Default Does mixed fuel age?

Wayne,
Thanks for this very practical advice.

Would you be able to suggest a stabiliser? I have never heard of this
concept but then there are a lot of things I don't know about.

cheers
Peter

It's great to know that yes, definitively, it does age but it would be
really helpful for a cruiser such as myself to know;

1. How long I can keep mixed fuel?

2. What happens when it is aged? - Does it become less useable in any
way such as clogging carburetors etc


If you add stabilizer when fresh, it should be OK for at least 4
months, possibly more if stored in a cool place out of the sun.

As gasoline (petrol) ages it loses octane and tends to form varnish
deposits. Octane loss causes pre detonation and is harmful to
pistons, varnish deposits are harmful to the carburetor.
