New Town: Put Petrol in a Diesel Car?
With that tank still holding the fuel and your engine not yet started, almost every job requires only a drain, so keep the engine off. That result is decided in the minutes immediately after the fill-up, and not by the amount that went in. All over New Town and the remainder of Berkshire, Petrol in Diesel drains your car and cleans it where it is, whether by a roadside, on a private drive or at a forecourt. Call us and our engineers shall tell you what comes next before you attempt any more.
Petrol in a diesel: what to try now
- Never start the car — and never rely on it when it starts. Here is the bit motorists get wrong about petrol in a diesel specifically. A petrol engine given diesel typically just can't run, and so the person stops and the wear ends with them. A diesel filled with petrol normally starts, idles and drives away just fine for several miles. It is not okay. It's wearing out the fuel system as you drive.
- Switching the ignition on frequently primes the system, and priming is what carries petrol out of the tank and into the pump and injectors. Those are the parts diesel keeps greased on its way through, before it combusts. Petrol handles the burning and none of the protecting. Leave the ignition be.
- That advice presumes a diesel fuel system copes with petrol by percentage. It does not. Add diesel on top and nothing at all is removed; what you end with is a fuller tank of the same mixture. And no, the grade makes no difference — super unleaded is still petrol.
- Remain where you are if you sensibly can. A car that hasn't shifted is the quickest one to deal with, and our team would sooner come to an odd location than have it started. If you're stopped on the verge on Cholmeley Road, switch the hazards on and keep the vehicle there.
- Find out where you are before phoning. A postcode beginning RG1 3, and the name of whatever is next to you. Otherwise the technician circles rather than showing up.
- Phone 0333 366 0103. Say what got in, roughly how many litres, and if your car has started. These three facts decide the whole visit.
Phone before you fetch the vehicle. Petrol into a diesel Volkswagen Golf this morning, and it at Reading ever since? Then the day has taken nothing from you: fuel sitting in a tank is dormant, and any wear was done on the trip in, when the pump was taking diesel that petrol had diluted.
If you have put petrol in your diesel Skoda Octavia around New Town and you are now sat outside Tesco Extra with a boot packed with shopping, phone us. Do not start it a second time to leave the bay. Our technicians will come out to you, empty your tank, clean those fuel lines then put fresh diesel in so you can get home. A mile or so at light throttle uses very little diesel, so these are usually the simple cases.
You drive off at the end, once our engineers have fired it up and checked it runs correctly on fresh diesel, with the system primed. Before that, in the car park outside The Fishermans Cottage, the tainted fuel comes out of the tank, the fuel lines get cleaned and the filter comes off where your Dacia Duster has a replaceable one. Everything begins with three questions when our engineers get to the vehicle: what was put in, how much of it, and whether it has been fired up since.
Nothing is getting worse whilst it sits. Whatever your diesel Mercedes E-Class did on the way to Coal Woodland, it is doing none of that now: the pump is not turning. So take your time — but do not drive the car home to buy yourself any.
Three things help when you phone from near Sun Street Community Centre: which side the filler is on, whether a van can stand beside without blocking the road, and if the engine has run since you filled up. On-street is the usual place our technicians work, so the place itself is hardly ever the trouble — we'd far rather deal with a narrow parking spot than with a motor that has been driven to somewhere more convenient. We will drain your BMW 5 Series, change your filter where there's a usable one, flush your lines and put clean fuel through the entire system, since by this point the worst of that is sitting in your lines instead of in that tank.
Forecourt draining for petrol in a diesel
Forecourts are where the job usually kicks off, and where a big part of that closes. The drain usually happens right there. Still on the forecourt at Tesco? Given the site's consent, that's somewhere our engineers work, and often.
Before the engine has fired — a garage is the single setting the mistake gets halted. Our technicians can still put it right where it sits, even away from the pumps. In a car park, on a private drive or in a lay-by, the vehicle has been started and driven there, and that pulled fuel through the filter then into your high-pressure pump, all the way from that tank. None of that is a catastrophe, although the flush then has to reach past the tank to the lines and the fuel filter, and the few seconds between reading the till receipt and going for the key are what determine that.
The attendants will normally help you push the vehicle away from the petrol pump so the next customer can get by. That is worth doing. Four car lengths is not worth a restart.
New Town plus the villages near it
New Town is a residential suburb, and our vans go out to the town and to the places by it on the same runs: Whiteknights, Lower Caversham, The Mount, Reading and Caversham.
If yours is not on this list it doesn't mean we don't come — there are separate pages for most locations around Berkshire, and the ones mentioned above are simply the nearest neighbours. Call us and ask rather than guessing, above all if you are on a boundary or somewhere the satnav misreads.
