# Petrol in a Diesel Car in Acklam: How Worried Should You Be?

Not started? Then less anxious than you likely are.

Everyone in Acklam begins with "have I wrecked it?", and the honest answer is normally no: petrol resting in your tank of a diesel stays harmless till priming, cranking or driving pulls it into the system.

Keep it that way: leave your engine off then phone Petrol in Diesel.

What petrol actually does to a diesel, how to judge how far it has travelled, and how to stop it from happening a second time: that is the remainder of this page.

## Petrol in a diesel: what does it do to the engine?

Passing through a motor, diesel is doing two jobs at once.

Before it burns, it lubricates — and then it ignites.

What stops the surfaces inside your high-pressure pump and your injectors from wearing against one another is the diesel flowing through them — they are made to very fine gaps.

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

The rattling comes from petrol being designed not to ignite when compressed, which is precisely the reverse of what a diesel needs. On top of that it is runnier than diesel, it strips out the lubrication your system depends on, and any pump working on such a mix is wearing itself.

The shape of the problem is plain when you put those together.

Not contact but circulation is what causes the harm.

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

After the pump has been labouring on that petrol, a mechanical issue has begun: whatever is shed by a pump that is grinding travels onward to your injectors with your fuel.

## Acklam, petrol in a diesel: four cases, from mild to serious

Fuelled but never started — the best it gets.

On a forecourt, and truly only there, that petrol is still confined to your tank — because anywhere else the vehicle was driven to get to it. The task is emptying and flushing on the spot.

The ignition turned on, or a short start.

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

Drain, flush, deal with the fuel filter: still usually simple.

Those few miles driven were the pump working on fuel thinned by petrol throughout.

How hard the vehicle was driven matters as much as how far, and this work covers that tank, the lines, your filter and clean fuel through the entire system.

The school run to Kader Academy is one thing.

A run as far as Durham, under 25 miles away, is a very different task. So is any miles on the A1(M), under 15 miles from Acklam, where your engine has been labouring hard the whole time.

It protested, and only then stopped: smoke, rattling, a throttle gone soft, an idle gone ragged.

The fuel isn't behaving like diesel any more, and your motor is saying so.

Leave it where it stops: a lay-by, a quiet street, the verge on Bewley Grove.

The drain and flush-through still go first, and they deal with it: if a vehicle is stopped soon, lasting damage is very rare.

## Petrol in a diesel stories Acklam motorists hear

"Top it up the rest of the way with diesel and it will be fine" — a myth. It won't.

Topping up removes nothing; it gives you a fuller tank of the same mix.

That advice assumes a diesel fuel system tolerates petrol by percentage. It doesn't.

If anything, the reverse holds. Myth: "A newer diesel can cope with a bit of petrol."

A modern diesel sends its fuel through finer components at higher pressure, which makes the lubrication matter more, not less.

The myth that catches motorists off guard: if it starts and drives, it must be unharmed.

Feed diesel to a petrol motor and it generally won't run, and so the motorist stops — and the harm stops with them.

Nothing looks to have happened when a diesel fed petrol fires up, ticks over and drives away, which it usually will; meanwhile your pump wears.

Running is not the same as fine.

Myth: "Add some two-stroke oil and drive the car home." It is an old fix for a separate issue.

What petrol has thinned remains weakened, and that petrol remains in the tank anyway.

The next start sends petrol back round your pump out of your lines and your filter, where some of that ends up after the motor has been run. That's why draining your tank yourself does not leave you sorted — a myth.

Besides, petrol cleared into a can by the road is genuinely hazardous.

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

It's seldom carelessness, and nobody does it on purpose.

The petrol nozzle is the narrower of the two and slides into a diesel filler with almost no resistance; a diesel nozzle generally will not go into a petrol motor at all. The forecourt makes it simple, and the slip runs one way.

It takes place when routine and your car stop matching.

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

A household with one petrol and one diesel on the driveway.

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

A train to catch, and a rushed fill on the way to James Cook University Hospital.

Years of petrol cars behind you, a diesel Renault Megane in front of you on the forecourt for its first tank — that's when.

With rain, a call arriving, or a car full of children to deal with, the hand just does what it always has.

## Avoiding petrol in a diesel next time you fill up around Acklam

- The label is what counts, so read the pump rather than the colour: in the UK unleaded handles are normally green and diesel black, but not on each forecourt.

- In a car you do not know, look inside the flap over the filler or at the cap before the first fill: plenty of cars state the fuel there.

- Good intentions do less than a sticker or a fob in a bright colour on your diesel's key when a house has one of each. So label it.

- Say it before you lift it. On the first fill in a new or hired car, say "diesel" aloud before you take the nozzle off the pump. It seems daft and it works.

- Put the phone away. This is an easy mistake to make whilst you are thinking about something else.

- Add-on devices exist for motors without one, and some diesels come with a filler that won't accept a petrol nozzle. Useful — but a backstop only, never a reason to stop checking the label.

- Stop as soon as you notice. Less petrol in that tank means a thinner mixture. It does not change what to do next, which is still not to crank it.

## Put petrol in a diesel around Acklam already?

The order of things is short, then.

Leave it unstarted, with your ignition off too.

The attendants on the forecourt — whether at Esso itself or wherever you filled up — will usually help push it away from the pump if you ask.

Next, 0333 366 0103. We will ask what went in, about how much, and if it has been run.

AdBlue, not petrol? Then tell us. Corrosion and deposits, not lost protection, make it a different issue — Acklam has a page all for it.

## What makes one Acklam petrol in a diesel task cost more than the next

There is no fair single price for this, since the four scenarios above are four different tasks.

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

Next it's the share — how much petrol got in against how much that tank holds — and after that where your car is and whether a van can reach it safely.

Before any quote, not after, come three questions: your fuel that got in, its quantity, and if it has run. That is why.

A range becomes a straight figure once the answers are in.
