Put Petrol in a Diesel Car in Lydford Fair Place? Don't Start It
If you have not fired up your engine yet, do not. A fuel drain and nothing else is almost always what a car requires while the fuel is still inside that tank and the engine has not yet been started, which is why it's the following few minutes that matter, not how much went in. Petrol in Diesel comes to your car wherever it has ended up in Lydford Fair Place or the rest of Somerset, on the forecourt, by the roadside or on a private drive, and drains and cleans it there. Just one call to us is sufficient: our team can tell you what follows after this. Make it straight away.
Petrol in a diesel: what to do now
- Never fire it up. Fired up all the same? Then never believe it. Diesel in a petrol motor generally will not run, so the person stops and the harm stops with them. Petrol in a diesel? It starts. It idles. It drives off normally, for a few miles. Motorists get that muddled. It isn't okay — your fuel system is wearing every mile you cover.
- Switching the ignition on commonly primes your system, and priming is what carries petrol out of that tank and into your pump and injectors. Those are the parts diesel keeps greased on its way through, before it ignites. Petrol manages the burning and none of the oiling. Leave the car's ignition be.
- That advice assumes a diesel fuel system tolerates petrol by percentage. It doesn't. Pour diesel on top and nothing at all is cleared; what you get is a fuller tank of the same blend. And no, the octane makes no difference — super unleaded is simply petrol.
- A motor that has never shifted is the simplest one to sort, so wait where you are if you reasonably can. Stopped on the verge on Fair Place? Hazards on, then leave the vehicle there. An odd place suits us better than a started engine.
- Before you ring, gather your whereabouts. Anything next to you with a sign on it, plus a postcode that starts TA11 7 — that's what decides whether our van arrives or circles.
- What went in, roughly how many litres, plus if your car has run — the three facts settle the whole visit. Call 0333 366 0103 then tell us.
The run in is what pushed diluted diesel through the pump. Standing still has drawn nothing. Petrol in a diesel Volkswagen Golf, parked at Castle Cary all day, sits dormant in that tank whilst it waits. Phone us first — before the keys turn.
How much fuel the pump has drawn is what we're truly asking — not how long ago any of that was. So the call we want runs like this: diesel Renault Megane, some litres of unleaded, a couple of miles driven, now shut off outside Co-op Food.
None of it is your engine failing. That is the bit worth hearing, and it's why the ordinary Wheathill Golf Club call ends better than it sounds: a diesel Audi A4 drives out there without fuss, comes back with the power gone, the idle rough and possibly a little smoke, and the cause is the fuel no longer acting like diesel. Diesel has to be heavy enough to seal the tightly fitted parts it runs through; petrol thins it; and a diesel injection system is hydraulic as much as chemical, needing your fuel to hold pressure and not only to burn. So pressure that should build and stay built bleeds past tolerances, delivery turns up poorer and later and less even than engineered, and all of that stops once the fuel is put right.
Most of these happen somewhere new, and the cause is mechanical instead of slapdash — almost no resistance meets a smaller petrol nozzle entering a current diesel filler neck. Two days into a diesel Mercedes C-Class, a fill-up by Church (Remains of) that you did not think about? Ring us from where you are. Courtesy and hire cars go further before anyone notices it, and the further they go, the more petrol ends up at your injectors.
It got a few streets and stopped. The throttle went limp, the idle turned lumpy, and your diesel Vauxhall Astra is now sitting near St Mary. That deadness is your fuel failing to build pressure properly not the engine giving up — and as there's no dashboard light for it, vehicles in that position typically get driven again before somebody rings. Please don't. Turn it off then ring us.
Draining petrol from a diesel at the forecourt
Much of this work begins at the pump, meaning a big chunk of it is done at one. Still at Shell? Then that's normally where it happens. Petrol station forecourts are routine for us, with the agreement of the station.
At the forecourt, the mistake gets stopped with the engine never started, and nowhere else does it. Our technicians can still sort it out where it stands, even away from the pumps. In a car park, on a private drive or in a lay-by, the car has been started and driven there, and that drew fuel through your filter and into the high-pressure fuel pump, right from your tank. None of that is a calamity, but the flush then has to go past the tank to your lines and the fuel filter, and the few seconds between reading the till receipt and reaching for the keys are what determine that.
Attendants will generally pitch in pushing it away from the pump, which lets the next driver get past. Welcome the offer. Starting the car just to roll four vehicle lengths is not.
Lydford Fair Place and the towns beside it
The same rounds carry us to West Lydford, East Lydford, Lydford-on-Fosse, Southwood and Catsham as well as Lydford Fair Place, which is a rural hamlet.
