# Petrol in a Diesel Car in Raynes Park: What Happens Now

Pause, then leave the motor off — not on, and not for a second to shift it.

Has not been run? Then petrol in a diesel will usually be a simple drain-and-flush job wherever the vehicle has stopped — and nothing settles that more than these next few minutes do.

From here on, in order, wherever you are around Raynes Park:

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

Before anything else, the following — in this order.

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

- No diesel on top. More fuel in removes none of the petrol — it just leaves you with extra of the same blend.

- Visibility comes first beside moving traffic: put the hazard lights on, and only then think about anything else.

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

- Keep your receipt. It says which fuel went in and about how much, which is the first thing we will ask.

On the M4, under 10 miles from Raynes Park, the next junction is the spot to come off; anywhere, the first sensible location to stop. Don't push on to the services. Then go back to stage one.

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

One answer is what everything after this stage rests on.

Engine never run at all?

- Just that tank has petrol in it for now.

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

- Being here is the best case — which is the entire point of stage one.

Engine run, however briefly?

- Out of the tank, past your filter, into the lines: that is how far the petrol has travelled.

- The high-pressure fuel pump as well as your injectors get it on a longer run.

- Flushing the lines, your filter sorted, occasionally more: this job expands as the miles does.

The line falls there since diesel lubricates the high-pressure pump and the fuel injectors on its way through them — and petrol does not.

In that tank, left alone, petrol harms nothing.

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

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

Whether the technician goes round or finds you depends on a little preparation.

- Where you have stopped. A postcode beginning SW20 9 is the ideal place to start.

- The road or the car park. A road name helps — West Barnes Lane, or wherever you have pulled up.

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

- That it's a diesel, along with the make and model of the vehicle.

- What got in. Petrol, or AdBlue. AdBlue is a separate job with its own page for Raynes Park, so tell us which.

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

- The mileage it covered, and how hard, if it has run at all.

- The owner may have to authorise this work under some hire or company agreements — which is why it's quicker to settle whose motor it is before our engineers arrive.

Then phone 0333 366 0103. If it can wait — the car is at home and going nowhere —  works as well.

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

Help, however well meant, is the thing that does the damage while you wait. So stick to these.

- Safety before your car. If it has stopped somewhere dangerous, get yourself clear of the traffic and wait away from it. If it is safe where it is, stay with it.

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

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

- Siphoning petrol into a can at the kerbside is risky — and it also 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.

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

- The price comes after three questions, not before them — what was put in, how much, and if it has run — because the answers set the job.

- Out of that tank comes the contaminated mix: your tank is drained.

- If it ran, your lines are carrying petrol that has shifted beyond your tank — so they are rinsed.

- Cleared, or swapped if the vehicle has a workable one: the filter is dealt with next.

- Clean diesel goes in, and the system is primed.

- Our engineers start the engine only after new diesel has gone in and bled your system, then confirm that it's running correctly.

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

The car goes back to normal use at once, and permanent damage is very rare when it has been noticed soon.

## Raynes Park, after your fuel drain: back on the road

- Nothing unusual is needed after a start with clean diesel — normal driving will do.

- The first miles are the test. A warning lamp, exhaust smoke, a rough idle or a flat throttle is your signal to stop then call us a second time.

- An insurer, a fleet manager or a hire firm may ask what was done, and so keep the paperwork.

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