Time for a report card after 2 months of driving the Jazz. The mileage did not improve very much, sad to say, averaging 13.5 km/l, and this is with rather careful driving and deliberate effort not to rev up the engine too much. I still think this will improve over time, hopefully hitting 14 km/l within the next few months.
Some tips on mileage improvement – use the paddle shift. In the first and second gear, i found it appropriate to shift up to the next gear when the engine hits 2.2k rpm. From first to second gear, apply pressure on the accelerator to maintain 1.8k rpm and above to avoid losing a lot of power.
One thing i found annoying was when going up a long slope, the auto transmission shifts up from third to fourth gear too early, resulting in loss of power before the slope is overcome. Might have to experiment with down shifting the gear.
