# Winchburgh: Put Petrol in a Diesel Car?

If you have not started the motor as yet, do not. A drain and nothing else is almost always what a motor requires while the fuel is still inside your tank and the motor has not turned over, which is why it's the following few minutes that matter, not how much was put in. Petrol in Diesel comes to the car wherever it has stopped in Winchburgh or the remainder of West Lothian, on the forecourt, by the roadside or on a driveway, and drains and cleans it there.

Our engineers will tell you what your next step will be. Contact us — this comes ahead of everything else.

## What to do first about petrol in a diesel

- Whenever you drive, the pump and your injectors suffer. That's why you never fire it up, and why you do not rely on it once it has started. The catch about petrol in a diesel in particular — the bit motorists get wrong — is that it drives away fine for the first mile or two. Diesel in a petrol engine typically can't run at all, which stops the driver and stops the harm with them. This one lets you carry on.

- Turning the ignition on usually primes the system, and priming is what carries petrol out of your tank and into the pump and injectors. Those are the parts diesel keeps protected on its way through, before it burns. Petrol does the burning and none of the lubricating. Leave the ignition be.

- Do not put diesel on top to dilute it. A diesel fuel system will not handle petrol by percentage as that guidance presumes, and topping up clears nothing — it merely gives you a bigger tank of the same mix. The grade makes no difference either: super unleaded is simply petrol.

- Sit tight if it's sensible to. Hazards on, engine off, keep the car. Wherever you have stopped — the verge on Niddry Road, anywhere — an odd spot for us is better than a started engine, and nothing is quicker for us to handle than a car that never shifted.

- Have your position prepared before you phone. A postcode starting EH52 6 and whatever is next to you with a sign on it is the difference between our van showing up and our van circling.

- Ring 0333 366 0103. Prepare for three queries — what got in, roughly how much, plus if the car has been turned over. The responses settle all that comes after.

Quarter past eight. A rushed fill-up on the drive in. At about eleven it dawns on you, and by then the diesel Volkswagen Passat has waited at Uphall for three hours. Ring us and leave the car where it is. What is key is the run in, as diesel both combusts and — before that — greases the pump and the fuel injectors, while petrol only ever ignites. Those few miles ran your pump on a fuel robbed of most of its protection, and no quantity of standing in a car park gives any of that back. Hence the thing we ask about miles instead of hours sitting, and hence the request to leave your keys where they are till we arrive.

## Removing petrol from your diesel at the forecourt

The work begins at a pump, usually. Frequently the job finishes at one as well.

We work on petrol station forecourts regularly, with the owner's consent, so if you are still at Esso that is normally where this drain takes place.

Before the motor has fired — the forecourt is the only location it ends up halted.

Our technicians can still put it right where it stands, even away from the forecourt. In a car park, on a driveway or in a lay-by, the car has been started and driven there, and that sucked fuel through your filter then into your high-pressure pump, all the way from your tank. None of that is a disaster, but the flush then has to reach past that tank to the fuel lines and the filter, and the few seconds between reading your receipt and reaching for the key are what determine that.

Wheel it out of the way if the staff volunteer, and they normally will. The next driver gets by the petrol pump, and that's worth doing.

Four car lengths is not worth a start.

How much fuel the pump has pulled is what we are really asking — not how long ago any of it was. So the call our technicians like sounds like this: diesel Renault Clio, a couple of litres of unleaded, a couple of miles covered, now switched off at Sainsbury's.

## Do our engineers serve your corner of Winchburgh?

Winchburgh is a coastal village, so our technicians go out to the town and to the villages near it on those same runs: Faucheldean, Woodend, Newton, Broxburn and Threemiletown.

Not on that list? That means nothing. The places above are only the closest few, and the majority of towns around West Lothian have a page of their own somewhere on this site.

Call us to enquire instead of assuming, particularly if you are on the boundary or anywhere a satnav can't find.

The map outlines the area this page spans.

We operate at the roadside, at forecourts, on driveways and in car parks throughout all of it, and your car never needs to travel to us.

Nothing alerts you, because from the driver's seat there's nothing to be warned about. Your diesel Audi A3 will have seemed completely usual on the way back from the local primary school, and they all do — which is the snag with petrol in a diesel instead of the reverse. Diesel in a petrol car generally refuses to run, stopping the motorist and stopping the wear with them. Petrol in a diesel starts, idles, pulls away as though nothing had happened, and all the while the pump works without the protection its fuel is meant to supply. Tell us approximately how far, and how hard. The harder counts more.

## Roadside stops around Winchburgh

Not everybody has a suitable place to pull in.

