I have this toyota corolla 96 XE

my gas consumption now is 8.5 to 9 km per liter city driving kapag long drive i reach about 14 to 15 km per liter..

I would like to improve my gas consumption in city driving.. masaya na aku if aabot ng 11 km per liter city drive..


any suggestion?.. how to drive?.. parts to change? parts to be checked?

na uubos ang salary ko sa gasolina lng
