Petrol in Diesel

Put Petrol in a Diesel Car in Battle Field?

Petrol in Diesel drains and cleans wrong-fuelled vehicles where they sit, on the forecourt, by the roadside or on a drive, throughout Battle Field and the remainder of Shropshire. The very first thing to do is not to turn on the motor. While the engine has not yet run and the petrol is still sitting in that tank, a tank drain is almost always all it needs, and the following few minutes decide that, not how much went in. Ring us and our engineers will tell you what comes after that before you attempt anything else.

Petrol in a diesel: what to try now

  • Do not fire it up — and don't believe it when it fires up. Here is the thing drivers have wrong about petrol in a diesel especially. A petrol engine given diesel usually just won't run, so the driver stops and the damage halts with them. A diesel filled with petrol typically starts, ticks over and moves off perfectly well for several miles. It isn't okay. It is grinding your fuel system whenever you drive.
  • Flicking the car's ignition on commonly primes the system, and priming is what carries petrol out of the tank then into your pump and injectors. Those are the parts diesel keeps lubricated on its way through, before it burns. Petrol handles the burning and none of the lubricating. Leave the ignition alone.
  • Don't dilute it. Diesel poured on top gets rid of nothing, so all you get is more of what was already there, because percentage is not how a diesel fuel system copes with petrol. Super unleaded? Simply petrol. The grade makes no difference.
  • Sit tight if it's wise to. Hazards on, motor off, keep the car. Wherever you have stopped — the verge on Helmeth Road, anywhere — a difficult location for us is better than a started diesel, and nothing is easier for us to sort than a car that never moved.
  • Keep your location prepared before you phone. A postcode beginning SY6 7 and whatever is closest to you with a name on it is the difference between our van turning up and the van circling.
  • Dial 0333 366 0103. Prepare for three questions — what got in, roughly how much, plus whether the engine has been started. Your responses shape everything that comes after.

Do not drive it home. Petrol-thinned diesel has passed through that high-pressure fuel pump in real volume on the trip in, and the trip back would about double that for nothing at all. Call us — the platform is fine. There's no need to stand over that Volkswagen Passat at Church Stretton whilst the work goes on, and we'd much rather talk to you tonight than realise on Monday.

Put diesel in a petrol motor and usually it will not run, and so the motorist stops there and the damage stops with them. Swap it — petrol into a diesel — and the thing starts, idles and drives off as though nothing had happened, whilst the high-pressure fuel pump works without the protection the fuel is supposed to be giving. That is the trap, and it's why the diesel Mercedes C-Class will have seemed entirely usual coming back from St Lawrence CofE Primary School. They do. From behind the wheel there is nothing to warn you about, so nothing alerts you. Call us with approximately how far you went, and how hard; the second one matters more than the first.

None of it is the motor failing. That is the bit worth hearing, and it is why the usual Coppice Leasowes Nature Reserve call ends better than it sounds: a diesel Peugeot 3008 drives out there without fuss, comes back with the power gone, your idle rough and perhaps a little smoke, and the cause is the fuel no longer acting like diesel. Diesel has to be viscous enough to seal the precision components 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 escapes past gaps, delivery turns up weaker and later and less even than designed, and all of that stops once your fuel is corrected.

Rattling? Lumpy idle? White smoke, throttle gone limp? That's your misfilled BMW 1 Series, a diesel, saying what is wrong with it. Stop wherever you happen to be, perhaps close to Church Stretton Methodist Church, and leave the restarting alone.

No dashboard light exists for this, which is why cars in that position typically get driven again before anyone rings. Do not be one of them. The throttle went limp and the idle turned lumpy after a couple of streets, and your diesel Kia Sportage is now sitting close to Church Stretton Swimming Pool. Softness there means fuel that can't build pressure properly instead of a motor packing up. Turn off. Phone us.

At the forecourt: removing petrol from the diesel

A large part of the work gets finished at a forecourt, because that is where it mostly begins. If you're still at the forecourt at Applegreen, that's usually where the drain gets done — our technicians work on garage forecourts regularly, with the owner's consent.

Before your motor has started — a garage is the only location this is caught. The few seconds between checking the till receipt and going for the keys settle how much requires rinsing. Anywhere other than a forecourt — a car park, a private drive, a lay-by — the vehicle was started and driven to get there, so fuel was drawn from your tank, through the fuel filter and into your high-pressure pump. That means the lines and the filter require rinsing as well as the tank. It is not a catastrophe, and our engineers can still put it right where the vehicle is.

Out from the petrol pump, the next motorist can get by — so yes, let the attendants help you wheel the car. Well worth doing. Rolling the car four lengths does not justify firing it.

Do our technicians cover your end of Battle Field?

These same journeys take us to Hazler, Church Stretton, Cunnery, Ashbrook and Worldsend along with Battle Field, which is a residential suburb.

There are dedicated pages for the majority of locations across Shropshire, and the ones named above are just the immediate neighbours — so yours being absent from the list means nothing whatsoever about if we come. Presuming is the thing to avoid, especially on the border or anywhere your satnav struggles. Call us to ask.

