# Put Petrol in a Diesel Car in Possil Park?

Petrol in Diesel drains and flushes misfuelled vehicles where they stand, on the forecourt, at the roadside or on a drive, across Possil Park and the remainder of Glasgow City. The very first thing to do is not to fire up the engine. When the motor has not run and the fuel is still in the tank, a tank drain is almost always all it takes, and the coming few minutes decide that, not how much was put in.

Contact us before everything else starts, so you will know what happens from there.

## Now what? Petrol in a diesel, step by step

- Feed a petrol motor diesel and it will typically fail to run at all, and so the person stops there and so does the damage. Feed a diesel petrol and the thing starts, it idles, it pulls away — fine enough for a few miles. People have that muddled, which is the thing they get wrong about petrol in a diesel in particular. So don't start it. And having started, do not depend on it: the fuel system is grinding whenever you drive.

- Diesel combusts, and before it ignites it protects — that high-pressure pump, its injectors. Petrol does only the burning. So leave your ignition off also: switching it on is frequently enough to prime the system, and priming carries petrol from that tank into precisely those parts.

- Do not water down it. Diesel added on top takes out nothing, so all you have is more of what was already there, since percentage is not how a diesel fuel system accepts petrol. Super unleaded? Simply petrol. The octane makes no difference.

- We would sooner get to a difficult location than have it started — so if you sensibly can, stay still. Nothing is easier to deal with than a motor that hasn't shifted. On the verge on Denmark Street, that means hazards on then leave the car.

- Know where you are before calling. A postcode beginning G22 6, and the name of whatever is next to you. Otherwise the van circles rather than arriving.

- Three details settle the whole job: the fuel you tipped in, the approximate measure involved, plus if anything has been running since. The number is 0333 366 0103.

The high-pressure pump spent that morning commute labouring on a fuel that had lost most of the protection it is designed around. Diesel protects that pump, and the fuel injectors with it, before any of the fuel ignites; petrol does the burning and none of the oiling. So take a diesel Volkswagen Golf, fuelled at quarter past eight, driven in to work, and left standing outside Ashfield until you realise close to eleven. Three hours of standing have altered nothing about it. The few miles before that altered a good deal, which is why the thing we ask is about miles instead of hours. Phone. Keep the car right where it is.

## Can petrol be pumped out of a diesel at a forecourt?

Plenty of the job starts at a forecourt, meaning a big part of it gets done there.

Still at Shell? Then that is typically where it gets done. Station forecourts are normal for us, with the agreement of the owner.

A filling station is the single setting it can be halted before your engine has started.

Fuel drawn out of your tank and through the filter, right to the high-pressure pump, is what happens when the motor is switched on and your car is moved to where it is now: the car park, the drive or the lay-by, everywhere other than the forecourt. So the flush covers the fuel filter and the fuel lines as well as that tank. That's still not a calamity, and our engineers sort it out where the vehicle stands. What settles it is whether the key was turned in the seconds after the till receipt was read.

The staff will normally help you push the car clear of the petrol pump so the next customer can get by. That is worth doing.

Shifting it four lengths doesn't merit cranking it.

## Do we serve your part of Possil Park?

These same runs bring us to Cowlairs, Parkhouse, Hamiltonhill, Milton and Firhill besides Possil Park, which is a residential suburb.

If yours is not on the list it does not mean we never come — there are dedicated pages for nearly all locations around Glasgow City, and the ones named above are simply the closest neighbours.

On the boundary, or somewhere your phone can't find? Call us and enquire rather than guessing.

Look at our map for the ground covered on this page.

Our technicians work by the road, on forecourts, on driveways and at car parks across all of that, and your vehicle doesn't need to move to us.

## Roadside call-outs in Possil Park

Not everybody gets a safe place to pull in.

Hazards flashing in a lay-by somewhere, or stopped on the verge on Mansion Street because you worked it out after setting off — our technicians take that call so often that it's the usual kind.

Sit with the motor while it is safe to be inside, and out of the vehicle if it's not.

Don't start up the engine to nurse the car somewhere safer — a diesel running on petrol will usually oblige, and every mile it obliges for is pulling that mixture further into the fuel system.

A van coming to a difficult spot is no problem for us, and it is far better for the car than driving on.

Do not risk it. The journey home from The Brothers Bar is entirely possible, which is exactly the issue — a weakened tank does not stop a diesel starting or pulling away, it just wears down the parts your fuel is meant to protect. Call us, then let the BMW 3 Series stay where it is.

## Already run it? Petrol in a diesel after a few miles

Your M8 is the one which matters here, and runs under 3 miles from Possil Park.

Some distance along, and onto it in the first place: a misfuelled diesel will often manage both before anything seems wrong. What you get then is seldom a neat stop. Power falls away, the idle turns uneven, and there may be smoke.

Do not restart it to reposition. Come off at the next sensible exit and turn off.

On a longer run — anything approaching the under 3 miles to the nearest city — take it the petrol has been through the fuel filter, your pump and the injectors, and say so when you call. It affects what our technicians bring.

