# What Happens Now: Petrol in a Diesel Car in Old Felixstowe

Stop. Engine off. Keep the vehicle like that — no moment on, no moving it anywhere.

Petrol in a diesel that hasn't been run is normally a drain and a flush, done right where the car sits, and what happens in the coming few minutes decides that far more than anything else.

From now on, in order, wherever you are in Old Felixstowe:

## Petrol in a diesel? What to do in minute one

Work through the following before anything else, in this sequence.

- The keys out of the ignition. Turning your ignition on can be enough to prime the system, while priming pulls petrol out of your tank towards the components it harms. Keep it off completely.

- A fuller tank of the same mixture is all topping up gives you, since it removes nothing. So no extra diesel.

- Near moving traffic? Then the hazards go on before anything else, and so the car is simple to see.

- The attendants will generally help you push it away from the pump. Let them, then move it by hand — never on your engine, even for a few yards.

- Keep the receipt: the fuel and the rough amount are printed on it, and they are what our technicians ask about first.

Still on the move when you realised? Come off the M11 at the next exit if that is where you are, under 50 miles from Old Felixstowe, and stop somewhere safe and not pressing on to the services. Then start at step one.

## Has it run yet? The fork in every Old Felixstowe fuel drain

From this stage on, everything comes down to a single answer.

If your engine hasn't run at all:

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

- The job is a simple drain and a flush, usually done where the vehicle is.

- This is as good as it gets — which is the whole point of stage one.

If it has been started, even for a second:

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

- The high-pressure fuel pump as well as your injectors see it too on a longer run.

- The further it went, the larger this job — your lines, your filter, and sometimes more besides.

The line falls there because diesel protects the high-pressure fuel pump and your injectors on its way through them — and petrol does not.

Petrol resting in a tank harms nothing.

The components that move it are wearing the moment petrol is being pumped.

## Calling about petrol in a diesel from Old Felixstowe: what to have prepared

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

- Where you have stopped. A postcode beginning IP11 9 is the best place to start.

- Name the road — St Georges Road or wherever you have pulled up — or the car park.

- Or the nearest landmark. A car park is quicker to find by what it serves, such as the one at Sainsbury's.

- That it is a diesel, plus the make and model of your vehicle.

- Say which got in — petrol or AdBlue — since AdBlue is a separate job, with a page of its own for Old Felixstowe.

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

- If it has run, how far plus how heavily — as well as whether it's run at all.

- Hire or company car? Some contracts want the owner's go-ahead for the work, and sorting it before our technicians turn up is faster than after.

Then ring 0333 366 0103. If it can wait — your car is at home with going nowhere —  works too.

## While you wait for a fuel drain in Old Felixstowe

Stick to these: well-meant help does the damage during the wait.

- Your safety comes before your car. Somewhere dangerous? Get away from the traffic then wait away from it. Safe where it stands? Stay with it.

- A kind passer-by does not crank it. Nor does anyone wanting to check it still does the trick, or moving it a couple of yards.

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

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

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

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

- Fuel, quantity, whether it has run: the replies decide this job, and that is why you get a price after them instead of before.

- Your tank is drained. The tainted mixture comes out of that tank.

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

- Then the filter: replaced where there is a usable one, cleared where there is not.

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

- First start on new diesel. Once priming is done, your engine is started and we make sure that it runs properly.

Your car has new diesel running through it before we head off.

It's very uncommon for a car caught soon to be left with permanent damage, and normal driving resumes straight away.

## Back on the road in Old Felixstowe after the fuel drain

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

- Give the first miles your attention. Smoke appearing, a warning light coming on, the idle going lumpy or your throttle hesitating: pull over then call us back.

- An insurer, a fleet manager or a hire firm may ask what was done, so keep the documents.

- The handle's colour is not the guide to go by next time — the label on the pump is.
