Hi! I have a Honda City type Z. It has always been my habit to compute for the fuel consumption every time I fill up with gas. My average is 11-13/14km/L mixed city/highway driving. But earlier when I filled up with gas, I was surprised with my consumption, 9.6km/L!

Wala namang nagbago sa driving style and ruta ko.. Alaga naman sa change oil etc every 5Tkm. BTW, it's a 10yr old car.

Ano kayang deprensya? Thank you for your inputs.