A routine call for us and not an unusual one: realised after setting off, landed on the verge on Bennet Wood Terrace or at a lay-by with the hazard lights on.

Sit by the motor while it's wise to be in it, but clear of it if it is not.

Don't restart it to reach a better location. It will go — a diesel on petrol normally obliges — and each mile of obliging drags that mixture deeper into the system.

A van heading to a difficult location is no problem for us, and it's much better for the vehicle than carrying on.

It will start. It will drive off just fine. That is the trouble, because a diesel on a weakened tank runs normally while grinding the components its fuel should be lubricating. So no, don't risk the drive home from Tally Ho — leave the BMW 5 Series then call us.

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

This is where your M9 comes into it — under a mile away from Winchburgh.

A drop in power, a rough idle, some smoke: those are the symptoms when they appear, instead of a tidy stop — and a misfilled diesel will usually get you onto it and some way along before anything feels wrong at all.

Take the first exit that is safe, pull up there, and don't restart the car to reposition.

Long drive? Anything approaching the under 10 miles to the nearest city and you should presume the lot — filter, pump, injectors, all of that got to by the contamination. Say that on the phone, because it alters what goes in our van.

Pull in somewhere sensible, turn off and phone us. Normal on the way out to Millgate Wood, gutless on the way back? Then look at the tank. Petrol thins diesel; weaker fuel seeps past the close-fitting parts that build injection pressure; and the further the diesel Ford Kuga went, the less of that pressure it held.

## About Winchburgh

Winchburgh is a coastal village in West Lothian, situated near the Firth of Forth at an elevation of 88 metres. Winchburgh lies within a short distance of several nearby places, including Faucheldean, Woodend, and Newton. Winchburgh has a population of approximately 2205 people, predominantly residing in flats. Winchburgh is located near Dunfermline, the nearest city, which is about 7.7 miles away.

## When our engineers get to you around Winchburgh: what happens

- Three things get established before any quote — the fuel that was put in, the quantity, and whether anything has been run since. Each answer changes the work.

- The tainted fuel comes out of your tank.

- What is left in the system should not be what created the problem, and so the fuel lines get rinsed and your filter cleared.

- Priming follows, once fresh diesel is in.

- Our technicians turn it on and check it runs smoothly on fresh diesel.

Your car is then ready for you to drive away.

There is no need to go to a garage at any point, because the work is all done where the car is, and when it is noticed quickly, long-term damage is very uncommon.

## Winchburgh AdBlue removal is a different job

The fault isn't the same, though the opening rule is — don't start it — if what went in was AdBlue rather than petrol.

The protection a fuel system relies on gets stripped away by petrol, which dilutes your diesel.

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

AdBlue removal in Winchburgh has a page of its own with the details on it, including why it's frequently the more serious of the two. Our technicians cover both.

## Winchburgh pricing for a petrol-in-diesel drain

Frankly, no single figure belongs on a page like this. This job changes. Here's what varies it:

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

- The tank's capacity, set against how much of the wrong fuel went into it.

- Whether it's petrol or AdBlue.

- Where the vehicle is, and if our van can sensibly reach and work on it.

Tell us your vehicle, the quantity and whether it has run, and you'll get a straight answer instead of a range.

For the vehicle at home that's going nowhere and isn't urgent,  works too.

## Petrol in diesel: frequent queries in Winchburgh

## Can you do a fuel drain at a petrol station in Winchburgh?

Much of what our technicians do happens nowhere else. So yes.

Tell us which one you're at when you ring and we will tell you whether we can work there. With the owner's agreement our engineers attend Shell and the other forecourts around town routinely.

## A few litres of petrol in a diesel — too much?

It rests on the proportion instead of the litres, and a lot more on whether the engine 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 settles how much work is required is if that blend has been sucked through the fuel system.

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

Switch off somewhere safe, then keep it that way after you stop.

It's salvageable a lot more regularly than motorists expect, even though driving is what moves the problem from your tank into the pump and injectors — and the single most valuable thing you can do now isn't restart it.

## Fuel drains and manufacturer warranties

A drain and flush carried out correctly is not a modification and doesn't cancel a manufacturer's warranty.

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

## Adding two-stroke oil, then driving home

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

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

## Do I need a main dealer for petrol in a diesel?

There is no need to take it to a main dealer, as we drain and clean your car wherever it is.

## You, and the car, still together?

Shut off is the way it remains.

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

Cold and parked, a motor is in the best place available — and drivers fear this a lot more than the recovery rate warrants.

At the kerbside, on the forecourt or at home — mobile fuel draining in Winchburgh and across West Lothian.
