Official figures from the toyota dealer is 21 km/litre based on a media road test but figures from other sources varies from 12-14 km/l depending on speed (60-120 km/h) conditions. City driving is estimated to be 10-11 km/litre.
i get between 12.0 to 14.0 km/l from my 3.0litre D4D TOYOTA Hilux Vigo (Manual gear, Thai assembled).
