# The Next Steps, in Order: Petrol in a Diesel Car in Colts Green

Whatever you do, don't switch your engine on, even for a moment, to shift the vehicle. Stop; leave it off.

The next few minutes decide it more than anything else: petrol in a diesel that has not run generally comes down to emptying then purging, on the spot.

What follows is the order from this point, wherever around Colts Green you happen to be.

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

In this sequence, and before everything else:

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

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

- Being seen comes before the rest near moving traffic: put the hazard lights on, and only then deal with everything else.

- The attendants will generally help you roll it away from the pump. Let them, then roll it by hand — not under the motor, even for a couple of yards.

- The first question we will ask is which fuel you put in and about how much — and your receipt says both. Hold on to it.

Realised on the move? Get off at the next exit if you are on the M4, under 3 miles from Colts Green, and pull over somewhere safe — not at the services further on. Stage one starts after that.

## The fork in every Colts Green fuel drain: has it run yet?

From this point on, everything hinges on a single answer.

Not run, not even briefly:

- Just the tank has petrol in it so far.

- Where your car stands is usually where this work is done: a drain, then a flush.

- No spot is better, and it is why the first step counts so much.

If the engine has been run, even briefly:

- Petrol has been pulled from that tank, through the fuel filter then into the lines.

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

- The further it went, the larger the job — the fuel lines, your filter, and now and then more besides.

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

Petrol sitting in a tank damages nothing.

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

## Before you call about petrol in a diesel around Colts Green: what our engineers need

A little preparation is the difference between a van that finds you and a technician that goes round.

- The ideal place to start is a postcode — one starting BS37 6 — for where you are.

- Give the road — Badminton Road or wherever you have pulled up — or the car park.

- Or the landmark. A car park is easier to find by what it serves, such as the one outside Waitrose.

- That it is a diesel, along with the make and model of your car.

- Which was put in matters: AdBlue is a separate job from petrol, plus Colts Green has a page just for that. So tell us.

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

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

- Whose car it is. Some hire and company agreements want the owner to authorise this work, and that is quicker settled before our engineers arrive than after.

Ring 0333 366 0103 once you've got that together — or, if the vehicle is at home, going nowhere, use .

## Colts Green fuel drain on its way? Whilst you wait

Help, however well meant, is what does the harm whilst you wait. So hold to these.

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

- Nobody starts it. Not a passer-by being helpful, not to check it is all right, not to roll the vehicle a couple of yards.

- Something from the boot, oil made for two-strokes or injector cleaner: no additive removes the petrol.

- Siphoning petrol into a can at the kerbside is risky — and it still leaves whatever fuel has already gone beyond that tank. Do not drain the vehicle yourself.

- Leave the ignition off — the windows and the radio included.

## When our van gets there: your fuel drain, step by step

- Fuel, quantity, whether it's run: those answers set this job, and that is why we give a price after them rather than before.

- Your tank is cleared. The polluted mix comes from your tank.

- Cleaning the lines follows, since a car that ran has petrol past your tank, in the fuel lines themselves.

- Your filter is sorted. Cleared, or changed where the vehicle has a usable one.

- Your system is primed on fresh diesel.

- First start on new diesel. When bleeding is complete, your engine is fired up and our engineers make sure that it runs properly.

The vehicle has new diesel running through it before our engineers leave.

Permanent damage is very unusual when it has been caught soon, so your car can go straight back to normal use.

## Once the fuel drain is done: driving around Colts Green again

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

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

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

- Read the label on the petrol pump next time, not the colour of its handle.
