# Pilrig: Put Petrol in a Diesel Car?

Petrol in Diesel drains and flushes wrong-fuelled cars where they sit, on the forecourt, by the roadside or on a driveway, throughout Pilrig and the rest of City of Edinburgh. The very first thing to do is not to start the engine. While your engine has not yet run and the petrol is still in your tank, a fuel drain is almost always all it needs, and the next few minutes settle that, not how much went in.

A single ring to us is enough: our team shall show you what happens next. Make that straight away.

## Petrol in a diesel: what to try first

- Feed a petrol engine diesel and it will normally fail to run at all, and so the driver stops there and so does the damage. Feed a diesel petrol and the thing starts, it idles, it pulls away — fine enough for a couple of miles. People have that reversed, which is the thing they get wrong about petrol in a diesel in particular. So don't fire it up. And once started, do not believe it: your fuel system is wearing as you drive.

- Diesel ignites, and before it combusts it lubricates — your injection pump, its injectors. Petrol manages only the burning. So leave the ignition off too: flicking it on is frequently sufficient to prime your system, and priming moves petrol from your tank into exactly those parts.

- Don't weaken it. Diesel put on top gets rid of nothing, so all you have is more of what was already there, since percentage is not how a diesel fuel system copes with petrol. Super unleaded? Simply petrol. The type makes no difference.

- Stay put if it is sensible to. Hazards on, ignition off, leave it. Wherever you have stopped — the verge on Pilrig Street, anywhere — an awkward location for us beats a started motor, and nothing is easier for us to sort out than a car that never shifted.

- Have your position ready before you phone. A postcode that starts EH6 5 and whatever is nearest to you with a sign on it is the difference between our van showing up and the van circling.

- What got in, approximately how much, and also if your car has started — the three details determine the full visit. Dial 0333 366 0103 then tell us.

Nothing about the hours since has cost you anything. Fuel in a tank is dormant, and so a diesel Volkswagen Golf parked at Edinburgh Waverley this morning is no worse at five than it was at nine — what pulled diluted diesel through the pump was the drive in. Phone us before you go to collect the vehicle.

## Can petrol be taken out of a diesel at the forecourt?

Pumps are where the job usually begins, and where a big part of that closes.

Still at BP? Then that's normally where it happens. Petrol station forecourts are everyday for us, with the consent of the site.

Nowhere other than a forecourt can the mistake be halted with the engine still unrun.

Fuel sucked out of your tank and through the filter, all the way to your high-pressure pump, is what happens when the engine is switched on and the car is moved to where it is now: the car park, the drive or the lay-by, anywhere other than the forecourt. So the flush takes in the fuel filter and the lines together with that tank. That's still not a calamity, and our technicians sort it out where your car stands. What decides it is whether the key was reached for in the seconds after the receipt was checked.

Staff will normally chip in pushing it away from the petrol pump, which lets the next motorist get by. Accept the offer.

Four car lengths isn't worth the risk.

Car parks like the one at Scotmid are somewhere we attend often, and the fuel is seldom the difficult part. The bay is: motors either side, a trolley shelter behind, occasionally a height bar on the way in that determines if a technician can reach you at all. So tell us how boxed in you are when you call, and which way your car is facing. When we can't work next to your diesel Renault Clio we will move the vehicle without starting it — and that is not fussiness about a few seconds of running. Each start primes your fuel system and draws more of that blend out of your tank and on to your pump, so a motor shunted twice into a roomier spot has gradually become a harder job than one left just where it stopped.

## Pilrig and the towns next to it

These same runs get us to Bonnington, Broughton, Hillside, Leith and Greenside besides Pilrig, which is a residential suburb.

We do come. The places above are just the closest neighbours, and a page is there for nearly all places in City of Edinburgh, and so an absence from the list is not an absence from the coverage.

Guessing is the mistake to skip, especially on a border or somewhere the satnav fails. Ring us to check.

That map is the patch this page includes.

Our technicians work by the road, at forecourts, on driveways and in car parks throughout all of it, and the vehicle does not need to come to us.

Nothing alerts you, since from the driver's seat there's nothing to be warned about. The diesel Skoda Octavia will have felt entirely ordinary on the way back from the local primary school, and they all do — which is the snag with petrol in a diesel rather than the reverse. Diesel in a petrol vehicle usually refuses to run, stopping the motorist and stopping the damage with them. Petrol in a diesel fires up, idles, pulls away as though nothing had happened, and all the while the pump does its work without the lubrication its fuel is meant to supply. Tell us roughly how far, and how hard. The harder counts more.

## Broken down at the kerbside near Pilrig

The chance to pull over somewhere sensible does not come to everyone.

If you realised after setting off and ended up along the verge beside Rosslyn Terrace, or at a lay-by somewhere with the hazard lights on, that's a normal call for us instead of an unusual one.

Safe there? Wait by it. Not fine? Move out and away from it.

