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

Stop. Motor off. Leave the car that way — no second on, no moving it at all.

Hasn't been run? Then petrol in a diesel will usually be a straightforward drain-and-flush job wherever your vehicle has stopped — and nothing settles that as much as these next few minutes do.

From now on, in order, wherever you are around Mole Hill:

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

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

- Ignition off, keys out. Turned on, your ignition can prime the system — and priming is what draws petrol out of your tank into the components it damages.

- Topping up with diesel sounds like it thins the issue. It does not: nothing gets out, and that tank simply carries more of the same.

- Near moving traffic? Then your hazards go on before anything else, and so the car is simple to spot.

- By hand, not on the motor: that's how it comes off the petrol pump. Get the forecourt attendants to help you roll, whatever the distance.

- Which fuel, and about how much? Your receipt answers that, and that is where our first question starts. Don't bin it.

Noticed on the move? Get off at the next exit if you are on the M11, under 25 miles from Mole Hill, and pull over somewhere safe — not at the services further on. Step one comes after that.

## Mole Hill fuel drain: has the engine run yet, or not?

One answer is what everything after this stage depends on.

Motor not run at all?

- All the petrol remains in the tank, and just there.

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

- Being here is as good as it gets — which is the whole point of step one.

If your motor has run, even for a moment:

- The fuel lines and your filter now carry petrol pulled from the tank.

- On a longer run it has got to your high-pressure pump and your injectors.

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

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

Petrol resting in a tank damages nothing.

Move that petrol, though, and it grinds down the very parts that move it.

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

Prepare a little, and the van finds you rather than circling.

- Where you have stopped. A postcode beginning CB8 8 is the ideal start.

- Name the street — Thorns Meadow or wherever you have stopped — or the car park.

- Car parks are found most easily by what they serve: say the one at Clare Co-op, and it's easy.

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

- Say which was put in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Mole Hill.

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

- Whether it has run. Then if it has, how far plus how hard.

- Hire or company car? Some agreements need the owner's go-ahead for this work, and getting it before we turn up is faster than after.

Ring 0333 366 0103 next. Writing to  is fine too if it can wait, with the car parked at home, going nowhere.

## Waiting for a fuel drain in Mole Hill: what to do

The wait is where kindly meant help does the harm. Stick to these.

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

- A kind passer-by doesn't crank it. Nor does anyone wanting to check it still works, or rolling it a few yards.

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

- Siphoning petrol into a can by the kerbside is hazardous — and it still leaves whatever fuel has already gone beyond the tank. Do not try a home-made drain.

- The ignition remains off. Even for the radio or your windows.

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

- First, three queries: which fuel was put in, the amount, and has it run? Those answers shape this job, and so the price follows them.

- Your tank is cleared. The contaminated blend comes from that tank.

- Rinsing your lines comes next, since a vehicle that ran has petrol past that tank, inside the fuel lines themselves.

- Cleared, or replaced if your car has a serviceable one: your filter is sorted next.

- The system is primed with clean diesel.

- Starting up. Once the fuel system is primed with fresh diesel, our technicians start the car and check it runs smoothly.

Until it runs on clean diesel, we stay with it.

The vehicle returns to normal driving at once, and lasting damage is very rare if it has been spotted soon.

## Once the fuel drain is done: driving in Mole Hill once more

- Drive normally. There's nothing special to do once it's been started on fresh fuel.

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

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

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