I tried to calculate the consumption on my trip to Murree this sunday.
As I never believe the average shown on the meter, hence i used tank to tank method. Got it filled from fuel station near my home.
Made a trip of 313 kms, and on way back again refilled from the same station for Rs 1330.
So 1330/64.5=20.6 litres.
Hence 313km/20.6L = 15.2 KMPL. AC was on 80 percent of the time (turned it off for some 30-40 kms in Murree)
We were 3 passengers. RPM was kept under 3.5K the whole way, except on motorway i pushed it to 150kmh (4-4.5K RPM)
Now I am really really satisfied with the overall performance of the car and i hope it will maintain the same average, if not improves....!!
