Northenden: Petrol in a Diesel Car? Here Is What Happens
Not for a second, and not for moving it: the engine remains off. Stop there. The next few minutes decide it more than anything else: petrol in a diesel that has not run usually comes down to clearing then rinsing, on the spot. Wherever you happen to be around Northenden, here is the order things go from now.
Petrol in a diesel, motor off — the first minute
In this order, and before anything else:
- Priming the fuel system pulls petrol from your tank towards the components it damages, and switching your ignition on can be all it takes to do that. So the keys come out, and the ignition remains off altogether.
- Topping up with diesel sounds like it dilutes the problem. It does not: nothing comes out, and your tank simply holds more of the same.
- Hazard lights on. If you're anywhere near moving traffic, make your car simple to see before you do anything else.
- Off the pump by hand. At a forecourt, get the attendants to help you roll the car clear of the petrol pump. Don't fire it up to shift it, however short the way.
- The first question you will be asked is which fuel you put in and roughly how much — and the till receipt shows both. Keep it.
If you were still on the move when you realised, stop somewhere sensible instead of pushing on for the services — on the M60, under a mile from Northenden, that means the next junction. Step one follows.
Has it run yet? The fork in every Northenden fuel drain
Everything after this stage rests on one answer.
Not run, not even briefly:
- All the petrol sits in your tank, and only there.
- The work is a simple drain and a flush, usually done where the vehicle stands.
- This, here, is the best position to be in, and the reason stage one counts.
If it has been started, even for a moment:
- The fuel lines and the filter now hold petrol pulled from the tank.
- A bigger run carries it right through to your high-pressure pump and the injectors.
- The farther it went, the bigger the job — the fuel lines, your filter, and now and then more besides.
The reason the line falls there: diesel lubricates your high-pressure pump and your injectors as it passes through them, and petrol does not. Petrol sitting in a tank harms nothing. Once it is pumped, petrol starts wearing whatever moves it.
What to have prepared when you call about petrol in a diesel from Northenden
A technician that circles versus a van that finds you: a little planning is the difference.
- The ideal place to start is a postcode — one beginning M22 4 — for where you have stopped.
- Name the street — Kingsley Road or wherever you have stopped — or the car park.
- What a car park serves is the easiest way to find it, and so say the landmark — like the one at Aldi.
- Tell us what the vehicle is — make, model — and check it is diesel.
- Petrol or AdBlue? Say which. They are separate jobs, and AdBlue has a separate Northenden page.
- How much. Litres from your receipt, or how long the nozzle was in.
- If it has run, how far and how heavily — and whether it has run at all.
- Settle who owns your car before our engineers arrive: some hire and company contracts want the owner to approve this work, and that is faster first.
Then ring 0333 366 0103. If it can wait — the car is at home and going nowhere — does the trick as well.
The wait for a Northenden fuel drain, and what to do in it
During the wait, the damage comes from well-intended help — which is why these count.
- Safety before the vehicle. If it has stopped somewhere dangerous, get yourself clear of the traffic and wait away from it. If it is safe where it stands, wait with it.
- Not to roll it a few yards, not to check it is all right, not for a passer-by's favour: nobody starts it.
- No additives. Two-stroke oil, injector cleaner, anything from your boot — none of it gets the petrol back out.
- Siphoning petrol into a can at the roadside is risky — and it also leaves whatever fuel has already gone beyond your tank. Don't drain the car yourself.
- Leave the ignition off — the windows and the radio included.
When our van arrives: your fuel drain, step by step
- The quote comes after three questions, not before them — what was put in, how much, and if it's run — since those replies set this job.
- That tank is emptied. The contaminated mixture comes out of the tank.
- If it ran, the fuel lines are carrying petrol that has moved beyond that tank — so they are cleaned.
- The filter is seen to. Cleared, or changed where your car has a serviceable one.
- Clean diesel in, and your system primed.
- The start-up. With clean diesel in and the fuel system primed, it is fired up and tested to be sure it runs properly.
Only once it is running on new diesel do we go. It's very unusual for a vehicle noticed early to be left with lasting damage, and normal driving resumes straight away.
Once the fuel drain is done: driving in Northenden again
- Drive normally. There is nothing special to do after it's been started on fresh fuel.
- Watch the first miles. A warning light, smoke, a lumpy idle or a flat spot under your throttle means pull over then ring us back.
- Keep the paperwork. A hire firm, 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.
