Petrol in Diesel

0333 366 0103

Put Petrol in a Diesel Car in Glenfield?

With your tank still carrying the fuel and your engine not yet started, nearly every job requires only a drain, so keep the engine off. That result is decided in the minutes straight after the fill-up, rather than by the amount that got in. Throughout Glenfield and the remainder of Scottish Borders, Petrol in Diesel drains the vehicle and cleans it where it sits, whether by a roadside, on a drive or at a forecourt. Our team can show you what your next part will be. Ring us — that comes before everything else.

What to try now about petrol in a diesel

  • Feed a petrol motor diesel and it will typically refuse to run at all, and so the person stops there and so does the harm. Give a diesel petrol and the engine starts, it ticks over, it moves off — fine enough for a couple of miles. Motorists have that backwards, which is the bit they get wrong about petrol in a diesel especially. So don't crank it. And having started, don't depend on it: that fuel system is wearing down whenever you drive.
  • Leave the car's ignition off as well. Diesel does two roles: it combusts, and before it ignites it protects the injection pump and the injectors. Petrol handles the first and not the second. Flicking your ignition on is often sufficient to prime that system, which carries the petrol out of the tank then into precisely those components.
  • Topping up gets rid of nothing. It hands you a larger tank of the same blend, since a diesel fuel system will not accept petrol by percentage as that advice assumes — so never pour diesel on top to water down it. Octane is irrelevant too: super unleaded is petrol.
  • Stay still if it is sensible to. Hazards on, engine off, leave the vehicle. Wherever you have stopped — the verge on Glenfield Terrace, anywhere — an awkward spot for us beats a started diesel, and nothing is easier for us to deal with than a car that never shifted.
  • Check where you are before calling. A postcode that starts TD1 2, and the name of whatever is closest to you. Otherwise the technician circles instead of showing up.
  • Three facts decide the entire visit: the liquid you tipped in, the approximate amount of it, and whether it has been running since. The line is 0333 366 0103.

On the forecourt: clearing petrol from a diesel

The job starts at the pump, usually. Often enough it ends there as well. If you are still on the forecourt at Asda, that's typically where this drain happens — our technicians work on petrol station forecourts routinely, with the station's permission.

Nowhere else but the forecourt can it be caught with the engine still unrun. We can still sort it out where it sits, even away from the forecourt. In a car park, on a driveway or in a lay-by, the vehicle has been switched on and driven there, and that sucked fuel through the fuel filter and into the high-pressure pump, right from your tank. None of that is a disaster, though the flush then has to reach past that tank to your lines and the fuel filter, and the few seconds between seeing the receipt and going for the keys are what determine that.

The staff will generally offer to roll the car away from the pump so the next motorist can get past. That is worth doing. Firing it just to shift four car lengths is not.

Mobile fuel drain van at a diesel car in Glenfield

The awkward part is the bay, not your fuel. Cars either side of you, a trolley shelter behind, and occasionally a height limit on the way in that settles if our van can get to you at all — so when you ring from a car park like the one at Asda, say how much space there's about you and which way round the vehicle is. Those our technicians cover frequently. Should there be no room to work alongside the diesel Volkswagen Tiguan, it gets shifted with your engine off, and not out of pedantry over a couple of seconds of running: priming occurs at every start, more of the mix departs the tank for your pump, and two shunts into a better bay have gradually made a bigger job of what was merely a car sitting still.

The parts that should be getting oiled are wearing down instead, and your car gives no sign of it: a diesel on a diluted tank fires up and pulls away just fine. Chance the journey home from The Woodcutter? Don't. Phone then leave the Audi A4 where it is.

Never drive it home to buy yourself time. You already have it: nothing gets worse whilst the vehicle stands, since a diesel Ford Focus left outside Public Park is doing none of what it did on the way there. The pump has stopped turning.

Switch off where you have stopped, and don't restart it to find somewhere better — close to Pavilion Cinema or anywhere at all. Clattering, a ragged idle, white smoke and a limp throttle are a misfuelled diesel Vauxhall Astra telling you what is wrong.

A couple of streets, then it stopped. Throttle dead, idle ragged, and the diesel Kia Sportage is parked up near Our Lady and St Andrew RC Church. The engine is not packing up — that deadness is fuel that will not build pressure. There's no light on the dash for it, so cars like yours generally get driven again before anybody picks up the phone. Don't. Off, then call us.

Glenfield plus the towns next to it

Being a residential suburb, Glenfield gets a regular call, whilst its neighbours nearby come with it on that same run: Langlee and Netherdale, Old Town and Galashiels, Gala Park.

There are pages for most towns around Scottish Borders, and the ones named above are merely the immediate neighbours — so yours being absent from the list means nothing about whether our engineers come. Contact us to enquire rather than presuming, particularly when you're on a boundary or anywhere the satnav gets wrong.

