Put Petrol in a Diesel Car in Coleford? Don't Start It
Never turn on the motor. If the fuel is still in that tank and the engine has not turned over, a tank drain is almost always all it requires — and that is determined in the next few minutes, not by how much got in. Petrol in Diesel drains and flushes misfuelled cars where they sit, across Coleford and the rest of Devon, on the forecourt, by the roadside or on a private drive. We will tell you what the next step is. Contact us — it goes before everything else.
What to do first about petrol in a diesel
- Do not fire it up. Fired up anyway? Then never believe it. Diesel in a petrol vehicle usually will not run, so the person stops and the damage stops with them. Petrol in a diesel? It starts. It ticks over. It moves off happily, for a couple of miles. People get that confused. It is not fine — your fuel system is grinding every mile you do.
- Leave the ignition alone as well. Diesel performs two roles: it ignites, and before it burns it greases that high-pressure pump and its injectors. Petrol does the first and not the second. Flicking the ignition on is often all it takes to prime your system, which pulls the petrol out of your tank then into exactly those parts.
- Do not put diesel on top to weaken it. A diesel fuel system does not tolerate petrol by percentage the way that guidance assumes, and topping up gets rid of nothing — it only leaves you a bigger tank of the same blend. The grade makes no difference either: super unleaded is just petrol.
- Stay where you are if you sensibly can. A vehicle that has never shifted is the quickest one to handle, and we'd much rather come to a tricky spot than have it started. If you are pulled up on the verge on Goblin Hill, turn those hazards on and keep the car there.
- Get your whereabouts prepared before you ring. A postcode starting EX17 5 and whatever is nearest to you with a label on it is the difference between the van turning up and our van circling.
- Call 0333 366 0103. Say what was put in, roughly how much, and if the engine has fired. Those three details decide the whole job.
The trip back would more or less double it, for no gain at all. One commute has already sent a real volume of petrol-thinned diesel through your high-pressure pump of your Renault Clio. So leave it where it is. Phone us from the platform if that is quicker — no one needs you standing over the vehicle at Copplestone whilst our engineers get on, and tonight beats finding out on Monday.
Move the vehicle out of that gateway and fix it later — that is what a passer-by will say, and it is wrong. Parked on the zig-zags by Copplestone Primary School, a misfilled diesel BMW 3 Series is a nuisance and nothing worse. Fired up three more times for courtesy, it's no longer a tank problem but a fuel system one, since priming takes place with every start and more petrol goes through the filter on to the pump. Let them moan. Phone us.
Three replies settle much of the work: what went in, roughly how much, and whether the engine has run since. We ask for them as soon as we get to the vehicle in the car park at The New Inn. Then the tainted mixture comes out of your tank, your lines are rinsed, and where your Audi A3 has a serviceable filter, it comes off. When new diesel is in and your system bled, our engineers start it and make sure it runs correctly before you drive away.
We flush the fuel lines instead of only emptying your tank, and the reason is that weakened fuel has already reached the filter and the pump: it was a start and a drive, however short. The distance truly assists — pulled off the forecourt, receipt read, a diesel Ford Fiesta parked up by St Andrew's a few hundred yards later is about as well as this goes once the motor has turned. Call us and leave it off.
The fuel filter, your lines, your pump and the rail: that's where the mixture is once a diesel has run, and it doesn't come back out with that tank contents. So that tank isn't where most of the trouble rests by this point, and a diesel Seat Leon that made it near Colebrooke House needs the system cleared rather than drained.
At a forecourt: draining petrol from a diesel
The job begins at a forecourt, mostly. Frequently the work wraps up on site as well. Our technicians work on petrol station forecourts regularly, with the station's agreement, and so if you are still at Shell that's usually where this drain takes place.
A filling station is the only spot the mistake can be stopped before your engine has run. Fuel sucked out of your tank and through the filter, all the way to the high-pressure fuel pump, is what happens when the motor is switched on and the vehicle is moved to where it is now: the car park, the driveway or the lay-by, anywhere other than the forecourt. So the flush includes your filter and the lines together with your tank. That is still not a calamity, and we deal with it where your car sits. What decides it is whether the key was turned in the seconds after the receipt was read.
The attendants will normally help you wheel it away from the pump so the next customer can get through. It is worth doing. Cranking the car just for four vehicle lengths? Not a chance.
Areas our team reach around Coleford
Coleford is a rural village, so our team head out to the town and to anywhere by it on the same trips: Penstone, Colebrooke, Knowle, Copplestone and Yeoford.
There are pages for most locations around Devon, and the ones mentioned above are simply the closest neighbours — so yours being missing from that list says nothing whatsoever about whether our technicians come. Call us to enquire instead of assuming, particularly when you're on a border or somewhere a satnav struggles with.