Never start it up to get to a better location. It will go — a diesel on petrol generally obliges — and each mile of obliging draws the blend deeper into the fuel system.

However awkward the place, it is no bother for us to come to it, and that is much better for the vehicle than driving on.

What our technicians will want to know is whether the run there was short and chilly, as that is where petrol is least able to burn correctly — and anything that does not burn can work past the rings and into the engine oil. Right up to the moment somebody drives it home, a diesel BMW 3 Series standing in the car park by The Harp & Castle with a tank full of petrol in it is a straightforward job. Nothing degrades as it stands, and so park the vehicle overnight and phone next morning.

## Already driven it? Petrol in a diesel after some miles

The M8 is the road which matters now, and it sits under 10 miles from Pilrig.

A wrongly fuelled diesel will frequently get you onto it and some way along before anything seems wrong, and the signs when they arrive are typically lost power, an uneven idle and smoke rather than a neat stop.

Take the first junction that is sensible, stop there, and do not start the car to reposition.

It affects what our technicians bring, and so mention it when you ring: on a longer drive — anything approaching the under 3 miles to the nearest city — assume the contamination has been through the filter, the pump and your injectors.

Pull over somewhere safe, turn off and ring us. Normal on the way out to Pilrig Park Community Woodland, gutless on the way back? Then look at the tank. Petrol dilutes diesel; thinner fuel slips past the tightly fitted components that build injection pressure; and the farther your diesel Dacia Duster travelled, the less of that pressure it held.

## A little about Pilrig

Pilrig is a suburban area in the City of Edinburgh, situated approximately 1 mile from Edinburgh city centre. Pilrig occupies a coastal location, with an elevation of around 17 metres, and is characterised by predominantly flat-type housing. Pilrig is close to nearby places such as Bonnington, Broughton, and Hillside, and is home to a population of around 17,738 people.

## What comes next when our technicians reach you in Pilrig

- Our technicians check what got in, how much, and if your motor has run. The replies alter the work, which is why we ask before pricing.

- Out flows the polluted fuel.

- What is left in the fuel system shouldn't be what caused the issue, so the fuel lines get purged and the filter cleaned.

- Priming follows, once fresh diesel is in.

- The engine is turned on and tested to be sure it runs properly on clean diesel.

That leaves it ready to drive away.

Everything is done where the vehicle is, so it never needs to be taken to a garage, and when it has been spotted early, long-term damage is very uncommon.

## AdBlue in a diesel tank around Pilrig is a different problem

Don't fire it up: that first step applies whether what was put in was AdBlue or petrol. What differs is the issue itself.

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

AdBlue is urea dissolved in water, and in a diesel tank it leads to rust and build-up in its place.

Frequently the more significant of the two, AdBlue — and the detail sits on its own Pilrig page. Both are ours to handle.

## What a petrol-in-diesel drain costs in Pilrig

What changes the figure is listed below, because this job is not one job and we can't honestly put a single price 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.

- Whether it is petrol or AdBlue.

- Where is it? And can a technician reach it and work there sensibly?

The car, the quantity, whether it has run — give us those and the answer comes back clear and not as a range.

If it's not pressing — the vehicle is at home and going nowhere —  works too.

## Petrol in diesel: frequent queries in Pilrig

## I am on a forecourt around Pilrig. Can you drain the vehicle on the spot?

Yes — forecourts are where a good share of this takes place.

Tell us which one you are at when you call and we'll tell you whether our technicians can work there. With the site's permission we work at another forecourt nearby and the other forecourts nearby routinely.

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

It hinges on the proportion instead of the litres, and much more on whether your engine has run.

An almost empty tank with five litres in it, against a full one with the same five: different scenarios, certainly. Either way, the work required comes down to one thing, which is if the system has had that mix drawn through it.

## Already driven it with petrol in the diesel? What then?

Stop somewhere sensible, turn off, and keep the vehicle off.

It's salvageable far more frequently than drivers assume, even though driving is what takes the trouble from your tank into the pump and injectors — and the single most useful thing you can do now is not restart it.

## Will a fuel drain void my warranty?

No. Carried out correctly, emptying and flushing is no alteration at all, and the warranty from your manufacturer is unaffected by it.

Running a diesel on petrol is the thing likelier to cause a disagreement with one, which is another reason to leave it switched off.

## Adding two-stroke oil, then driving home

Two-stroke oil solves a different fault, and an old one at that. Nothing it does puts back what petrol weakened. No.

After that? Still petrol in the tank, and a pump that has to put up with the stuff.

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

Not at all. Our engineers drain and clean the car wherever it is, so there is no need to take it to a main dealer.

## Standing next to it?

The engine remains off.

Driven it already? Then somewhere sensible, stop, switch off, and no restarting it after that.

A parked, cold car is the best position to be in, and this is recoverable from far more commonly than motorists assume.

Mobile fuel draining in Pilrig and throughout City of Edinburgh — at the roadside, on the forecourt or at home.
