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

Stop, then keep your engine off — not on, and not for a moment to move the car.

Emptied then purged, just where it sits: that's usually all an unrun diesel with petrol in it takes. Whether it remains that simple rests on the minutes ahead far more than on everything else.

What follows is the sequence from this point, anywhere around Barby you happen to be.

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

In this sequence, all before everything else:

- Bleeding the fuel system pulls petrol from your tank toward the components it damages, and switching the ignition on can be all it takes to do that. So the keys come out, and your ignition remains off altogether.

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

- Hazards on. If you are at all close to moving traffic, make the car simple to see before you do anything else.

- By hand, never on your engine: that is how it comes off the pump. Ask the forecourt staff to help you push, whatever the miles.

- Hold on to the till receipt. It shows which fuel went in and roughly how much, which is the first thing we'll ask.

Still on the move when you noticed? Come off the M45 at the next exit if that is where you are, under a mile from Barby, and stop somewhere safe instead of pushing on to the services. Then start at step one.

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

Everything after this point depends on one answer.

Motor never run at all?

- All the petrol remains inside that tank, and only there.

- A drain and flush, on the spot, is normally all of that.

- This is the best case — which is the whole point of step one.

If it has been started, even for a moment:

- Your lines and your filter now carry petrol pulled out of your tank.

- The high-pressure pump and your injectors see it too on a bigger run.

- The job expands with the mileage — lines rinsed, filter sorted, sometimes more.

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

A tank of petrol, left alone, damages nothing.

Move the petrol, though, and it grinds down the very parts doing the moving.

## What to have ready when you call about petrol in a diesel from Barby

A technician that circles against a technician that finds you: a little preparation is what separates them.

- Your whereabouts: a postcode beginning CV23 8 works best.

- The street or the car park. A road name helps — The Green, or wherever you have pulled up.

- Car parks are found more easily by what they serve: say the one at Co-op Food, and it's easy.

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

- Which got in matters: AdBlue is a separate job from petrol, and Barby has a page just for that. So say.

- How long the nozzle was in, or the litres on your receipt — either tells us how much.

- If it has run, how far plus how hard — as well as if it has run at all.

- Whose vehicle it is. Some hire and company agreements want the owner to authorise this work, and that is quicker settled before our technicians get there than after.

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

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

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

- Your safety comes before your car. Somewhere unsafe? Get away from the traffic and wait away from it. Safe where it stands? Stay 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 couple of yards.

- Additives remain in the boot. Injector cleaner and two-stroke oil draw none of that petrol out once more.

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

- The ignition stays off. Even for the radio or the windows.

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

- Three questions. What got in, how much, and whether it's run. The replies set this job, which is why our quote comes after them and not before.

- Out of your tank comes the polluted mixture: your tank is drained.

- Your lines are rinsed. If it ran, that petrol has shifted beyond that tank, and the lines are holding it.

- Your filter is seen to. Cleared, or swapped where the vehicle has a serviceable one.

- The system is primed with fresh diesel.

- Starting the car. Once the system is primed with clean diesel, our engineers start the engine and confirm it runs smoothly.

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

When it has been spotted soon, lasting damage is very uncommon, and the car returns to normal driving right away.

## Barby, after your fuel drain: back on the road

- Once it has been started on fresh fuel, there is nothing special to do: drive normally.

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

- Keep the paperwork. A hire company, a fleet manager or an insurer may ask what was carried out.

- Next time, go by the petrol pump's label rather than the colour of its handle.
