2003 TL Chassis 300,000 - engine ~110,000.

Everything engine related brand spankingly new (aside an O2 sensor - whoops) - Just drove from Adelaide (Bolivar) to Pt Pirie last night (2.5 hour drive, so 250kms?) at mostly 110km/h and I got 8.8L/100km with the 3.5 & 4 speed - so about half a tank on the gauge.

With a 1 ton 12x8 "aerodynamic" box behind it on the way back we got ~12.5L/100km - almost a full tank on the way back (pirie -> bolivar)

Holy shit this thing is not economical at all - maybe I'll get a better result with a new O2 sensor though.
