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

Unstarted? Then less anxious than you probably are.

"Have I wrecked it?" is the first question anyone around Bradwell asks, and the honest answer is generally no, since petrol resting in a diesel tank hurts nothing till it's dragged through the system — by ignition priming, by your starter, or by driving.

Petrol in Diesel is who to call, with the motor left off, so it stays that way.

Keep reading for three things: the effect petrol has inside a diesel engine, the clues of how far it has got, and ways to make sure you never repeat it.

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

Passing through a motor, diesel does two things at once.

It burns, and before it combusts it protects.

Designed to very fine tolerances, your injectors and your pump rely on the diesel moving through them to keep their surfaces from wearing against one another.

Petrol handles the first job poorly and the second not at all.

It is runnier than diesel and takes away the protection the 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.

Together, those make the shape of the problem clear.

Contact doesn't do the damage — movement does.

Any tank with petrol in it is a fuel problem.

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

## How serious is petrol in a diesel? Four situations we see in Bradwell

Fuelled but not once started — as good as it gets.

That petrol is in the tank and only that tank, and the job is a drain and a flush where the car stands. This is the one scenario that can only really occur at a forecourt, as anywhere else your car has been driven to get there.

Ignition on, or started for a second.

Petrol has left your tank and reached the filter and the fuel lines, because the fuel system has been bled.

Still normally easy: drain, flush, and the filter sorted.

Your pump has worked a couple of miles on diluted fuel — that is what driving the car meant.

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

The school run to Sun Academy Bradwell is one matter.

Very different again: a trip to Stoke-on-Trent, under 3 miles away, or some miles on the M6, under 5 miles from Bradwell, where the engine kept working hard.

Driven on till it complained — rattling, smoke, a ragged idle, a dead throttle.

The engine is telling you your fuel is no longer acting like diesel.

Pull up where you are — on the verge on Bradwell Lane, at the kerb, down a side road — and don't move it.

Long-term damage is very rare when a car is stopped quickly, and the drain and flush-through that still come first sort it out.

## What Bradwell people get told about petrol in a diesel — and the stories in it

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

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

Percentage isn't how a diesel fuel system tolerates petrol, however much that advice supposes.

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

A newer diesel sends its fuel through smaller components at higher pressure, which makes the protection count more, not less.

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

Diesel in a petrol motor normally means a motor that will not run: the driver stops, and so does the harm.

A diesel fed petrol normally starts, ticks over and drives away as though nothing has happened, whilst your pump grinds.

Fine and running are not the same at all.

Myth: "Add some two-stroke oil and drive it home." It is an outdated workaround for a different problem.

It does not put back what petrol has weakened, and that petrol is still inside the tank later on.

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

It's also really hazardous to drain petrol into a can at the kerbside.

## Petrol in a diesel: how does it take place?

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

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

Routine and your car getting out of step is when it takes place.

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

Two vehicles on one driveway, one petrol, one diesel.

The pumps in a different order on a familiar forecourt.

Filling up in a rush on the way to Longport, 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.

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

## How to prevent petrol in a diesel on your next fill-up around Bradwell

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

- Check your filler flap. Many cars state the fuel inside the flap or on the cap. Look at it on your first fill in any motor you do not know.

- Good intentions count for less than a sticker or a fob in a vivid colour on the 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" out loud before you lift the nozzle off the petrol pump. It seems silly and it works.

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

- Some diesels come with 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 safety net, not a reason to stop reading the pump.

- Stop as soon as you realise. Less petrol inside your tank makes a thinner mix. It doesn't change what to do next, which is still not to start the car.

## Bradwell: already put petrol in a diesel?

The order of things is brief, then.

Leave it unstarted, with the ignition switched off too.

Ask the attendants to help you push it clear of the petrol pump if you are still at the forecourt, whether that's Esso or anywhere else.

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

Corrosion and deposits are the issue with AdBlue, whereas petrol brings lost protection. So if it was AdBlue, say so — and see its own Bradwell page.

## One petrol in a diesel task in Bradwell costs more than another. Why?

A fair single quote doesn't exist here: four scenarios, four separate tasks.

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

Where your car is matters too, and whether a technician can safely reach it, after the share of petrol to what that tank takes.

What went in, how much, and if it's run — three questions our engineers ask before quoting, not after, for exactly that reason.

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