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

Not for a second, and not to move it: your motor remains off. Pause there.

Has not been run? Then petrol in a diesel tends to be a straightforward drain-and-flush job wherever the vehicle has stopped — and no other factor settles that more than these next few minutes do.

Here is the order of things from now, wherever you are in Old Whittington.

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

Go through the following in order, before you do anything else.

- The keys out of the ignition. Turning your ignition on can be all it takes to prime your fuel system, and priming pulls petrol out of the tank toward the parts it damages. Leave the vehicle off altogether.

- Topping up with diesel seems like it thins the issue. It does not: nothing comes out, and that tank just carries more of the same.

- Visibility comes first near moving traffic: put your hazards on, and only then deal with everything else.

- However short the distance, starting it to shift it is the thing to avoid. At a forecourt, push the vehicle away from the petrol pump by hand instead, then ask the attendants to help.

- Keep the till receipt. It says which fuel got in plus about how much, which is the first thing we'll ask.

Noticed on the move? Get off at the next exit if you're on the M1, under 5 miles from Old Whittington, and pull over somewhere sensible — not at the services farther on. Step one comes after that.

## Has it run yet? The fork in each Old Whittington fuel drain

What comes after this turns on one answer, and only one.

If the motor hasn't run at all:

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

- Where the car sits is usually where this work is done: a drain, then a flush.

- Being here is the best case — which is the whole point of stage one.

If the motor has run, even briefly:

- Some petrol has left the tank already, passed through your filter, and got into the lines.

- On a longer run it has reached the high-pressure pump and your injectors.

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

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

Petrol resting in a tank damages nothing.

Petrol being pumped is grinding down the components that move the vehicle.

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

Get ready a little, and the van finds you instead of circling.

- Your location: a postcode beginning S41 9 works best.

- Give the street — High Street or wherever you have pulled up — or the car park.

- Or the landmark. A car park is easier to find by what it serves, like the one outside Lidl.

- Tell us what your vehicle is — make, model — and check it is diesel.

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

- About how much — in litres from the receipt, or by how long the nozzle was in.

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

- Whose motor it is. Some hire or company contracts want the owner to approve this work, and that is easier settled before our engineers turn up than after.

Ring 0333 366 0103 next. Writing to  is fine too if it can wait, with your car parked at home, going nowhere.

## Old Whittington fuel drain on its way? While you wait

Stick to these: kindly meant help causes the damage during the wait.

- Safety before the vehicle. If it has stopped somewhere exposed, get yourself clear of the traffic and wait away from it. If it's safe where it stands, stay with it.

- A kind passer-by doesn't start it. Nor does anybody checking it still works, or moving it a few yards.

- None of that takes that petrol back out — not two-stroke oil, not injector cleaner, not something from the boot. So no additives.

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

- Keep your ignition off — the windows and the radio too.

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

- Fuel, amount, whether it's run: those answers set the job, and that's why we give a price after them rather than before.

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

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

- The fuel filter is sorted. Cleared, or replaced where the vehicle has a workable one.

- Bleeding the system comes after clean diesel is in.

- The start. With clean diesel in and your system primed, it's started and tested to confirm it runs smoothly.

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

Long-term damage is very uncommon if it has been spotted early, so your car can go straight back to normal driving.

## Old Whittington, after the fuel drain: back on the road

- Nothing special is needed after a start with fresh diesel — usual driving will do.

- Watch the first miles. A warning light, smoke, a lumpy idle or a flat spot under the throttle means pull over then call us back.

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

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