How did you get 11.2 avg on a freeway trip to Canberra?
driving in 3rd? lol


You dont have to worry about filling up until the DTE is --- which happens with less than 40km on board.

Once its on that, then you can put in at least 60L.

What reserve tank ? its just a count down from full tank ? And this varies depending on how many K's the gauge reads after filling up

Dry filling 58L means you didn't get all the fuel out. The tune will therefore be off... :oops:

Austin, you need to wait until your needle is well below the last E notch. And then it will probably drive another 20-30kms.

I recently drove from Gosford to Canberra on just under 3/4 tank of e85. Got me to and around (20kms) canberra with plenty of idling and could only get 62L in, the next morning.

It's crazy how hard it is to run the tank dry! :D

I've managed it with the Outback. Not on the Liberty though, I know the dangers of that leaning out... :)

The only thing deterring me from e85 is accessibility. Say I go to the farm, not gonna have e85 up there :(

Also united has removed their 100octane in Canberra for some reason so back to 98 it is

Yeah, United seem to have pulled P100 entirely.
