Heres some actual fuel consumption for Montero Sport 4x2 2.5 Liter turbo intercooler. Im from Manabo, Abra visiting Manila at least once a month using my new 2009 Montero Sport covering 450km one way of 10km rough road (some gravelled, muddy and the rest pock marked) one river crossing, four section of one way lane bcause the road is under construction in the ilocos region (30-60min idling) and the rest pave road including the nlex and sclex. Last May my Montero still new, i drove at an ave of 120km/hr expressway, 80km/hr McArthur hiway, and 30-50km/hr at the unpaved provincial road. Consumption is 11.28km/liter. Last June covering the same distance and driving faster @130/100/60km/hr my consumption is 10.79km/liter. This month my 900km round trip at a faster pace 140/110/70 km/hr my fuel consumtion is again lower at 9.88km/li. To top all this driving, early this month, I attended the burial of my wife's cousin in Balbalasang, Kalinga, thru the newly opened Abra-Kalinga road. The montero sport climb thru the mountain trail, the worst and roughest road I ever travelled, without a hitch. 195km, 70% is very rough road and my fuel consumption back and forth is 7.02km/li. All this figures are recorded and metered. Hope this will help. Good luck and happy picking!
