# Petrol in a Diesel Car in Little Kingshill: What Happens Now

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

Hasn't been run? Then petrol in a diesel tends to be a straightforward drain-and-flush job wherever the car has stopped — and no other factor settles that more than the next few minutes do.

Here's the sequence of things from now, wherever you're around Little Kingshill.

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

Do these before anything else, in this order.

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

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

- Make your car easy to see before anything else — hazards on — if there's moving traffic anywhere near you.

- However short the distance, starting it to move it is the thing to avoid. On a forecourt, roll it away from the petrol pump by hand instead, and ask the staff to lend a hand.

- Keep the till receipt. It shows which fuel got in plus roughly how much, which is the first thing we will ask.

Noticed on the move? Get off at the next exit if you are on the M40, under 10 miles from Little Kingshill, and pull over somewhere sensible — not at the services further on. Step one comes after that.

## Every Little Kingshill fuel drain starts here: has your motor run?

Everything after this stage rests on one answer.

Engine never run at all?

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

- Where your car sits is normally where this work happens: a drain, then a flush.

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

Engine run, however for a moment?

- The lines and your filter already hold petrol drawn from the tank.

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

- The job grows with the miles — lines rinsed, filter seen to, sometimes more.

Petrol doesn't lubricate. Diesel does, oiling the high-pressure pump and injectors as it flows through, which is why the line sits where it does.

In your tank, left alone, petrol harms nothing.

Petrol being pumped is wearing the parts that shift the vehicle.

## What to have prepared when you call about petrol in a diesel from Little Kingshill

A little planning is the difference between a technician that finds you and a van that circles.

- HP16 0 and the remainder of the postcode makes the best way to start telling us where you are.

- Wherever you have pulled up, the road's name helps — whether that's St. Christopher's Close or somewhere else — and so does the name of a car park.

- Car parks are located most easily by what they serve: tell us the one at The Co-operative Food, and it is simple.

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

- What was put in. Petrol, or AdBlue. AdBlue is a different job with its own page for Little Kingshill, and so say which.

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

- Whether it's run. And if it has, how far plus how hard.

- The owner may have to approve this work under some hire or company contracts — so it is quicker to settle whose motor it is before our technicians get there.

Then call 0333 366 0103. If it can wait — the vehicle is at home with going nowhere —  does the trick as well.

## Little Kingshill fuel drain on its way? While you wait

The wait is where kindly meant help does the damage. Hold to these.

- Your safety comes before your car. Somewhere unsafe? Get away from the traffic then wait away from it. Safe where it is? Wait with it.

- A helpful passer-by does not start it. Nor does anybody checking it still works, or moving it a couple of yards.

- Anything from the boot, oil meant for two-strokes or injector cleaner: no additive lifts the petrol.

- No DIY clearing. Siphoning petrol into a can by the roadside is risky, and it leaves your fuel that has already gone beyond that tank.

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

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

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

- Then that tank is cleared, and the polluted fuel comes out.

- Petrol that has shifted beyond your tank sits in the fuel lines if it ran, and the fuel lines are flushed to clear it.

- Cleaned, or swapped if your car has a usable one: the fuel filter is sorted next.

- Fresh diesel in, and your system primed.

- Starting up. Once the fuel system is bled with fresh diesel, we start the car and make sure it runs smoothly.

Your car has new diesel running through it before our technicians go.

Long-term damage is very rare if it has been spotted quickly, so your car can go right back to normal use.

## Back on the road around Little Kingshill after the fuel drain

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

- Pull over and ring us back if anything seems wrong early on — a light on your dash, smoke from your exhaust, an idle that runs rough, or a throttle with a dead spot.

- The work may matter later with a hire firm, an insurer or a fleet manager. Keep your documents.

- The handle's colour is not the guide to go by next time — the label on the petrol pump is.
