# What Happens Now: Petrol in a Diesel Car in Castle Hill

Whatever you do, never switch the motor on, even for a moment, to move the vehicle. Stop; leave the vehicle off.

The next few minutes settle it far more than anything else: petrol in a diesel still unrun usually amounts to emptying then flushing, on the spot.

Here's the sequence of things from now, anywhere you're in Castle Hill.

## Petrol in a diesel? What to do in minute one

Work through the following in sequence, first.

- Priming the system draws petrol from your tank toward the components it damages, and switching the ignition on can be enough to do that. So your keys come out, and your ignition stays off altogether.

- A bigger tank of the same mix is all adding diesel leaves you, since it takes out nothing. So no extra diesel.

- Make the car simple to see before anything else — hazards on — if there is traffic going past anywhere close to you.

- The staff will normally help you push it clear of the pump. Ask, and move it by hand — never under your engine, even for a few yards.

- The first thing you will be asked is which fuel you put in and about how much — and the till receipt says both. Keep it.

Realised on the move? Get off at the next exit if you are on the M54, under 10 miles from Castle Hill, and stop somewhere sensible — not at the services further on. Step one comes after that.

## Has it run yet? The fork in each Castle Hill fuel drain

What happens next rests on one answer, and only one.

If it has not once been started:

- Only your tank has petrol in it so far.

- Draining and flushing, on the spot, is usually all of it.

- Step one matters for exactly this reason: it is the best spot to be in.

If it has been started, even for a second:

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

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

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

The reason the line falls there: diesel protects the high-pressure fuel pump and the fuel injectors as it passes through them, and petrol does not.

A tank of petrol, left still, damages nothing.

The parts that shift it are grinding the moment petrol is being pumped.

## Castle Hill, petrol in a diesel: have these ready before you call

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

- Your whereabouts: a postcode beginning WV16 4 works best.

- Wherever you have parked, the road's name is useful — whether that's New Road or somewhere else — and so does the name of a car park.

- Or the landmark. A car park is easier to find by what it serves, like the one outside M&S Simply Food.

- Make and model of your car, and the fact it's a diesel.

- Which went in matters: AdBlue is a separate job from petrol, and Castle Hill has a page for it. So say.

- How long the nozzle was in, or the litres from your receipt — whichever tells us how much.

- Whether it's run. Then if it has, how far plus how heavily.

- Whose car it is. Some hire and company contracts want the owner to authorise this work, and that's quicker settled before we arrive than after.

Then phone 0333 366 0103. If it can wait — the vehicle is at home with going nowhere —  works too.

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

Hold to these: well-intended help causes the damage during the wait.

- Your safety comes before the car. Somewhere dangerous? Get clear of the traffic and wait away from it. Safe where it sits? Stay with it.

- A kind passer-by does not start it. Nor does anyone wanting to check it still works, or moving it a couple of yards.

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

- Emptying it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and your fuel beyond the tank stays where it is regardless.

- The ignition stays off. Even for the radio or the windows.

## Step by step: the fuel drain when the van arrives

- Three queries. What got in, how much, and if it's run. The replies decide this job, which is why the quote comes after them but not before.

- The tank is drained. The polluted mixture comes out of the tank.

- Cleaning the fuel lines follows, since a car that ran has petrol past your tank, inside your lines themselves.

- Your filter is dealt with. Cleared, or replaced where your car has a serviceable one.

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

- Our technicians fire it up only after fresh diesel has gone in and bled the fuel system, then make sure that it is running smoothly.

Our engineers remain until it is running on new diesel.

It is very unusual for a car caught early to be left with permanent damage, and normal use starts again at once.

## Castle Hill, after the fuel drain: back on the road

- Nothing special is needed after a start with clean diesel — ordinary driving will do.

- Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or the throttle hesitating: pull over and ring us back.

- An insurer, a fleet manager or a hire company may ask what was carried out, and so keep the paperwork.

- Next time, trust the petrol pump's label instead of the colour of its handle.

## Leave it off and ring: petrol in a diesel in Shropshire

Keys out, engine off, the receipt in your pocket: that's step one done. The remainder is for Petrol in Diesel, wherever the car is — forecourt, roadside or driveway.
