Dowlish Ford: Put Petrol in a Diesel Car?
If you have not turned on your engine as yet, don't. A drain and nothing more is almost always what a car requires while the petrol is still in your tank and your engine has not yet run, which is why it is the coming few minutes that count, not how much was put in. Petrol in Diesel travels to the vehicle wherever it has come to rest in Dowlish Ford or the remainder of Somerset, on the forecourt, at the roadside or on a private drive, and drains and cleans it there. Phone before anything else happens, so you will see what follows after that.
What next? Petrol in a diesel, in order
- Don't fire it up. Started all the same? Then don't rely on it. Diesel in a petrol motor usually can't run, and so the driver stops and the harm ends with them. Petrol in a diesel? It starts. It idles. It pulls away fine, for a couple of miles. Most people get that backwards. It is not okay — that fuel system is grinding every mile you do.
- Switching your ignition on often primes that system, and priming is what moves petrol out of the tank then into the pump and injectors. Those are the components diesel keeps oiled on its way through, before it ignites. Petrol manages the burning and none of the oiling. Leave the car's ignition be.
- Do not add diesel on top to water down it. A diesel fuel system doesn't tolerate petrol by percentage as that advice presumes, and topping up gets rid of nothing — it only gives you a fuller tank of the same mixture. The type makes no difference either: super unleaded is simply petrol.
- A motor that hasn't moved is the quickest one to deal with, and so stay where you are if you reasonably can. Stopped on the verge on Moolham Lane? Hazards on, then keep the car there. A tricky location works for us better than a started motor.
- Check where you are before ringing. A postcode that starts TA19 0, and the name of whatever is nearest to you. Otherwise our van circles instead of turning up.
- Three details shape the entire visit: the liquid you tipped in, the approximate quantity of it, plus if it has been running since. Our line is 0333 366 0103.
Don't run it home. The commute has already forced a real quantity of petrol-thinned diesel through your high-pressure pump of that Volkswagen Golf, and the journey back would about double it for no gain at all. Ring us from the platform if that is simpler. Our technicians don't need you standing over the car at Crewkerne while our technicians get on, and our team would very much rather hear from you tonight than discover on Monday.
Straightforward, these ones, and the reason is the distance: a mile at light throttle draws little fuel. Petrol into a diesel Peugeot 308 somewhere in Dowlish Ford, a boot packed with shopping, and you stranded at Tesco — phone. Exiting the space isn't worth another start. The tank gets drained where it waits, your fuel lines purged, fresh diesel in, and you drive home.
Someone will tell you to shift the car out of the gateway and sort it out later. Do not. A wrongly fuelled diesel Nissan Qashqai on the zig-zags outside Herne View Church of England Primary is an inconvenience; the same motor fired up three more times to be polite is a fuel system rather than a tank. Each restart primes the fuel lines and pulls more petrol through your filter then into the pump. Leave it, let them complain, and phone us.
Simple job, this one — till somebody drives it home. A diesel Mercedes C-Class left by The Royal Oak with petrol in that tank loses nothing by sitting there overnight, so park it and phone us once it's light. Expect a question about the run there, though. Short and cold is exactly where petrol battles to burn, and what will not burn can work past the rings and into the sump.
A throttle gone soft, white smoke, an uneven idle, rattling: that's a misfilled diesel BMW 5 Series telling you what is wrong. Never start it to find a better spot — turn off where you have stopped, close to Church of St Mary or anywhere else.
Draining petrol from a diesel on a forecourt
Much of the work starts at a pump, meaning a big share of it ends up finished at one. Still at Tesco? Then that is usually where it takes place. Garage forecourts are everyday for us, with the agreement of the owner.
A filling station is the single spot this is stopped before your engine has started. Anywhere else — a car park, a driveway, a lay-by — the car was started and driven to get there, which means fuel was sucked from the tank, through the filter and into your high-pressure pump. That's not a catastrophe, and we can still deal with it where it is. It does mean the fuel lines and your filter need rinsing as well as the tank, and that's settled by the few seconds between seeing the till receipt and reaching for your key.
The staff will generally happily roll the vehicle clear of the petrol pump so the next driver can get through. That's worth doing. Starting the car just to shift four car lengths is not.
Service near Dowlish Ford
The same journeys bring us to Moolham, Ilminster, Sea, Townsend and Knott Oak besides Dowlish Ford, which is a village.
Not on this list? That tells you nothing. The places above are just the closest few, and nearly all places across Somerset have a page of their own somewhere on our site. Contact us to check rather than guessing — county lines especially, and anywhere the satnav can struggle with.
See our map for the ground included on this page. Kerbside, forecourt, private drive, car park: all of it is ground our technicians work on, and none of it needs the vehicle to come to us.
