I am driving a Mazda 3 2.0 and the fuel consumption is not super fantastic.
Lately I am trying to upshift via the paddle when the rpm is slightly above 2 k. To my understanding, less rev = less fuel consumption. So I am usually at gear 5 in a very short distance from a complete stop position, and I do notice some improvement in FC though I can't be sure if it's because of the change in driving habit.
Will this damage my car in the long run if I do this frequently? Or is it better to leave it at Auto and go light on the acceleration paddle?
Thanks in advance for the advice!

yes u can save fuel when upshift early.....
but if too early then u tends to dragging your engine..especially during high load (slight uphill/full people onboard) and only will make the FC worse...
then u can try experimenting between those manual upshift or light throttle auto and compare them over the same route everyday for a week..and u should get the answer....(there is no specific answer since driving styles vary for any person)

RX maybe can. Pajero cannot, coz no effect on the pick up. Only effecting the FC.

for RX u dont even notice when its redline..
that was true until the low fuel warning sign starts to blink
rallychamp is correct, the best time to upshift is when the engine is running at optimum, not necessary below 2Krpm coz diff engines and gear ratios characteristics set up
