Engine OIL Civic 1.8

[saad_mirza]

I need your valuable suggestions regarding Engine oil for HONDA CIVIC REBORN.
Which oil should I use for better fuel average and Engine performance?

Current oil: Atlantic 10W-40
Oil change after every 4000Km.
Current Avg: within city 10km/L, Highway 12km/L

Should I use a new oil or the current oil is better?