The ground this page covers is on our map. Every bit of it is ground we cover: a kerbside, a forecourt, a private drive, a car park. You never bring your car anywhere.

Battle Field: broken down where you pulled up

Some people find no suitable spot to pull in at all. Hazards on in a lay-by somewhere, or pulled onto the verge of Oaks Road as you realised after setting off — we take that call often enough that it is the normal kind.

Wait with the vehicle when it's sensible to be there, yet clear of the vehicle when it is not. It will usually oblige. A diesel running on petrol limps along very willingly, and that is the problem: start it up to get to somewhere handier and that mix goes further into the system with every mile travelled. We'll take the van to an inconvenient location without any fuss, and for your car that is far better than carrying on.

Run it already? Stop, then check this

This is where the M54 comes in — under 15 miles away from Battle Field. A drop in power, a rough idle, smoke: those are the signs when they appear, instead of a tidy stop — and a misfuelled diesel will usually take you onto it and some distance along before anything seems wrong at all.

Take the next junction that's safe, pull up there, and do not start the vehicle to reposition. It affects what our technicians bring, so say so when you ring: on a longer run — anything near the under 50 miles to the closest city — take it the contamination has been through the filter, your pump and your injectors.

All about Battle Field

Battle Field is a suburban area in Shropshire, situated near the River Onny and characterised by detached housing. Battle Field sits at an elevation of 198 metres, overlooking the surrounding countryside. Battle Field is located near several nearby places, including Hazler, Church Stretton, and Cunnery, and is approximately 28 miles from Wolverhampton. Battle Field has a population of around 1651 residents.

What we do when our engineers arrive with you around Battle Field

  • Three things get checked before any quote — your fuel that was put in, the amount, and if anything has been run since. Each answer shapes the work.
  • Away flows the polluted mixture.
  • Lines cleaned, filter cleaned. Whatever is left later on isn't the thing that caused the trouble.
  • The fuel system gets primed, on new diesel.
  • The motor is turned on and tested to be sure it runs smoothly on clean diesel.

The car is then ready for you to pull away. Lasting damage is very rare when it has been spotted quickly, and since all of it is done where the car is, it never has to go to a workshop.

AdBlue in your diesel tank instead, in Battle Field?

If what went in was AdBlue instead of petrol, the first rule is the same — do not crank it — yet the fault is not. Petrol dilutes your diesel and takes away the lubrication the system relies on. AdBlue is urea dissolved in water, and in a diesel tank it brings rust and residue instead.

Frequently the more significant of the two, AdBlue — and the details sits on its own Battle Field page. Both are ours to deal with.

Battle Field prices for a petrol-in-diesel drain

One figure wouldn't be fair here, since this is not one job. These are the things that shift it:

  • This is the main one: whether the motor has been run, or driven.
  • How much of the wrong fuel went in, judged against how much the tank takes.
  • AdBlue or unleaded, whichever went in.
  • Where is it? And can our van get to it and work there sensibly?

Tell us your vehicle, the amount and if it has run, and you'll get a clear answer instead of a range. Not urgent, with the vehicle at home and going nowhere? Then works.

Petrol in diesel questions from Battle Field drivers

I am on a forecourt in Battle Field. Can you drain the vehicle here?

Much of what our technicians do happens nowhere else. So yes. Permission from the site is the condition. Given that, a forecourt like another forecourt nearby is somewhere we're often enough, along with the rest of them locally — so name yours on the phone and you'll hear if working there's possible.

How much petrol is too much for a diesel?

Ratio settles it rather than litres — and more than either, whether your motor has run. Five litres into a nearly dry tank isn't five into a full one, no. But both land on the same query in the end: has that mix been pulled right through, or has it not?

I drove it after putting petrol in my diesel. What next?

Pull over somewhere sensible, switch off, then keep the vehicle off. It is recoverable far more regularly than drivers assume, even though driving is what moves the trouble from that tank into the pump and injectors — and the single most useful thing you can do now isn't restart it.

My warranty — does a fuel drain void it?

It's not a change, and so a drain and flush carried out correctly does not void a manufacturer's warranty. Running a diesel on petrol is the thing more likely to cause an argument with one, which is another good reason to leave it turned off.

Could I put some two-stroke in and just drive?

What petrol has thinned is not restored by two-stroke oil, which is an old workaround for a different issue. So no. Petrol stays in that tank afterwards, whatever else goes in, and your pump gets no reprieve from it.

Do I need a main dealer for petrol in a diesel?

Not at all. We drain and flush the car wherever it is, so there's no need to bring it to a dealership.

You, and your vehicle, still together?

The motor stays off.

Already driven it? Then pull over somewhere sensible, switch off, and let the car stay that way. Cold, still, going nowhere: that is the best place to be in. Motorists fear this much more than they need to.

Draining wrongly fuelled vehicles, Battle Field and the rest of Shropshire, wherever they are. Roadside. Forecourt. Home.
