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

Whatever you do, don't switch the motor on, even for a moment, to move the car. Pause; leave the vehicle off.

Has not been run? Then petrol in a diesel tends to be a simple drain-and-flush job wherever the car has stopped — and nothing settles that more than the next few minutes do.

Anywhere you are around Pilning, here is how things go from now.

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

In this order, and before anything else:

- Ignition off, keys out. Switched on, your ignition can prime your system — and priming is what moves petrol out of the tank into the parts it damages.

- Don't top it up with diesel. Adding diesel removes nothing. You are left with a bigger tank of the same mix.

- Hazards on. If you're anywhere near moving traffic, make your car easy to see before you do anything else.

- Off the pump by hand. At a forecourt, get the attendants to help you push the car away from the petrol pump. Do not start the car to shift it, however short the distance.

- The first thing we will ask is which fuel went in and about how much — and the receipt says both. Keep it.

Noticed on the move? Get off at the next exit if you are on the M4, under a mile from Pilning, and pull over somewhere safe — not at the services further on. Stage one comes after that.

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

Everything after this stage rests on one answer.

If your motor hasn't run at all:

- No place but the tank: that is where the petrol still is.

- Draining and flushing, on the spot, is normally the whole job.

- No place is better, and it is why the first stage matters so much.

Run at all, however briefly:

- Some petrol has left your tank by now, gone through the filter, and got into your lines.

- Run it further and the petrol reaches the fuel injectors, having passed through your pump first.

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

Petrol doesn't lubricate. Diesel does, oiling your pump and injectors as it flows through, which is why the line sits where it does.

Petrol sitting in a tank damages nothing.

Move that 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 Pilning

A little preparation is the difference between a technician that finds you and a van that circles.

- The ideal place to start is a postcode — one beginning BS35 4 — for where you are.

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

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

- The make and model of your vehicle, and the fact it is a diesel.

- Tell us which got in — petrol or AdBlue — because AdBlue is a separate job, with a page of its own for Pilning.

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

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

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

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

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

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

- Safety before your car. If it has stopped somewhere unsafe, get yourself clear of the traffic and wait away from it. If it is safe where it stands, stay with it.

- Not to roll it a couple of yards, not to check it is all right, not for a passer-by's favour: nobody starts it.

- No additives. Two-stroke oil, injector cleaner, something from your boot — none of that takes the petrol back out.

- No DIY emptying. Siphoning petrol into a can at the kerbside is risky, and it leaves the fuel that has already gone beyond your tank.

- Even your radio or the windows are not worth turning your ignition on for.

## Van arrived? The fuel drain, one step at a time

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

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

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

- Where your car has a workable filter, it's swapped; otherwise, cleared.

- Bleeding the system follows after clean diesel is in.

- The first start on clean diesel. When priming is complete, the motor is fired up and our technicians confirm that it runs correctly.

The vehicle has new diesel running through it before our engineers go.

Your car returns to normal driving right away, and long-term damage is very uncommon if it has been caught early.

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

- Once it's been started on clean 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 tells you to pull over and ring us back.

- An insurer, a fleet manager or a hire firm may ask what was carried out, so hold on to your documents.

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

## Fuel drains around Pilning and beyond

## Petrol in a diesel anywhere in Gloucestershire? Off, then ring

Motor off. Keys out. Receipt in your pocket. That is the whole of stage one, and Petrol in Diesel takes it from there — by the roadside, at the forecourt or on your driveway.
