@ clark's son-
yes i have 2003 model car,last May 26th&27 i went to anuradaha pura(4 passengers),
from ja-ela i fill up the tank full&reset the clock to "0"when i went to anuradapura,clock shows me 225 kms&again i fill up the tank full,its cost 0nly10.6 liters,(without A/C,low RPM,low traffic,my average speed was 60-75kmph)
when im returned back i used dambulla road to ja-ela,(with A/C,there was bit traffic too)(220km)it did 16-17km pl,
im useing octane 95 petrol
im also agree with u bro.i cant belive that it it 22kmpl,hw ever it did on my last trip
