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

Likely less than you already are — provided nobody has started the vehicle.

Everyone around Brandesburton starts with "have I wrecked it?", and the fair answer is normally no: petrol resting in that tank of a diesel remains harmless until priming, cranking or driving draws it into the fuel system.

Keep it that way: leave the motor off and ring Petrol in Diesel.

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

## What petrol in a diesel does to the motor

Passing through an engine, diesel does two jobs at the same time.

Before it combusts, it protects — then it ignites.

Built to very fine tolerances, the fuel injectors and your pump depend on your diesel moving through them to stop their surfaces wearing against one another.

Of these two tasks, petrol manages the first badly and the second not at all.

The clattering comes from petrol being made not to ignite when compressed, which is precisely the reverse of what a diesel needs. On top of that it is thinner than diesel, it strips away the protection the system depends on, and any pump running on such a mixture is wearing itself.

Combined, those leave the shape of the problem clear.

Contact doesn't do the damage — circulation does.

A tank with petrol in it is a fuel fault.

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

## Petrol in a diesel in Brandesburton: how serious is it? Four cases

Filled but not once started — the best it gets.

Being at a forecourt is what makes this possible: elsewhere, your car has been driven there to begin with. With that petrol kept in that tank alone, it is emptied and purged right where it stands, and nothing more is needed.

A moment's running, or merely the ignition on.

With the system primed, the fuel lines and filter already hold petrol that came from the tank.

Normally little more than clearing, purging and sorting your filter, and so still easy.

Your pump now worked a couple of miles on thinned fuel — that's what driving the vehicle meant.

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

Short trips, like the school run to Brandesburton Primary School, are one matter.

Driving as far as Kingston upon Hull, under 15 miles away, makes a very different job — as does any mileage on the M62, under 25 miles from Brandesburton, with the engine labouring hard the whole time.

Driven on until it complained — clattering, smoke, an uneven idle, a soft throttle.

The fuel isn't behaving like diesel any more, and the engine is telling you.

Whether it's the verge on Frodingham Road, a lay-by or a side street, stop where you are then leave it.

Lasting damage is very uncommon when a vehicle is stopped quickly, and the fuel drain and flush that still come first sort it out.

## Petrol in a diesel stories Brandesburton drivers hear

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

Topping up takes out nothing; it gives you a fuller tank of the same mixture.

The assumption behind the guidance — that diesel fuel systems accept petrol by percentage — is wrong.

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

At higher pressure, through finer components: that's how a newer diesel handles its fuel, and so the protection matters more, not less.

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

The motorist of a petrol motor fed diesel usually stops, since it will not run, and the harm stops there.

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

Fine and running are not the same thing.

Myth: "Add some two-stroke oil and drive the vehicle home." It is an outdated workaround for a distinct issue.

That petrol is still in that tank afterwards, and whatever it has thinned isn't put back.

If the engine has been run, part of the petrol is in the filter and the lines, not that tank — and your next start pulls it straight back through your pump. So the myth "drain that tank yourself and you're sorted" does not hold.

And, a can of petrol drained at the kerbside is truly dangerous.

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

On purpose? Never. Through carelessness? Seldom, if ever.

The petrol nozzle is the slimmer of the two and slips into a diesel filler with almost no resistance; a diesel nozzle mostly will not go into a petrol motor at all. The forecourt makes it easy, and the mistake runs one way.

The moment habit stops matching the vehicle is the moment it happens.

Hire cars, courtesy cars, and cars that are new to you.

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

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

Filling up in a rush on the way to Arram, with a train to catch.

Exactly the moment it takes place: after years of driving petrol, a driver fills a diesel Volkswagen Golf for the first time.

Throw in rain, a phone call or a back seat full of kids, and your hand does what it has always done.

## Next time you fill up around Brandesburton: preventing petrol in a diesel

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

- The first fill in a strange motor is the time to check the filler flap — on it, or on the cap, plenty of vehicles state which fuel to use.

- One of each in the household? Mark your key to the diesel — a coloured fob, a sticker — because intending to remember is not enough.

- "Diesel", aloud, before you lift the nozzle — every time a new or hired car gets its first tank. It seems daft. It works.

- Put your phone away. This is an easy mistake to make while you're thinking about something else.

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

- Noticing it mid-fill? Stop at once. A weaker blend follows from less petrol inside that tank, but your next stage remains the same: don't crank it.

## Put petrol in a diesel in Brandesburton already?

Short and simple, then, is the order of things.

Do not switch your ignition on, and do not start it.

The attendants on the forecourt — whether at Gulf itself or wherever you filled up — will normally help roll it away from the pump if you ask.

Ring 0333 366 0103 next, with three facts — the fuel, the approximate quantity, and if it's run.

Corrosion and deposits are the trouble with AdBlue, whereas petrol means lost protection. So if it was AdBlue, say so — and read its own Brandesburton page.

## Brandesburton petrol in a diesel tasks: why one costs more than another

An honest single price does not exist here: four scenarios, four separate jobs.

Mostly, the cost shifts with which one you're in.

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

That's why our engineers ask three questions before pricing instead of after: what was put in, how much, and if it has run.

Those replies turn a range into a straight figure.
