Hi guys. i've bought me a swift this month. So i've done over 2,500 KMs so far and the fuel average isn't impressive. Yesterday I had to take a little trip so thought to check the fuel average and had the tank filled at recommended petrol pump. I already had 2-3 Litres in my tank before filling, so I didn't bother going beyong Rs.3,800/=
There was still a few litres capacity but I stopped. Anyway, I filled at 2183 and stopped at 2574 and the result's in the pic below. That's hardly 4-5 litres of petrol left in the pic below. And since I didn't fully filled the tank before trip, subtract a 2-3 litres from then as well, that's around 7 litres of petrol out of a full tank, which is some 44-45 litres. So, I did 391 KMs in almost 38 litres, 300 of which were done on highway and only 91 KMs were done in city. AC was never turned off throughout the trip.
So personally, I'm not impressed with the average given my daily running of over 50 KMs and I don't intend to switch to CNG either. I don't expect over 20 KMPL but at least 12 in city and 15 on highway.
