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

Not for a second, and not to move it: the motor stays off. Pause there.

Petrol in a diesel that has not been run is usually a simple drain and a flush, done right where your vehicle sits, and what happens in the next few minutes determines that far more than anything else.

Below is the sequence from this point, anywhere in Aldham you happen to be.

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

In this sequence, and before everything else:

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

- Do not top it up with diesel. Adding diesel removes nothing. You end up with a fuller tank of the same mix.

- Being seen comes before the rest beside moving traffic: switch your hazards on, and only then think about anything else.

- However short the distance, starting it to shift it is the thing to avoid. On a forecourt, push it clear of the petrol pump by hand instead, then ask the attendants to help.

- Hold on to your receipt: the fuel and the rough amount are written on it, and they are what our engineers ask about first.

On the M11, under 25 miles from Aldham, the next junction is the spot to leave it; elsewhere, the first safe location to stop. Do not push on to the services. Then go back to stage one.

## The fork in each Aldham fuel drain: has it run yet?

Everything after this point depends on one answer.

Motor not run at all?

- All the petrol remains inside your tank, and only there.

- Where the vehicle stands is normally where this work is done: a drain, then a flush.

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

If it's been started, even for a moment:

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

- A bigger run carries it right through to your high-pressure pump and your injectors.

- The job expands with the distance — lines rinsed, filter seen to, occasionally more.

Petrol does not lubricate. Diesel does, protecting your high-pressure pump and injectors as it passes through, which is why the line sits where it does.

Nothing is harmed by petrol that is just sitting in a tank.

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

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

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

- CO6 3 and the rest of the postcode makes the best way to begin telling us where you are.

- Name the road — The Chase or wherever you have stopped — or the car park.

- Car parks are found more easily by what they serve: say the one at Aldi, and it's easy.

- The make and model of the car, and the fact it is a diesel.

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

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

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

- Whose motor it is. Some hire and company agreements want the owner to authorise the work, and that is easier settled before we get there than after.

Next, 0333 366 0103. Not time-critical, the car left at home with nowhere to be? Then  will do as well.

## While you wait for a fuel drain around Aldham

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

- Where the car has stopped decides where you wait. Exposed: away from it, clear of the traffic. Safe: with it. Either way, safety ahead of the vehicle.

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

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

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

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

## The fuel drain, step by step, after our van arrives

- Fuel, quantity, whether it's run: the answers set this job, and that is why you get a price after them instead of before.

- Out of your tank comes the tainted blend: the tank is emptied.

- Purging your lines comes next, because a vehicle that ran has petrol past your tank, inside your lines themselves.

- Where the car has a serviceable filter, it is replaced; if not, cleared.

- Your system is primed on fresh diesel.

- Our technicians fire it up only after new diesel has gone in and primed your system, then check that it is running correctly.

Our technicians remain until it's running on new diesel.

If it has been caught quickly, permanent damage is very rare, and the car goes back to normal driving right away.

## Aldham, after the fuel drain: back on the road

- Started on clean diesel, it asks nothing unusual of you. Simply drive normally.

- The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your cue to stop and call us again.

- The documents answers the query a rental company, fleet manager or insurer may ask: what work was carried out. Keep it.

- Next time, go by the petrol pump's label rather than the colour of its handle.