Use this map for the ground included on this page. Your car doesn't need to travel to us. We operate throughout every bit of that — kerbside, forecourts, driveways, car parks.
Roadside call-outs in New Town
Not everyone gets a chance to stop somewhere safe. Hazards on in a lay-by somewhere, or pulled onto the verge on School Terrace since you noticed after setting off — our engineers take that call often enough that it's the usual kind.
Okay right there? Sit beside it. Not okay? Step out and clear of it. Do not fire it up to get to a safer location. It will go — a diesel on petrol usually obliges — and each mile of obliging pulls the blend deeper into the fuel system. However tricky the spot, it is no problem for us to get to it, and that's much better for the car than driving on.
Run it already? Stop, then check below
under 3 miles from New Town, your A329(M) is what matters here. It will usually get you onto it, and some way along, before you notice a thing. Then it's smoke, a lumpy idle and power ebbing away — not a clean stop. Misfilled diesels rarely give you one of those.
The next safe exit is the one to take. Switch off there, and leave the restarting alone. Long run? Anything approaching the under 25 miles to the closest city and you should assume the lot — filter, pump, injectors, all of it reached by the petrol. Say that on the call, since it affects what goes in the van.
New Town itself
New Town is a suburban area in Berkshire, situated on the lakeside at an elevation of 43 metres, with nearby places including Whiteknights and Lower Caversham. New Town has a mix of housing types, but is predominantly characterised by terraced homes. New Town is located near The Mount and is within commuting distance of Oxford, which is 24.3 miles away. New Town is also relatively close to London, at a distance of 35.5 miles.
What follows when our engineers arrive with you around New Town
- The answers alter the work, which is why our engineers ask before giving a price: what went in, how much of that, and whether the engine has run.
- The tainted fuel comes from the tank.
- What is remaining in your system shouldn't be what created the issue, and so your fuel lines get flushed and your filter cleared.
- The fuel system gets bled, on fresh diesel.
- When it is started, our engineers check it runs properly on new diesel.
Then it's ready to drive away. Long-term damage is very rare when it has been spotted quickly, and since everything is done where your car is, it never needs to be taken to a garage.
New Town AdBlue removal is a distinct matter
If what got in was AdBlue instead of petrol, the first rule is unchanged — never crank it — yet the fault isn't. Diluted diesel, and no protection left for your fuel system that relies on it. That's petrol. AdBlue? Urea dissolved in water. Put that in with the diesel and you get corrosion instead, plus build-up.
AdBlue removal around New Town has a page of its own with the details on it, including why it's frequently the more serious of the two. We handle both.
How much is a petrol-in-diesel fuel drain around New Town?
Honestly, no single figure belongs on a page like this. The job varies. Here's what moves it:
- This is the key one: whether your motor has been started, or driven.
- How much of the wrong fuel got in, measured against how much your tank can hold.
- Whether it is unleaded or AdBlue.
- Whether our van can sensibly get to your car and work on it, which rests on where the vehicle is.
Tell us the vehicle, the amount and whether it has run, and you'll get a clear answer rather than a range. Not pressing, with the vehicle at home and going nowhere? Then does the job.
Petrol in diesel queries from New Town motorists
At a petrol station in New Town, can you do a fuel drain there?
Yes, and it's where a good part of this work takes place. Often, provided the site agrees: BP, plus every other forecourt nearby. Say on the phone where exactly you have stopped. Whether our engineers can work in that place is something our engineers answer straight away.
A couple of litres of petrol in a diesel — too much?
Litres are not the measure. Proportion is, and much more than either, it counts if anything has been run. What determines how much work is needed is if that mix has been drawn through your fuel system — because although five litres in a nearly empty tank is a distinct case from five in a full one, either way that's the question.
I put petrol in my diesel and drove the vehicle. Now what?
Stop somewhere safe, switch off, and keep the car off. Not restarting it is the single most useful thing available to you now. Driving does shift the problem out of your tank then into your pump and injectors, yes, and it remains recoverable much more regularly than people fear.
My warranty — does a fuel drain void it?
A manufacturer's warranty survives a drain then flush done to a correct standard, which is no alteration at all. Running a diesel on petrol is the thing more likely to cause a dispute with one, which is another reason to leave it switched off.
Adding two-stroke oil, then driving home
No. Two-stroke oil is an old fix for a separate issue and it does not replace what petrol has weakened. Later on? Still petrol in the tank, and a pump that has to cope with the stuff.
Do I need a main dealer for petrol in a diesel?
Wherever your car is, our engineers drain and clean it there, so a trip to the main dealer does not come into it.
Standing next to it?
Shut off is the way the car remains.
Already driven it? Then stop somewhere safe, turn off, and let it stay that way. Cold, parked, going nowhere: that's the best position to be in. People fear this far more than they need to.
