Put Petrol in a Diesel Car in Barbourne? Don't Start It
Petrol in Diesel drains and flushes misfuelled vehicles where they stand, on the forecourt, by the roadside or on a driveway, all over Barbourne and the rest of Worcestershire. The very first thing to do is not to start the motor. When your engine has not run and the petrol is still in the tank, a fuel drain is nearly always all it requires, and the following few minutes decide that, not how much went in. Phone before everything else begins, and you will learn what follows from there.
What to do next about petrol in a diesel
- Whenever you drive, your pump and the injectors wear. This is why you don't crank it, and why you don't trust it once it has started. The thing about petrol in a diesel in particular — the point most people get wrong — is that it drives off fine for the first mile or two. Diesel in a petrol engine typically cannot run at all, which stops the person and stops the wear with them. This one lets you drive on.
- Flicking the ignition on often primes your system, and priming is what pulls petrol out of the tank then into your pump and injectors. Those are the components diesel keeps oiled on its way through, before it ignites. Petrol handles the burning and none of the oiling. Leave the ignition be.
- Never add diesel on top to dilute it. A diesel fuel system will not tolerate petrol by percentage the way that advice presumes, and topping up removes nothing — it merely hands you a fuller tank of the same mixture. The type makes no difference either: super unleaded is just petrol.
- Stay put if it's wise to. Hazards on, motor off, leave the vehicle. Wherever you have stopped — the verge on Northwick Road, anywhere — an odd spot for us is better than a started engine, and nothing is quicker for us to sort than a vehicle that never shifted.
- A van arriving rather than circling hinges on two things: a postcode starting WR3 7, and whatever is nearest to you with a name on it. Have both prepared before you ring.
- Call 0333 366 0103. Expect three queries — what went in, about how many litres, plus whether the motor has been run. The answers shape all that comes after.
The drive back would about double it, for no gain at all. One commute has already put a real quantity of petrol-thinned diesel through the high-pressure pump of that Volkswagen Passat. So keep the car where it stands. Call us from the platform if that is handier — no one needs you standing over your car at Worcester Foregate Street whilst our engineers get on, and tonight is better than finding out on Monday.
We will come out to you, empty your tank, rinse your fuel lines and put clean diesel in so you can get home. So if petrol went into your diesel Skoda Octavia around Barbourne and you're stranded outside Co-op Food with a boot full of shopping, phone us — and don't start it again to get out of the space. A mile or so at gentle throttle pulls little of it, so these tend to be the simple jobs.
Nothing warns you, since from the driver's seat there's nothing to be warned about. The diesel Mercedes C-Class will have seemed entirely ordinary on the way back from Northwick Manor Primary School, and they all do — which is the trap with petrol in a diesel instead of the reverse. Diesel in a petrol motor generally refuses to run, stopping the motorist and stopping the damage with them. Petrol in a diesel starts, ticks over, pulls away as though nothing had happened, and all the while the pump keeps working without the lubrication its fuel is meant to supply. Tell us approximately how far, and how hard. The harder matters more.
A diesel injection system works hydraulically as well as chemically: your fuel has to hold pressure, not merely burn. Dilute that fuel and pressure which should build then stay built bleeds past tolerances instead, leaving the engine a weaker, later, less even delivery than it was engineered round. Petrol weakens diesel, and diesel has to be thick enough to seal the close-fitting components it runs through — that's the full process. It explains the normal Gheluvelt Park call too: a diesel Audi A3 that went out without complaint and came back down on power, lumpy at idle, perhaps smoking a little. None of which is the engine failing, and that's the bit worth hearing. The fuel has stopped behaving like diesel. Put your fuel right and it stops.
Hire car? Company car? Call them before us. Some agreements want the firm to sign off the work, and that's much faster dealt with up front than afterwards. Then give us a call about the Vauxhall Astra, the diesel one, near Ombersley Road Methodist Church. Do not worry that you can't say how full that tank was — almost nobody can two days into a car, and it's something we work out on the spot. The reason for asking: harm from petrol in a diesel is a matter of share. A couple of litres in an almost empty tank make a far stronger mixture than in a full one, and petrol is built to resist the very thing a diesel needs of that, which is igniting when compressed. Stronger blend, more rattling, more smoke, flatter throttle.
Forecourt drains for petrol in a diesel
It starts at a pump, typically. Often enough the job finishes on site as well. If you are still on the forecourt at Esso, that's typically where the drain takes place — we work on petrol station forecourts regularly, with the owner's consent.
Nowhere except the forecourt can it be halted with the motor still cold. Fuel pulled out of your tank and through your filter, all the way to the high-pressure pump, is what happens when the engine is fired up and the vehicle is driven to where it is now: the car park, the private drive or the lay-by, anywhere other than the forecourt. So the flush includes your filter and the lines along with the tank. That's still not a disaster, and our engineers sort it out where the vehicle stands. What decides it is whether the key was turned in the seconds after the till receipt was checked.
The staff will normally offer to move the vehicle out from the pump so the next motorist can get through. It is worth doing. Firing the car to move four vehicle lengths is not.
