Petrol in a Diesel Peugeot 308: Already Driven It?

Keeping the motor off is what matters after you have travelled with petrol in a diesel Peugeot 308, which means you should stop once it's safe and turn the motor off. We can still deal with it where you've pulled up, and when it is spotted soon, permanent damage is very rare.

Your Peugeot 308 can remain where it has ended up, as Petrol in Diesel comes out to it, drains its tank there then clears its fuel system of petrol. When we go, it's running again on fresh diesel.

Noticing petrol in a diesel 308

It's often a couple of miles until the signs appear, as with petrol inside your tank a diesel 308 tends to drive as usual to begin with. Motorists usually notice the following if there is petrol or AdBlue inside the fuel tank:

  • power falls away, particularly as you ask the motor to pull
  • the idle turns erratic, or it runs rough
  • more smoke than usual comes from the tailpipe
  • the dash shows warning lamps
  • it cuts out and might not start again

Look at the receipt if any of these started after you filled up, because it will show which fuel was put in.

Wrong fuel in your Peugeot 308 and the result of driving on it

The fuel tank keeps wrong fuel in your Peugeot 308 in one place till it is drawn out by the engine. Once you drive, it goes through the injectors, the filter and your high-pressure pump. Diesel protects the pump and the injectors as it runs through them while petrol dilutes it, so the further the 308 is driven, the more of your system that mix reaches.

That's why it is better to stop the moment you can than to complete the journey. Usually, a drain and a clean are all a vehicle requires when it's stopped early, because what can do harm is travelling far on fuel that is contaminated.

Yours being the 308 HDi 90 rather than another version of the 308 makes no difference.

Fuel drain on a diesel Peugeot 308

We come to wherever you have stopped

You don't need to move the 308 anywhere. You can leave it at the roadside or at home and we come to it, with no restart and no tow to book.

A safe place, clear of the traffic, is the place to wait if you are next to a busy road, with your hazards on.

About how far you went, which 308 it is and where you've pulled up are the things to tell us when you call 0333 366 0103. The version on the badge, like the 308 CC HDi 110, helps as well.

Fuel drain on your Peugeot 308 once you've driven on it

There is one step more to a fuel drain on your Peugeot 308 after it was driven than to one at the forecourt. No petrol should be remaining between the tank and the motor afterwards, which is why the fuel tank is emptied first and your fuel lines are then opened up and rinsed through with the fuel filter. With clean diesel in and your system primed, we start the engine then make sure it runs properly.

AdBlue in a diesel Peugeot 308 after it has been run

Rough running, smoke and warning lights are the normal signs after you have driven on AdBlue in a diesel Peugeot 308, and the car may then stall. Settling to the bottom of the tank, where your fuel pump picks up fuel, AdBlue reaches your fuel line fast, and it doesn't burn or lubricate. Its water drying lets the urea crystallise in your lines and your fuel filter.

AdBlue removal from a diesel Peugeot 308 after it has run

We change the filter if it needs it as part of AdBlue removal from a diesel Peugeot 308 after it has run, once the tank is emptied and the crystals are cleared out of the filter and your fuel lines.

A dedicated AdBlue tank, if your 308 has one, is left alone. The work is about fluid in your diesel tank, and does not mean removing or turning off an AdBlue system.

The cost of a fuel drain on the Peugeot 308 after a drive

The price of a fuel drain on the Peugeot 308 after it's been driven hinges largely on how far it travelled and where it has stopped, and whether it was petrol or AdBlue makes a difference too. We can explain what the job will involve when you ring with those details.

Common questions after driving with petrol in a diesel Peugeot 308

Is the 308 ruined now?

The chance of that is very low. We empty and clean the fuel system wherever you've stopped, and if the vehicle has been stopped early, permanent damage is uncommon.

Should I drive it home first?

Our advice is not to. Contaminated fuel reaches further into the fuel system with every mile, so keep the 308 where it is while we drain it there, with no reason to move the car.

It will not restart after stalling. What now?

Trying again draws more of that mixture through with each attempt. Please leave the car alone. We get it started for you after draining and flushing it, putting fresh diesel in and priming your system.

Which 308 I have: does it matter?

There are 19 diesel versions of the 308, and the badge on the tailgate shows which one you have. Knowing that assists us when you call.

Wrong fuel in my Peugeot 308: does insurance cover it?

Misfuelling cover is included in some insurance policies, so check yours after the vehicle has been sorted out. Whatever it says, we still come out.
