traditional A/Ts give horrible economy in the city.

from i10s to vioses to mazda2s, pag A/T, matakaw talaga compared sa manual.

the weight makes a huge difference, if I remember, parang 1,200 kg lang ata ang altis, ang mazda 3 ata 1,350-1,400 kg. the car has to rev harder and use more fuel for the heavier car

regarding "mali" ang binibigay na fuel: madumi na ang oxygen sensor mo pag ganun. the stock ECU already mixes an optimal amount of fuel with the air - not too rich, not too lean... it's programmed for efficiency, not power.
