Dorcan: Petrol in a Diesel Car? Here Is What Happens
Stop. Engine off. Leave it that way — no moment on, no moving it anywhere. Petrol in a diesel that hasn't been run is generally a drain and a flush, done where the car sits, and what you do in the next few minutes settles that more than anything else. From here on, in order, wherever you are in Dorcan:
Petrol in a diesel? What to do in minute one
First, these — following this sequence.
- The ignition off, keys out. Turned on, the ignition can prime the system — and priming is what moves petrol out of your tank towards the parts it harms.
- No diesel on top. More fuel in takes away none of the petrol — it only leaves you with extra of the same mixture.
- Being seen comes first near moving traffic: put your hazards on, and only then deal with anything else.
- However short the distance, starting it to move it is the mistake. At a forecourt, roll the car clear of the pump by hand instead, then ask the staff to help.
- Keep your receipt. It shows which fuel went in plus roughly how much, which is the first thing we will ask.
If you were still driving when you noticed, stop somewhere safe instead of pushing on for the services — on the M4, under 3 miles from Dorcan, that means the next exit. Stage one comes next.
Has it run yet? The fork in every Dorcan fuel drain
Everything after this point rests on one answer.
Motor not run at all?
- No place but your tank: that's where that petrol still is.
- The work is a drain and a flush, usually done where the car stands.
- This is the best spot to be in, and the reason stage one counts.
Run at all, even for a second:
- From that tank, past the filter, into the fuel lines: that's how far that petrol has got.
- On a longer run it has got to your high-pressure pump and your injectors.
- The job expands with the miles — lines rinsed, filter seen to, sometimes more.
Diesel keeps the high-pressure fuel pump and your injectors oiled as it goes through them. Petrol gives them nothing, and that is why the line is drawn there. Nothing is harmed by petrol that is just resting in a tank. Once it's pumped, petrol begins grinding whatever moves it.
Before you call about petrol in a diesel in Dorcan: what our technicians need
A little preparation is the difference between a van that finds you and a technician that circles.
- SN3 5 plus the remainder of the postcode is the best way to start telling us where you are.
- The street or the car park. A road name is a help — Edison Road, or wherever you have pulled up.
- Car parks are found most easily by what they serve: say the one at Morrisons, and it is simple.
- That it is a diesel, plus the make and model of the vehicle.
- Say which got in — petrol or AdBlue — since AdBlue is a separate job, with a page of its own for Dorcan.
- How much. Litres from your receipt, or how long the nozzle was in the filler.
- Has it run? If so, say how far it went, and how it was driven.
- Hire or company car? Some agreements want the owner's go-ahead for this work, and sorting it before we get there is faster than afterwards.
Next, 0333 366 0103. Not time-critical, your car left at home with nowhere to be? Then works as well.
Waiting for a fuel drain around Dorcan: what to do
Help, however well meant, is what does the damage while you wait. So stick to these.
- Your safety comes before the car. Somewhere unsafe? Get clear of the traffic then wait away from it. Safe where it is? Wait with it.
- No one — however helpful — starts it, whether to see if it runs or to move your car a short way.
- Additives stay in the boot. Injector cleaner and two-stroke oil draw none of that petrol out again.
- Clearing it yourself is out: a can of siphoned petrol on a verge is a danger, and the fuel beyond that tank remains where it is anyway.
- Leave the ignition off — the windows and the radio too.
When the van arrives: your fuel drain, step by step
- Fuel, amount, whether it has run: the replies set the job, and that's why you get a quote after them rather than before.
- Clearing it is how the blend gets taken out of the tank.
- The lines are purged. If it ran, that petrol has shifted beyond the tank, and the lines are carrying it.
- Then the fuel filter: swapped where there's a usable one, cleared where there is not.
- Fresh diesel in, and the fuel system primed.
- First start on new diesel. Once bleeding is complete, the engine is started and our technicians confirm that it runs smoothly.
Till it runs on clean diesel, we remain with it. When it has been caught quickly, long-term damage is very unusual, and your car goes back to normal driving at once.
Back on the road around Dorcan after your fuel drain
- Once it's been started on clean fuel, there is nothing special to do: drive normally.
- Give the first miles your attention. Smoke appearing, a warning light coming on, your idle going lumpy or the throttle stumbling: pull over then call us back.
- An insurer, a fleet manager or a hire firm may ask what was done, and so keep the documents.
- Next time, read the petrol pump. The label, not the colour of the handle.
