Ano say niyo po? I really can't seem to get myself straight on how to fully economize fuel. Mas mababang rev? or teka...how about shifting to a higher gear at most.Just like, everytime it reaches 1.5k rev shift to a higher gear advisable ba ito? or mahihirapan lang ang makina? Nalilito ako! I even went to the extent of measuring the distances I'm travelling. :D
