Mileage

Hmmm.. car, LPG, low mileage, me think, how to improve.

My car (Wagon R Duo) is yielding a mileage of around 11 km per litre of LPG in the city. On the highway depending on the length of the tour yields around 13 to 14.5 km per litre of LPG. Is there any other way of making this car yield a bit more per litre. The price of LPG has been fluctuating since last Oct as me have seen it. Its now back to last Oct levels. Mostly will increase in the near future as all oil prices go up.

Reliance petro..... are u guys listening....pump out all the gas from the KG basin and deliver it at the pumps at lower prices