Parts our vans serve in Barbourne
Barbourne is a residential suburb, and so our vans go out to it and to the places near it on the usual runs: Northwick, Britannia Square, Astwood, Rainbow Hill and Little Eastbury.
Our engineers still come. Those places above are just the nearest neighbours, and a page is there for the majority of places around Worcestershire, so an absence from the list isn't an absence from our coverage. On the border, or anywhere the satnav misreads? Call us to check rather than assuming.
That map shows the area the page covers. All of it is territory our engineers serve: a kerbside, a forecourt, a driveway, a car park. You never bring your car anywhere.
Barbourne: stuck wherever you pulled up
Not everyone has the opportunity to stop anywhere sensible. A common call for us instead of a rare one: realised after setting off, finished up on the verge of Ombersley Road or at a lay-by with your hazards on.
Out of the car when it isn't safe to wait inside, with it when it is. It will frequently oblige. A diesel running on petrol limps along quite willingly, and that is the catch: fire it up to get to somewhere safer and the mixture goes further into the system with every mile driven. A technician heading to a difficult location is no trouble for us, and it's a lot better for the vehicle than driving on.
Already driven it? Petrol in a diesel after a couple of miles
under 3 miles from Barbourne, your M5 is what matters here. Lost power, a rough idle, smoke: those are the symptoms when they appear, rather than a neat stop — and a wrongly fuelled diesel will usually take you onto it and some distance along before anything seems wrong at all.
Don't start it to reposition. Pull off at the next sensible exit and switch off. Long run? Anything close to the under 3 miles to the closest city and you should assume the lot — filter, pump, injectors, all of that arrived at by the mixture. Say that on the phone, because it alters what goes in the van.
Barbourne itself
Barbourne is a suburban area located on the River Severn in Worcestershire, with a mix of semi-detached housing and other residential properties. Barbourne sits at an elevation of around 25 metres, close to the city centre of Worcester, which is approximately 1.3 miles away. Barbourne is near other local areas such as Northwick and Britannia Square, and is part of the larger Worcester urban area. Barbourne has a population of around 6827 people, according to recent estimates.
Our call-out in Barbourne, step by step
- Three things get checked before any quote — the fuel that was put in, the quantity, and whether anything has been run since. Each answer changes the work.
- Your tank is cleared of it.
- Lines rinsed, filter cleaned. Whatever is left after that isn't the thing that started the problem.
- Priming follows, once new diesel is in.
- Our engineers turn it on and make sure it runs correctly on clean diesel.
Your car is then ready for you to drive away. All of this is done where the car is, so it never has to go to a workshop, and when it has been noticed early, long-term damage is very unusual.
A separate matter: AdBlue in a diesel tank in Barbourne
If what was put in was AdBlue rather than petrol, the first instruction is unchanged — never fire it up — yet the issue is not. Diluted diesel, and no protection left for your fuel system that depends on it. That's petrol. AdBlue? Urea dissolved in water. Pour that in with the diesel and you get rust instead, plus build-up.
Frequently the more serious of the two, AdBlue — and the details sits on its own Barbourne page. Both are ours to handle.
Barbourne costs for a petrol-in-diesel drain
One price would not be honest here, since this isn't one job. These are the things that move it:
- Has it been run or driven? Nothing else matters for as much.
- The tank's capacity, set against how much of the wrong fuel went into it.
- The sort of fluid in the tank, petrol or AdBlue.
- Whether a van can sensibly get to your car and work on it, which hinges on where your car is.
Tell us your car, the amount and whether it has run, and you will get a firm answer instead of a range. For your car at home that's going nowhere and is not time-critical, works too.
Questions we get about petrol in diesel around Barbourne
Can you do a fuel drain at a petrol station in Barbourne?
Much of what we do takes place nowhere else. So yes. Our engineers work at Texaco and the other forecourts nearby regularly, with the site's consent — tell us which one you are at when you call and we'll tell you if our engineers can work there.
How much petrol is too much for a diesel?
Litres are not the measure. Proportion is, and far more than either, it matters whether anything has been run. Five litres into an almost dry tank is not five into a full one, no. But both land on the same question in the end: has that mix been drawn right through, or has it not?
I put petrol in my diesel and drove the car. What next?
Somewhere safe, then stop, then switch off and keep it off. It is salvageable much more often than drivers expect, even though driving is what moves the problem from your tank into the pump and injectors — and the single most helpful thing you can do now is not restart it.
Will a fuel drain void my warranty?
It is not an alteration, and so a drain and flush carried out correctly doesn't void a manufacturer's warranty. A dispute over a warranty is likelier to come from running a diesel on petrol — so leave it switched off.
Adding two-stroke oil, then driving home
What petrol has diluted isn't put back by two-stroke oil, which is an old workaround for a distinct problem. So no. The tank still has petrol in it later, and the pump still has to put up with it.
Main dealers and petrol in a diesel
Wherever the car is, our technicians drain and flush it there, so a trip to the main dealer does not come into it.
Is your vehicle still with you?
Shut off is the way it remains.
Switch it off somewhere sensible and leave it off, if you have already driven it. Cold, stationary, going nowhere: that's the best position to be in. Drivers fear this much more than they need to.
