# Heyside: Petrol in a Diesel Car? Here Is What Happens

Stop. Engine off. Keep it like that — no moment on, no moving it at all.

Hasn't been run? Then petrol in a diesel will usually be a straightforward drain-and-flush job wherever the vehicle has stopped — and no other factor settles that as much as these next few minutes do.

From now on, step by step, wherever you are around Heyside:

## Petrol in a diesel, motor off — the first minute

First, the following — in this sequence.

- Priming your fuel system draws petrol from your tank toward the components it damages, and turning your ignition on can be all it takes to do that. So your keys come out, and your ignition remains off completely.

- Do not top it up with diesel. Adding diesel takes out nothing. You end up with a bigger tank of the same mixture.

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

- By hand, not on your engine: that's how it comes off the petrol pump. Get the forecourt attendants to help you push, whatever the miles.

- Keep the receipt: the fuel and the rough amount are written on it, and they're what our technicians ask for first.

Realised on the move? Get off at the next exit if you are on the A627(M), under 3 miles from Heyside, and stop somewhere sensible — not at the services further on. Step one comes after that.

## Every Heyside fuel drain starts here: has your engine run?

Everything after this point rests on one answer.

Not run, not even once:

- Only your tank has petrol in it for now.

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

- Being here is as good as it gets — which is the entire point of stage one.

If it has been started, even for a second:

- Out of the tank, past the fuel filter, into the lines: that's how far that petrol has travelled.

- Your high-pressure pump and your injectors get it on a longer run.

- Lines flushed, your filter seen to, occasionally more: the job grows as the distance does.

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

Petrol resting in a tank damages nothing.

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

## Before you call about petrol in a diesel around Heyside: what our technicians need

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

- Where you have stopped. A postcode beginning OL2 6 is the best place to start.

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

- Or the nearest landmark. A car park is easier to find by what it serves, like the one at The Co-operative Food.

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

- Petrol or AdBlue? Tell us which. They are different jobs, and AdBlue has its own Heyside page.

- Roughly how much — in litres from the receipt, or by how long the nozzle stayed in.

- Whether it has run. Then if it has, how far plus how heavily.

- The owner may have to approve the work under some hire or company agreements — which is why it's faster to settle whose motor it is before we arrive.

Then phone 0333 366 0103. If it can wait — your car is at home and going nowhere —  does the trick too.

## Whilst you wait for a fuel drain around Heyside

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

- Wait with your car if it is safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from 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 the boot. Injector cleaner and two-stroke oil draw none of that petrol out a second time.

- Siphoning petrol into a can by the roadside is hazardous — and it also leaves whatever fuel has already gone beyond your tank. Do not drain the vehicle yourself.

- Ignition remains off. Even for your radio or the windows.

## Step by step: your fuel drain when our van gets there

- The quote comes after three queries, not before them — what went in, how much, and if it's run — since the answers shape this job.

- Next that tank is drained, and the contaminated fuel is taken out.

- Rinsing the lines comes next, since a motor that ran has petrol past your tank, inside the fuel lines themselves.

- Cleaned, or changed if your car has a workable one: your filter is sorted next.

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

- The start-up. With new diesel in and the system primed, it's started and tested to be sure it runs properly.

Your car has clean diesel running through it before our technicians head off.

Your car returns to normal driving right away, and permanent damage is very uncommon when it has been noticed quickly.

## Heyside, after the fuel drain: back on the road

- Drive normally. There's nothing special to do once it's been started on fresh fuel.

- The first miles are the test. A dash warning, exhaust smoke, a rough idle or a hesitant throttle is your cue to stop then ring us once more.

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

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