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

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

Has not been run? Then petrol in a diesel will usually be a simple drain-and-flush job wherever the vehicle has stopped — and no other factor settles that more than the next few minutes do.

Anywhere you happen to be around Castleblair Park, here is how things run from now.

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

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

- Take your keys out. Even the ignition by itself can prime the fuel system, pulling petrol out of your tank to precisely the components it harms, so keep the car alone entirely.

- No diesel on top. More fuel in takes away none of the petrol — it only makes you with extra of the same mixture.

- Make the car easy to see first — hazard lights on — if there is traffic going past anywhere near you.

- Off the petrol pump by hand. At a forecourt, ask the staff to help you push it clear of the petrol pump. Do not crank it to move it, however short the distance.

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

Noticed on the move? Get off at the next junction if you're on the A823(M), under 3 miles from Castleblair Park, and pull over somewhere sensible — not at the services further on. Stage one starts after that.

## Castleblair Park fuel drain: has your engine run yet, or not?

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

If your motor hasn't run at all:

- No place but that tank: that's where the petrol still is.

- A drain and flush, on the spot, is usually all of it.

- No spot is better, and it's why the first stage counts so much.

If it has been started, even for a second:

- The fuel lines and the fuel filter already hold petrol pulled out of the tank.

- Run it farther and that petrol reaches the injectors, having gone through your fuel pump first.

- Lines flushed, the fuel filter dealt with, and sometimes more: the job grows as the distance does.

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

A tank of petrol, left alone, hurts nothing.

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

## Castleblair Park, petrol in a diesel: have these prepared before you call

Get ready a little, and the van finds you instead of circling.

- Where you are. A postcode starting KY12 9 is the best start.

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

- Car parks are located more easily by what they serve: say the one outside Tesco, and it is simple.

- The car. Make, model, and that it is a diesel.

- Which went in counts: AdBlue is a separate job from petrol, plus Castleblair Park has a page for it. So tell us.

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

- Has it run? If so, tell us how far it went, and the way it was driven.

- Sort who has the car before our technicians get there: some hire or company contracts want the owner to approve the work, and that is faster first.

Then ring 0333 366 0103. If it can wait — the car is at home and going nowhere —  does the trick too.

## Castleblair Park fuel drain on its way? Whilst you wait

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

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

- A kind passer-by does not start it. Nor does anyone checking it still works, or rolling it a few yards.

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

- No DIY emptying. Siphoning petrol into a can at the kerbside is dangerous, and it leaves your fuel that has already gone beyond that tank.

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

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

- Fuel, volume, whether it has run: those replies decide the job, and that is why you get a quote after them instead of before.

- The tank is cleared. The polluted mixture comes from that tank.

- If it ran, the lines are carrying petrol that has moved beyond your tank — so they are flushed.

- Then your filter: swapped where there is a usable one, cleared where there's not.

- Fresh diesel in, and the system primed.

- First start on new diesel. When bleeding is done, the motor is fired up and our engineers confirm that it runs correctly.

Only once it is running on clean diesel do we leave.

Long-term damage is very unusual if it has been spotted quickly, so the car can go right back to normal driving.

## Back on the road around Castleblair Park after the fuel drain

- Started on new diesel, it needs nothing unusual of you. Just drive normally.

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

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

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