I also pay 1/6 the cost of casloline and 1/5 the cost of diesel for the cng.
My commute is only 50 km/ day .
If I were to get a vw polo which consumes 3.6L/100 km with traffic that comes to 5l/100km where I live.
So 2.5 liters of diesel of which i can get 0.18 liters almost free. The relative savings are not insignificant.