If yours isn't on that list it doesn't mean we never come — there are pages for the majority of places across Somerset, and the ones named above are simply the immediate neighbours. Call us and ask rather than guessing, above all where you're on the border or somewhere a satnav struggles with.
That map outlines the area this page covers. We work at the roadside, at forecourts, on driveways and in car parks throughout all of it, and your car doesn't need to come to us.
Roadside call-outs around Lydford Fair Place
Not everybody has a safe spot to pull in. Hazards going in a lay-by somewhere, or stopped on the verge beside High Street since you worked it out after setting off — our engineers take that call often enough that it is the ordinary kind.
Whether you sit beside the vehicle or move away from it hangs on whether staying there is safe. Don't restart it to get to a nicer place. It will go — a diesel on petrol usually obliges — and each mile of obliging draws the blend deeper into the system. We will bring our van to a difficult place without any trouble, and for the car that is a lot better than carrying on.
Some miles on petrol in a diesel: now what?
under 25 miles out of Lydford Fair Place, your M5 is what counts here. Lost power, an uneven idle, some smoke: those are the signs when they appear, rather than a neat stop — and a misfuelled diesel will usually get you onto it and some distance along before anything feels wrong at all.
Take the first exit that's safe, stop there, and never start it to reposition. Presume the worst of that on a long trip. Anything close to the under 10 miles to the closest city, and the contamination has been through the filter, through your pump, through the fuel injectors. Say so when you call. What our engineers bring alters.

Our job around Lydford Fair Place, step by step
- The answers change the work, which is why our technicians ask before pricing: what was put in, how much of it, and whether the motor has run.
- We clear that tank of the contaminated mixture.
- What is left in your system should not be what caused the trouble, so the fuel lines get purged and the fuel filter cleaned.
- Our engineers pour fresh diesel in and prime the fuel system.
- We fire it up and check it runs properly on fresh diesel.
After that it's ready to set off. Our technicians do everything wherever the vehicle has ended up, which means it never needs to go to a garage, and if it has been caught soon, it is very uncommon for there to be permanent damage.
AdBlue in your diesel tank by mistake, in Lydford Fair Place?
AdBlue rather than petrol? Then the opening rule is unchanged — the motor remains off — while this fault under it's a different one altogether. Petrol does two things to diesel: thins it, and takes away the protection the system relies on. AdBlue is urea in water, and in a diesel tank it causes corrosion and residue instead.
We cover both, and AdBlue removal around Lydford Fair Place has its own page with the details — including why it's often the more significant of the two.
What a petrol-in-diesel drain costs in Lydford Fair Place
Honestly, no single number belongs on a page like this. The job changes. Here is what varies it:
- This is the main one: whether your engine has been started, or driven.
- The tank's capacity, set against how much of the wrong fuel got into it.
- Whether it is unleaded or AdBlue.
- Whether a van can sensibly get to the car and work on it, which depends on where your car is.
Tell us what the vehicle is, how much got in, and if the engine has run. A clear answer comes back, not a range. Not pressing, with the car at home and going nowhere? Then works.
Petrol in diesel: common questions around Lydford Fair Place
Can you do a fuel drain at a petrol station in Lydford Fair Place?
Yes, and it is where a fair portion of this work gets done. Tell us which one you're at when you ring and we'll tell you whether our engineers can work there. With the station's permission our engineers attend another forecourt nearby and the other forecourts locally all the time.
Is there a safe quantity of petrol in a diesel?
It hinges on the ratio rather than the litres, and a lot more on whether your motor has run. A nearly empty tank with five litres in it, against a full one with the same five: distinct situations, definitely. Either way, the work required comes down to one thing, which is whether the fuel system has had that blend sucked through it.
Petrol in my diesel, and I have driven the car
Stop sensibly. Off. Nothing after that. Driving is what moves the trouble from your tank into the pump and injectors — but it is salvageable far more often than people fear, and the single most helpful thing you can do now is not restart the vehicle.
Is a fuel drain going to void my warranty?
A drain and flush carried out correctly isn't a modification and doesn't cancel a manufacturer's warranty. Another reason to leave it turned off: running a diesel on petrol is the thing likelier to cause a disagreement with one.
Can I just add two-stroke oil and drive home?
No. It belongs to a different issue from a different era, and petrol has diluted something no oil of that kind restores. Afterwards? Still petrol in your tank, and a pump that has to cope with the stuff.
Does petrol in a diesel have to go to a main dealer?
Wherever your car is, we drain and flush it there, so a visit to the main dealer doesn't come into it.
You, and the car, still together?
The motor stays off.
If you have already driven the vehicle, pull over somewhere sensible, turn it off and keep it off. A stationary, cold vehicle is the best place to be in, and this is recoverable from a lot more often than people fear.
