Horn Smithies: Put Petrol in a Diesel Car?
Do not turn on your engine. If the fuel is still in the tank and the motor has not yet been started, a drain is almost always all it needs — and that is settled in the following few minutes, not by how much got in. Petrol in Diesel drains and cleans wrong-fuelled cars where they are, all over Horn Smithies and the rest of Merseyside, on the forecourt, by the roadside or on a private drive. Just one call to us is plenty: our team will explain what comes after this. Do that right away.
What to try first about petrol in a diesel
- Don't fire it up. Fired up all the same? Then never depend on it. Diesel in a petrol vehicle normally cannot run, and so the person stops and the wear stops with them. Petrol in a diesel? It starts. It ticks over. It drives off fine, for a couple of miles. Drivers get that confused. It isn't okay — the fuel system is wearing down every mile you drive.
- Leave your ignition alone also. Diesel does two jobs: it combusts, and before it ignites it lubricates that high-pressure fuel pump and its injectors. Petrol does the first and not the second. Flicking the ignition on is frequently sufficient to prime your system, which moves that petrol out of that tank then into just those components.
- Topping up gets rid of nothing. It hands you a fuller tank of the same blend, since a diesel fuel system won't accept petrol by percentage the way that guidance presumes — so do not put diesel on top to water down it. Type is beside the point too: super unleaded is petrol.
- Remain where you are if you safely can. A car that hasn't moved is the quickest one to deal with, and we'd sooner come to a tricky location than have it started. If you're pulled up on the verge on Heath Road, turn those hazards on and leave it there.
- Before you call, have your location. Anything closest to you with a name on it, plus a postcode that starts L36 3 — that's what determines whether the van shows up or circles.
- Three facts settle the entire visit: the liquid you put in, the ballpark amount of it, plus whether anything has been going since. The line is 0333 366 0103.
At a forecourt: removing petrol from a diesel
Much of this job begins at a pump, which means a good chunk of that is completed there. Our technicians work on garage forecourts regularly, with the owner's permission, so if you're still at Shell that's normally where the drain takes place.
Before your motor has run — a garage is the single setting the mistake ends up halted. Our technicians can still put it right where it is, even away from the pumps. In a car park, on a private drive or in a lay-by, the car has been switched on and driven there, and that sucked fuel through the fuel filter then into the high-pressure pump, all the way from the tank. None of that is a catastrophe, but the flush then has to reach past the tank to the fuel lines and the filter, and the few seconds between seeing your receipt and going for your key are what decide that.
Attendants will usually help out pushing it away from the petrol pump, which lets the next customer get by. Accept the assistance. Cranking the car to shift four vehicle lengths isn't.
Horn Smithies and the towns beside it
The same runs bring us to Fincham, Woolfall Heath, Huyton Farm, Page Moss and Roby besides Horn Smithies, which is a residential suburb.
Not on the list? It says nothing. The names above are only the nearest few, and the majority of locations around Merseyside have a page of their own somewhere on our site. Contact us and enquire rather than assuming, above all when you are on a border or somewhere your satnav gets wrong.
The map shows the patch the page spans. We work roadside, at forecourts, on driveways and at car parks across all of that, and the vehicle does not need to come to us.
Move it out of the gateway and deal with it later — that is what somebody will say, and it's wrong. Parked on the zig-zags outside Park View Academy, a misfuelled diesel Peugeot 308 is a hassle and nothing worse. Started three more times for courtesy, it's no longer a tank fault but a fuel system one, because priming occurs with every start and more petrol goes past the filter toward the pump. Let everyone complain. Ring us.
Try the trip home from The Old Bank? Don't. It will start and it will drive off quite happily, which is the problem — a diesel on a diluted tank behaves usually whilst wearing down the components your fuel should be lubricating. Park the Nissan Qashqai then phone us.
Out there normal, back gutless. If that was the run to Jubilee Park, look at the tank. Diesel gets thinned by petrol, and thin fuel seeps past the close gaps supposed to build injection pressure — so every additional mile the diesel Audi A4 covered, the less pressure it held onto. Somewhere sensible, switch off, call us.
Rarely the trouble, the place. On-street is the most common place we work, and a tight parking bay is far preferable to a car that has been driven somewhere more handy. What does help, when you ring from close to Trinity Church, is three things: the side the filler is on, whether a van can park beside without blocking the road, and if anything has run since you filled up. Then your Mercedes C-Class gets emptied, the filter changed where a usable one exists, the lines cleaned and fresh fuel put through the whole circuit — since by now the worst of that is in the fuel lines, not the tank.
