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

Stop. Engine off. Leave the car like that — no moment on, no moving it anywhere.

The coming few minutes settle it more than anything else: petrol in a diesel still unrun generally amounts to emptying and flushing, right there.

Here is the sequence of things from now, anywhere you're in The Wrythe.

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

Before anything else, these — in this order.

- Take the keys out. Even the ignition by itself can prime the fuel system, pulling petrol out of your tank to precisely the parts it harms, and so keep it alone wholly.

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

- Close to passing traffic? Then the hazards come on before everything else, so the vehicle is easy to spot.

- Off the pump by hand. On a forecourt, get the staff to help you push the vehicle away from the pump. Don't start the vehicle to shift it, however short the distance.

- Keep your receipt: the grade and the rough amount are printed on it, and they're what we ask for first.

On the M23, under 10 miles from The Wrythe, the next exit is the place to leave the car; elsewhere, the first sensible spot to stop. Do not push on to the services. Then go back to stage one.

## Has it run yet? The fork in every The Wrythe fuel drain

What happens after this rests on one answer, and just one.

Motor not run at all?

- That petrol is still in that tank and nowhere else.

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

- This, here, is the best position to be in, and the reason stage one counts.

If the motor has run, even for a moment:

- Out of the tank, through your filter, into the lines: that's how far that petrol has got.

- On a longer run it has reached the high-pressure fuel pump as well as the fuel injectors.

- Miles is what turns it into a bigger job: flushed lines, a filter seen to, and at times more than that.

Diesel keeps the high-pressure fuel pump and your injectors lubricated as it goes through them. Petrol offers them nothing, and that is why the line is drawn there.

In that tank, left alone, petrol does no harm.

Once it's pumped, petrol starts wearing whatever moves it.

## Calling about petrol in a diesel from The Wrythe: what to have prepared

A technician that circles against a van that finds you: a little preparation is the difference.

- The ideal place to start is a postcode — one beginning SM5 2 — for where you are.

- Give the road — Culvers Avenue or wherever you have pulled up — or the car park.

- Describe a car park by what it serves — the one outside Shilpa's News, for instance — and it's much quicker to find.

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

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

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

- If it has run, how far plus how hard — and whether it has run at all.

- Hire or company car? Some contracts want the owner's go-ahead for this work, and sorting it before our engineers turn up is faster than afterwards.

Call 0333 366 0103 once you have got that ready — or, if the vehicle is at home, going nowhere, use .

## Waiting for a fuel drain in The Wrythe: what to do

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

- Where the vehicle has stopped decides where you wait. Somewhere exposed: away from it, clear of the traffic. Sensible: with it. Either way, safety before the vehicle.

- A helpful passer-by doesn't fire it up. Nor does anybody wanting to check it still works, or moving it a few yards.

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

- Draining it yourself is out: a can of siphoned petrol on a verge is a danger, and the fuel beyond that tank stays where it is anyway.

- Keep the ignition off — your windows and the radio included.

## Step by step: your fuel drain when our van arrives

- Fuel, quantity, whether it's run: those replies set this job, and that's why we give a quote after them instead of before.

- Out of your tank comes the polluted blend: the tank is cleared.

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

- Cleared, or changed if the car has a usable one: the fuel filter is seen to next.

- Fresh diesel in, and your system primed.

- The start. With fresh diesel in and the system primed, it is started and checked to be sure it runs smoothly.

Till it runs on fresh diesel, our technicians stay with it.

It's very uncommon for a vehicle noticed quickly to be left with lasting damage, and normal driving resumes at once.

## The Wrythe, after the fuel drain: back on the road

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

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

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

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

## About The Wrythe itself

The Wrythe is a suburban area in south London, situated near the River Wandle and close to several local centres, including Hackbridge and Beddington Corner. The Wrythe has a mix of housing types, but is predominantly characterised by terraced homes, and its riverside setting gives it a distinctive edge. The Wrythe is located about 9 miles from central London, with Westminster just under 9 miles away. The Wrythe sits at a relatively low elevation of around 32 metres above sea level.

## The Wrythe and nearby: fuel drains across the area

The same vans that take petrol in diesel calls around The Wrythe serve Hackbridge, Beddington Corner and St Helier, and most of Greater London beyond them.

Ring and ask rather than guessing if you are somewhere hard to describe or close to a boundary.

## Ring, and leave it off — petrol in a diesel in Greater London

Engine off. Keys out. Receipt in your pocket. That's the whole of step one, and Petrol in Diesel takes it from there — at the roadside, at the forecourt or on your drive.
