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

Likely less than you are now — as long as nobody has started the car.

Until the ignition primes the pump, your starter turns, or the vehicle is driven, petrol in a diesel tank just rests there and does nothing. Which makes the honest reply to that first Kibworth Beauchamp query — "have I wrecked it?" — usually no.

Keep it like that: leave the motor off then phone Petrol in Diesel.

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

## Inside the motor: what petrol in a diesel really does

Diesel does two tasks on its way through an engine.

It protects to begin with, and only then does it burn.

Your high-pressure pump and your injectors are built to extremely fine tolerances, and the diesel passing through them is what keeps those surfaces from wearing down against each other.

The second job petrol does not do at all, and the first it does badly.

Being less viscous than diesel, petrol strips away the protection a fuel system needs, leaving a pump running on the blend wearing itself. It's also made to resist igniting under compression — the reverse of what a diesel needs — which is where you hear the rattling.

Together, those leave the shape of the issue clear.

It is circulation that causes the damage, not contact.

Any tank with petrol in it is a fuel issue.

Whatever a worn pump sheds goes on, borne by the fuel, into the injectors downstream, which is why a pump that has worked on the petrol is where a mechanical issue begins.

## Petrol in a diesel in Kibworth Beauchamp: how bad is it? Four cases

Filled up, never started. The best case there is.

Just the tank has petrol in it, so the job is clearing the tank and cleaning the fuel system where the vehicle stands. This situation can only really happen on a forecourt: anywhere else, the vehicle got there by being driven.

The ignition switched on, or a brief start.

Your system has been primed, so petrol has left the tank and got to your filter and your lines.

Still normally straightforward: drain, flush, and the filter dealt with.

Some miles driven, and your pump has spent every one of them working on diluted fuel.

Miles is only half of that; how hard it was driven matters just as much. Either way this work runs to the tank, the lines, your filter and clean fuel through the whole system.

Driving the children to Kibworth Church of England Primary School is one sort of trip.

Very different once more: a trip to Leicester, under 10 miles away, or some miles on the M1, under 10 miles from Kibworth Beauchamp, where your engine kept running hard.

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

What you are hearing is your engine reporting fuel that no longer acts like diesel.

Leave it wherever it has stopped: a lay-by, a quiet street, the verge on School Road.

A car pulled over soon very rarely has lasting damage, since the drain and the flush, which still come first, sort it out.

## Kibworth Beauchamp motorists and the petrol in a diesel stories they hear

Myth: topping up to full with diesel makes it fine. It does not.

Nothing comes out when you top up — the tank simply carries more of the same mixture.

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

"Modern diesels can handle a little petrol" — a myth, and nearer the opposite.

A current diesel sends its fuel through more precise components at higher pressure, which makes the lubrication count more, not less.

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

The driver of a petrol engine fed diesel usually stops, since it will not run, and the damage stops with them.

Feed petrol to a diesel and it generally starts, idles and drives away as if nothing has happened — all while its pump is wearing.

Running is not the same as fine.

An outdated fix for a different problem is behind this one. Myth: "Add some two-stroke oil and drive it home."

It doesn't put back what petrol has thinned, and that petrol is still inside your tank later.

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

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

## Why petrol in a diesel takes place so easily

A careless moment is seldom the cause, and nobody means to do it.

A diesel nozzle generally will not fit a petrol motor, yet the slimmer petrol nozzle goes into the filler of a diesel nearly without resistance — so forecourts make this one mistake easy, and only in one direction.

Habit and your car getting out of step is how it happens.

Courtesy car, hire car, or a motor that's brand new.

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

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

A rushed fill on the way to Market Harborough with a train to catch.

Years of petrol vehicles behind you, a diesel Volkswagen Golf in front of you at the forecourt for its first tank — that is when.

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 in Kibworth Beauchamp: preventing petrol in a diesel

- Not every forecourt in the UK follows green for unleaded and black for diesel, even if most usually do. Read the pump's label; the colour is just a hint.

- The first fill in an unfamiliar car is the time to check the filler flap — inside it, or on the cap, many vehicles state the fuel to use.

- Good intentions count for less than a sticker or a fob in a bright colour on the diesel's key if a house has one of each. So label it.

- It sounds daft and it works: on your first fill in a new or hired car, say "diesel" out loud before you take the nozzle off the petrol pump.

- Mistakes like this are simple to make whilst your mind is on something else, and so the phone goes away.

- A misfuel inhibitor helps, up to a point. Some diesels have a filler designed to block a petrol nozzle, and add-on devices exist for cars without one. They are a safety net, not a reason to stop reading the petrol pump.

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

## Already put petrol in a diesel around Kibworth Beauchamp?

Then the order of things is brief.

Do not switch your ignition on, and do not fire it up.

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

What was put in, roughly how much, and whether it's run: tell us those when you call 0333 366 0103.

If it was AdBlue instead of petrol, say so. That's a separate issue — corrosion and deposits rather than lost protection — and it has its own page for Kibworth Beauchamp.

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

There's no honest single quote for this, since the four scenarios above are four separate tasks.

Chiefly, the cost shifts with which situation you're in.

The ratio counts next, meaning how much of that tank is petrol, and then the position of the vehicle and whether getting to it is safe for our van.

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

Those answers are what change a range into one firm number.
