usually where the drain takes place — our technicians work on station forecourts all the time, with the owner's consent.
No place but the forecourt can the mistake be halted with the motor still untouched. The few seconds between reading your receipt and going for your key settle how much needs rinsing. Anywhere other than a forecourt — a car park, a private drive, a lay-by — the car was started and moved to get there, so fuel was sucked from that tank, through the filter then into your high-pressure pump. That means the lines and your filter require cleaning as well as your tank. It's not a disaster, and our technicians can still put it right where the vehicle stands.
Away from the pump, the next motorist can get by — so yes, let the staff help you wheel it. Worth it. Four vehicle lengths isn't worth the risk.
Can we cover your corner of Brucehill?
Brucehill is a residential suburb, and so our technicians are out to the town and to the areas around it on the usual rounds: Dennystown, Kirktonhill, Castlehill, Dumbarton and Townend.
We still come. Those places above are only the immediate neighbours, and a page is there for nearly all towns around West Dunbartonshire, so an absence from the list isn't an absence from the coverage. Ring us to ask rather than presuming, particularly when you're on the border or anywhere your phone misreads.
The map outlines the ground this page includes. We operate at the roadside, on forecourts, on driveways and in car parks across all of it, and the vehicle does not need to move to us.
Each restart primes the fuel lines and drags more petrol through your filter then into the pump. So a misfuelled diesel Nissan Qashqai on the zig-zags by the local primary school is an inconvenience, while the same motor fired up three more times to be courteous is a fuel system instead of a tank. A passer-by will advise you to move the vehicle out of the gateway and sort it out later. Don't. Stay put, let people grumble, then call us.
Your Audi A4 stays where it is in the car park by The Lennox for the whole job, which usually goes like this. First we ask what was put in, approximately how much, and whether the engine has run since, given that most of the work rests on those replies. That tank is emptied of the contaminated mixture, the fuel lines are flushed, and the filter comes off if it is a serviceable one. With fresh diesel in and the system primed, the vehicle is started and checked, and once it's running smoothly you pull away.
Your pump isn't turning, so whatever your diesel Mercedes E-Class did on the way to Cunninghame Graham Memorial Park, none of it is going on now. Nothing is getting worse while it waits. Take your time over this — but never drive the vehicle home to buy any.
Three things help when you call from close to St Michael's RC Church: which side the filler is on, whether our van can pull up alongside without blocking the road, and whether your engine has run since you filled up. On-street is the commonest spot our technicians work, and so the spot itself is hardly ever the issue — we'd far rather deal with a narrow parking bay than with a vehicle that has been driven to somewhere more convenient. We'll drain the BMW 1 Series, change your filter where there is a usable one, flush your lines and put fresh fuel through the full circuit, as by this point the worst of it is sitting in the lines rather than in your tank.
By now your tank is the least of it. Run a diesel and that mixture goes into your filter, into the fuel lines, into the pump, into its rail — and none of that leaves with the tank contents. A diesel Kia Sportage that made it close to The Church of Jesus Christ of Latter-day Saints wants its system flushed. Emptying is not the same thing.
Kerbside stops around Brucehill
The opportunity to stop somewhere suitable does not come to everyone. If you realised after setting off and ended up along the verge on Bontine Avenue, or at a lay-by somewhere with your hazards on, that is a routine call for us rather than a rare one.
Out of your car while it isn't sensible to be inside, beside it when it is. It will usually oblige. A diesel running on petrol limps along perfectly willingly, and that's the trouble: restart the vehicle to get to somewhere handier and that blend goes further into your fuel system with every mile travelled. We will take our van to a difficult place without any bother, and for the vehicle that's much better than driving on.
A few miles on petrol in a diesel: now what?
The M8 is the road which matters now, and it runs under 3 miles from Brucehill. Some distance along, and onto it in the first place: a misfilled diesel will usually manage both before anything feels wrong. What you get then is seldom a clean stop. Power falls away, your idle gets lumpy, and there may be smoke.
Pull off at the first sensible exit, turn off, and do not restart the car to move it. On a longer run — anything close to the under 15 miles to the nearest city — assume the mixture has been through your filter, the pump and your injectors, and say so when you phone. It alters what we bring.
Brucehill itself
Brucehill is a coastal suburban area in West Dunbartonshire, situated near the Clyde Estuary at an elevation of 42 metres. Brucehill lies within the wider Glasgow urban area, approximately 14.7 miles from the city centre, and is close to nearby places such as Dennystown and Kirktonhill. Brucehill is characterised by its predominantly flat-type housing and a population of around 3248 residents.
The call-out in Brucehill, step by step
- The answers alter the work, which is why our engineers ask before pricing: what got in, how much of it, and whether the engine has run.
- Out goes the polluted fuel.
- Fuel lines are rinsed through and the filter cleared, leaving nothing in the system that started any of this.
- We put fresh diesel in and bleed the system.
- It's run with new diesel in it, and our engineers confirm that it's running smoothly.
The car is then ready for you to pull away. All of this is done where the vehicle is, so it never has to go to a workshop, and when it has been spotted quickly, permanent damage is very uncommon.
AdBlue in the diesel tank by mistake, around Brucehill?
AdBlue rather than petrol? Then the first instruction is unchanged — your motor remains off — while this problem underneath it is a different one altogether. The lubrication a fuel system depends on gets taken away by petrol, which weakens the diesel. Urea dissolved in water, AdBlue, and in a diesel tank that leads to rust and residue.
Our technicians cover both, and AdBlue removal in Brucehill has its own page with the full story — including why it is usually the more significant of the two.
Brucehill costs for a petrol-in-diesel fuel drain
What changes the figure is laid out below, as the job is not one job and our engineers can't honestly put a single figure on this page.
- Whether your motor has been started or driven. This is the main one.
- How much of the wrong fuel got in, judged against how much that tank can hold.
- The kind of liquid in the tank, petrol or AdBlue.
- Whether a van can sensibly reach your vehicle and work on it, which depends on where your car is.
The car, the quantity, whether it has run — give us those and the answer comes back firm rather than as a range. Motor at home, going nowhere, nothing urgent about it — is fine for that.
Petrol in diesel queries from Brucehill drivers
I am on a forecourt in Brucehill. Can you drain it here?
Yes — forecourts are where a big portion of this takes place. Our engineers work at Morrisons 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'll tell you whether our engineers can work there.
A few litres of petrol in a diesel — too much?
Ratio decides it rather than litres — and more than either, whether the motor has run. What determines how much work is needed is whether that mixture has been drawn through the fuel system — since although five litres in an almost empty tank is a separate situation from five in a full one, either way that is the query.
I drove it after putting petrol in my diesel. What now?
Turn off somewhere safe, and keep it that way after you stop. It's salvageable a lot more commonly than drivers expect, even though driving is what takes the trouble from the tank into the pump and injectors — and the single most useful thing you can do now isn't restart it.
Fuel drains and manufacturer warranties
A drain and flush carried out correctly is not a change and doesn't invalidate a manufacturer's warranty. Another reason to leave it switched off: running a diesel on petrol is the thing more likely to cause an argument with one.
Two-stroke oil in that tank, and then home?
No. Two-stroke oil is an old remedy for a separate problem and it does not restore what petrol has thinned. Later? Still petrol in that tank, and a pump that has to cope with the stuff.
Does petrol in a diesel have to go to a main dealer?
There's no need to take it to a main dealer, as we drain and flush the car wherever it is.
Still with your vehicle?
Shut off is how the car remains.
Switch it off somewhere safe and keep it off, if you have already driven it. A parked, cold motor is the best place to be in, and this is recoverable from a lot more regularly than drivers assume.
