# How Worried Should You Be? Petrol in a Diesel Car in Lodge Park

Less than you likely are, if it has not been started.

"Have I ruined it?" is the first question everyone in Lodge Park asks, and the honest answer is normally no, since petrol left in a diesel tank harms nothing till it is drawn through the system — by ignition priming, by the starter, or by driving.

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

Read on for three things: the effect petrol has inside a diesel motor, the clues of how far it has spread, and the way to make sure you don't do it again.

## The engine and petrol in a diesel: what goes on

Diesel has two jobs on its way through a motor.

It lubricates first, and only then does it burn.

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

Of those two tasks, petrol handles the first badly and the second never.

It's runnier than diesel and takes away the lubrication the fuel system depends on, and so a pump running on a petrol mix is a pump wearing itself. And petrol is designed to resist igniting under compression, which is the reverse of what a diesel needs from its fuel. That's where the rattling comes from.

Seen together, they show the shape the problem has.

Not contact but movement is what causes the damage.

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

After your pump has been labouring on that petrol, a mechanical problem has begun: anything shed by a pump that's wearing down travels downstream to the injectors with the fuel.

## How bad is petrol in a diesel? Four scenarios our engineers see around Lodge Park

Filled up, never started. The best case there can be.

Being at a forecourt is what makes this the case: elsewhere, the vehicle has been driven there to begin with. With the petrol kept inside your tank alone, it's emptied and flushed right where it stands, and nothing more is needed.

Started for a moment, or just your ignition on.

Petrol has left that tank and got to the fuel filter and the lines, because the fuel system has been bled.

That is normally still a straightforward task — a drain, a flush, and the filter seen to.

Those few miles driven were your pump running on fuel weakened by petrol the whole way.

Tank, lines, filter, then clean fuel run through the whole system: that is this work, and the way the vehicle was driven counts as much as the distance.

Short trips, such as the school run to Oak Hill First School, are one thing.

Any distance on the M42, under 5 miles from Lodge Park, means your engine has worked hard throughout, and a run to Birmingham, under 15 miles away, makes a very different task too.

Knocking, a lumpy idle, smoke, a throttle gone soft: driven until it complained.

The fuel is not behaving like diesel any more, and your engine is telling you.

Stop where you are — on the verge on Holloway Drive, at the kerb, down a side road — and don't move it.

The drain and flush still go first, and they deal with it: if a vehicle is pulled over early, long-term damage is very uncommon.

## Petrol in a diesel myths Lodge Park drivers hear

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

Topping up removes nothing; it gives you a bigger tank of the same mixture.

The idea behind that advice — that diesel fuel systems accept petrol by percentage — is wrong.

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

At higher pressure, through more precise parts: that is how a modern diesel handles its fuel, and so the lubrication counts more, not less.

Myth: "If it starts and drives, there is no harm done." This is the one that fools motorists.

Any petrol engine fed diesel generally won't run, so the motorist stops and the harm stops with them.

Feed petrol to a diesel and it normally fires up, idles and pulls away like nothing has happened — all while its pump wears.

Running is not the same as fine.

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

What petrol has weakened remains diluted, and the petrol remains inside that tank regardless.

Myth: "Drain the tank yourself and you are sorted." After the motor has run, some of that petrol is no longer inside your tank: it is in the fuel filter and your lines, and it goes straight back through your pump on your next start.

On top of that, petrol cleared into a can by the road is truly dangerous.

## Petrol in a diesel: how does it happen?

It is seldom carelessness, and nobody does it on purpose.

A diesel nozzle mostly won't go into a petrol vehicle, yet the slimmer petrol nozzle goes into the filler of a diesel almost without resistance — so forecourts make this one error simple, and just in that direction.

It occurs when routine and the 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 ordinary forecourt, its pumps suddenly in a different order.

A hurried fill en route to Redditch with a train to catch.

The first fill-up in a diesel Renault Megane after years of driving petrol is precisely the moment it happens.

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

## Lodge Park motorists: how to prevent petrol in a diesel next time

- A green handle for unleaded and black for diesel is usual in the UK — but not on each forecourt. Go by the label on the petrol pump, not the colour.

- Many vehicles state the fuel type inside the filler flap or on the cap, so check there on your first fill in a car you don't know.

- Mark the key. In a home with one of each, a coloured fob or a sticker on your diesel's key does more than any amount of intending to remember.

- Say it before you lift it. On your first fill in a new or hired car, say "diesel" aloud before you lift the nozzle off the petrol pump. It seems silly and it does the trick.

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

- Up to a point, a misfuel inhibitor helps: some diesels have a filler built to refuse a petrol nozzle, and add-on devices are available for the remainder. Count it as a safety net, and keep checking the petrol pump.

- As soon as you notice, stop: less petrol inside that tank means a thinner mix. What to do next does not change, though — still do not fire it up.

## Lodge Park: already put petrol in a diesel?

The order of things is short, then.

Don't start the vehicle, and don't switch the ignition on.

Yet on the forecourt, at the nearest petrol station or anywhere else? Ask the staff to help you roll the vehicle clear of the pump.

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

Corrosion and deposits form the issue with AdBlue, whereas petrol means lost protection. So if it was AdBlue, say so — and see its own Lodge Park page.

## One petrol in a diesel task around Lodge Park costs more than another. Why?

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

The scenario itself does most of the work of moving the cost.

The proportion matters next, meaning how much of your tank is petrol, followed by the position of the car and whether getting to it is safe for our van.

Before any quote, not after, we ask three questions: the fuel that went in, its amount, and whether it has run. That is why.

Those replies are what turn a range into one firm number.
