Petrol in a Diesel Car in Somerdale
If you have not started your engine yet, do not. A fuel drain and nothing more is almost always what a vehicle needs while the fuel is still sitting in your tank and the motor has not yet been started, which is why it is the following few minutes that count, not how much was put in. Petrol in Diesel comes to the car wherever it has stopped in Somerdale or the rest of Somerset, on the forecourt, at the roadside or on a drive, and drains and flushes it there. A single call to us will be plenty: we can show you what follows next. Do this first.
What next? Petrol in a diesel, in turn
- Give a petrol motor diesel and it will usually refuse to run at all, so the motorist stops there and so does the damage. Give a diesel petrol and the engine starts, it idles, it moves off — fine for a few miles. Most people have that reversed, which is the part they get wrong about petrol in a diesel in particular. So do not start the vehicle. And if started, don't depend on it: that fuel system is wearing while you drive.
- Two jobs, diesel: it burns, and on the way through it keeps that injection pump and injectors lubricated. Petrol only manages the one. Which is why the car's ignition is left off as well — turn it on and you commonly prime that system, and that is petrol exiting the tank for precisely those components.
- Don't water down it. Diesel put on top clears nothing, so all you have is more of what was already there, since percentage isn't how a diesel fuel system tolerates petrol. Super unleaded? Simply petrol. The octane makes no difference.
- A motor that has never moved is the easiest one to deal with, so remain where you are if you reasonably can. Pulled up on the verge on Chandos Road? Hazards on, and leave the vehicle there. A difficult spot works for us better than a started diesel.
- Before you dial, get your position. Anything closest to you with a name on it, plus a postcode starting BS31 2 — that is what decides whether the van turns up or circles.
- What went in, roughly how much, and also if the motor has run — these three facts determine the whole job. Dial 0333 366 0103 then tell us.
Quarter past eight, a fast top-up on the trip in, and it dawns on you at about eleven — by that point your diesel Volkswagen Golf has been left at Keynsham for three hours. Call us then keep the vehicle precisely where it stands. The drive in is the bit that is key here, because diesel performs two jobs on its way through the engine: it burns, and before it ignites it protects the high-pressure fuel pump and the injectors. Petrol manages the first and not the second. So those few miles were done with the pump working on a fuel that had lost much of the protection it is made for — which is why the thing our technicians ask is how many miles you drove, not how long your car has been stood.
A diesel pump delivers fuel to demand, and a frantic morning run demands plenty — so three miles in the BMW 3 Series seems like nothing and is not. Twenty to nine by Somerdale Educate Together Primary Academy, running late, a receipt in your hand reading unleaded: hazards on, engine off, phone.
Leave it there overnight. Phone in the morning. Nothing about a diesel Nissan Qashqai sitting in the car park outside The Old Bank degrades while it stands, tank of petrol or not, and the job stays a simple one right up till the moment it gets driven home. The query our engineers bring is about that run there: a cold engine over a short hop is where petrol combusts least well, and whatever fails to burn can work its way past the rings into the sump.
Draining your Ford Focus, changing the filter where there is a workable one, rinsing the fuel lines, putting clean fuel through the full system: that is this job, and it is shaped by the worst of that resting in the lines instead of in the tank by this point. Three things help when you phone from near St Dunstan's Catholic Church — which side the filler is on, whether a technician can park next to without blocking the road, and if your engine has run since you filled up. On-street is the commonest location our technicians work, and so the spot itself is hardly ever the issue. A narrow parking space beats a car driven somewhere more convenient.
A vehicle you picked up two days ago gets driven further before anybody notices anything, which is the hire and courtesy issue in one sentence — and how far it went is what determines the volume of petrol getting to the fuel injectors. Nothing slapdash about the mistake itself: a current diesel filler neck accepts the slimmer petrol nozzle with practically no resistance, and so strange spots see most of these. Phone us from wherever you are, close to Keynsham Roman Villa or not, and we will get to the Mercedes C-Class.
Can petrol be taken from a diesel at the forecourt?
Most of this work starts at a pump, which means a large part of that gets done at one. If you are still at the forecourt at Esso, that's normally where this drain takes place — we operate on petrol station forecourts all the time, with the owner's agreement.
Before the motor has started — the forecourt is the single spot the mistake is halted. Anywhere else — a car park, a drive, a lay-by — your car was switched on and moved to get there, which means fuel was pulled from the tank, through the fuel filter and into the high-pressure fuel pump. That is not a disaster, and we can still sort it out where it sits. It does mean the fuel lines and the fuel filter need cleaning as well as the tank, and that's determined by the few seconds between reading your receipt and going for the key.
The attendants will usually offer to move the vehicle out from the petrol pump so the next driver can get by. That's worth doing. Moving the car four bays doesn't merit firing the motor.
