# What Happens Now: Petrol in a Diesel Car in Mayers Green

Stop. Engine off. Keep the vehicle like that — no second on, no shifting it at all.

The coming few minutes determine it more than anything else: petrol in a diesel still unrun usually amounts to draining then purging, right there.

Wherever you happen to be in Mayers Green, here is how things run from now.

## Engine off: minute one with petrol in a diesel

Do the following first, in this sequence.

- Priming the fuel system draws petrol from the tank toward the components it harms, and turning the ignition on can be enough to do that. So your keys get taken out, and the ignition stays off altogether.

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

- Visibility comes first near moving traffic: put the hazards on, and only then deal with anything else.

- Off the pump by hand. At a forecourt, ask the staff to help you roll it away from the pump. Do not start it to move it, however short the way.

- Keep the receipt. It says which fuel was put in and about how much, which is the first thing we'll ask.

On the M5, under a mile from Mayers Green, the next junction is the place to come off; anywhere, the first sensible spot to stop. Do not push on to the services. Then go back to step one.

## Each Mayers Green fuel drain starts here: has the motor run?

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

If it has not once been started:

- That petrol is still inside your tank and nowhere else.

- The job is a simple drain and a flush, normally done where your car stands.

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

If it's been started, even for a second:

- Petrol has been pulled out of the tank, through the fuel filter then into your lines.

- The high-pressure fuel pump and the fuel injectors get it on a bigger run.

- The job expands with the distance — lines purged, filter sorted, sometimes more.

The reason the line falls there: diesel protects the high-pressure fuel pump and the fuel injectors as it passes through them, and petrol does not.

Petrol sitting in a tank damages nothing.

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

## Mayers Green, petrol in a diesel: have these prepared before you call

Get ready a little, and the van finds you instead of circling.

- B71 4 plus the remainder of the postcode is the ideal way to begin telling us where you are.

- A road name is a help: Park Crescent, say, or whichever street you have stopped in. A car park does the trick too.

- What a car park serves is the quickest way to find it, so mention the landmark — like the one outside Tesco Extra.

- Make and model of your car, and the fact it is a diesel.

- Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has a separate Mayers Green page.

- How long the nozzle was in, or the litres on the receipt — whichever gives us how much.

- Has it run? If so, tell us how far it got, and the way it was driven.

- Hire or company car? Some agreements need the owner's go-ahead for the work, and getting it before our engineers arrive is quicker than after.

Call 0333 366 0103 next. Writing to  is fine too if it can wait, with your car left at home, going nowhere.

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

During the wait, the damage comes from well-intended help — so these count.

- Your safety comes before your car. Somewhere dangerous? Get away from the traffic and wait away from it. Fine where it stands? Wait with it.

- No one starts it. Not a passer-by being helpful, not to check it is all right, not to roll the car a few yards.

- Additives remain in your boot. Injector cleaner and two-stroke oil take none of the petrol out a second time.

- A home-made drain misses the fuel that has already gone beyond that tank, and siphoning petrol by the road is hazardous besides.

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

## The fuel drain, step by step, after our van gets there

- The price comes after three questions, not before them — what was put in, how much, and whether it has run — since those replies set this job.

- Clearing it is how that mixture gets taken from the tank.

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

- Your filter is seen to. Cleared, or replaced where the car has a workable one.

- Bleeding the system comes once fresh diesel is in.

- First start on new diesel. Once bleeding is finished, your engine is started and we make sure that it runs correctly.

Our technicians stay until it is running on new diesel.

If it has been spotted early, long-term damage is very unusual, and your car goes back to normal use right away.

## Back on the road around Mayers Green after your fuel drain

- Started on clean diesel, it needs nothing special of you. Just drive normally.

- Keep an eye on the first miles. A warning light, smoke, a rough idle or a flat spot under your throttle tells you to pull over and ring us back.

- Keep the documents. A hire company, a fleet manager or an insurer may ask what was done.

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