Here's the whole mechanism. Diesel needs enough body to seal the tight clearances it goes through, and petrol takes that away. That is it. Which explains the usual Brother's Path call — a diesel Nissan Qashqai, out there without a murmur and back down on power, rough at idle, perhaps a bit of smoke. Injection systems work hydraulically as well as chemically, so the fuel has to hold pressure and not just burn; diluted, it escapes past those tolerances instead of building, and delivery comes weaker, later, less even than the motor was built about. Not a failing motor, though. Fuel that has stopped acting like diesel. Put that right and it stops.

## Possil Park itself

Possil Park is a suburban area in Glasgow City, situated near the lakeside and approximately 1.7 miles from Glasgow city centre. Possil Park has a relatively low elevation of 52 metres and is characterised by predominantly flat-type housing. Possil Park is close to nearby places such as Cowlairs, Parkhouse, and Hamiltonhill, and is home to around 5789 residents.

## What our technicians do when our engineers get to you around Possil Park

- The answers alter the work, which is why we ask before quoting: what was put in, how much of that, and if your motor has run.

- The polluted mixture is drawn out of your tank.

- Lines purged, filter cleaned. Whatever is left after that is not the thing that started the problem.

- Clean diesel goes in, and then the fuel system gets bled.

- The engine is started and checked to confirm it runs correctly on new diesel.

That has it ready to pull away.

There's no need for a workshop at any stage, as the work is all done where the car is, and when it's caught soon, long-term damage is very uncommon.

Draining your Ford Focus, changing your filter where there's a usable one, cleaning the fuel lines, putting clean fuel through the entire circuit: that is this job, and it is shaped by the worst of that waiting in the lines instead of in your tank by this point. Three things help when you call from near Possilpoint Community Centre — which side the filler is on, whether a technician can stand beside without blocking the road, and if the motor has run since you filled up. On-street is the usual spot our engineers work, and so the location itself is seldom the problem. A cramped parking bay is better than a car driven somewhere more convenient.

## AdBlue in a diesel tank in Possil Park is a separate problem

The fault isn't the same, though the first rule is — never start it — if what went in was AdBlue rather than petrol.

Petrol thins the diesel and removes the protection the fuel system depends on.

AdBlue is urea dissolved in water, and in a diesel tank it brings rust and deposits in its place.

We deal with both, and AdBlue removal around Possil Park has its own page with the full story — including why it's frequently the more serious of the two.

## What a petrol-in-diesel drain costs around Possil Park

We cannot put one figure on this page truthfully, as this job isn't one job. What moves it:

- Started? Driven? Either answer counts more than anything else on this list.

- The tank's capacity, set against how much of the wrong fuel got into it.

- Whether it's unleaded or AdBlue.

- Where the car is, and if a technician can safely reach and work on it.

Tell us the vehicle, the quantity and if it has run, and you will get a clear answer rather than a range.

Not time-critical, with the car at home and going nowhere? Then  does the job.

Drain it then put fresh diesel in — that's the suggestion you'll get, normally from somebody certain, and it's half right. Do precisely that to a diesel Audi Q5 close to Winners Chapel International and it would start, which is what makes the tip sound reasonable. What takes place next is the issue: the motor at once draws the petrol still sitting in the fuel filter and the feed lines straight back through the pump, as emptying a tank does nothing about fuel that has already left it. Phone us instead. We flush the system and take your filter off where your vehicle has a workable one, which is the difference between the car being repaired and your car just starting.

## Petrol in diesel: everyday questions in Possil Park

## Fuel drains on a Possil Park petrol station forecourt

Plenty of what our engineers do takes place nowhere else. So yes.

Our technicians visit BP and the other forecourts nearby regularly, with the station's permission — tell us which one you're at when you call and we'll tell you if our technicians can work there.

## How much petrol is too much for a diesel?

It rests on the ratio instead of the litres, and far more on whether the motor has run.

What settles how much work is needed is if that mix has been sucked through the system — since though five litres in an almost empty tank is a distinct situation from five in a full one, either way that's the question.

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

Somewhere safe, then stop, then turn off and keep it off.

Driving takes the issue along — out of your tank, into the pump and injectors. Motorists fear it a good deal more than the recovery rate warrants, mind. The one genuinely useful thing left to you is not restarting the car.

## Fuel drains and manufacturer warranties

A drain and flush carried out correctly is not a change and doesn't invalidate a manufacturer's warranty.

What's likelier to start an argument is a diesel that has been run on petrol. One more good reason for the motor to stay off.

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

What petrol has diluted isn't put back by two-stroke oil, which is an old remedy for a separate issue. So no.

The pump still has to cope with it, since that tank still has petrol in it later on.

## A main dealer for petrol in a diesel — needed?

There's no need to bring it to a main dealer, since our engineers drain and flush your car wherever it is.

## You, and the vehicle, still together?

Turned off is how it remains.

Already driven it? Then pull in somewhere sensible, switch off, and let the vehicle stay that way.

This is recoverable from much more regularly than motorists assume, and a still, cold vehicle is the best place to be in.

Clearing misfuelled cars, Possil Park and the rest of Glasgow City, wherever they are. Kerbside. Forecourt. Home.
