:thumbsup: :thumbsup: :thumbsup:
Your Latio is really one in a million. :thumbsup: :thumbsup: :thumbsup:
Even when I just drive alone, mostly highway driving, never rev above 2500rpm, travel at 80km/h, air con thermostat set at 26 degrees, best I got was 14km/l.

hi bro, yr car still very new and sb able to hv better FC rite? Or u must be cheongter then? Mine > 3yrs now with best achievement of 13.5+KM/l in local and ~17+km/l 100% on malaysia NSHW. Do follow some tips given by some fellow lations for better FC. :smile:

When you floor the pedal to hit 5K+ rpm, the engine has to go into open-loop mode momentarily. That is not really a fuel saving technique. While throttle losses are reduced, excess fuel is used to cool the engine to avoid detonation (engine burns rich when > 3/4 throttle). Also high rpms increase losses due to friction.
It is generally agreed that shifting up at low rpm in MT equipped cars is the most efficient way to accelerate. This does not mean that you need to use light throttle. Opening the throttle while keeping engine RPM low minimises throttle loss. I am not sure if 5k+ rpm on an AT has the same effect. You might be able to get 18~19km/L.
Anyway, the ECU & TCM will ensure that the engine is never "dragged".

No matter how hard I try, I can never achieve 18 to 19km/l when I drag my engine beyond 5,000rpm. Is there a special technique to achieve this?
I get 10+km/l at best if I drag the engine beyond 5,000rpm.
When I drag past 5,000rpm, by 2nd gear, I am almost at 100km/h.