See this map for the patch shown here. We work roadside, on forecourts, on driveways and at car parks throughout all of that, and your car doesn't need to travel to us.

Kerbside call-outs across Glenfield

A chance to pull over anywhere suitable does not come to everybody. If you realised after setting off and ended up by the verge beside Glenfield Crescent, or in a lay-by somewhere with your hazards on, that is a common call for us and not an unusual one.

Wait beside the motor while it's safe to wait in it, but clear of the vehicle if it's not. Don't restart it to reach a better location. It will go — a diesel on petrol usually obliges — and each mile of obliging drags the mix deeper into your fuel system. However inconvenient the place, it's no bother for us to come to it, and that's much better for your car than pressing on.

Run it already? Pull over, then see below

This is where the local M8 comes into it — under 50 miles from Glenfield. A loss of power, an uneven idle, smoke: those are the symptoms when they arrive, instead of a neat stop — and a wrongly fuelled diesel will frequently get you onto it and some distance along before anything feels wrong at all.

Take the next junction that is safe, pull up there, and do not start it to reposition. It alters what we bring, and so mention it when you call: on a longer drive — anything near the under 50 miles to the closest city — take it the mixture has been through the fuel filter, the pump and the injectors.

All about Glenfield

Glenfield is a suburban area situated on the riverside in the Scottish Borders, with a mix of flat housing and local amenities. Glenfield sits at an elevation of 136 metres, near the communities of Langlee, Netherdale, and Old Town. Glenfield is located approximately 28 miles from Edinburgh, making it a commuter base for the city. Glenfield has a population of around 2563 residents, who enjoy the area's scenic riverside setting.

When our engineers get to you in Glenfield: what happens

  • Our technicians check what got in, how much, and whether your engine has run. The replies shape the work, which is why our engineers ask before giving a price.
  • The polluted mixture comes out of your tank.
  • What is remaining in the fuel system shouldn't be what caused the problem, and so the lines get purged and the fuel filter cleaned.
  • Priming follows, once clean diesel is in.
  • The motor is started and tested to be sure it runs smoothly on fresh diesel.

Then it's ready to drive away. Long-term damage is very unusual when it has been noticed early, and because all of it is done where the car is, it never needs to go to a workshop.

AdBlue in a diesel tank around Glenfield is a separate matter

AdBlue rather than petrol? Then the first step is unchanged — your motor stays off — while the issue underneath it's a distinct one altogether. Petrol weakens your diesel and removes the protection your fuel system depends on. Rust and build-up are what a diesel tank gets instead, because AdBlue is urea in water.

AdBlue removal in Glenfield has a page of its own with the full story on it, including why it is usually the more significant of the two. Our technicians deal with both.

Glenfield costs for a petrol-in-diesel fuel drain

Our engineers can't put one price on this page truthfully, because the job isn't one job. What moves it:

  • Whether your motor has been run or driven. This is the main one.
  • Wrong fuel in, against what that tank takes — that proportion.
  • AdBlue or unleaded, whichever got in.
  • Access: the vehicle's position, and if working on it there's sensible for our van.

The car, the quantity, whether it has run — give us those and the answer comes back straight instead of as a range. Not time-critical, with the vehicle at home and going nowhere? Then is fine.

Things our technicians get about petrol in diesel in Glenfield

Fuel drains on a Glenfield petrol station forecourt

Plenty of what our engineers do gets done nowhere else. So yes. Tell us which one you're at when you phone and we'll tell you if our technicians can work there. With the station's consent we attend Esso and the other forecourts locally all the time.

How much petrol in a diesel is too much?

It depends on the proportion instead of the litres, and much more on whether the engine has run. What determines how much work is required is whether that blend has been drawn through the system — since though five litres in a nearly empty tank is a separate case from five in a full one, either way that is the question.

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

Pull over somewhere safe, turn off, and leave it off. Not restarting it is the single most useful thing available to you now. Driving does shift the trouble out of your tank then into the pump and injectors, yes, and it remains fixable a lot more often than motorists fear.

Is a fuel drain going to void my warranty?

No. Carried out correctly, clearing and cleaning is no modification at all, and the warranty from your manufacturer is unaffected by it. Running a diesel on petrol is the thing more likely to cause an argument with one, which is another good reason to leave the vehicle turned off.

Adding two-stroke oil, then driving home

No. It belongs to a separate fault from a different era, and petrol has weakened something no oil of that kind replaces. The tank still has petrol in it later, and your pump still has to cope with it.

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

There's no need to bring it to a dealership, as our technicians drain and flush your car wherever it is.

You, and your car, still together?

Leave the engine turned off.

Turn it off somewhere safe and leave it off, if you have already driven it. Cold, parked, going nowhere: that is the best position to be in. Motorists fear this much more than they need to.

Throughout Scottish Borders and around Glenfield: call-out fuel draining, at home or on the forecourt or at the kerbside.