Petrol in a diesel does its harm as a ratio, which is the reason we ask at all: the same few litres sitting 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 resists igniting under pressure — the opposite of what a diesel needs — so a stronger mix rattles more, smokes more, goes flatter. None of which means you need an answer ready. Nearly nobody knows how full your tank was in a car collected two days ago, and our engineers work that out on site. Do phone the hire or company firm first, though: some contracts want them to authorise the work, and that's far faster settled before than after. Then call us about the Dacia Duster near St Aloysius.
Stuck by the roadside anywhere around Horn Smithies?
Not everybody gets a chance to stop anywhere safe. Hazards on in a lay-by somewhere, or pulled onto the verge of Terminus Road since you noticed after setting off — our technicians take that call regularly enough that it's the normal kind.
Okay where you are? Stay beside it. Not fine? Move out and clear of it. Don't fire up your motor to limp the vehicle somewhere handier — a diesel running on petrol will frequently oblige, and every mile it obliges for is dragging the blend further into the fuel system. A technician coming to a difficult location is no bother for us, and it's much better for the vehicle than driving on.
Driven it already? Pull in, and check below
Here is where the Huyton Spur comes in, under a mile out of Horn Smithies. A misfilled diesel will usually take you onto it and some distance along before anything seems wrong, while the symptoms when they arrive are normally a loss of power, a rough idle and smoke rather than a neat stop.
Get off at the next safe junction, switch off, and don't restart it to reposition. Long trip? Anything approaching the under 10 miles to the nearest city and you should assume the lot — filter, pump, injectors, all of that arrived at by the mixture. Say that on the phone, since it alters what goes in the van.

What our engineers do when our engineers reach you in Horn Smithies
- We find out what got in, how much, and whether the motor has run. The replies alter the work, which is why we ask before giving a price.
- The contaminated fuel comes from your tank.
- Lines purged, filter cleared. Whatever is left later on isn't the thing that created the trouble.
- We put fresh diesel in and prime your system.
- When it is started, our technicians make sure it runs properly on clean diesel.
At that point it is ready to pull away. Everything is done where the car is, so it never needs to go to a garage, and when it has been noticed soon, permanent damage is very unusual.
AdBlue in your diesel tank by mistake, around Horn Smithies?
Never start it: that first rule holds whether what was put in was AdBlue or petrol. What changes is this fault itself. Weakened diesel, and no protection left for the fuel system that depends on it. That's petrol. Rust and build-up are what a diesel tank gets instead, since AdBlue is urea in water.
Both are ours. There's a separate Horn Smithies page for AdBlue removal, with the detail 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 Horn Smithies?
Our engineers can't put one price on this page honestly, as the job is not one job. What moves it:
- Whether your engine has been started or driven. This is the key one.
- How much of the wrong fuel was put in, judged against how much your tank can hold.
- AdBlue or petrol, whichever got in.
- Whether a van can safely reach the vehicle and work on it, which depends on where your car is.
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. Car at home, going nowhere, nothing time-critical about it — is fine for that.
Horn Smithies motorists ask us these about petrol in diesel
Can you do a fuel drain at a petrol station around Horn Smithies?
A fair share of this work gets done there, so yes. Routinely, provided the site consents: Asda, plus every other forecourt nearby. Say on the phone where precisely you have stopped. Whether our engineers can work in that spot is something our engineers answer on the spot.
A few litres of petrol in a diesel — too much?
Proportion settles it rather than litres — and more than either, whether the motor has run. Five litres in an almost empty tank is a different situation from five in a full one — but either way, the thing that decides how much work is required is whether that mix has been drawn through the fuel system.
Petrol in my diesel, and I have driven the vehicle
Stop safely. Off. Nothing after that. Driving moves the problem along — out of the tank, into the pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one genuinely valuable thing left to you isn't restarting the car.
Fuel drains and manufacturer warranties
It's not a modification, so a drain then flush carried out correctly doesn't invalidate a manufacturer's warranty. Running a diesel on petrol is the thing likelier to cause a disagreement with one, which is another reason to leave the car turned off.
Adding two-stroke oil, then driving home
Two-stroke oil solves a distinct problem, and an old one at that. Nothing it does puts back what petrol thinned. No. The tank still has petrol in it later on, and your pump still has to cope with it.
A main dealer for petrol in a diesel — necessary?
There's no need to bring it to a main dealer, because our engineers drain and clean your car wherever it is.
Still with your car?
Turned off is how it stays.
Already driven it? Then stop somewhere safe, turn off, then let the vehicle stay that way. Cold, stationary, going nowhere: that's the best position to be in. People fear this much more than they need to.
