Put Petrol in a Diesel Car in Burghfield Hill? Don't Start It
If you have not started the motor yet, do not. A drain and nothing else is almost always what a vehicle needs while the petrol is still inside that tank and the engine has not run, which is why it's the coming few minutes that count, not how much got in. Petrol in Diesel travels to the vehicle wherever it has stopped in Burghfield Hill or the remainder of Berkshire, on the forecourt, by the roadside or on a driveway, and drains and cleans it there. Call us and then we will tell you what happens next before you attempt anything else.
Now what? Petrol in a diesel, step by step
- Do not crank it. Fired up regardless? Then never trust it. Diesel in a petrol vehicle generally can't run, and so the driver stops and the damage ends with them. Petrol in a diesel? It starts. It idles. It drives off fine, for a few miles. Motorists get that muddled. It's not okay — that fuel system is grinding every mile you do.
- Switching your ignition on commonly primes your system, and priming is what pulls petrol out of the tank and into your pump and injectors. Those are the components diesel keeps greased on its way through, before it ignites. Petrol manages the burning and none of the protecting. Leave your ignition alone.
- Topping up removes nothing. It hands you a bigger tank of the same blend, because a diesel fuel system does not cope with petrol by percentage in the way that guidance implies — so do not put diesel on top to thin it. Type is beside the point too: super unleaded is petrol.
- Stay put if it is safe to. Hazards on, ignition off, keep it. Wherever you have stopped — the verge on Reading Road, anywhere — an odd spot for us trumps a started motor, and nothing is simpler for us to handle than a vehicle that never moved.
- Our van arriving rather than circling hinges on two things: a postcode that starts RG7 3, and whatever is nearest to you with a name on it. Keep both ready before you call.
- Call 0333 366 0103. Let us know what went in, about how many litres, and also whether the engine has fired. These three details determine the whole visit.
Phone before you collect it. Petrol into a diesel Renault Megane this morning, and it outside Mortimer ever since? Then the wait has taken nothing from you: fuel in a tank is dormant, and any harm came on the trip in, when your pump was drawing diesel that petrol had weakened.
Diesel Volkswagen Passat. Some litres of unleaded. Driven a couple of miles. Turned off now, at The Co-operative Food. That's the call our engineers hope for, since the point underneath it is about volume through the pump instead of hours on the clock.
Do not chance it. The drive home from The Six Bells is perfectly possible, which is exactly the issue — a thinned tank doesn't stop a diesel starting or pulling away, it just wears the parts your fuel is supposed to protect. Call us, and let the BMW 3 Series stay where it sits.
Injection pressure is the thing being lost. Petrol weakens diesel, and runnier fuel leaks past the precision components that are supposed to build that pressure, and so the farther a diesel Peugeot 308 drove, the less well it held. Normal on the way out and sluggish on the way back is how that trip to Auclum Green went, then, and that tank is the place to look. Pull in somewhere safe, turn off then phone us.
Three things help when you phone from near Burghfield Common Village Hall: which side the filler is on, whether a technician can park alongside without blocking the road, and if the motor has run since you filled up. On-street is the most common spot our technicians work, and so the location itself is hardly ever the problem — we would far rather deal with a tight parking space than with a motor that has been driven to somewhere more handy. We'll drain your Nissan Qashqai, change the filter where there is a serviceable one, flush your lines and put clean fuel through the whole circuit, because by this point the worst of that is resting in the lines rather than in your tank.
Clearing petrol from your diesel on a forecourt
A big chunk of the work gets completed at a forecourt, as that is where it mostly begins. The drain normally takes place right there. Still on the forecourt at Esso? Given the site's agreement, that's a spot our engineers work, and regularly.
At a garage, this is halted with the motor never started, and nowhere else does that. Everywhere else — a car park, a private drive, a lay-by — the car was switched on and driven to get there, which means fuel was sucked from your tank, through the fuel filter and into your high-pressure pump. That's not a catastrophe, and we can still sort it out where it is. It does mean the fuel lines and the filter need flushing as well as that tank, and that's settled by the few seconds between seeing the till receipt and going for the key.
The staff will usually offer to wheel the car out from the pump so the next motorist can get by. That's worth doing. Four car lengths isn't worth a start.
Do our engineers cover your side of Burghfield Hill?
These same journeys bring us to Burghfield, Goddards Green, Burghfield Common, Trash Green and Whitehouse Green along with Burghfield Hill, which is a residential suburb.
Not on the list? It says nothing. The places above are only the nearest few, and the majority of locations around Berkshire have a page of their own elsewhere on our site. Guessing is the habit to skip, particularly on the boundary or somewhere the satnav gets lost. Contact us to ask.