Roadside breakdowns across Dowlish Ford
Not everybody has a chance to pull in somewhere safe. A normal call for us rather than an odd one: noticed after setting off, landed along the verge of Long Close or at a lay-by with the hazards on.
Okay there? Sit with it. Not fine? Move out and clear of it. It will frequently oblige. A diesel running on petrol limps along very willingly, and that is the trouble: start it up to get to somewhere handier and that mixture goes further into the fuel system with every mile driven. We'll send our van to a tricky spot without any bother, and for the car that is much better than carrying on.
Driven it already? Pull in, and check below
under 10 miles out of Dowlish Ford, the M5 is what matters here. A misfilled diesel will usually get you onto it and some way along before anything feels wrong, and the symptoms when they come are typically a loss of power, a rough idle and smoke rather than a clean stop.
The next safe exit is the one to take. Turn off there, and leave the restarting alone. Long run? Anything approaching the under 25 miles to the nearest city and you should presume the lot — filter, pump, injectors, all of that reached by the contamination. Say that on the call, because it alters what goes in our van.
About Dowlish Ford

Dowlish Ford lies approximately 23 miles from Wells and 127 miles from London, making it a rural community with some commuter links. Dowlish Ford has a mix of housing types, but semi-detached homes are particularly prevalent in the area. Dowlish Ford is surrounded by other small villages, including Moolham and Ilminster, and is near the Somerset coast.
Once our technicians arrive with you in Dowlish Ford: what we do
- The replies alter the work, which is why our engineers ask before pricing: what was put in, how much of it, and whether your motor has run.
- The tainted fuel comes out of that tank.
- What is left in the fuel system shouldn't be what started the problem, and so the lines get rinsed and your filter cleared.
- The system gets bled, on fresh diesel.
- We fire it up and make sure it runs properly on clean diesel.
At that point it's ready to set off. Our technicians do everything wherever the car has come to a stop, which means it never has to be taken to a garage, and when it has been caught early, it's very rare for there to be lasting damage.
Dowlish Ford AdBlue removal is a separate job
Do not start it: that opening rule applies whether what got in was AdBlue or petrol. What differs is this fault itself. Petrol weakens the diesel and removes the lubrication your fuel system depends on. Corrosion and residue are what a diesel tank ends up with instead, as AdBlue is urea dissolved in water.
We cover both, and AdBlue removal in Dowlish Ford has its own page with the detail — including why it is frequently the more significant of the two.
What a petrol-in-diesel drain will cost in Dowlish Ford
Truthfully, no single figure fits on a page like this. The job varies. Here is what moves it:
- This is the main one: whether the engine has been started, or driven.
- Wrong fuel in, against what that tank takes — that ratio.
- Which got in: petrol or AdBlue.
- Where the vehicle is, and if our van can sensibly reach and work on it.
The vehicle, the amount, whether it has run — give us those and the answer comes back straight rather than as a range. Motor at home, going nowhere, nothing time-critical about it — is fine for that.
Questions we hear about petrol in diesel in Dowlish Ford
I'm on a forecourt around Dowlish Ford. Can you drain the vehicle here?
A good portion of this work gets done there, so yes. Tell us which one you're at when you ring and we will tell you whether our technicians can work there. With the site's consent our technicians attend Texaco and the other forecourts around town all the time.
A couple of litres of petrol in a diesel — too much?
Litres aren't the measure. Proportion is, and far more than either, it counts if anything has been run. What settles how much work is required is if that mixture has been pulled through the system — since though five litres in a nearly empty tank is a separate matter from five in a full one, either way that is the question.
I put petrol in my diesel and drove the car. Now what?
Stop safely. Off. Nothing after that. Driving shifts the trouble along — out of that tank, into your pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one truly valuable thing left to you is not restarting it.
My warranty — does a fuel drain void it?
It isn't an alteration, so a drain then flush carried out correctly doesn't void a manufacturer's warranty. Another reason to leave it switched off: running a diesel on petrol is the thing more likely to cause a dispute with one.
Can I just add two-stroke oil and drive home?
No. Two-stroke oil is an old workaround for a distinct problem and it does not restore what petrol has thinned. The tank still has petrol in it later on, and your pump still has to live with it.
A main dealer for petrol in a diesel — essential?
Not at all. Our engineers drain and flush the vehicle wherever it is, so there's no need to take it to a dealership.
You, and your vehicle, still together?
Never switch the engine on again.
If you have already driven the vehicle, pull over somewhere sensible, turn it off then leave it off. A stationary, cold car is the best place to be in, and this is recoverable from a lot more regularly than drivers fear.
