# What Happens Now: Petrol in a Diesel Car in Newtown

Not for a moment, and not for moving it: the motor stays off. Pause there.

Emptied then flushed, just where it is: that's generally all an unrun diesel with petrol in it takes. Whether it stays that simple depends on the minutes ahead more than on anything else.

Here's the order of things from here, wherever you're around Newtown.

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

Go through the following in sequence, before you do anything else.

- Keys out of the ignition. Turning your ignition on can be enough to prime the system, while priming pulls petrol out of your tank toward the parts it harms. Keep the vehicle off altogether.

- Topping up with diesel seems like it thins the issue. It doesn't: nothing comes out, and the tank simply holds more of the same.

- Hazards on. If you are at all near moving traffic, make the vehicle easy to see before you do anything else.

- However short the distance, starting it to move it is the thing to avoid. At a forecourt, push it clear of the pump by hand instead, and ask the attendants to help.

- Keep the receipt. It says which fuel was put in plus about how much, which is the first thing we will ask.

Realised on the move? Get off at the next exit if you are on the M54, under 15 miles from Newtown, and stop somewhere sensible — not at the services further on. Step one starts after that.

## Every Newtown fuel drain starts here: has your motor run?

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

Engine never run at all?

- All the petrol remains inside that tank, and just there.

- A drain and flush, on the spot, is normally the whole job.

- Stage one matters for exactly this reason: it's the best place to be in.

If it has been started, even for a moment:

- Your lines and the filter now hold petrol drawn out of that tank.

- On a bigger run it has got to the high-pressure pump as well as the fuel injectors.

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

The reason the line falls there: diesel protects the high-pressure pump and the fuel injectors as it flows through them, and petrol doesn't.

Nothing is harmed by petrol that is only resting in a tank.

The components that move it are wearing the moment petrol is being pumped.

## Before you call about petrol in a diesel around Newtown: what we need

A little preparation is the difference between a technician that finds you and a van that goes round.

- Your location: a postcode beginning SY4 2 works best.

- A road name helps: Holberton Way, say, or whichever street you've stopped in. A car park does the trick too.

- Describe a car park by what it serves — the one outside Co-op, for example — and it's much easier to find.

- The vehicle. Make, model, plus that it is a diesel.

- Tell us which went in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Newtown.

- The amount: your receipt's litres, or otherwise how long you held the nozzle in.

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

- Hire or company car? Some agreements want the owner's authorisation for the work, and sorting it before our technicians turn up is faster than afterwards.

Call 0333 366 0103 then. Writing to  works as well if it can wait, with the car parked at home, going nowhere.

## Whilst you wait for a fuel drain around Newtown

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

- Safety before the vehicle. If it has stopped somewhere unsafe, get yourself away from the traffic then wait away from it. If it is safe where it is, wait with it.

- No one — however helpful — starts it, whether to see if it runs or to shift the vehicle a short way.

- Additives stay in the boot. Injector cleaner and two-stroke oil take none of the petrol out a second time.

- No DIY draining. Siphoning petrol into a can at the roadside is hazardous, and it leaves the fuel that has already gone beyond that tank.

- Even your radio or the windows are not worth switching the ignition on for.

## The fuel drain, step by step, after the van gets there

- Our price comes after three questions, not before them — what got in, how much, and whether it has run — since the answers decide the job.

- That tank is emptied. The contaminated mix comes out of that tank.

- If it ran, your lines are holding petrol that has shifted beyond your tank — so they're flushed.

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

- Fresh diesel in, and your system primed.

- The first start on new diesel. When priming is finished, the motor is started and our technicians make sure that it runs correctly.

Only once it is running on clean diesel do our engineers go.

It is very unusual for a vehicle caught early to be left with lasting damage, and normal use starts again right away.

## Newtown, after your fuel drain: back on the road

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

- The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a hesitant throttle is your signal to stop then call us a second time.

- Keep your documents. A hire firm, a fleet manager or an insurer may ask what was carried out.

- Next time, read the petrol pump. The label, not the colour of its handle.
