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

Don't fire up the motor. If the petrol is still in your tank and the motor has not turned over, a drain is almost always all it needs — and that's determined in the following few minutes, not by how much was put in. Petrol in Diesel drains and cleans misfuelled cars where they stand, throughout Uphall Station and the rest of West Lothian, on the forecourt, at the roadside or on a driveway.

Ring us so we can show you what happens next before you attempt much else.

## The next five steps: petrol in a diesel

- Feed a petrol engine diesel and it will typically fail to run at all, so the driver stops there and so does the harm. Give a diesel petrol and the thing starts, it idles, it drives off — fine enough for a few miles. Most people have that reversed, which is the thing they get wrong about petrol in a diesel specifically. So don't fire it up. And once started, don't depend on it: the fuel system is grinding whenever you drive.

- Diesel ignites, and before it combusts it greases — that high-pressure fuel pump, the injectors. Petrol handles only the burning. So leave your ignition alone too: switching it on is usually sufficient to prime your system, and priming draws petrol from your tank into precisely those parts.

- That guidance assumes a diesel fuel system tolerates petrol by percentage. It will not. Put diesel on top and nothing at all is taken out; what you end with is a larger tank of the same mix. And no, the type makes no difference — super unleaded is simply petrol.

- Stay still if it is safe to. Hazards on, engine off, keep it. Wherever you have stopped — the verge on Beechwood Park, anywhere — a tricky spot for us beats a started motor, and nothing is quicker for us to handle than a motor that never shifted.

- A van arriving rather than circling depends on two things: a postcode beginning EH54 5, and whatever is nearest to you with a name on it. Keep both prepared before you phone.

- Call 0333 366 0103. Prepare for three queries — what was put in, roughly how much, and whether the engine has been started. Your answers determine everything that happens next.

## Pump-side draining for petrol in a diesel

A large part of the job gets done at the pump, since that is where it often kicks off.

If you are still on the forecourt at BP, that's usually where the drain takes place — our technicians work on garage forecourts routinely, with the station's consent.

At a garage, this gets stopped with your engine never run, and nowhere else manages that.

Fuel pulled out of your tank and through the filter, right to the high-pressure pump, is what happens when your engine 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 takes in the fuel filter and the fuel lines along with your tank. That is still not a disaster, and our engineers deal with it where the vehicle stands. What determines it is whether the ignition was turned in the seconds after your receipt was read.

Clear of the petrol pump, the next driver can get through — so yes, let the staff help you wheel the vehicle. Very much worth doing.

Four vehicle lengths isn't worth the risk.

How much fuel the pump has drawn is what we are actually asking — not how long ago any of that was. So the phone call we like goes like this: diesel Renault Megane, some litres of unleaded, a couple of miles covered, now switched off at Aldi.

## Uphall Station and the places next to it

The same runs carry us to Pumpherston, Uphall, Upper Uphall, Craigshill and Broxburn along with Uphall Station, which is a small village.

If yours is not on this list it does not mean we never come — there are pages for the majority of towns in West Lothian, and the ones named above are simply the immediate neighbours.

Call us and enquire instead of guessing — county lines particularly, and wherever the satnav can misread.

The map marks the ground the page spans.

We work at the roadside, at forecourts, on driveways and in car parks over all of that, and the car never needs to move to us.

Move it out of that gateway and deal with it later — that is what a passer-by will say, and it's wrong. Parked on the zig-zags at the local primary school, a misfuelled diesel BMW 3 Series is a nuisance and nothing worse. Started three more times for courtesy, it's no longer a tank fault but a fuel system one, as priming happens with every start and more petrol goes through your filter on to the pump. Let people moan. Ring us.

## Roadside breakdowns around Uphall Station

Some drivers find no safe place to pull in at all.

A routine call for us rather than an unusual one: realised after setting off, landed on the verge beside James Young Avenue or in a lay-by with the hazard lights flashing.

Clear of the car while it isn't safe to be inside, by it if it is.

Do not start it up to reach a nicer location. It'll go — a diesel on petrol generally obliges — and each mile of obliging draws the mixture deeper into your fuel system.

Carrying on does the vehicle far more harm than a technician heading out to an inconvenient spot, and that is no problem for us.

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

Your M8 is the one which matters here, and it lies under a mile from Uphall Station.

