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

Not for a second, and not for moving it: your motor remains off. Pause there.

Drained and purged, just where it sits: that is usually all an unrun diesel with petrol in it takes. Whether it remains that straightforward depends on the minutes to come more than on anything else.

Below is the order from here, anywhere in Petersfinger you are.

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

Work through the following in order, first.

- Pull your keys out. Even the ignition on its own can prime the system, pulling petrol out of your tank to exactly the components it damages, so keep the vehicle off wholly.

- A bigger tank of the same mix is all topping up leaves you, since it removes nothing. So no more diesel.

- Visibility comes before the rest near moving traffic: put your hazards on, and only then deal with everything else.

- The staff will usually help you push it clear of the pump. Let them, then move it by hand — never under the engine, even for a few yards.

- Hold on to your receipt: the grade and roughly how much are printed on it, and they are what our engineers ask for first.

If you were still on the move when you realised, stop somewhere sensible instead of pushing on for the services — on the M27, under 15 miles from Petersfinger, that means the next junction. Step one follows.

## Every Petersfinger fuel drain starts here: has your engine run?

Everything after this stage depends on one answer.

If the engine hasn't run at all:

- Just your tank has petrol in it for now.

- Usually it's drained and cleaned just where the car stands.

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

Run at all, even for a second:

- The fuel lines and the fuel filter now hold petrol pulled from that tank.

- Run it further and that petrol gets to the fuel injectors, having passed through your pump first.

- Flushing the lines, your filter seen to, and sometimes more: this job grows as the miles does.

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

Petrol sitting in a tank harms nothing.

Petrol being pumped is grinding down the components that shift the car.

## Calling about petrol in a diesel from Petersfinger: what to have ready

A technician that circles against a technician that finds you: a little planning is what separates them.

- Where you are. A postcode beginning SP5 3 is the best place to start.

- The street or the car park. A road name is a help — Petersfinger Road, or wherever you have stopped.

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

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

- What was put in. Petrol, or AdBlue. AdBlue is a different job with its own page for Petersfinger, and so tell us which.

- Roughly how much — in litres from your receipt, or by how long the nozzle stayed in.

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

- The owner may have to approve this work under some hire and company contracts — which is why it is faster to settle whose motor it is before our technicians arrive.

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

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

In the wait, the damage comes from well-intended help — so these count.

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

- A kind passer-by does not start it. Nor does anybody wanting to check it still does the trick, or moving it a few yards.

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

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

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

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

- Three queries. What was put in, how much, and whether it's run. The answers shape this job, which is why the quote comes after them but not before.

- The tank is cleared. The polluted blend comes from your tank.

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

- Where the car has a usable filter, it's replaced; otherwise, cleared.

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

- First start on new diesel. Once priming is done, the motor is started and our technicians check that it runs smoothly.

The car has new diesel running through it before we head off.

Lasting damage is very uncommon if it has been caught quickly, so the car can go straight back to normal driving.

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

- Started on new diesel, it asks nothing special of you. Just drive normally.

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

- An insurer, a fleet manager or a hire company may ask what was carried out, and so hold on to your paperwork.

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