# The Next Steps, in Order: Petrol in a Diesel Car in Tannochside

Pause, and leave the engine off — not on, and not for a moment to shift the vehicle.

Petrol in a diesel that hasn't been run is typically a simple drain and a flush, done right where the car stands, and what you do in the coming few minutes decides that far more than anything else.

Anywhere you are around Tannochside, here is how things run from here.

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

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

- Bleeding your fuel system pulls petrol from the tank towards the parts it damages, and turning the ignition on can be all it takes to do that. So your keys come out, and the ignition remains off altogether.

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

- Hazard lights on. If you are anywhere near moving traffic, make your car simple to see before you do anything else.

- However short the distance, starting it to move it is the mistake. On a forecourt, roll it clear of the petrol pump by hand instead, and ask the staff to lend a hand.

- Hold on to the till receipt. It says which fuel got in plus roughly how much, which is the first thing we will ask.

Still driving when you noticed? Come off the M74 at the next exit if that is where you are, under a mile from Tannochside, and pull over somewhere sensible instead of pressing on to the services. Then begin at step one.

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

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

Not run, not even once:

- The petrol is still in the tank and nowhere else.

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

- This, here, is the best spot to be in, and the reason step one matters.

Run at all, however briefly:

- Some petrol has left that tank already, gone through the filter, and reached the fuel lines.

- On a longer run it has reached the high-pressure fuel pump as well as the injectors.

- Flushing the lines, your filter dealt with, and sometimes more: this job grows as the distance does.

The reason the line falls there: diesel protects the high-pressure pump as well as the fuel injectors as it flows through them, and petrol doesn't.

In the tank, sitting still, petrol harms nothing.

Petrol being pumped is grinding down the parts that move it.

## Before you call about petrol in a diesel in Tannochside: what we need

Whether the van goes round or finds you depends on a little preparation.

- G71 6 and the remainder of the postcode makes the best way to start telling us where you are.

- A road name helps: Old Edinburgh Road, say, or whichever street you've stopped in. A car park works too.

- Or the landmark. A car park is easier to find by what it serves, such as the one at Scotmid.

- That it's a diesel, along with the make and model of your vehicle.

- Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has its own Tannochside page.

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

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

- Sort who has your car ahead of when we turn up: some hire and company agreements want the owner to approve the work, and doing it quicker first.

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

## Whilst you wait for a fuel drain around Tannochside

Help, however well meant, is what does the damage whilst you wait. So hold to these.

- Where your car has stopped decides where you wait. Exposed: away from it, clear of the traffic. Safe: with it. Either way, safety before the vehicle.

- Nobody — however kind — starts it, whether to see if it runs or to move your car a short way.

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

- Draining it yourself is not the answer: a can of siphoned petrol on a verge is a danger, and your fuel beyond the tank remains where it is anyway.

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

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

- First, three questions: which fuel got in, the quantity, and has it run? Those replies shape the job, and so the price follows them.

- Clearing it is how the mixture gets taken out of your tank.

- If it ran, the lines are carrying petrol that has moved beyond the tank — so they're rinsed.

- Cleaned, or changed if your car has a serviceable one: your filter is dealt with next.

- Priming comes after fresh diesel is in.

- First start on fresh diesel. Once priming is finished, the motor is started and we make sure that it runs properly.

Our technicians wait until it's running on fresh diesel.

The car goes back to normal use straight away, and long-term damage is very rare when it has been spotted soon.

## After your fuel drain: back on the road around Tannochside

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

- 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 and ring us back.

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

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