Llanion: Petrol in a Diesel Car? Here Is What Happens
Not for a second, and not for moving it: the motor remains off. Pause there. Petrol in a diesel that hasn't been run is typically a simple drain plus a flush, done right where the car stands, and what happens in the next few minutes settles that more than anything else. Below is the order from here, wherever in Llanion you happen to be.
Petrol in a diesel, motor off — the first minute
First, the following — following this sequence.
- Pull the keys out. Even the ignition on its own can prime the system, drawing petrol out of your tank to exactly the components it damages, and so keep the vehicle off entirely.
- A bigger tank of the same mixture is all topping up gives you, because it removes nothing. So no more diesel.
- Being seen comes first near moving traffic: switch the hazards on, and only then deal with everything else.
- Off the petrol pump by hand. On a forecourt, ask the staff to help you roll the vehicle away from the pump. Don't start the car to move it, however short the way.
- The first thing we will ask is which fuel you put in and roughly how much — and your receipt says both. Hold on to it.
Still on the move when you noticed? Come off the M4 at the next exit if that's where you are, under 50 miles from Llanion, and pull over somewhere sensible instead of pressing on to the services. Then start at step one.
Llanion fuel drain: has your motor run yet, or not?
What happens next rests on one answer, and only one.
If it has not once been started:
- All the petrol remains inside the tank, and just there.
- Normally it's emptied and purged just where your car is.
- Being here is as good as it gets — which is the entire point of stage one.
If the engine has been run, even for a moment:
- Out of that tank, through your filter, into your lines: that is how far that petrol has got.
- Your high-pressure pump and your injectors get it on a longer run.
- The further it went, the bigger the job — the lines, the fuel filter, and now and then more besides.
The line falls there since diesel lubricates the high-pressure fuel pump and the injectors on its way through them — and petrol doesn't. A tank of petrol, left alone, damages nothing. Petrol being pumped is wearing the components that shift the vehicle.
What to have ready when you call about petrol in a diesel from Llanion
Get ready a little, and the van finds you instead of circling.
- Where you are. A postcode beginning SA72 6 is the best place to start.
- The street or the car park. A road name helps — London Road, or wherever you have pulled up.
- Or the nearest landmark. A car park is easier to find by what it serves, like the one at Tesco.
- That it is a diesel, along with the make and model of the car.
- Tell us which went in — petrol or AdBlue — since AdBlue is a different job, with a page of its own for Llanion.
- Roughly how much — in litres from your receipt, or by how long the nozzle was in.
- The miles it covered, and how hard, if it has run at all.
- Settle who owns the car before our engineers arrive: some hire and company agreements want the owner to authorise this work, and that is faster first.
Ring 0333 366 0103 next. Writing to works as well if it can wait, with your car parked at home, going nowhere.
While you wait for a fuel drain around Llanion
Hold to these: kindly meant help does the damage during the wait.
- Where your car has stopped decides where you wait. Somewhere exposed: away from it, away from the traffic. Sensible: with it. Either way, safety before your car.
- Not to roll it a few yards, not to check it is all right, not for a passer-by's kindness: nobody starts it.
- Something from the boot, oil meant for two-strokes or injector cleaner: no additive removes that petrol.
- No DIY draining. Siphoning petrol into a can by the kerbside is risky, and it leaves the fuel that has already gone beyond the tank.
- Even the radio or the windows are not worth turning your ignition on for.
Step by step: the fuel drain when the van gets there
- Three questions. What was put in, how much, and whether it has run. The answers decide this job, which is why our quote comes after them and not before.
- Out of your tank comes the polluted mix: your tank is drained.
- Rinsing the fuel lines follows, because a vehicle that ran has petrol past the tank, inside the fuel lines themselves.
- The fuel filter is dealt with. Cleared, or changed where your car has a serviceable one.
- The system is primed on clean diesel.
- Starting the car. After your system is bled with new diesel, our engineers fire it up and confirm it runs properly.
Until it runs on clean diesel, we stay with it. The vehicle returns to normal use straight away, and long-term damage is very rare when it has been caught quickly.
Back on the road around Llanion after the fuel drain
- Drive normally. There's nothing unusual to do after it's been started on clean fuel.
- Give the first miles your attention. Smoke showing, a warning light coming on, the idle going lumpy or your throttle hesitating: pull over and call us back.
- Your paperwork answers the question a rental company, fleet manager or insurer may ask: what work was carried out. File it.
- Read the label on the petrol pump next time, not the colour of the handle.
