Petrol in Diesel

0333 366 0103

Put Petrol in a Diesel Car in Thornliebank?

If you have not fired up the motor as yet, do not. A fuel drain and nothing else is almost always what a car needs while the fuel is still inside your tank and your engine has not yet run, which is why it's the following few minutes that count, not how much was put in. Petrol in Diesel travels to your car wherever it has ended up in Thornliebank or the remainder of East Renfrewshire, on the forecourt, by the roadside or on a private drive, and drains and flushes it there. Call us before everything else starts, so you'll know what follows after that.

What next? Petrol in a diesel, step by step

  • Give a petrol engine diesel and it will typically refuse to run at all, so the driver stops there and so does the wear. Give a diesel petrol and the engine starts, it ticks over, it moves off — fine enough for a few miles. People have that backwards, which is the bit they get wrong about petrol in a diesel specifically. So do not fire it up. And if started, do not depend on it: that fuel system is grinding while you drive.
  • Diesel burns, and before it burns it greases — your high-pressure pump, the injectors. Petrol manages only the burning. So leave your ignition alone too: switching it on is frequently sufficient to prime the system, and priming carries petrol from your tank into exactly those components.
  • That advice assumes a diesel fuel system tolerates petrol by percentage. It does not. Add diesel on top and nothing at all is removed; what you get is a bigger tank of the same mix. And no, the grade makes no difference — super unleaded is still petrol.
  • Stay where you are if you safely can. A car that has not moved is the simplest one to deal with, and our team would much rather drive to a tricky location than have it started. If you're stopped on the verge on Spiersbridge Avenue, switch your hazards on and keep the vehicle there.
  • Check where you are before ringing. A postcode starting G46 7, and the name of whatever is nearest to you. Otherwise the van circles instead of arriving.
  • What went in, approximately how many litres, plus whether your car has fired — those three replies shape the entire call-out. Dial 0333 366 0103 and tell us.

Can petrol be drained from a diesel on a forecourt?

It begins at a pump, generally. Frequently it finishes at one too. If you're still at the forecourt at Shell, that is typically where this drain gets done — we work on garage forecourts regularly, with the site's agreement.

At the forecourt, this gets spotted with your engine never run, and nowhere else manages that. Fuel sucked out of your tank and through the filter, all the way to your high-pressure pump, is what occurs when the engine is started and your car 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 takes in your filter and the fuel lines as well as that tank. That is still not a disaster, and our technicians put it right where the vehicle sits. What decides it is whether the key was reached for in the seconds after your receipt was checked.

Away from the petrol pump, the next motorist can get by — so yes, let the staff help you roll the car. Very much worth it. Starting it to roll four car lengths is not.

Mobile fuel drain van at a diesel car in Thornliebank

Car parks like the one at Co-op Food are somewhere our engineers work in all the time, and your fuel is seldom the complicated part. The bay is: cars either side, a trolley shelter behind, sometimes a height limit on the way in that decides whether a van can access you at all. So tell us how penned in you are when you phone, and which way your car is facing. If our engineers can't work beside the diesel Renault Clio we'll roll the vehicle without starting it — and that isn't fuss about a couple of seconds of running. Any start primes the fuel system and sucks more of that mix out of that tank and toward the pump, and so a car shunted twice into a nicer space has quietly grown into a bigger job than one left precisely where it stopped.

Try the trip home from Bank Pub? No. It will start and it will move off quite happily, which is the trouble — a diesel on a thinned tank acts generally while wearing the components the fuel should be protecting. Leave the BMW 3 Series and phone us.

Rarely the problem, the location. On-street is the usual location our technicians work, and a cramped parking spot is far preferable to a vehicle that has been driven somewhere more handy. What does help, when you call from near Thornliebank Community Library, is three things: the side the filler is on, whether our van can pull up next to without blocking the road, and if anything has run since you filled up. Then your Dacia Duster gets cleared, your filter changed where a workable one exists, the fuel lines flushed and fresh fuel put through the full circuit — because by now the worst of that is in the fuel lines, not the tank.

Knocking, an uneven idle, white smoke, a throttle gone soft. That is a misfilled diesel Mercedes E-Class telling you what's wrong. Turn off where you have stopped, close to St Vincent de Paul RC Church or anywhere else, and don't restart the car to find a better spot.

By now your tank is the least of it. Run a diesel and the mixture goes into the filter, into the lines, into your pump, into the rail — and none of that leaves with that tank contents. A diesel Audi A6 that made it near Thorntree Hall wants its circuit purged. Draining is not the same thing.

Thornliebank and the places next to it

The same runs take us to Carnwadric, Jenny Lind, Arden, Kennishead and Orchard Park along with Thornliebank, which is a residential suburb.

If yours isn't on this list it does not mean we never come — there are pages for nearly all towns around East Renfrewshire, and the ones named above are just the closest neighbours. Near the boundary, or somewhere your satnav gets wrong? Ring us to ask rather than assuming.

