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

Whatever you do, never switch the motor on, even briefly, to move it. Stop; leave the car off.

The next few minutes decide it more than anything else: petrol in a diesel still unrun generally amounts to emptying and purging, on the spot.

Here is the order of things from here, wherever you're around Bassett.

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

Go through the following in order, first.

- Pull your keys out. Even your ignition on its own can prime the fuel system, pulling petrol out of the tank to precisely the parts it harms, and so leave the vehicle alone entirely.

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

- Visibility comes before the rest beside moving traffic: put the hazards on, and only then think about anything else.

- The staff will generally help you roll it clear of the pump. Let them, and roll it by hand — not under your engine, even for a few yards.

- Which fuel, and about how much? Your receipt answers that, and that's where our first question starts. Don't throw it away.

If you were still on the move when you realised, pull over somewhere sensible rather than pushing on for the services — on the M27, under a mile from Bassett, that means the next exit. Stage one follows.

## Each Bassett fuel drain starts here: has your motor run?

Everything after this stage depends on one answer.

If the motor hasn't run at all:

- The petrol remains in the tank, and only there.

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

- Stage one matters for exactly this reason: it is the best position to be in.

If it has been started, even for a second:

- Your lines and the fuel filter already hold petrol drawn out of that tank.

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

- Distance is what makes it a larger job: the lines flushed, a filter seen to, and at times further work.

Petrol does not lubricate. Diesel does, protecting your pump and injectors as it flows through, which is why the line sits where it does.

In the tank, sitting still, petrol harms nothing.

As soon as it's pumped, petrol begins wearing whatever moves it.

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

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

- Your location: a postcode beginning SO16 3 serves best.

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

- Car parks are found most easily by what they serve: say the one outside Co-op Food, and it's simple.

- That it's a diesel, plus the make and model of the vehicle.

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

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

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

- Whose vehicle it is. Some hire or company agreements want the owner to approve the work, and that is easier settled before our engineers get there than after.

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

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

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

- Stay with your car if it's safe where it is — but if it has stopped somewhere unsafe, you come first: away from the traffic, waiting apart from it.

- No one — however kind — starts it, whether to see if it runs or to shift your car a short way.

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

- Siphoning petrol into a can by the roadside is dangerous — and it also leaves whatever fuel has already gone beyond that tank. Don't drain the car yourself.

- Not for your radio, not for the windows: the ignition remains off.

## The fuel drain, step by step, after our van arrives

- First, three questions: which fuel was put in, the quantity, and has it run? Those answers decide this job, so our quote follows them.

- Out of the tank comes the tainted mix: the tank is drained.

- Cleaning your lines follows, since a motor that ran has petrol past the tank, in the fuel lines themselves.

- Cleaned, or replaced if the car has a serviceable one: the filter is sorted next.

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

- The start. With clean diesel in and the fuel system primed, it is started and tested to be sure it runs smoothly.

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

Long-term damage is very uncommon if it has been noticed quickly, so the car can go straight back to normal driving.

## After the fuel drain: back on the road around Bassett

- Drive normally. There is nothing unusual to do after it has been started on fresh fuel.

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

- An insurer, a fleet manager or a hire company may ask what was done, so keep your paperwork.

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