Some distance along, and onto it in the first place: a misfilled diesel will usually manage both before anything feels wrong. What you get then is rarely a neat stop. Power ebbs away, the idle gets lumpy, and there may be some smoke.

Do not restart it to reposition. Pull off at the next safe junction then switch off.

It alters what we bring, so say so when you phone: on a longer trip — anything close to the under 15 miles to the nearest city — take it the contamination has been through the fuel filter, the pump and the fuel injectors.

Out there happy, back sluggish. If that was the drive to Houston Driving Range, look at your tank. Diesel gets thinned by petrol, and thin fuel seeps past the tight gaps supposed to build injection pressure — so every additional mile your diesel Mercedes C-Class covered, the less pressure it held onto. Somewhere sensible, turn off, phone us.

## Uphall Station itself

Uphall Station is a small locality in West Lothian, situated near the River Almond and close to the villages of Pumpherston and Uphall. Uphall Station sits at an elevation of 116 metres, with detached housing being the predominant type of accommodation in the area. Uphall Station is located near the town of Broxburn and the city of Dunfermline, which is approximately 10.6 miles away.

## What comes next when our engineers arrive with you in Uphall Station

- We check what was put in, how much, and if your motor has run. The replies change the work, which is why our technicians ask before giving a price.

- The tainted fuel is pulled from your tank.

- Our technicians purge your fuel lines and clear the filter, and so what is remaining in your system is not what started the issue.

- Priming follows, once clean diesel is in.

- It is run with fresh diesel in it, and our technicians check that it is running correctly.

Then it is ready to drive away.

Permanent damage is very rare when it has been noticed soon, and since all of this is done where the vehicle is, it never has to go to a garage.

## Uphall Station AdBlue removal is a different job

Do not fire it up: that first rule stands whether what went in was AdBlue or petrol. What differs is this fault itself.

Petrol weakens the diesel and strips the lubrication your fuel system depends on.

AdBlue is urea in water, and in a diesel tank it brings rust and residue instead.

We deal with both, and AdBlue removal around Uphall Station has its own page with the full story — including why it is frequently the more significant of the two.

Switch off where you have stopped, and don't start it to find somewhere better — close to Uphall Station Bowling Pavilion or anywhere at all. Knocking, a lumpy idle, white smoke and a soft throttle are a misfuelled diesel Vauxhall Astra telling you what is wrong.

## Budgeting for a petrol-in-diesel fuel drain in Uphall Station

One figure would not be honest here, since this is not one job. These are the things that move it:

- This is the key one: whether the engine has been run, or driven.

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

- AdBlue or unleaded, whichever went in.

- Access: the car's position, and if working on it there's safe for our van.

A firm answer instead of a range is what you get for telling us three things: the vehicle, the quantity, and whether it has run.

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

A couple of streets, then it stopped. Throttle dead, idle lumpy, and your diesel Kia Sportage is parked up near Uphall Station Village Community Hub. The engine isn't giving up — that softness is fuel that won't build pressure. There is no light on the dash for it, so cars like yours typically get driven again before anybody picks up the phone. Do not. Off, then ring us.

## Petrol in diesel questions from Uphall Station motorists

## Fuel drains on a Uphall Station petrol station forecourt

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

We attend Shell and the other forecourts locally routinely, with the owner's permission — tell us which one you're at when you phone and we will tell you whether we can work there.

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

Proportion decides it rather than litres — and more than either, whether the motor has run.

Five litres in a nearly empty tank is a separate matter from five in a full one — but either way, the thing that decides how much work is needed is if that mix has been pulled through the fuel system.

## Petrol in my diesel, and I have driven the car

Somewhere safe, then stop, then switch off and leave it off.

Driving moves the problem along — out of your tank, into your pump and injectors. People fear it a good deal more than the recovery rate warrants, mind. The one truly useful thing left to you isn't restarting the vehicle.

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

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

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

## Two-stroke oil in that tank, and then home?

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

That tank still has petrol in it afterwards, and the pump still has to live with it.

## Main dealers and petrol in a diesel

There is no need to take it to a franchised dealer, as our technicians drain and clean your car wherever it is.

## Standing next to it?

Keep the engine shut off.

If you have already driven the car, pull in somewhere sensible, switch it off then leave it off.

This is recoverable from a lot more commonly than motorists assume, and a stationary, cold vehicle is the best position to be in.
