Series 2 (Neo), auto, hiflow, 15psi, Haltech, shitty rich tune, full 3" exhaust, fmic, pod, coilovers, 18's.
Around town I get ~350km/tank, country driving (did a 1300km round trip over easter), 600km/tank (with many jaunts off the clock).
More economical at 140km/h than 110km/h.
Now that I've made my VCT work, I'm getting about another 50km/tank around town.
