Blackthorn: Petrol in a Diesel Car? Here Is What Happens
Not for a second, and not to move it: your engine remains off. Stop there. The next few minutes determine it more than anything else: petrol in a diesel still unrun generally amounts to emptying and flushing, on the spot. Here is the order of things from here, wherever you're in Blackthorn.
Motor off: minute one with petrol in a diesel
Work through these in sequence, before you do anything else.
- Priming the system pulls petrol from the tank toward the parts it damages, and switching the ignition on can be all it takes to do that. So the keys come out, and the ignition remains off altogether.
- A bigger tank of the same mixture is all topping up leaves you, because it takes out nothing. So no more diesel.
- Hazard lights on. If you're at all close to moving traffic, make the vehicle easy to see before you do anything else.
- However short the distance, starting it to shift it is the mistake. On a forecourt, push it away from the pump by hand instead, and ask the staff to lend a hand.
- Hold on to the receipt. It says which fuel went in and about how much, which is the first thing we'll ask.
If you were still driving when you noticed, pull over somewhere safe instead of pushing on for the services — on the M1, under 10 miles from Blackthorn, that means the next exit. Stage one comes next.
Has it run yet? The fork in each Blackthorn fuel drain
What comes after this turns on one answer, and only one.
If it has never been started:
- Just the tank has petrol in it so far.
- Where your car sits is usually where this work happens: a drain, then a flush.
- No position is better, and it is why the first stage matters so much.
Run at all, even for a second:
- Some petrol has left your tank by now, gone through your filter, and reached your lines.
- On a bigger run it has reached the high-pressure pump as well as your injectors.
- The further it went, the larger the job — the fuel lines, your filter, and sometimes more besides.
The line falls there because diesel protects your high-pressure pump and the injectors on its way through them — and petrol does not. In your tank, left alone, petrol harms nothing. As soon as it is pumped, petrol starts grinding whatever moves it.
Calling about petrol in a diesel from Blackthorn: what to have prepared
Get ready a little, and the van finds you instead of circling.
- The ideal place to start is a postcode — one beginning NN3 8 — for where you have stopped.
- Give the road — Blackthorn Road or wherever you have pulled up — or the car park.
- Name a car park by what it serves — the one at Costcutter, for example — and it's far quicker to find.
- The car. Make, model, plus that it's a diesel.
- Petrol or AdBlue? Tell us which. They are separate jobs, and AdBlue has its own Blackthorn page.
- How much. Litres from the receipt, or how long the nozzle was in.
- Has it run? If so, tell us how far it got, and how it was driven.
- Settle who owns the vehicle ahead of when our engineers turn up: some hire and company contracts want the owner to approve the work, and that is quicker beforehand.
Phone 0333 366 0103 next. Writing to is fine too if it can wait, with the vehicle left at home, going nowhere.
Whilst you wait for a fuel drain in Blackthorn
Help, however well meant, is what does the damage whilst you wait. So stick to these.
- Stay with the vehicle if it's safe where it is — but if it has stopped somewhere exposed, you come first: away from the traffic, waiting apart from it.
- Not to roll it a few yards, not to check it is all right, not as a passer-by's kindness: no one starts it.
- None of that takes that petrol back out — not two-stroke oil, not injector cleaner, not something from the boot. So no additives.
- A home-made drain leaves the fuel already gone beyond your tank, and siphoning petrol by the road is risky too.
- Ignition remains off. Even for your radio or the windows.
The fuel drain, step by step, once the van gets there
- Fuel, volume, whether it has run: those answers decide this job, and that's why you get a quote after them rather than before.
- Out of that tank comes the contaminated blend: that tank is drained.
- If it ran, the fuel lines are holding petrol that has moved beyond that tank — so they're flushed.
- Where the car has a workable filter, it's replaced; if not, cleared.
- Priming follows once fresh diesel is in.
- The first start on clean diesel. Once priming is finished, the engine is started and our engineers make sure that it runs smoothly.
Only once it's running on clean diesel do we go. If it has been noticed early, lasting damage is very uncommon, and the vehicle returns to normal driving at once.
Once the fuel drain is done: driving around Blackthorn a second time
- Nothing special is needed after a start with clean diesel — normal driving will do.
- Pull over and call us back if anything looks wrong early on — a light on your dash, smoke from your exhaust, an idle that runs rough, or a throttle with a dead spot.
- Your paperwork covers the query a rental company, fleet manager or insurer may ask: what work was carried out. Keep it.
- The handle's colour isn't the guide to go by next time — the label on the pump is.
