A similar observation for me, I am 27 years and I remember we were paying Rs 15.50 (aprrox.)per liter at the begining of nineties. Anyway as we know the resources are limited so the prices will continue to increase but the govt. can have some control by adjusting the taxation policies. But we are likely to switch over to other sourses of energy very soon like electri bikes or hydrogen fuel which is the demand of time.
