Put Petrol in a Diesel Car in Tarbert? Don't Start It
Petrol in Diesel drains and cleans wrong-fuelled vehicles where they are, on the forecourt, at the roadside or on a drive, all over Tarbert and the rest of Argyll and Bute. The first thing to do is not to turn on your engine. When your engine has not yet run and the petrol is still sitting in that tank, a fuel drain is nearly always all it requires, and the following few minutes settle that, not how much got in. One ring to us will be plenty: our technicians will show you what comes next. Make this right away.
Petrol in a diesel: what to do next
- Never start the car. Fired up anyway? Then do not rely on it. Diesel in a petrol car usually can't run, so the driver stops and the wear stops with them. Petrol in a diesel? It starts. It idles. It moves off normally, for several miles. Motorists get that muddled. It's not okay — that fuel system is grinding every mile you cover.
- Flicking the ignition on commonly primes your system, and priming is what moves petrol out of that tank then into your pump and injectors. Those are the parts diesel keeps greased on its way through, before it burns. Petrol manages the burning and none of the lubricating. Leave the ignition alone.
- Never pour diesel on top to dilute it. A diesel fuel system will not accept petrol by percentage the way that advice assumes, and topping up gets rid of nothing — it just gives you a larger tank of the same mix. The octane makes no difference either: super unleaded is just petrol.
- Wait where you are if you sensibly can. A motor that has not moved is the easiest one to handle, and we'd rather get to a tricky location than have it started. If you are pulled up on the verge on Brunswick Street, put those hazards on and keep the vehicle there.
- Our van arriving instead of circling rests on two things: a postcode starting PA29 6, and whatever is closest to you with a name on it. Have both prepared before you dial.
- Three replies determine the entire job: the liquid you put in, the approximate measure of it, plus whether anything has been going since. The line is 0333 366 0103.
How far you went is what our technicians ask about, not how long the vehicle has been sitting — and this is why. Diesel does two jobs on its way through a motor: it combusts, and before burning it lubricates its high-pressure fuel pump and its injectors. Petrol does the first only. So a hurried fill on the way in, it dawning on you at about eleven, and a diesel Renault Clio parked at the nearest station since quarter past eight shows those few miles were covered with the pump labouring on a fuel drained of a lot of its protection. Ring us and keep the vehicle exactly where it sits.
Move the vehicle out of the gateway and deal with it later — that's what a passer-by will say, and it is wrong. Parked on the zig-zags at the local primary school, a wrongly fuelled diesel Nissan Qashqai is a nuisance and nothing worse. Restarted three more times for courtesy, it is no longer a tank problem but a fuel system one, since priming takes place with every start and more petrol goes past the fuel filter toward your pump. Let them moan. Call us.
You head off at the end, once we have started the car and made sure it runs properly on fresh diesel, with the fuel system primed. Before that, in the car park outside the Corner House, the tainted fuel comes out of your tank, your lines get rinsed and the filter comes off where your Audi A4 has a replaceable one. Everything begins with three questions when we get to the car: what was put in, how much of it, and whether it has been fired up since.
A vehicle you picked up two days ago gets driven further before anybody spots anything, which is the hire and courtesy problem in one sentence — and how far it went is what determines the amount of petrol reaching your injectors. Nothing sloppy about the mistake itself: a modern diesel filler neck takes the narrower petrol nozzle with almost no resistance, and so strange places see most of these. Call us from wherever you are, near Tarbert Loch Fyne Parish Church or not, and we'll head to the Vauxhall Astra.
By this point the tank isn't where most of the damage is. Once a diesel has run, that blend is in the fuel filter, the lines, your pump and the rail — and it doesn't come back out with that tank contents. A diesel Ford Kuga that got close to War Memorial needs the circuit flushed, not drained.
Can petrol be pumped from a diesel on the forecourt?
It kicks off at a forecourt, generally. Regularly the work wraps up on site too. The drain usually takes place on the spot. Still on the forecourt at the nearest petrol station? Given the station's permission, that is a place our technicians work, and regularly.
No place but a garage can this be halted with your engine still unstarted. Anywhere else — a car park, a drive, a lay-by — the car was fired up and moved to get there, which means fuel was pulled from the tank, through the filter and into your high-pressure pump. That's not a disaster, and our technicians can still deal with it where it is. It does mean your lines and the fuel filter need cleaning as well as the tank, and that is determined by the few seconds between reading the till receipt and reaching for your key.
Attendants will normally chip in pushing it away from the pump, which lets the next customer get through. Welcome the assistance. Cranking it just to move four vehicle lengths is not.
Coverage around Tarbert
Tarbert is a coastal village, and so we go out to the town and to the areas near it on the usual runs: West Tarbert, Torinturk, Pollphail Village, Portavadie and Melldalloch.
