# The Next Steps, in Order: Petrol in a Diesel Car in Newtown

Stop. Motor off. Leave it like that — no second on, no moving it anywhere.

Emptied and purged, just where it sits: that's usually all an unrun diesel with petrol in it needs. Whether it remains that simple depends on the minutes to come far more than on everything else.

What follows is the order from here, wherever in Newtown you are.

## Petrol in a diesel, engine off — the first minute

Do these first, in this sequence.

- The ignition off, keys out. Turned on, your ignition can prime your system — and priming is what moves petrol out of the tank towards the components it harms.

- Don't top it up with diesel. Adding diesel removes nothing. You end up with a bigger tank of the same mixture.

- Make the vehicle easy to see first — hazards on — if there is moving traffic anywhere near you.

- The staff will usually help you roll it away from the petrol pump. Ask, then move it by hand — not on the motor, even for a couple of yards.

- Keep the receipt: the fuel and the rough amount are written on it, and they're what our technicians ask about first.

If you were still driving when you noticed, pull over somewhere sensible instead of pushing on for the services — on the M5, under 3 miles from Newtown, that means the next junction. Step one follows.

## Newtown fuel drain: has the motor run yet, or not?

From this stage on, everything hinges on a single answer.

If the motor has not run at all:

- Just your tank has petrol in it for now.

- Normally it is emptied and flushed right where the car stands.

- This is the best position to be in, and the whole reason step one matters.

If the motor has been run, even briefly:

- The fuel lines and the filter already carry petrol drawn out of the tank.

- A bigger run takes it right through to the high-pressure fuel pump and the injectors.

- Mileage is what turns it into a bigger job: flushed lines, a filter seen to, and at times more than that.

The line falls there since diesel lubricates your high-pressure pump and the injectors on its way through them — and petrol doesn't.

Petrol resting in a tank harms nothing.

Pump that petrol, though, and it grinds down the very parts doing the moving.

## Calling about petrol in a diesel from Newtown: what to have prepared

Whether the technician goes round or finds you comes down to a little preparation.

- TA6 3 plus the remainder of the postcode is the best way to begin telling us where you are.

- A road name is a help: Cavalier Close, say, or whatever street you have stopped in. A car park does the trick too.

- What a car park serves is the easiest way to find it, and so say the landmark — such as the one outside Aldi.

- That it is a diesel, along with the make and model of the car.

- What got in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Newtown, so tell us which.

- How much. Litres from the receipt, or how long the nozzle was in the filler.

- Has it run? If so, say how far it got, and the way it was driven.

- Hire or company car? Some contracts want the owner's go-ahead for the work, and sorting it before we arrive is quicker than after.

Call 0333 366 0103 once you have got that ready — or, if the car is at home, going nowhere, use .

## Waiting for a fuel drain around Newtown: what to do

The wait is where well-intended help does the harm. Stick to these.

- Safety before your car. If it has stopped somewhere unsafe, get yourself clear of the traffic and wait away from it. If it's safe where it stands, stay with it.

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

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

- No home-made draining. Siphoning petrol into a can by the roadside is risky, and it leaves your fuel that has already gone beyond your tank.

- Not for the radio, not for your windows: the ignition stays off.

## Van arrived? Your fuel drain, one stage at a time

- Three questions. What got in, how much, and whether it's run. Those answers shape this job, which is why our price comes after them but not before.

- Your tank is drained. The polluted mixture comes out of that tank.

- Petrol that has shifted beyond the tank travels in the fuel lines once it ran, and the lines are flushed to shift it.

- Cleared, or replaced if the vehicle has a serviceable one: the filter is sorted next.

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

- Our technicians fire it up only after new diesel has gone in and bled the system, then make sure that it's running properly.

Till it runs on new diesel, our technicians stay with it.

Lasting damage is very rare when it has been noticed early, so your car can go straight back to normal driving.

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

- After it's been started on fresh fuel, there's nothing special to do: drive normally.

- Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle tells you to pull over then ring us back.

- Hold on to your paperwork. A hire firm, a fleet manager or an insurer may ask what was done.

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