# Stanley: Petrol in a Diesel Car? Here Is What Happens

Stop. Engine off. Keep it like that — no moment on, no moving it anywhere.

Has not been run? Then petrol in a diesel tends to be a straightforward drain-and-flush job wherever your car has stopped — and nothing settles that as much as the next few minutes do.

What follows is the sequence from this point, wherever around Stanley you are.

## Minute one: petrol in a diesel, engine off

Go through the following in sequence, first.

- Bleeding the fuel system pulls petrol from your tank toward the parts it harms, and turning the ignition on can be enough to do that. So the keys get taken out, and your ignition remains off altogether.

- A fuller tank of the same mixture is all topping up gives you, since it removes nothing. So no more diesel.

- Near moving traffic? Then the hazards come on before everything else, so the vehicle is easy to spot.

- By hand, never under your engine: that is how it comes off the petrol pump. Get the forecourt attendants to help you roll, whatever the miles.

- Hold on to the till receipt. It says which fuel went in and about how much, which is the first thing we will ask.

If you were still driving when you noticed, pull over somewhere safe rather than pushing on for the services — on the A1(M), under 10 miles from Stanley, that means the next exit. Step one comes next.

## The fork in every Stanley fuel drain: has it run yet?

Everything after this point depends on one answer.

Not run, not even once:

- Just your tank has petrol in it for now.

- The job is a simple drain and a flush, usually done where your car is.

- This is as good as it gets — which is the whole point of step one.

Run at all, even for a second:

- Out of that tank, past the filter, into the fuel lines: that's how far that petrol has got.

- On a bigger run it has got to your high-pressure pump and the injectors.

- Flushing the lines, the fuel filter sorted, occasionally more: the job grows as the mileage does.

Petrol doesn't lubricate. Diesel does, protecting the pump and injectors as it flows through, which is why the line sits where it does.

A tank of petrol, left alone, hurts nothing.

Petrol being pumped is grinding down the components that move the vehicle.

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

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

- Where you are. A postcode beginning DH9 0 is the best place to start.

- Name the road — A693 or wherever you have pulled up — or the car park.

- Describe a car park by what it serves — the one at Heron Foods, for instance — and it's far quicker to find.

- That it is a diesel, plus the make and model of your car.

- Tell us which was put in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Stanley.

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

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

- Settle who owns your car before we turn up: some hire or company agreements want the owner to approve the work, and that is faster beforehand.

Call 0333 366 0103 next. Writing to  works too if it can wait, with the car left at home, going nowhere.

## The wait for a Stanley fuel drain, and what to do in it

The wait is where well-meant help does the damage. Stick to these.

- Wait with the car if it's safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it.

- A helpful passer-by does not start it. Nor does anybody wanting to check it still works, or rolling it a few yards.

- No additives. Two-stroke oil, injector cleaner, anything from your boot — none of it takes that petrol back out.

- A home-made drain leaves the fuel that has already gone beyond the tank, and siphoning petrol by the road is dangerous too.

- Leave the ignition off — your windows and your radio included.

## When the van arrives: your fuel drain, step by step

- The price comes after three questions, not before them — what got in, how much, and if it has run — since the answers shape this job.

- Emptying it's how the mixture gets taken out of the tank.

- If it ran, the fuel lines are carrying petrol that has shifted beyond that tank — so they are rinsed.

- Cleaned, or replaced if the vehicle has a serviceable one: the fuel filter is dealt with next.

- Clean diesel goes in, then your system is primed.

- The start-up. With new diesel in and your system primed, it's started and checked to make sure it runs smoothly.

Till it runs on clean diesel, we remain with it.

It is very uncommon for a vehicle caught soon to be left with lasting damage, and normal driving resumes straight away.

## Back on the road around Stanley after your fuel drain

- Drive normally. There is nothing unusual to do after it has been started on clean fuel.

- Keep an eye on the first miles. A warning light, smoke, a rough idle or a flat spot under the throttle means pull over then ring us back.

- The work may matter later with a hire company, an insurer or a fleet manager. Keep the documents.

- Read the label on the petrol pump next time, not the colour of its handle.
