# Petrol in a Diesel Car in Little Braunston: What Happens Now

Not for a second, and not to move it: your motor stays off. Pause there.

Petrol in a diesel that hasn't been run is typically a drain plus a flush, done right where your car sits, and what you do in the next few minutes settles that far more than anything else.

From here on, in order, wherever you are in Little Braunston:

## Motor off: minute one with petrol in a diesel

First, these — in this order.

- The keys out of your ignition. Turning your ignition on can be all it takes to prime the fuel system, while priming draws petrol out of your tank toward the parts it damages. Leave the vehicle off completely.

- No diesel on top. More fuel in removes none of that petrol — it just leaves you with more of the same blend.

- Hazard lights on. If you're anywhere near moving traffic, make the vehicle easy to see before you do anything else.

- By hand, not under your engine: that is how it leaves the pump. Get the forecourt attendants to help you push, however short the miles.

- Which fuel, and about how much? Your receipt replies that, and that is where our questions start. Do not bin it.

Realised on the move? Get off at the next junction if you are on the M45, under 5 miles from Little Braunston, and pull over somewhere sensible — not at the services farther on. Step one comes after that.

## The fork in each Little Braunston fuel drain: has it run yet?

What comes after this turns on one answer, and only one.

Engine not run at all?

- Nowhere but that tank: that's where the petrol still is.

- Where your car stands is usually where this work is done: a drain, then a flush.

- This is the best spot to be in, and the reason step one counts.

If the engine has run, even for a moment:

- Your lines and your filter now hold petrol drawn from the tank.

- A bigger run takes it all the way to the high-pressure pump and the injectors.

- The farther it went, the larger the job — your lines, your filter, and now and then more besides.

Petrol doesn't lubricate. Diesel does, protecting the high-pressure pump and injectors as it passes through, which is why the line falls where it does.

A tank of petrol, left alone, hurts nothing.

Once it's pumped, petrol starts wearing whatever moves it.

## What to have ready when you call about petrol in a diesel from Little Braunston

Whether the van goes round or finds you depends on a little preparation.

- NN11 7 plus the remainder of the postcode makes the best way to start telling us where you are.

- The road or the car park. A road name helps — Maple Close, or wherever you have stopped.

- Or the landmark. A car park is quicker to find by what it serves, such as the one at Co-op Food.

- The make and model of the vehicle, and the fact it's a diesel.

- What was put in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Little Braunston, and so say which.

- About how much — in litres from your receipt, or by how long the nozzle stayed in.

- If it has run, how far plus how hard — and whether it's run at all.

- Whose vehicle it is. Some hire and company agreements want the owner to authorise the work, and that is easier settled before our engineers turn up than after.

Call 0333 366 0103 then. Writing to  is fine too if it can wait, with your car parked at home, going nowhere.

## Whilst you wait for a fuel drain around Little Braunston

Stick to these: well-meant help does the harm during the wait.

- Where the car has stopped decides where you wait. Somewhere exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety ahead of your car.

- Not to roll it a few yards, not to check it is all right, not as a passer-by's favour: nobody starts it.

- None of it gets that petrol back out — not two-stroke oil, not injector cleaner, not anything from your boot. So no additives.

- Siphoning petrol into a can at the roadside is risky — and it still leaves whatever fuel has already gone beyond that tank. Don't try a home-made drain.

- Even your radio or your windows aren't worth turning the ignition on for.

## Step by step: the fuel drain when our van gets there

- Three questions. What was put in, how much, and whether it has run. Those answers set this job, which is why the quote comes after them but not before.

- Next that tank is cleared, so the polluted fuel is taken out.

- The fuel lines are rinsed. If it ran, the petrol has moved beyond that tank, and the lines are carrying it.

- Your filter is sorted. Cleared, or replaced where the car has a workable one.

- Clean diesel goes in, and the system is primed.

- Starting the car. After your system is bled with fresh diesel, our engineers start it and make sure it runs smoothly.

Until it runs on clean diesel, our engineers stay with it.

It's very uncommon for a car caught soon to be left with permanent damage, and normal driving resumes straight away.

## After your fuel drain: back on the road around Little Braunston

- Drive normally. There is nothing special to do once it's been started on clean fuel.

- Watch the first miles. A warning light, smoke, a rough idle or a flat spot under your throttle tells you to pull over then call us back.

- Your paperwork answers the question a rental company, fleet manager or insurer may ask: what work was carried out. Keep it.

- The handle's colour isn't the thing to go by next time — the label on the petrol pump is.
