rule of thumb for FC :
[RM10 for 40km for 200% jam]
[RM10 for 50km for 100% jam]
[RM10 for 60km for 50% jam]
[RM10 for 70km for 0% jam / highway]
i can conclude only issue is also only about uphill, especially GENTING.
if 1 adult passenger compared with viva or axia, ALZA still loose behind
the new batch Axia genting uphill the power really impressive, can maintain 60 to 80kmh.
as a summary of my personal experience for genting uphill based on standard engine no MOD whatsoever:
Perodua Alza : 20 to 40kmh peak power
Perodua Viva : 40 to 60kmh peak power
Perodua Myvi : 50 to 70kmh peak power
Perodua Axia : 60 to 80kmh peak power
no joke.
i drove viva before go genting, cornering lose but pick up gear 3 rev 4k rpm the car still can go between 40 to 60kmh.
just service my Alza today @ 7th free service / 50k km
although it's free, but the engine oil price went up from rm86 to rm91 already
and oil filter price reduce from rm12.95 to rm12.20
just notice my stock brake pad remain 30%, so lucky i bought last year stand by at my car already, so just change it on the spot.
* do bear in mind, 2013 and older using another model ( which im not sure which model )
* 2013 and newer include the NEW ALZA using this model as attached ( my old 2013 alza is same model with NEW ALZA )





Impressive Viva can win Alza with 1.0cc on Genting..
Hopefully this new 2015 Alza will getting better for uphill.. Btw, it dont really matter to me cause seldom I going Genting..
Just able to cruise normally at 140km/h will be good for me as I will travel alot outstation..
