# What Happens Now: Petrol in a Diesel Car in Colebrook

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

Has not been run? Then petrol in a diesel will usually be a simple drain-and-flush job wherever your vehicle has stopped — and no other factor decides that more than these next few minutes do.

From here on, in order, for anywhere around Colebrook:

## Minute one: petrol in a diesel, engine off

Work through the following in sequence, before you do anything else.

- The keys out of the ignition. Switching your ignition on can be all it takes to prime your fuel system, while priming pulls petrol out of your tank toward the parts it harms. Keep it off altogether.

- No diesel on top. More fuel in removes none of that petrol — it only makes you with more of the same mixture.

- Being seen comes before the rest near moving traffic: put the hazard lights on, and only then think about anything else.

- Off the petrol pump by hand. On a forecourt, get the staff to help you roll the vehicle away from the petrol pump. Don't fire it up to shift it, however short the way.

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

On the M5, under 50 miles from Colebrook, the next exit is the place to leave the car; elsewhere, the first safe location to stop. Don't push on to the services. Then go back to step one.

## Colebrook fuel drain: has the engine run yet, or not?

What comes after this turns on one answer, and just one.

Not run, not even briefly:

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

- The work is a simple drain and a flush, normally done where the car stands.

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

Run at all, however briefly:

- Your lines and the fuel filter already hold petrol pulled from that tank.

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

- Mileage is what turns it into a bigger job: the lines flushed, a filter seen to, and at times further work.

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

Petrol resting in a tank harms nothing.

Once it is pumped, petrol starts wearing whatever moves it.

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

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

- Your whereabouts: a postcode beginning PL7 4 works best.

- Wherever you have parked, the road's name is useful — whether that is Hemerdon Way or somewhere else — and so does the name of a car park.

- Car parks are found most easily by what they serve: tell us the one at Aldi, and it is straightforward.

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

- Say which got in — petrol or AdBlue — because AdBlue is a different job, with a page of its own for Colebrook.

- The amount: your receipt's litres, or else how long you had the nozzle in.

- The distance it did, and how heavily, if it ran at all.

- Hire or company car? Some agreements need the owner's go-ahead for this work, and sorting it before our technicians get there is quicker than after.

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

## Colebrook fuel drain on its way? While you wait

Hold to these: kindly meant help causes the damage during the wait.

- Safety before the vehicle. If it has stopped somewhere dangerous, get yourself away from the traffic then wait away from it. If it's safe where it stands, wait with it.

- Nobody — however kind — starts it, whether to see if it runs or to move the car a short way.

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

- No home-made draining. Siphoning petrol into a can at the kerbside is risky, and it leaves your fuel that has by now gone beyond the tank.

- Leave the ignition off — your windows and your radio too.

## When our van arrives: your fuel drain, step by step

- Three queries. What was put in, how much, and if it has run. The answers shape this job, which is why our quote comes after them and not before.

- That tank is drained. The tainted mix comes from your tank.

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

- Where your car has a usable filter, it is changed; if not, cleared.

- Priming follows once clean diesel is in.

- The start-up. With clean diesel in and your system primed, it's started and tested to make sure it runs properly.

Until it runs on clean diesel, our engineers remain with it.

It is very rare for a vehicle noticed soon to be left with long-term damage, and normal use resumes right away.

## Back on the road in Colebrook after your fuel drain

- Once it's been started on fresh fuel, there's nothing unusual to do: drive normally.

- Keep an eye on the first miles. A warning light, smoke, a rough idle or a flat spot under the throttle means pull over then call us back.

- An insurer, a fleet manager or a hire company may ask what was done, and so hold on to the documents.

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