G'day Rainsey,
That's gold mate! Agree with ET though, amazing L's used in start/stop city conditions!
I do need maths lessons;
(all 80L maintanks I believe?)
Our stock GU 3.0L made 600-650kms
Our GU 4.2TD with 3" makes around 550-600kms
My 6.5NA makes around 450 to max 550kms.
I'm sure it's the hilly highways and air lacking.
Please do keep us posted, we're all in this together, great song :-)
