# Wicken Green Village: Petrol in a Diesel Car? How Worried to Be

Far less than you probably are, provided it has not been started.

Till your ignition primes the pump, your starter turns, or your car is driven, petrol in a diesel tank just waits there and does nothing. Which makes the honest reply to the first Wicken Green Village question — "have I ruined it?" — normally no.

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

What petrol actually does to a diesel, how to judge how far it's gone, and how to keep it from happening a second time: that's the rest of this page.

## What petrol in a diesel does to your engine

Two jobs fall to diesel on its journey round a motor.

Before it burns, it lubricates — then it ignites.

Built to extremely fine clearances, the injectors and the pump depend on the diesel flowing 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.

It is thinner than diesel and strips away the lubrication the fuel system rests on, so a pump running on a petrol blend is a pump wearing itself. And petrol is designed to resist igniting under compression, which is the opposite of what a diesel needs from its fuel. That's where the clattering comes from.

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

The harm is done by movement, not by contact.

Where that petrol is only inside your tank, it's an issue of fuel, nothing more.

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

## Four situations our engineers see around Wicken Green Village: how serious is petrol in a diesel?

Filled up, and not started: no case is better.

Only your tank has petrol in it, and so the task is emptying that tank and purging your system where your car stands. This situation can only truly happen at a forecourt: anywhere else, the car got there by being driven.

Ignition on, or started for a moment.

Petrol has come out of that tank and reached the fuel filter and the fuel lines, since the system has been bled.

Usually little more than emptying, cleaning and sorting the fuel filter, and so still simple.

Those few miles driven meant the pump running on fuel thinned by petrol throughout.

How hard your car was driven matters as much as how far, and the work covers your tank, the fuel lines, the filter and fresh fuel through the whole system.

On the school run to Blenheim Park Academy, the miles is small.

Getting as far as Norwich, under 50 miles away, makes a very different job — as does any mileage on the A1(M), under 50 miles from Wicken Green Village, with the engine running hard the whole time.

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

That's your motor telling you its fuel has stopped behaving like diesel.

Leave it wherever it has stopped: a lay-by, a side street, the verge on Bramble Close.

What goes first is still the fuel drain and flush-through, and that takes care of it, with permanent damage very unusual if a vehicle is pulled over soon.

## Stories Wicken Green Village people hear about petrol in a diesel

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

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

That guidance presumes a diesel fuel system handles petrol by percentage. It doesn't.

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

Smaller components and higher pressure are how a current diesel runs its fuel, and that makes the protection 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 engine and it usually won't run, so the motorist stops — and the damage stops with them.

Feed petrol to a diesel and it usually starts, ticks over and pulls away as if nothing has happened — all the while its pump is wearing.

Running is not the same as fine.

Myth: "Add some two-stroke oil and drive the vehicle home." It's an old fix for a different problem.

That petrol is still inside the tank after that, and what it has thinned isn't put back.

Once your engine has been run, part of that petrol sits in your filter and the lines, not that tank — and the next start sends it right back through the pump. So the myth "drain your tank yourself and you are sorted" doesn't hold.

Also, a can of petrol drained by the roadside is genuinely risky.

## Why petrol in a diesel occurs at all

A careless moment is seldom the cause, and no one means to do it.

A diesel nozzle generally will not fit a petrol vehicle, but the smaller petrol nozzle goes into the filler of a diesel almost without resistance — so forecourts make this one mistake straightforward, and only in one direction.

It occurs when routine and the car stop matching.

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

Households running one of each, petrol and diesel.

A familiar forecourt with the pumps in a different order.

Fuelling up in a hurry en route to the nearest station, with a train to catch.

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

Throw in a back seat full of kids, a phone call or rain, and habit takes over.

## Preventing petrol in a diesel next time you fill up in Wicken Green Village

- Check the petrol pump, not the colour. In the UK unleaded handles are normally green and diesel black, yet not on each forecourt. The label is what counts.

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

- One of each in the household? Label the key to your diesel — a bright fob, a sticker — because meaning to remember is not enough.

- Before the nozzle comes off the pump the first time you fuel a hired or new car, say "diesel" aloud. Daft, yes, yet it does the trick.

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

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

- Less petrol makes a thinner mixture, and so stop as soon as you realise — while remembering that your next step is unchanged. It is still not to start it.

## Already put petrol in a diesel around Wicken Green Village?

Then the order of things is brief.

Don't turn your ignition on, and don't start it.

If you are still at the forecourt — Shell or anywhere else — ask the attendants to help you roll the car clear of the pump.

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

Say so if it was AdBlue instead of petrol: it is a different problem, with its own page for Wicken Green Village, since AdBlue brings corrosion and deposits rather than lost lubrication.

## What makes one Wicken Green Village petrol in a diesel task cost more than the next

A fair single quote does not exist here: four situations, four separate tasks.

Mostly, your cost shifts with which one you are in.

Two things come after that: the petrol that got in as a share of what your tank holds, then the spot your car is in and whether a van can get to it safely.

Three questions come first, before any quote, rather than after — what went in, how much, has it run — and this is the reason.

Those answers turn a range into a straight figure.
