# Stonelaw Dale: Put Petrol in a Diesel Car?

With that tank still holding the fuel and your engine not yet turned over, almost every job takes only a drain, so leave your engine off. That result is settled in the minutes right after the fill-up, rather than by the amount that went in. Across Stonelaw Dale and the rest of Northumberland, Petrol in Diesel drains your car and cleans it where it stands, whether by a roadside, on a private drive or at a forecourt.

A single ring our way is plenty: our engineers shall tell you what comes next. Do it first.

## Petrol in a diesel: what to try next

- Do not fire it up — and never rely on it when it fires up. That is the thing most people get wrong about petrol in a diesel especially. A petrol motor given diesel usually just won't run, and so the motorist stops and the damage ends with them. A diesel given petrol generally starts, ticks over and moves off just fine for a few miles. It's not all right. It's wearing out your fuel system while you drive.

- Diesel burns, and before it ignites it lubricates — the high-pressure fuel pump, those injectors. Petrol manages only the burning. So leave your ignition off too: flicking it on is often enough to prime your system, and priming draws petrol from the tank into exactly those components.

- Never pour diesel on top to weaken it. A diesel fuel system doesn't accept petrol by percentage the way that advice presumes, and topping up takes out nothing — it simply gives you a larger tank of the same mixture. The type makes no difference either: super unleaded is still petrol.

- Sit tight if it is safe to. Hazards on, engine off, keep it. Wherever you have stopped — the verge on Monkside, anywhere — an odd spot for us beats a started diesel, and nothing is quicker for us to handle than a vehicle that never shifted.

- Before you phone, get your location. Anything next to you with a name on it, plus a postcode that starts NE23 6 — that's what settles whether the technician turns up or circles.

- Phone 0333 366 0103. Say what was put in, roughly how many litres, and also if the engine has run. Those three replies settle the entire visit.

The high-pressure pump did that morning drive running on a fluid that had given up most of the protection it is made for. Diesel greases that pump, and the fuel injectors with it, before any of your fuel burns; petrol does the burning and none of the lubricating. So picture a diesel Renault Megane, fuelled at quarter past eight, driven in to work, and parked standing at Cramlington till you realise at about eleven. Three hours of sitting have changed nothing about it. The few miles before that did a lot, which is why the question we ask you is about mileage not time. Call us. Leave the vehicle precisely where it stands.

## Clearing petrol from the diesel on the forecourt

It kicks off at the pump, usually. Often enough it ends at one as well.

Still at Sainsbury's? Then that is generally where it gets done. Station forecourts are everyday for us, with the agreement of the owner.

Nowhere but the forecourt can the mistake be caught with the motor still cold.

The few seconds between checking the till receipt and reaching for the keys decide how much requires flushing. Everywhere other than the forecourt — a car park, a driveway, a lay-by — the vehicle was fired up and moved to get there, so fuel was pulled from your tank, through your filter then into your high-pressure pump. That means the lines and the fuel filter require cleaning as well as the tank. It is not a calamity, and our technicians can still deal with it where the car stands.

Roll the vehicle out of the way if the attendants offer, and they normally will. The next driver gets past the petrol pump, and that is worth doing.

Cranking it just for four car lengths? No.

Simple, these ones, and the reason is the distance: a mile at easy throttle draws hardly any of it. Petrol into a diesel Volkswagen Passat somewhere around Stonelaw Dale, a boot packed with shopping, and you sat at M&S Foodhall — phone. Exiting the space isn't worth a restart. Your tank gets drained where it sits, the fuel lines flushed, new diesel in, and you head home.

## Do our technicians cover your part of Stonelaw Dale?

Stonelaw Dale is a residential suburb, and so we head out to the town and to the areas around it on those same rounds: Whitelea Chase, Stonelaw Grange, Whitelea Glade, Whitelea Dale and Hall Close Chase.

There are pages for nearly all places in Northumberland, and the ones listed above are simply the immediate neighbours — so yours being absent from that list tells you nothing at all about whether our engineers come.

Phone to ask rather than guessing, above all where you are on a border or somewhere your phone misreads.

This map is the area the page includes.

The lot is territory our technicians serve: a kerbside, a forecourt, a drive, a car park. You don't move the car anywhere.

## Stuck at the kerbside around Stonelaw Dale

Some drivers get no sensible spot to pull in whatsoever.

Hazards going in a lay-by somewhere, or stopped on the verge of Lancastrian Road since you noticed after setting off — our engineers take that call so often that it is the normal kind.

Whether you sit with the motor or step clear of it hangs on if staying nearby looks wise.

It will usually oblige. A diesel running on petrol limps along very willingly, and that is the catch: fire it up to get to somewhere better and the blend goes further into your fuel system with every mile travelled.

However inconvenient the spot, it's no trouble for us to come to it, and that is a lot better for the vehicle than driving on.

