I did get 16km/l during one of my trip to KL, that was with old toyo stock tire. Seldom touch 16km/l after changing tire. The 2008 new Latio also fit with the same toyo tire, guess the FC will be better with toyo tyre but I prefer safer wet tire even at the cost of FC. If you mainly drive aroud city and FC is very important to you can try Toyo tire next time.
