Petrol in Diesel

Tollcross: Put Petrol in a Diesel Car?

If you have not turned on your engine as yet, don't. A fuel drain and nothing else is almost always what a car requires while the petrol is still sitting in your tank and the engine has not turned over, which is why it's the coming few minutes that count, not how much got in. Petrol in Diesel goes to your car wherever it has come to rest in Tollcross or the remainder of Glasgow City, on the forecourt, at the roadside or on a drive, and drains and flushes it there. Contact us and we can tell you what happens from here before you do much else.

What to do first about petrol in a diesel

  • Don't start it. Turned on all the same? Then never trust it. Diesel in a petrol car generally can't run, and so the motorist stops and the harm halts with them. Petrol in a diesel? It starts. It idles. It pulls away normally, for several miles. People get that reversed. It isn't all right — that fuel system is wearing every mile you cover.
  • Switching the car's ignition on usually primes that system, and priming is what draws petrol out of your tank then into your pump and injectors. Those are the parts diesel keeps oiled on its way through, before it ignites. Petrol does the burning and none of the oiling. Leave your ignition off.
  • Topping up clears nothing. It leaves you a larger tank of the same blend, since a diesel fuel system does not accept petrol by percentage in the way that advice implies — so don't put diesel on top to dilute it. Grade is irrelevant too: super unleaded is petrol.
  • Remain where you are if you reasonably can. A vehicle that has not shifted is the easiest one to deal with, and we'd sooner get to an awkward place than have it started. If you are stopped on the verge on Dalness Street, switch the hazards on then leave the vehicle there.
  • Before you ring, work out your whereabouts. Anything closest to you with a label on it, plus a postcode beginning G32 8 — that's what determines whether the technician turns up or circles.
  • Dial 0333 366 0103. Let us know what went in, approximately how many litres, plus whether the motor has fired. These three replies determine the full job.

The drive in is what pulled diluted diesel through the pump. Standing still has pulled nothing. Petrol in a diesel Volkswagen Tiguan, sitting at Carntyne all day, waits harmless in that tank whilst it waits. Call us first — before your keys come out.

Every restart primes the fuel lines and pulls more petrol through your filter and into your pump. So a wrongly fuelled diesel Nissan Qashqai on the zig-zags outside the local primary school is a hassle, while the same motor fired up three more times to be polite is a fuel system rather than a tank. A passer-by will tell you to shift the vehicle out of the gateway and sort it out later. Don't. Leave it there, let them complain, and call us.

Here is what a job in the car park by The Weaverley normally looks like. Our engineers arrive at your car, ask what went in, roughly how much, and whether your engine has run since — those three answers settle most of the work. Then the tainted mixture comes out of that tank, your lines get cleaned, and the filter comes off where your Ford Focus has a serviceable one. Clean diesel goes in and the system is bled. Then our engineers start the engine, make sure it runs properly, and you pull away.

None of it is the motor failing. That's the bit worth hearing, and it is why the normal Amulree Recreation Ground call ends better than it sounds: a diesel Mercedes C-Class drives out there without fuss, comes back with the power gone, the idle lumpy and possibly a little smoke, and the cause is your fuel no longer behaving like diesel. Diesel has to be thick enough to seal the tightly fitted parts it runs through; petrol dilutes 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 clearances, delivery turns up poorer and later and less even than designed, and all of that stops once your fuel is sorted.

What occurs next is the issue. Your engine straight away pulls the petrol left sitting in the fuel filter and the feed lines back round through your pump a second time, since draining a tank does nothing about fuel that has already left it. Drain it then put new diesel in, someone confident will tell you — and that suggestion is only half right, since do it to a diesel Kia Sportage parked up, Glasgow Club Tollcross say, and the thing starts, which is what makes it sound plausible. Ring us instead. Our technicians flush the circuit and take your filter off where the vehicle has a working one, and that is the difference between your car being put right and the vehicle merely starting.

Clearing petrol from the diesel on a forecourt

Pumps are where this job mostly starts, and where a good share of it finishes. The drain typically takes place on the spot. Still on the forecourt at Shell? Given the owner's consent, that is somewhere our engineers work, and regularly.

No place other than the forecourt can the mistake be stopped with the motor still untouched. Everywhere else — a car park, a private drive, a lay-by — the vehicle was fired up and driven to get there, which means fuel was sucked from the tank, through the filter then into the high-pressure fuel pump. That's not a calamity, and our engineers can still deal with it where it stands. It does mean the fuel lines and your filter need cleaning as well as that tank, and that is decided by the few seconds between checking your receipt and going for your key.

Roll it out of the way if the attendants offer, and they generally will. The next motorist gets by the pump, and that's worth doing. Moving the car four lengths does not merit starting it.

Service in Tollcross

Braidfauld, Dalbeth, Fullarton, Shettleston, Sandyhills — every one of them on the runs that bring us across to Tollcross as well, a residential suburb.

