# West Boldon: Put Petrol in a Diesel Car?

If you have not started the engine yet, do not. A fuel drain and nothing else is almost always what a motor requires while the fuel is still inside the tank and the motor has not yet been started, which is why it's the next few minutes that count, not how much was put in. Petrol in Diesel travels to the vehicle wherever it has stopped in West Boldon or the remainder of Tyne and Wear, on the forecourt, by the roadside or on a drive, and drains and cleans it there.

Call us so our team shall tell you what happens from here before you try any more.

## What to try now about petrol in a diesel

- Whenever you drive, your pump and the injectors wear down. That is why you do not start it, and why you do not depend on it once it has started. The catch about petrol in a diesel in particular — the bit people get wrong — is that it pulls away fine for the first mile or two. Diesel in a petrol engine usually can't run at all, which stops the driver and stops the wear with them. This one lets you carry on.

- Diesel ignites, and before it combusts it protects — that injection pump, its injectors. Petrol does only the burning. So leave your ignition be also: switching it on is usually enough to prime your system, and priming pulls petrol from the tank into just those components.

- Don't weaken it. Diesel put on top clears nothing, and so all you get is more of what was already there, since percentage isn't how a diesel fuel system copes with petrol. Super unleaded? Still petrol. The grade makes no difference.

- A motor that has not shifted is the quickest one to sort, so stay where you are if you safely can. Stopped on the verge on Rosemount Court? Hazards on, then keep the car there. A tricky spot suits us better than a started engine.

- Before you ring, get your position. Anything closest to you with a name on it, plus a postcode beginning NE36 0 — that's what determines whether our van turns up or circles.

- Ring 0333 366 0103. Prepare for three things — what was put in, roughly how much, plus if the engine has been started. The responses shape everything that comes after.

Never take it home. Petrol-thinned diesel has passed through your high-pressure pump in real quantity on the road in, and the drive back would about double that for nothing at all. Ring us — the platform is fine. There's no need to stand over your Volkswagen Golf at East Boldon while the work goes on, and we'd far rather talk to you tonight than find out on Monday.

## Clearing petrol from your diesel on a forecourt

Plenty of the job starts at a forecourt, meaning a large part of that is finished at one.

We work on petrol station forecourts routinely, with the station's permission, and so if you're still at Asda that's typically where the drain takes place.

A filling station is the one setting it can be spotted before your motor has started.

The few seconds between checking the receipt and reaching for the key decide how much needs rinsing. Everywhere other than the forecourt — a car park, a drive, a lay-by — the vehicle was fired up and moved to get there, so fuel was pulled from that tank, through the fuel filter then into your high-pressure pump. That means the lines and the filter need cleaning as well as your tank. It's not a calamity, and our technicians can still deal with it where the car sits.

Clear of the petrol pump, the next motorist can get past — so yes, let the staff help you move it. Very much worth doing.

Four vehicle lengths isn't worth the risk.

## Coverage in West Boldon

West Boldon is a village, so our technicians go out to the town and to the places by it on the same trips: East Boldon, Boldon Colliery, Downhill, Town End Farm and Hylton Red House.

There are separate pages for the majority of towns around Tyne and Wear, and the ones mentioned above are just the immediate neighbours — so yours being left off this list tells you nothing about if our engineers come.

Ring us to check instead of presuming, above all if you are on a boundary or somewhere a satnav struggles with.

Look at our map for the area shown here.

We work by the road, at forecourts, on driveways and in car parks throughout all of it, and your car doesn't need to move to us.

How far, and how hard? The second of those counts more than the first, and so have both ready. Your Audi A4 will have seemed completely ordinary on the way back from West Boldon Primary School — they all do, and that is the catch. Diesel into a petrol car usually won't run at all: the person stops, and so does the damage. Petrol into a diesel starts, idles, moves off like nothing happened, whilst the high-pressure fuel pump gets on with its work minus the protection the fuel should be giving it. No warning appears, because behind the wheel nothing seems wrong.

## Kerbside stops across West Boldon

A chance to stop anywhere suitable does not come to everybody.

If you noticed after setting off and finished up on the verge on Aviemore Road, or in a lay-by somewhere with the hazard lights flashing, that's a routine call for us and not an unusual one.

Okay where you are? Sit by it. Not safe? Step out and clear of it.

Every mile a diesel obliges you for on petrol drags that mix further into your fuel system — and oblige it often will, which is why your engine doesn't get restarted to limp somewhere handier.

Our van driving to a difficult spot is no bother for us, and it's far better for the vehicle than carrying on.

## Petrol in a diesel, and the vehicle has moved

under 3 miles out of West Boldon, the local A194(M) is what matters here.

