# Put Petrol in a Diesel Car in Luncarty? Don't Start It

Don't start the motor. While the fuel is still sitting in that tank and the engine has not yet turned over, a drain is nearly always all it needs — and that is settled in the following few minutes, not by how much was put in. Petrol in Diesel drains and flushes wrongly fuelled vehicles where they are, throughout Luncarty and the rest of Perth and Kinross, on the forecourt, at the roadside or on a driveway.

Our engineers will explain what your next part is. Ring us — this goes ahead of everything else.

## Your next five steps: petrol in a diesel

- Don't fire it up — and do not rely on it when it runs. This is the thing motorists get wrong about petrol in a diesel especially. A petrol motor given diesel generally just can't run, and so the motorist stops and the harm halts with them. A diesel filled with petrol typically starts, idles and pulls away just fine for several miles. It isn't fine. It's wearing the fuel system whenever you drive.

- Diesel burns, and before it combusts it greases — that high-pressure pump, its injectors. Petrol manages only the burning. So leave the car's ignition off also: switching it on is usually enough to prime your system, and priming pulls petrol from your tank into precisely those parts.

- That advice presumes a diesel fuel system tolerates petrol by percentage. It won't. Tip diesel on top and nothing at all is cleared; what you get is a bigger tank of the same mix. And no, the grade makes no difference — super unleaded is still petrol.

- We would much rather travel to an odd location than have it started — so if you safely can, sit tight. Nothing is easier to sort than a motor that has not moved. On the verge on Westfield, that means hazards on and leave the vehicle.

- Have your position ready before you call. A postcode that starts PH1 3 and whatever is closest to you with a sign on it is the difference between the van arriving and the van circling.

- Ring 0333 366 0103. Prepare for three things — what went in, about how many litres, and whether the engine has been turned over. Those replies decide everything that happens next.

Tonight, please, not Monday. Driving it home is the one thing not to do: a commute has put real quantity through your pump already, petrol-thinned diesel and plenty of that, and the return leg would more or less double the figure to no end. The Renault Megane can sit at Perth perfectly safely. Ring from the platform if easier; standing over us while our engineers work is not required.

## Forecourt drains for petrol in a diesel

It begins at a pump, usually. Frequently the work wraps up there as well.

The drain normally happens there and then. Still on the forecourt at BP? Given the station's consent, that's a place our technicians work, and often.

Before your motor has fired — a forecourt is the one setting this gets halted.

The few seconds between checking your receipt and reaching for the key decide how much requires cleaning. Everywhere 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 the tank, through your filter and into your high-pressure pump. That means the lines and the fuel filter need flushing as well as the tank. It's not a calamity, and we can still deal with it where your car stands.

Attendants will generally pitch in pushing it out from the petrol pump, which lets the next motorist get past. Welcome the assistance.

Moving it four bays does not warrant cranking it.

Any start primes your fuel system and pulls more of that mix out of that tank and towards the pump — which is why a car moved twice into a roomier space has silently grown into a bigger job than one left precisely where it stopped. So when our engineers can't work alongside the diesel Volkswagen Tiguan, we shift the vehicle without starting it. None of that is fussiness about a handful of seconds of running. Car parks like the one outside M&S Foodhall we visit frequently, and your fuel is hardly ever the complicated part: that bay is. Motors either side, a trolley shelter behind, at times a height limit at the way in settling whether a technician gets to you at all. Tell us how penned in you are, and which way your car points.

## Luncarty and the villages beside it

Being a village, Luncarty gets a regular call, and its neighbours nearby come with it on that same journey: Redgorton and Stormontfield, Waulkmill and Moneydie, Newmiln.

Not on that list? That says nothing. The places above are just the closest few, and most locations around Perth and Kinross have a page of their own somewhere on our site.

Close to a border, or somewhere a satnav gets wrong? Ring us and enquire instead of presuming.

The map shows the patch this page covers.

Your vehicle does not need to travel to us. We operate across the lot — roadside, forecourts, driveways, car parks.

## Luncarty: stuck where you stopped

Not everybody has a suitable spot to pull in.

Set off, then noticed? Finished up by the verge beside Marshall Way, or parked in some lay-by with your hazards on? That's a common call here. Not an odd one.

Whether you sit by the car or keep clear of it rests on whether being in it feels wise.

Don't start up the motor to limp the vehicle somewhere safer — a diesel running on petrol will frequently oblige, and every mile it obliges for is pulling that mixture further into the system.

We'll send our van to an awkward location without any trouble, and for the car that is a lot better than carrying on.