The map shows the patch the page includes. Roadside, forecourt, private drive, car park: every bit of that is ground we serve, and none of that requires your vehicle to move to us.

Broken down on the kerbside in Thornliebank

A chance to stop anywhere safe does not come to everyone. A normal call for us and not an odd one: worked out after setting off, finished up along the verge on Library Lane or at a lay-by with your hazards flashing.

Whether you remain beside the motor or stand away from it hangs on whether staying nearby is wise. It will usually oblige. A diesel running on petrol limps along very willingly, and that's the problem: start it up to get to somewhere handier and that blend goes further into the fuel system with every mile driven. However difficult the location, it is no bother for us to come to it, and that is much better for the car than carrying on.

A couple of miles on petrol in a diesel: what now?

under a mile out of Thornliebank, the local M77 is what matters here. It will usually take you onto it, and some way along, before you spot a thing. Then it's smoke, a lumpy idle and power falling away — not a neat stop. Misfilled diesels rarely give you one of those.

Take the next exit that's safe, stop there, and do not restart the car to move it. Long run? Anything approaching the under 10 miles to the nearest city and you should assume the lot — filter, pump, injectors, all of that got to by the petrol. Say that on the phone, since it affects what goes in the van.

Thornliebank itself

Thornliebank is a suburban area situated on the riverside in East Renfrewshire, with a mix of flat housing and local amenities. Thornliebank lies close to the city of Glasgow, approximately 5 miles from the city centre, and is near other suburban areas such as Carnwadric and Arden. Thornliebank has a relatively low elevation of around 38 metres above sea level, and its population is approximately 6202 residents. Thornliebank is connected to the wider region through its proximity to Glasgow and other nearby places like Jenny Lind.

When we arrive with you around Thornliebank: what happens

  • The responses change the work, which is why our engineers ask before pricing: what got in, how much of it, and if the engine has run.
  • Out comes the tainted fuel.
  • Our technicians purge the lines and clean your filter, and so what is remaining in your system is not what created the problem.
  • The system gets primed, on new diesel.
  • The engine is fired up and checked to be sure it runs properly on clean diesel.

That leaves it ready to set off. We do all of it wherever your car has come to a stop, which means it never needs to be taken to a garage, and if it has been caught soon, it is very rare for there to be lasting damage.

Thornliebank AdBlue removal is a different job

If what got in was AdBlue rather than petrol, the opening instruction is the same — never start the vehicle — but the issue isn't. Petrol thins your diesel and removes the lubrication the fuel system depends on. Urea in water, AdBlue, and in a diesel tank that brings rust and deposits.

AdBlue removal in Thornliebank has a page of its own with the full story on it, including why it's often the more significant of the two. Our engineers handle both.

What a petrol-in-diesel drain will cost in Thornliebank

What changes the price is set out below, because the job isn't one job and we cannot frankly put a single figure on this page.

  • Has it been run or driven? Nothing else counts for as much.
  • The tank's capacity, set against how much of the wrong fuel went into it.
  • Which got in: petrol or AdBlue.
  • Access: the car's position, and if working on it there's safe for our van.

The car, the quantity, whether it has run — give us those and the answer comes back straight and not as a range. For your car at home that's going nowhere and isn't pressing, is fine too.

Petrol in diesel questions from Thornliebank drivers

At a petrol station in Thornliebank, can you do a fuel drain there?

A good part of this work gets done there, so yes. Consent from the site is the condition. Given that, a forecourt like BP is somewhere we are often enough, along with the rest of them locally — so name yours on the phone and you'll hear if working there is possible.

Is there a sensible quantity of petrol in a diesel?

Whether the motor has run matters far more, though the proportion matters too, instead of the litres. What determines how much work is needed is if that mix has been sucked through the system — since even though five litres in an almost empty tank is a different case from five in a full one, either way that is the query.

I put petrol in my diesel and drove the car. What now?

Somewhere sensible, then stop, then turn off and leave it off. Driving takes the problem along — out of the tank, into the pump and injectors. Motorists fear it a good deal more than the recovery rate warrants, mind. The one really helpful thing left to you is not restarting it.

Will a fuel drain void my warranty?

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

Adding two-stroke oil, then driving home

No. Two-stroke oil is an old workaround for a distinct problem and it does not restore what petrol has thinned. Your pump still has to cope with it, because the tank still has petrol in it afterwards.

A main dealer for petrol in a diesel — necessary?

There's no need to bring it to a franchised dealer, because our technicians drain and flush the vehicle wherever it is.

You, and your car, still together?

Your engine remains off.

Turn it off somewhere sensible and leave it off, if you have already driven it. This is recoverable from a lot more frequently than motorists expect, and a parked, cold vehicle is the best position to be in.