Our technicians still come. The names above are just the immediate neighbours, and a page exists for nearly all places around Argyll and Bute, so an absence from the list isn't an absence from the coverage. Near a border, or somewhere your phone struggles with? Contact us to check rather than presuming.
Look at our map for the ground shown here. Kerbside, forecourt, driveway, car park: every bit of that is territory our technicians work on, and none of it asks the vehicle to travel to us.
Broken down by the roadside near Tarbert
Some people get no suitable place to stop at all. Hazards going in a lay-by somewhere, or stopped on the verge beside Harbour Street as you noticed after setting off — our engineers take that call so often that it's the ordinary kind.
Safe there? Stay with it. Not safe? Move out and clear of it. Every mile a diesel obliges you for on petrol pulls that mix further into your fuel system — and oblige it often will, which is why your motor does not get restarted to limp somewhere handier. However difficult the location, it's no bother for us to come to it, and that's far better for the car than pressing on.
Run it already? Pull in, then read below
Your M8 is the one which matters now, and sits under 50 miles from Tarbert. Lost power, a lumpy idle, smoke: those are the signs when they arrive, rather than a clean stop — and a misfuelled diesel will often get you onto it and some distance along before anything feels wrong at all.
Never start it to reposition. Get off at the next sensible junction then switch off. It changes what our engineers bring, so say so when you phone: on a longer trip — anything close to the under 50 miles to the closest city — take it the contamination has been through the fuel filter, your pump and the injectors.
Where is Tarbert?
Tarbert is a small coastal village in Argyll and Bute, situated on the shores of East Loch Tarbert at a low elevation of around 7 metres. Tarbert lies within a scenic area of western Scotland, near the villages of West Tarbert and Pollphail Village. Tarbert is home to a population of approximately 844 people, predominantly residing in flats. Tarbert is located near the Kintyre Peninsula, with Glasgow being the nearest major city, about 45.7 miles away.
Once our engineers get to you around Tarbert: what we do
- Our technicians ask first, price after. What got in? How much? Has your engine run? Those answers alter what the work really is.
- Away comes the tainted fuel.
- Fuel lines are flushed through and the fuel filter cleaned, leaving nothing in the fuel system that created any of this.
- Fresh diesel goes in, and then the system gets bled.
- The engine is started and checked to confirm it runs smoothly on clean diesel.
Your car is then ready for you to pull away. Long-term damage is very unusual when it has been caught quickly, and since all of this is done where the car is, it never has to go to a garage.
AdBlue in a diesel tank around Tarbert is a different matter
The fault isn't the same, though the first instruction is — never crank it — if what got in was AdBlue instead of petrol. Petrol dilutes your diesel and takes away the lubrication your fuel system depends on. AdBlue is urea dissolved in water, and in a diesel tank it brings rust and build-up instead.
AdBlue removal around Tarbert has a page of its own with the detail on it, including why it is frequently the more serious of the two. We deal with both.
What a petrol-in-diesel fuel drain costs around Tarbert
One number wouldn't be fair here, because this is not one job. These are the things that change it:
- Has it been started or driven? Nothing else matters for as much.
- How much of the wrong fuel went in, measured against how much that tank holds.
- The type of liquid in the tank, petrol or AdBlue.
- Where the car is, and whether a technician can sensibly get to and work on it.
A straight answer instead of a range is what you get for telling us three things: your vehicle, the quantity, and if it has run. For your car at home that's going nowhere and isn't time-critical, is fine too.
Petrol in diesel: frequent questions in Tarbert
Fuel drains on a Tarbert petrol station forecourt
Yes — forecourts are where a fair portion of this gets done. Regularly, provided the site agrees: another forecourt nearby, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether we can work in that spot is something we answer on the spot.
How much petrol in a diesel is too much?
Proportion decides it rather than litres — and more than either, whether your engine 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 settles how much work is needed is if that mixture has been sucked through the system.
I drove the vehicle after putting petrol in my diesel. Now what?
Stop safely. Off. Nothing after that. Driving is what takes the issue from your tank into your pump and injectors — but it's salvageable a lot more often than motorists assume, and the single most helpful thing you can do now is not restart the car.
Is a fuel drain going to void my warranty?
It isn't a change, so a drain and flush carried out properly does not invalidate a manufacturer's warranty. An argument over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Adding two-stroke oil, then driving home
No. It belongs to a different problem from a separate era, and petrol has thinned something no oil of that kind puts back. Your tank still has petrol in it later on, and your pump still has to live with it.
Do I need a main dealer for petrol in a diesel?
No. We drain and clean the vehicle wherever it is, so there's no need to bring it to a main dealer.
You, and the vehicle, still together?
That engine remains off.
If you have already driven it, stop somewhere safe, turn it off then leave it off. Cold, parked, going nowhere: that's the best position to be in. People fear this far more than they need to.
