# Lindale: Petrol in a Diesel Car? How Worried to Be

Not started? Then less anxious than you probably are.

Until the ignition primes your pump, the starter cranks, or the vehicle is driven, petrol in a diesel tank just waits there and does nothing. Which means the honest reply to the first Lindale question — "have I wrecked it?" — usually no.

Petrol in Diesel is who to phone, with your engine left off, and so it remains that way.

The rest of this page explains what petrol really does to a diesel, how to tell how far it has got, and how to make sure it doesn't happen to you again.

## The motor and petrol in a diesel: what happens

On its way through an engine, diesel has two tasks.

It lubricates first, and only then does it burn.

Built to extremely fine tolerances, the fuel injectors and your pump rely on the diesel moving through them to keep their surfaces from wearing against one another.

The second task petrol doesn't do at all, and the first it does badly.

Being less viscous than diesel, petrol strips out the lubrication a fuel system needs, leaving a pump running on the mixture wearing itself. It is also made to resist igniting under compression — the opposite of what a diesel needs — which is why you hear the rattling.

Put those together and the shape of the trouble is clear.

Contact does not do the harm — movement does.

All a tank with petrol in it amounts to is a fuel fault.

A pump that has been running on that petrol is the start of a mechanical one, and whatever a worn pump sheds travels on with your fuel to your injectors further on.

## How serious is petrol in a diesel? Four scenarios our engineers see in Lindale

Fuelled up, not once started. The best case there can be.

Being on a forecourt is what makes this the case: elsewhere, your car has been driven there to begin with. With the petrol kept in your tank alone, it is emptied and rinsed on the spot, and nothing more is needed.

Started for a moment, or only the ignition on.

Once primed, your system has pulled petrol out of your tank up to the fuel filter and the lines.

Still normally easy: drain, flush, and the fuel filter seen to.

Driven a couple of miles. Now your pump has spent these miles labouring on thinned fuel.

The work is the tank, the fuel lines, your filter and clean fuel through the whole circuit, and how hard the car was driven matters as much as how far.

A school run to Lindale CofE Primary School is one matter.

Very different a second time: a trip to Lancaster, under 15 miles away, or any mileage on the M6, under 10 miles from Lindale, where the engine never stopped labouring hard.

Driven until it protested. Clattering, an uneven idle, smoke, a throttle that has gone soft.

What you are hearing is the engine signalling fuel that no longer runs like diesel.

Stop on the spot — on the verge on Smithy Hill, at the kerb, down a side road — and do not move it again.

A car pulled over soon very rarely has permanent damage, since the fuel drain and the flush, which still go first, take care of it.

## Myths Lindale people hear about petrol in a diesel

It will not be fine. The myth: "Fill it the rest of the way with diesel and it will be."

A fuller tank of the same mixture is all you get, because topping up removes nothing.

A diesel fuel system doesn't tolerate petrol by percentage in the way that advice supposes.

Myth: "A modern diesel can cope with a bit of petrol." If anything, the opposite.

At higher pressure, through finer components: that is how a newer diesel moves its fuel, and so the lubrication counts more, not less.

"It starts, it drives, and so no harm done" — the myth that catches most people than any other.

A petrol engine fed diesel normally will not run, and so the driver stops and the damage stops with them.

A diesel fed petrol generally starts, ticks over and drives away as though nothing has happened, whilst your pump grinds.

Fine and running are not the same thing.

"A drop of two-stroke oil and drive it home" — a myth, borrowed from a fix from years ago, for a distinct issue.

None of what petrol diluted is put back by it — and afterwards, that tank still contains the petrol.

If your engine has run, part of the petrol sits in your filter and the lines, not your tank — and the next start sends it straight back through your pump. So the myth "drain the tank yourself and you are sorted" does not stand up.

Also, a can of petrol drained at the roadside is genuinely dangerous.

## How it happens: petrol in a diesel

It is rarely carelessness, and no one does it on purpose.

The forecourt makes it simple: the petrol nozzle is the slimmer of the two, and it slips into a diesel filler with almost no resistance, while a diesel nozzle generally will not go into a petrol car at all. So the error runs one way.

It happens when routine and your car stop matching.

A new vehicle, a hire car or a courtesy car.

One petrol and one diesel on the driveway of the same household.

Your usual forecourt, its pumps now in a different order.

A train to catch, and a rushed fill on the way to Grange-Over-Sands.

The first fill-up in a diesel Volkswagen Tiguan after years of driving petrol is exactly the moment it happens.

With rain, a call arriving, or children to deal with, the hand simply does what it has always done.

## Next time you fill up around Lindale: avoiding petrol in a diesel

- Read the pump, not the colour. In the UK unleaded handles are usually green and diesel black, yet not on each forecourt. The label is what matters.

- The first fill in a new motor is the time to check your filler flap — on it, or on the cap, many motors state the fuel they take.

- A coloured fob or a sticker on the diesel's key does more than any amount of meaning to remember, for a house with one of each.

- Before the nozzle leaves the petrol pump the first time you fuel a hired or new vehicle, say "diesel" out loud. Silly, yes, yet it works.

- Thinking about something else is when this becomes an easy mistake to make, so tuck your phone away and keep your mind on the pump.

- Some diesels have a filler built to block a petrol nozzle, and devices you can add are available for motors without one. Such an inhibitor helps up to a point — as a safety net, not a reason to stop checking the pump.

- Spotting it halfway? Stop there and then. A weaker blend follows from less petrol inside the tank, yet your next stage remains the same: do not start it.

## Already put petrol in a diesel around Lindale?

The order of things is short, then.

Leave it unstarted, with your ignition switched off as well.

Ask the attendants to help you push it away from the petrol pump if you're still on the forecourt, whether that is BP or anywhere else.

Then call 0333 366 0103 and tell us what got in, roughly how much, and if it's run.

If it was AdBlue and not petrol, say so. That's a different issue — corrosion and deposits instead of lost protection — and it has its own page for Lindale.

## What makes one Lindale petrol in a diesel job cost more than the next

An honest single price doesn't exist here: four situations, four separate tasks.

What shifts the cost is mostly which of them you're in.

Two things come after that: the petrol that was put in as a proportion of what your tank holds, then the spot the car is in and whether a van can reach it safely.

What got in, how much, and whether it's run — three questions our engineers ask before pricing, not after, for precisely that reason.

With those replies, you get a straight figure rather than a range.

## About Lindale, briefly

Lindale is a small village in Cumbria, situated on the coastal plain near Morecambe Bay. Lindale has a population of around 547 people and is characterized by detached housing. Lindale sits at an elevation of 21 metres, close to nearby villages such as Hampsfield and Meathop. Lindale is located approximately 12 miles from Lancaster, a major city in the region.

## Across Cumbria and in Lindale: fuel drain cover

Hampsfield, Meathop and Eden Mount are among the spots around Lindale that the same vans work, answering petrol in diesel calls across Lindale's LA postcode area.

Our engineers drain wherever your vehicle is — your own driveway, a lay-by, a supermarket car park, a forecourt — so it does not have to come to us.

## In Lindale and still at the pump?

In that case, you could not be in a better position.

Keep it off. Call.