There are pages for the majority of locations around Glasgow City, and the ones named above are simply the immediate neighbours — so yours being missing from this list means nothing at all about if we come. Call us and check instead of presuming, particularly if you are on a boundary or somewhere a satnav misreads.

Check the map for the patch covered on this page. The lot is territory our technicians serve: a kerbside, a forecourt, a private drive, a car park. You don't drive your car anywhere.

Broken down by the roadside around Tollcross

The opportunity to pull over anywhere safe doesn't fall to everybody. A normal call for us rather than an odd one: realised after setting off, ended up on the verge beside Tollcross Road or in a lay-by with the hazard lights going.

Okay there? Wait by it. Not safe? Move out and clear of it. Never fire it up to reach a better location. It'll go — a diesel on petrol generally obliges — and each mile of obliging pulls that mix deeper into the system. A technician driving to an awkward spot is no trouble for us, and it's a lot better for the vehicle than driving on.

Petrol in a diesel, and the car has travelled

under a mile out of Tollcross, the M74 is what counts now. A misfilled diesel will often take you onto it and some distance along before anything feels wrong, and the symptoms when they appear are normally lost power, a lumpy idle and some smoke rather than a clean stop.

The next sensible junction is the one to take. Switch off there, then leave the restarting alone. On a longer drive — anything approaching the under 3 miles to the nearest city — take it the contamination has been through the filter, the pump and your injectors, and say so when you phone. It changes what we bring.

All about Tollcross

Tollcross is a suburban area in Glasgow City, situated on the riverside at an elevation of 27 metres, with the River Clyde flowing nearby. Tollcross is located approximately 2.8 miles from Glasgow city centre and is surrounded by other suburban areas such as Braidfauld and Dalbeth. Tollcross is predominantly composed of flat-type housing, which is typical of many Glasgow suburbs. Tollcross has a population of around 6436 residents, according to recent estimates.

When our technicians arrive with you around Tollcross: what follows

  • We find out what got in, how much, and if the motor has run. The responses shape the work, which is why we ask before giving a price.
  • Out flows the contaminated mixture.
  • What is remaining in your system shouldn't be what created the trouble, so the fuel lines get rinsed and the fuel filter cleaned.
  • We put fresh diesel in and bleed your system.
  • Our engineers turn it on and confirm it runs properly on new diesel.

Your car is then ready for you to drive away. Permanent damage is very uncommon when it has been caught soon, and as all of it is done where your car is, it never has to be taken to a workshop.

AdBlue in a diesel tank around Tollcross is a distinct matter

If what got in was AdBlue rather than petrol, the first instruction is unchanged — never fire it up — yet the issue isn't. Petrol does two things to diesel: thins it, and strips out the lubrication the fuel system relies on. Urea in water, AdBlue, and in a diesel tank that brings corrosion and deposits.

AdBlue removal around Tollcross has a page of its own with the details on it, including why it is often the more serious of the two. Our engineers cover both.

Tollcross costs for a petrol-in-diesel drain

What moves the price is listed below, as the job isn't one job and we cannot honestly put a single number on this page.

  • Started? Driven? Either answer counts more than anything else on this list.
  • How much of the wrong fuel got in, weighed against how much that tank can hold.
  • Which got in: petrol or AdBlue.
  • Whether a technician can safely reach your vehicle and work on it, which hinges on where the vehicle is.

The vehicle, the amount, whether it has run — give us those and the answer comes back clear instead of as a range. If it is not urgent — your car is at home and going nowhere — is fine too.

Petrol in diesel: common queries in Tollcross

Fuel drains on a Tollcross petrol station forecourt

Yes — forecourts are where a large portion of this takes place. Consent from the site is the condition. Given that, a forecourt like Esso is somewhere we are frequently, along with the rest of them locally — so name yours on the call and you'll hear if working there is possible.

How much petrol in a diesel is too much?

Whether the motor has run counts much more, though the proportion matters too, instead of the litres. What settles how much work is required is if that blend has been sucked through your fuel system — since although five litres in an almost empty tank is a different matter from five in a full one, either way that is the question.

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

Somewhere sensible, then stop, then turn off and keep it off. Not restarting it is the single most valuable thing available to you now. Driving does move the trouble out of the tank then into your pump and injectors, yes, and it remains recoverable a lot more regularly than people fear.

Is a fuel drain going to void my warranty?

A manufacturer's warranty survives a drain and flush done to a proper standard, which is no alteration at all. Another reason to leave it turned off: running a diesel on petrol is the thing more likely to cause a dispute with one.

Can I just add two-stroke oil and drive home?

What petrol has weakened is not restored by two-stroke oil, which is an old workaround for a separate problem. So no. The tank still has petrol in it afterwards, and the pump still has to put up with it.

Does petrol in a diesel have to go to a main dealer?

There's no need to take it to a dealership, since our engineers drain and clean the car wherever it is.

Is your car still with you?

Don't turn your engine back on.

Already driven it? Then stop somewhere sensible, switch off, and let the car stay that way. This is recoverable from a lot more frequently than motorists fear, and a still, cold vehicle is the best place to be in.