It will usually take you onto it, and some way along, before you spot a thing. Then it is smoke, a lumpy idle and power falling away — not a clean stop. Misfuelled diesels seldom give you one of those.

The next safe junction is the one to take. Switch off there, then leave the restarting alone.

Long drive? Anything approaching the under 5 miles to the nearest city and you should suppose the lot — filter, pump, injectors, all of that reached by the petrol. Say that on the call, because it alters what goes in our van.

None of it is the engine failing. That is the part worth hearing, and it's why the normal Boldon Golf Club call ends better than it sounds: a diesel Vauxhall Astra drives out there without complaint, comes back with the power gone, the idle lumpy and possibly a little smoke, and the cause is your fuel no longer behaving like diesel. Diesel has to be heavy enough to seal the tightly fitted parts it runs through; petrol dilutes it; and a diesel injection system is hydraulic as much as chemical, needing the fuel to hold pressure and not only to burn. So pressure that should build then stay built bleeds past gaps, delivery turns up poorer and later and less even than designed, and all of that stops once the fuel is sorted.

## A little about West Boldon

West Boldon is a village situated on the banks of the River Wear in Tyne and Wear, with a mix of semi-detached housing and local amenities. West Boldon lies close to the city of Sunderland, approximately 3.7 miles away, and is near other settlements such as East Boldon and Boldon Colliery. West Boldon has a relatively low elevation of around 51 metres above sea level, typical of the coastal lowlands of the North East region. West Boldon is also within a short distance of other nearby places, including Downhill.

## What comes next when our engineers reach you around West Boldon

- Our engineers ask first, quote after. What went in? How much? Has the motor run? Those answers alter what the work really is.

- Away flows the contaminated fuel.

- Fuel lines are flushed through and your filter cleared, leaving nothing in the system that started any of this.

- Priming follows, once new diesel is in.

- The motor is turned on and tested to be sure it runs properly on fresh diesel.

Your car is then ready for you to pull away.

Our engineers do all of it wherever your car has ended up, which means it never has to be taken to a workshop, and if it has been noticed soon, it's very uncommon for there to be long-term damage.

Why so direct about leaving the keys alone? Since the pump is before the fuel injectors, and a wearing one sends whatever it loses downstream with the fuel. Ring us. Leave the Ford Kuga by Boldon Lawn Tennis Club.

## AdBlue in a diesel tank around West Boldon is a different job

The problem isn't the same, though the opening instruction is — don't crank it — if what was put in was AdBlue rather than petrol.

Diluted diesel, and no lubrication left for your fuel system that relies on it. That is petrol.

AdBlue is urea dissolved in water, and in a diesel tank it leads to corrosion and deposits in its place.

AdBlue removal in West Boldon has a page of its own with the detail on it, including why it's usually the more significant of the two. Our technicians cover both.

## What a petrol-in-diesel drain will cost in West Boldon

One figure wouldn't be honest here, as this isn't one job. These are the things that change it:

- This is the key one: whether your motor has been started, or driven.

- Wrong fuel in, against what that tank takes — that proportion.

- Which was put in: petrol or AdBlue.

- Whether our van can safely get to your car and work on it, which rests on where your car is.

Tell us your car, the quantity and whether it has run, and you will get a straight answer rather than a range.

For your car at home that's going nowhere and is not pressing,  is fine too.

No warning light exists for this, which is why vehicles in that position usually get driven again before somebody calls. Please don't be one of them. The throttle went soft and your idle turned lumpy after a few streets, and the diesel Volvo XC60 is now waiting near East Boldon Methodist Church. Deadness there means fuel that can't build pressure properly instead of a motor giving up. Turn off. Call us.

## Things our technicians hear about petrol in diesel in West Boldon

## Fuel drains on a West Boldon petrol station forecourt

A fair portion of this work happens there, so yes.

Agreement from the site is the condition. Given that, a forecourt like Shell is somewhere we're regularly, along with the rest of them locally — so name yours on the phone and you will hear whether working there's possible.

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

It rests on the proportion rather than the litres, and much more on whether the motor has run.

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

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

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

Driving moves the problem along — out of that tank, into your pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one really helpful thing left to you is not restarting the vehicle.

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

A manufacturer's warranty withstands a drain then flush done to a correct standard, which is no alteration at all.

What's likelier to start a disagreement is a diesel that has been run on petrol. One more reason for your engine to remain off.

## Adding two-stroke oil, then driving home

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

The tank still has petrol in it after that, and the pump still has to put up with it.

## Main dealers and petrol in a diesel

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?

Keep it switched off.

Turn it off somewhere safe and keep it off, if you have already driven it.

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

Clearing wrongly fuelled cars, West Boldon and the rest of Tyne and Wear, wherever they are. Kerbside. Forecourt. Home.
