if say 7km/liter ang M/T tapos 5km/liter ang AT. let's say at 65 liter full tank 65x7 for M/T = 455km vs. 65x5 = 325km ang nacover mo subtract the two (455-325km) = 130km difference between M/T and A/T or around 26 liters pa sana na-save mo. 26 liters x P40 = P1,040 kada full tank savings.
mag AT ka na lang. sarap mag-drive using A/T kung extra 1k lang gastos mo vs. M/T. that's the price of convenience and relaxed driving.
we got a 2.0 M/T and we're getting 13KM/L on highway and an average of 10KM city driving.. Pag sobrang traffic around 8.5KM/L. This is using the on board computer.. I still have to try the old way of measuring fuel consumption.
If you're asking on what to get.. If you're driving in Manila everyday, I suggest the automatic.. Nakakainis ang traffic. But if you are driving in the province. Sarap ng manual and it will save you a lot of fuel.
