Brother I have a M/T EXi running on Rs. 5,500 LiquiMoly oil and 6,000 K&N air filter and it never gave above 9km/l even at 2,000 RPM and you have to witness Alto and Cultus leaving behind u in dust.
haha yea happens many times, i am driving slow n mehran alto leave me behind
9km is pretty less though for 2k rpm, i did managed 10kmpl with 2k rpm once but it was a lot of patience, could never try that again
though now once i reach at 70-80 then i maintain rpm of 2k
