Aged fuel message

BillyJay · Sep 30th, 2021, 14:57

I got this when I had just under half a tankful so I filled up and still get the message. The tank is now about a third full. How low should it get before I top it up again? I should say that I do very little mileage.

If it is going to be stood for long periods or with little use and small trips I would not fill the tank, just add small amounts as you need it. (I did not know they gave this warning)

You're actually in a bit of a catch 22. On the one hand you're being warned that your fuel is 'aged' (I didn't know it told you this either. I assume it times how long since the gauge went up). On the other hand if you don't keep the tank fairly well topped up condensation build up can result in increased water content in the fuel which in turn encourages diesel bug. Have you noticed any drop off in performance or difficulty starting? I'd be interested in knowing why Volvo incorporated the warning into the software.

Is it a T8?

My wife has a plug in hybrid, (Mitsubishi) during the first lockdown she drove so few miles (and all on electric) that her car generated a similar message and refused to tun on battery only until the petrol had been burned off.

It is part of the system Mitsubishi employ to prevent stale fuel damaging the engine. (She then stupidly put another full tank of petrol in and had to go through the same problem a few months later)

I can see that being a problem with a plug in hybrid car, especially if mainly only doing short trips on battery only. In that case It would make sense to just keep a small amount of petrol in the tank and top it up if planning a longer journey.

At what point is petrol considered stale? I always keep my tank at about 3/4 full and now I'm working from home most of the time, I can go a few weeks without needing to drive.

And if I use 1/4 and then top back up, does it "renew" the fuel as it's been mixed with fresh, or does it need to have the tank pretty much emptied and start again?

I have never seen any water in any volvo fuel tank I have looked into, over the years its probably about 3 or 4 a year.

This is a strange one for me Clan.

Two things:-

1) The Aged Fuel message appeared as I was sitting on the forecourt after filling up.
2) Six months ago my Volvo dealer didn't change the fuel filter properly and it cut out while driving the morning after a major service. They hadn't primed/purged the system. Fortunately the electric bit got me to the garage. But, this was a one off and I've done 7000m since.

I don't get why it says 'Aged Fuel - run diesel engine to burn off fuel' (before I can use electric again)...

Is your car an old style V60? I don’t think there are any SPA diesel hybrids so if it is you might find someone in the other V60 forum who has a similar problem?

It calculates the fuel state by plotting time against volume of fuel used, as a hybrid could get by with very little refuelling and the fuel could get stale.
