I installed CNG in my honda city 2006, very much satisfied with the power pick of vehicle. Surprised to see the average in just Rs 350 of gas it runs more than 160 kms in city on highway it runs around 190 to 200 km.
I am very glad that I converted my car to CNG or I would have never realized that how cost efficient drive my car can be at just 2.25 rs per km
I recommend it.
