Mine AGS gave 21.9 km/l (manually calculated) in last full tank, in Lahore city drive(including 60km on ring road out of about ~700km total). Previous tank full gave avg between 18-19 km/l(of course w/o AC), I think oil change did the trick last time.
I think we had discuss few days back and I shared some factors to consider in below post:
How do you compare these factors?