Your Dacia Duster remains where it is in the car park at Lord of the Manor for the whole job, which generally runs like this. First our technicians ask what went in, roughly how much, and whether the motor has run since, because most of the work rests on those replies. That tank is emptied of the contaminated mix, your lines are rinsed, and the filter comes off if it's a replaceable one. With clean diesel in and the system primed, the vehicle is started and checked, and once it's running correctly you pull away.

## Driven it already? Pull over, and see below

under 10 miles from Stonelaw Dale, your A167(M) is what matters now.

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

Come off at the first sensible junction, switch off, and don't start the vehicle to move it.

It affects what we bring, so mention it when you phone: on a longer trip — anything approaching the under 10 miles to the closest city — assume the petrol has been through your filter, the pump and your injectors.

## Where's Stonelaw Dale?

Stonelaw Dale is a suburban area located inland in Northumberland, approximately 7 miles from Newcastle upon Tyne. Stonelaw Dale sits at an elevation of 66 metres, surrounded by other residential areas such as Whitelea Chase and Stonelaw Grange. Stonelaw Dale has a population of around 2183 people, predominantly living in semi-detached housing. Stonelaw Dale is part of the wider Newcastle upon Tyne urban area, with easy access to the city's amenities.

## Our visit in Stonelaw Dale, step by step

- We check what went in, how much, and if your engine has run. The responses change the work, which is why we ask before quoting.

- That tank gets drained of everything.

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

- Priming follows, once fresh diesel is in.

- It's started with new diesel in it, and we make sure that it's running smoothly.

That leaves the car ready to set off.

Permanent damage is very rare when it has been spotted soon, and as all of this is done where your car is, it never needs to go to a garage.

Draining the Vauxhall Astra, changing the fuel filter where there's a serviceable one, purging the fuel lines, putting clean fuel through the full circuit: that is this job, and it's shaped by the worst of it resting in the lines rather than in your tank by this point. Three things help when you call from close to Alexandra Park Pavilion — which side the filler is on, whether a van can stand alongside without blocking the road, and whether the engine has run since you filled up. On-street is the most common location we work, so the place itself is hardly ever the problem. A cramped parking bay is better than a vehicle driven somewhere more convenient.

## Stonelaw Dale AdBlue removal is a distinct matter

AdBlue rather than petrol? Then the opening rule is unchanged — your engine stays off — whereas this problem underneath it's a different one altogether.

Petrol does two things to diesel: thins it, and takes away the protection the system relies on.

AdBlue is urea in water, and in a diesel tank it leads to rust and deposits instead.

Usually the more significant of the two, AdBlue — and the detail sits on its own Stonelaw Dale page. Both are ours to deal with.

## Stonelaw Dale prices for a petrol-in-diesel fuel drain

One figure wouldn't be fair here, since this is not one job. These are the things that move it:

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

- How much of the wrong fuel went in, against how much that tank holds.

- AdBlue or unleaded, whichever got in.

- Where your car is, and if a technician can sensibly get to and work on it.

Tell us the vehicle, the quantity and if it has run, and you will get a firm answer instead of a range.

Not urgent, with the vehicle at home and going nowhere? Then  is fine.

A couple of streets, then it stopped. Throttle soft, idle ragged, and your diesel Skoda Superb is parked up near Cramlington Library. Your engine isn't failing — that sluggishness is fuel that will not build pressure. There's no light on the dash for it, and so vehicles like yours usually get driven once more before anyone picks up the phone. Do not. Off, then call us.

## Petrol in diesel queries from Stonelaw Dale motorists

## At a petrol station around Stonelaw Dale, can you do a fuel drain there?

A big portion of this work takes place there, so yes.

We visit Co-op Food and the other forecourts nearby all the time, with the station's consent — tell us which one you are at when you call and we'll tell you if we can work there.

## Is there a sensible amount of petrol in a diesel?

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

A nearly empty tank with five litres in it, against a full one with the same five: different situations, definitely. Either way, the work required comes down to one thing, which is if the system has had that blend sucked through it.

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

Stop sensibly. Off. Nothing after that.

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

## Is a fuel drain going to void my warranty?

A manufacturer's warranty outlasts a drain and flush done to a proper standard, which is no modification at all.

Running a diesel on petrol is the thing more likely to cause a dispute with one, which is another reason to leave the car turned off.

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

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

Petrol stays in that tank later, whatever else goes in, and the pump gets no break from it.

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

There is no need to bring it to a main dealer, because our technicians drain and clean the vehicle wherever it is.

## You, and your vehicle, still together?

Switched off is the way it remains.

If you have already driven it, pull over somewhere safe, turn it off and leave it off.

Cold, parked, going nowhere: that is the best place to be in. People fear this much more than they need to.

At the kerbside, on the forecourt or at home — mobile fuel draining around Stonelaw Dale and throughout Northumberland.