Areas our vans reach near Somerdale
Keynsham, Stockwood Vale, Hanham Green, Willsbridge, Hicks Gate — all of those on our trips that carry us across to Somerdale too, a residential suburb.
We still come. The names above are merely the immediate neighbours, and a page is there for most towns in Somerset, and so an absence from the list is not an absence from our coverage. Ring us and ask instead of presuming — county lines above all, and wherever a satnav might misread.
See our map for the area included on this page. All of that is territory our engineers cover: a roadside, a forecourt, a private drive, a car park. You do not move the car anywhere.
Roadside breakdowns around Somerdale
Not everyone has a chance to pull in somewhere safe. If you worked it out after setting off and ended up on the verge on Dryleaze, or in a lay-by somewhere with your hazards going, that's a common call for us and not an odd one.
Out of your car when it's not sensible to sit in it, by it if it is. Every mile a diesel obliges you for on petrol drags the blend further into the system — and oblige it frequently will, which is why your engine doesn't get restarted to limp somewhere better. We'll bring the van to an awkward location without any trouble, and for the car that's a lot better than driving on.
Petrol in a diesel, but the motor has travelled
This is where your M32 comes into it — under 5 miles away from Somerdale. A misfuelled diesel will usually get you onto it and some distance along before anything seems wrong, and the symptoms when they appear are generally a loss of power, a rough idle and some smoke instead of a clean stop.
Take the next junction that's safe, stop there, and never restart it to move it. Suppose the worst of it on a long trip. Anything near the under 10 miles to the closest city, and the contamination has been through the fuel filter, through your pump, through your injectors. Say so when you ring. What our engineers bring differs.

What our engineers do when we get to you around Somerdale
- Our technicians ask first, quote after. What got in? How much? Has your engine run? Those answers change what the work actually is.
- Our technicians drain your tank of all the contaminated fuel.
- We purge the fuel lines and clean the filter, and so what's left in the system is not what caused the problem.
- Our engineers pour new diesel in and prime your system.
- It is run with fresh diesel in it, and our technicians make sure that it is running correctly.
From there, you are ready to drive away. There is no need for a workshop at any stage, as the work is all done where your car is, and when it's spotted quickly, lasting damage is very rare.
A different matter: AdBlue in a diesel tank around Somerdale
The issue isn't the same, though the first step is — don't fire it up — if what was put in was AdBlue instead of petrol. The protection a fuel system relies on gets taken away by petrol, which weakens the diesel. Rust and residue are what a diesel tank gets instead, since AdBlue is urea dissolved in water.
We deal with both, and AdBlue removal in Somerdale has its own page with the detail — including why it is frequently the more serious of the two.
How much is a petrol-in-diesel fuel drain around Somerdale?
We cannot put one number on this page frankly, because the job isn't one job. What changes it:
- Started? Driven? Either answer matters more than anything else on this list.
- The tank's capacity, set against how much of the wrong fuel went into it.
- Whether it is unleaded or AdBlue.
- Where your car is, and if a van can sensibly reach and work on it.
Tell us the car, the quantity and whether it has run, and you'll get a firm answer rather than a range. For your car at home that's going nowhere and isn't time-critical, works too.
Questions we get about petrol in diesel around Somerdale
I'm on a forecourt in Somerdale. Can you drain the vehicle here?
Plenty of what our technicians do happens nowhere else. So yes. We work at BP and the other forecourts nearby regularly, with the station's permission — tell us which one you are at when you call and we'll tell you whether our engineers can work there.
How much petrol in a diesel is too much?
Ratio decides it instead of litres — and more than either, whether your engine has run. Five litres in a nearly empty tank is a different situation from five in a full one — but either way, the thing that decides how much work is needed is if that mix has been sucked through the system.
Already driven it with petrol in your diesel? What then?
Pull over somewhere safe, turn off, then leave it off. It is salvageable a lot more commonly than drivers expect, even though driving is what shifts the trouble from the tank into the pump and injectors — and the single most useful thing you can do now is not restart it.
Is a fuel drain going to void my warranty?
It is not a modification, so a drain then flush carried out properly does not void a manufacturer's warranty. Another good reason to leave it turned off: running a diesel on petrol is the thing more likely to cause a dispute with one.
Could I put some two-stroke in and just drive?
Two-stroke oil solves a different issue, and an old one at that. Nothing it does puts back what petrol weakened. No. Your tank still has petrol in it later on, and the pump still has to put up with it.
A main dealer for petrol in a diesel — needed?
There's no need to bring it to a franchised dealer, because our engineers drain and flush your car wherever it is.
Standing next to it?
Switched off is the way it remains.
Turn it off somewhere sensible and keep it off, if you have already driven it. A still, cold vehicle is the best place to be in, and this is recoverable from far more frequently than people fear.