That map shows the area this page includes. Your vehicle doesn't need to come to us. We operate over all of that — roadside, forecourts, driveways, car parks.
Broken down on the roadside around Coleford
Not everyone has a safe place to pull in. If you noticed after setting off and landed along the verge beside Ford Hill, or in a lay-by somewhere with the hazards going, that's a routine call for us rather than an odd one.
Whether you sit by the vehicle or keep away from it rests on if staying there looks sensible. It will often oblige. A diesel running on petrol limps along perfectly willingly, and that's the catch: fire it up to reach somewhere safer and that blend goes further into the fuel system with every mile covered. A technician driving to an inconvenient location is no bother for us, and it is a lot better for your car than driving on.
Run it already? Pull over, and read below
The local M5 is the road that matters now, and it sits under 15 miles from Coleford. A wrongly fuelled diesel will frequently take you onto it and some distance along before anything seems wrong, while the symptoms when they arrive are normally a loss of power, an uneven idle and some smoke rather than a tidy stop.
Come off at the first sensible junction, turn off, and never start the vehicle to reposition. Suppose the worst of it on a long drive. Anything close to the under 15 miles to the closest city, and the petrol has been through the filter, through the pump, through your injectors. Tell us when you phone. What we bring differs.

Coleford is surrounded by nearby places such as Penstone, Colebrooke, and Knowle, and is characterized by its predominantly detached housing.

Our job around Coleford, step by step
- The replies change the work, which is why our technicians ask before giving a price: what got in, how much of that, and if the engine has run.
- Our engineers clear that tank of all the tainted mixture.
- What is remaining in the fuel system shouldn't be what created the issue, so your fuel lines get cleaned and the fuel filter cleared.
- We put clean diesel in and bleed your system.
- It is fired up with new diesel in it, and our engineers confirm that it's running smoothly.
From there, you are ready to set off. Lasting damage is very uncommon when it has been spotted soon, and as everything is done where your car is, it never needs to be taken to a garage.
A distinct problem: AdBlue in a diesel tank in Coleford
Do not start it: that opening step applies whether what got in was AdBlue or petrol. What changes is this fault itself. Petrol thins your diesel and removes the protection your fuel system depends on. Corrosion and build-up are what a diesel tank gets instead, because AdBlue is urea dissolved in water.
AdBlue removal in Coleford has a page of its own with the detail on it, including why it's frequently the more significant of the two. Our engineers cover both.
How much is a petrol-in-diesel drain around Coleford?
One figure would not be honest here, because this is not one job. These are the things that change it:
- This is the key one: whether your motor has been run, or driven.
- How much of the wrong fuel went in, judged against how much your tank takes.
- The sort of liquid in the tank, unleaded or AdBlue.
- Whether our van can sensibly reach your vehicle and work on it, which depends on where your car is.
Tell us the car, the quantity and if it has run, and you'll get a clear answer instead of a range. Vehicle at home, going nowhere, nothing urgent about it — is ideal for that.
Petrol in diesel: frequent queries around Coleford
Can you do a fuel drain at a petrol station around Coleford?
Yes — forecourts are where a big share of this gets done. Tell us which one you're at when you call and we'll tell you if we can work there. With the station's agreement our engineers attend Tesco and the other forecourts locally regularly.
How much petrol is too much for a diesel?
It depends on the proportion rather than the litres, and a lot more on whether the engine has run. Five litres in an almost empty tank is a different case from five in a full one — but either way, the thing that decides how much work is required is whether that mixture has been sucked through the system.
I drove it after putting petrol in my diesel. What next?
Turn off somewhere safe, and keep it that way after you stop. Driving is what shifts the trouble from the tank into the pump and injectors — but it is fixable far more regularly than motorists assume, and the single most valuable thing you can do now is not restart the car.
Is a fuel drain going to void my warranty?
A manufacturer's warranty outlasts a drain then flush done to a good standard, which is no alteration at all. An argument over a warranty is likelier to come from running a diesel on petrol — so leave it turned off.
Can I just add two-stroke oil and drive home?
No. It belongs to a different problem from a separate era, and petrol has thinned something no oil of that kind replaces. Petrol stays in that tank later on, whatever else goes in, and the pump gets no break from it.
Main dealers and petrol in a diesel
There is no need to bring it to a dealership, as our technicians drain and flush the vehicle wherever it is.
You, and the vehicle, still together?
Shut off is how it stays.
Switch it off somewhere sensible and keep it off, if you have already driven it. Cold and still, a motor is in the best place available — and motorists fear this far more than the recovery rate warrants.