Park it overnight. Ring us first thing. Nothing about a diesel BMW 1 Series sitting in the parking area outside the pub in the village degrades whilst it sits, tank of petrol or not, and this job remains a simple one right up till the moment it gets driven home. The query we arrive with is about that trip there: a cold engine over a short distance is where petrol burns least well, and whatever fails to burn can get past the piston rings into the engine oil.

## Driven it already? Stop, and check this

Your M90 is the road which matters now, and it lies under 5 miles from Luncarty.

It will often take you onto it, and some way along, before you notice a thing. Then it is smoke, an uneven idle and power falling away — not a tidy stop. Wrongly fuelled diesels rarely give you one of those.

Come off at the first sensible exit, turn off, and don't restart the vehicle to reposition.

Assume the worst of that on a long drive. Anything near the under 5 miles to the closest city, and the contamination has been through the filter, through the pump, through the injectors. Say so when you phone. What we bring alters.

## Where is Luncarty?

Luncarty is a village situated on the banks of the River Tay in Perth and Kinross, with a mix of rural and suburban characteristics. Luncarty lies close to the city of Perth, which is approximately 4 miles away, and is surrounded by other small settlements such as Redgorton and Stormontfield. Luncarty has a population of around 1136 people and is characterised by predominantly detached housing. Luncarty's riverside setting and low elevation of 28 metres contribute to its distinctive landscape.

## When we get to you around Luncarty: what follows

- Three things get checked before any price — your fuel that got in, the amount, and whether anything has been run since. Each answer alters the work.

- Out comes the polluted mixture.

- Our engineers clean the lines and clean the filter, and so what is remaining in the fuel system isn't what caused the trouble.

- Our engineers pour clean diesel in and bleed the system.

- We start it and check it runs properly on fresh diesel.

After that it is ready to drive away.

Long-term damage is very rare when it has been noticed soon, and as all of this is done where the vehicle is, it never needs to be taken to a garage.

## A distinct problem: AdBlue in a diesel tank in Luncarty

The problem is not the same, though the first instruction is — do not crank it — if what went in was AdBlue instead of petrol.

The protection a fuel system depends on gets taken away by petrol, which thins the diesel.

Rust and deposits are what a diesel tank gets instead, because AdBlue is urea dissolved in water.

Our technicians cover both, and AdBlue removal in Luncarty has its own page with the full story — including why it is usually the more serious of the two.

Turn off where you have stopped, and do not start it to find somewhere better — by Milton or anywhere at all. Rattling, an uneven idle, white smoke and a soft throttle are a misfuelled diesel Kia Sportage telling you what is wrong.

## Luncarty costs for a petrol-in-diesel fuel drain

One number would not be honest here, because this isn't one job. These are the things that change it:

- Has it been run or driven? Nothing else counts for as much.

- Wrong fuel in, against what the tank holds — that ratio.

- The type of liquid in the tank, petrol or AdBlue.

- Access: the vehicle's position, and whether working on it there is sensible for a van.

Tell us what your vehicle is, how much got in, and if your motor has run. A straight answer comes back, not a range.

Vehicle at home, going nowhere, nothing pressing about it —  is ideal for that.

Purged, not emptied — that's what a diesel Peugeot 2008 which got as far as Brownlands Park needs. Running a diesel puts that blend into the fuel filter, your lines, your pump and the rail, none of which empties with that tank, and so by now your tank holds the smaller part of the trouble.

## Luncarty motorists ask us these about petrol in diesel

## I am on a forecourt around Luncarty. Can you drain it here?

Yes — forecourts are where a big part of this gets done.

Our engineers visit Gulf and the other forecourts locally all the time, with the owner's consent — tell us which one you are at when you phone and we'll tell you if our technicians can work there.

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

Ratio settles it instead of litres — and more than either, whether the engine has run.

Five litres into an almost dry tank isn't five into a full one, no. But both land on the same question in the end: has that blend been drawn right through, or has it not?

## Already driven it with petrol in the diesel? Now what?

Stop sensibly. Off. Nothing after that.

Driving moves the trouble along — out of that 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 isn't restarting it.

## My warranty — does a fuel drain void it?

A drain and flush carried out correctly is not an alteration and does not cancel a manufacturer's warranty.

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

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

Two-stroke oil solves a distinct issue, and an old one at that. Nothing it does puts back what petrol diluted. No.

Afterwards? Still petrol in your tank, and a pump that has to live with the stuff.

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

No. 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?

Shut off is how it stays.

Already driven it? Then pull in somewhere sensible, turn off, and let the car remain that way.

A stationary, cold vehicle is the best place to be in, and this is recoverable from much more often than people assume.

Call-out fuel draining around Luncarty and throughout Perth and Kinross — at the kerbside, on the forecourt or at home.