See the map for the ground shown on this page. Kerbside, forecourt, drive, car park: every bit of it is territory our technicians work on, and none of that requires your vehicle to move to us.
Burghfield Hill: stuck where you stopped
Not everyone gets a sensible spot to stop. A routine call for us instead of a rare one: noticed after setting off, landed on the verge on Hillside or at a lay-by with the hazards on.
Clear of the car if it isn't safe to be there, with it if it is. It will often oblige. A diesel running on petrol limps along quite willingly, and that is the catch: restart the car to get to somewhere better and that mixture goes further into the fuel system with every mile travelled. We'll send our van to a difficult place without any bother, and for the car that is much better than pressing on.
Driven it already? Pull in, then check this
This is where your M4 comes in, under 3 miles from Burghfield Hill. Some distance along, and onto it in the first place: a misfuelled diesel will frequently do both before anything feels wrong. What you get then is seldom a neat stop. Power falls away, your idle goes rough, and there may be some smoke.
The first sensible exit is the one to take. Turn off there, and leave the restarting alone. Long trip? Anything approaching the under 50 miles to the nearest city and you should presume the lot — filter, pump, injectors, all of it arrived at by the petrol. Say that on the phone, as it affects what goes in the van.
Burghfield Hill itself

Burghfield Hill has a population of approximately 1692 residents, living in predominantly detached homes.
What our technicians do when our technicians reach you in Burghfield Hill
- Three things get established before any quote — your fuel that was put in, the quantity, and whether anything has been run since. Each answer alters the work.
- Your tank is drained of it.
- What is left in the system should not be what created the problem, so the fuel lines get purged and the filter cleared.
- New diesel goes in, and then the system gets primed.
- Our engineers start the engine and make sure it runs correctly on fresh diesel.
The car is then ready for you to pull away. All of this is done where the car is, so it never has to go to a garage, and when it has been caught soon, lasting damage is very unusual.
Burghfield Hill AdBlue removal is a different matter
AdBlue instead of petrol? Then the first step is unchanged — the motor remains off — while this issue underneath it's a separate one altogether. The protection a fuel system depends on gets taken away by petrol, which thins the diesel. Corrosion and deposits are what a diesel tank ends up with instead, since AdBlue is urea dissolved in water.
Often the more serious of the two, AdBlue — and the full story lives on its own Burghfield Hill page. Both are ours to handle.
Burghfield Hill prices for a petrol-in-diesel drain
Frankly, no single number fits on a page like this. This job differs. Here is what changes it:
- Whether your motor has been run or driven. This is the big one.
- Wrong fuel in, against what that tank takes — that ratio.
- AdBlue or unleaded, whichever was put in.
- Whether a technician can sensibly get to the vehicle and work on it, which depends on where your vehicle is.
Tell us your car, the quantity and if it has run, and you'll get a straight answer rather than a range. Car at home, going nowhere, nothing urgent about it — is fine for that.
Petrol in diesel questions from Burghfield Hill motorists
Can you do a fuel drain at a petrol station in Burghfield Hill?
A large portion of this work takes place there, so yes. Consent from the site is the condition. Given that, a forecourt like BP is somewhere we're often enough, along with the rest of them locally — so name yours on the phone and you'll hear whether working there is possible.
A couple of litres of petrol in a diesel — too much?
Ratio decides it instead of litres — and more than either, whether the engine has run. Five litres into an almost dry tank isn't five into a full one, no. But both land on the same question in the end: has that mixture been drawn right through, or has it not?
Already driven it with petrol in your diesel? Now what?
Somewhere safe, then stop, then turn off and leave it off. Driving shifts the issue along — out of that tank, into the pump and injectors. Drivers fear it a good deal more than the recovery rate warrants, mind. The one really useful thing left to you isn't restarting it.
My warranty — does a fuel drain void it?
No. Carried out properly, emptying and rinsing is no change at all, and the warranty from your manufacturer is untouched by it. What's likelier to start a dispute is a diesel that has been run on petrol. One more reason for the engine to stay off.
Could I put some two-stroke in and just drive?
What petrol has weakened is not replaced by two-stroke oil, which is an old fix for a separate problem. So no. The pump still has to cope with it, because the tank still has petrol in it later on.
Main dealers and petrol in a diesel
You do not need one. The car is drained and flushed wherever it is, with no need to bring it to a franchised dealer.
Waiting next to it?
Shut off is the way the car remains.
If you have already driven it, pull in somewhere safe, turn it off and leave it off. Cold, still, going nowhere: that's the best position to be in. Drivers fear this far more than they need to.
