Brother,
As suggestion, never feed Honda's oil to your Car.
Your car average is good. But yet it can be improved further if you use synthetic oils from imported companies like PPT Performa, Liqui Moly, Volvoline, etc. I never recommend to feed new cars with local oils like shell, total, Caltex, etc.
You will feel the significant improve in your fuel mileage with these imported oils.
Cheers.
