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

Pause, then leave the engine off — not on, and not for a second to move the car.

Emptied then purged, right where it sits: that is generally all an unrun diesel with petrol in it takes. Whether it stays that simple rests on the minutes ahead more than on everything else.

Below is the sequence from here, wherever around Tandlehill you happen to be.

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

Before anything else, these — following this order.

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

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

- Hazards on. If you're anywhere close to moving traffic, make the vehicle simple to see before you do anything else.

- By hand, never under the engine: that is how it leaves the petrol pump. Ask the forecourt attendants to help you roll, whatever the mileage.

- Which fuel, and roughly how much? The receipt replies both, and that's where our questions start. Do not bin it.

Still driving when you noticed? Come off the M8 at the next exit if that's where you are, under 5 miles from Tandlehill, and stop somewhere safe rather than pressing on to the services. Then begin at step one.

## Every Tandlehill fuel drain starts here: has the motor run?

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

If it has never been started:

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

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

- No position is better, and it is why the first step counts so much.

Run at all, even for a second:

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

- A bigger run takes it right through to your high-pressure pump and your injectors.

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

The line falls there because diesel lubricates the high-pressure fuel pump and your injectors on its way through them — and petrol doesn't.

Petrol resting in a tank damages nothing.

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

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

Prepare a little, and the technician finds you instead of circling.

- Where you are. A postcode beginning PA10 2 is the ideal place to start.

- The road or the car park. A road name is a help — Toppersfield, or wherever you have stopped.

- What a car park serves is the quickest way to find it, and so say the landmark — like the one at Aldi.

- The car. Make, model, plus that it is a diesel.

- Petrol or AdBlue? Say which. They are different jobs, and AdBlue has a separate Tandlehill page.

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

- The mileage it covered, and how heavily, if it ran at all.

- The owner may have to approve this work under some hire and company contracts — which is why it's quicker to settle whose motor it is before we get there.

Ring 0333 366 0103 once you have got that together — or, if your car is at home, going nowhere, use .

## Whilst you wait for a fuel drain around Tandlehill

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

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

- Nobody — however helpful — starts it, whether to see if it runs or to shift the vehicle a short way.

- Additives remain in the boot. Injector cleaner and two-stroke oil take none of that petrol out a second time.

- Draining it yourself is out: a can of siphoned petrol on a verge is a danger, and your fuel beyond the tank stays where it is anyway.

- Even your radio or your windows aren't worth turning your ignition on for.

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

- The price comes after three questions, not before them — what was put in, how much, and whether it's run — because the answers shape this job.

- Out of that tank comes the contaminated mixture: your tank is cleared.

- If it ran, the fuel lines are holding petrol that has shifted beyond the tank — so they are flushed.

- Where your car has a serviceable filter, it is replaced; otherwise, cleared.

- Clean diesel in, and your system primed.

- The start. With fresh diesel in and your system primed, it is started and tested to be sure it runs properly.

The vehicle has new diesel running through it before our technicians head off.

If it has been noticed early, lasting damage is very unusual, and the car goes back to normal use at once.

## After your fuel drain: back on the road in Tandlehill

- Nothing unusual is needed after a start with clean diesel — usual driving is all.

- Keep an eye on the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle tells you to pull over then call us back.

- Hold on to the paperwork. A hire company, a fleet manager or an insurer may ask what was done.

- Next time, trust the petrol pump's label rather than the colour of its handle.
