something more to share with you guys.. the mileage log that i keep. I have two log books always in the glove box of my car, one to note daily running & the other for maintenance & repairs. Its my practice that on each refill i use to note down the previous mileage reading from tripmeter and the amount of gas thats filled. this not only gives me accurate information about the consumption but also helps me know which filling station provides best pressure. last night i refilled and the trip meter reading was 171.7km which is the highest ever for my car.. running totally on cng without A/c, switching to petrol at night and starting on petrol daily.. keeping in view that the running is in karachi with 5th gear hardly applied, i guess its quite exceptional MashaAllah. in winters mileage on CNG becomes great due to better compression of gas, last year the best i got was 164.4km.
few images of the log that is maintained... the record 171.7km
a page from past... also shows how cheap the gas was 
note that the mileage in the month of June is very low as most of the times airconditioner is operated.
