1) Shell RON 97 (daily damansara-sunway) only around 220++km only...i drive 60-100kmh only....why so less?
2) Shell RON 97 (long distance) full tank, i run 80-100 and can drive untill 260km+ only...what happen to my car? i feel like my car drinking water, not petrol!
anyone know how to make it save petrol? if not, every 4-5 days need to pump petrol again....is this ECU need to tune or to set?
