from the various customers i have for tyres etc, most get 9-10 km/l on the d4d and 6.5-7.5km/l on the v6.
the hilux raider recieved a mils facelift in october 2007. the following was done.
1. chrome inserts on grille.
2. drivers side one touch automatic window switch.
3. removal of toyota large sticker on tailgate.
dont think another facelift will come anytime soon.
