Petrol and diesel prices are the costliest in Andhra Pradesh, Telangana, and Kerala. Smaller states and Union Territories like Andaman & Nicobar Islands, Delhi, and those in the North East have the cheapest prices. The differential in local sales tax or VAT rates explains this disparity.

Petrol consumption in India rose by 9.3% and diesel sales increased by 3.1% in January compared to the previous year. Sales of petrol and diesel between April and January have grown by 6.1% and 4.3% respectively. State refiners have gained market share in the private sector. Jet fuel sales rose by 6.2% in January and cooking gas consumption expanded by 6.9%.

Consumption of petrol and diesel rose in September due to increased vehicle sales and expanding economic activity, according to sales data. Private retailers are regaining market share, leading to a decline in diesel sales for state companies. Jet fuel sales showed increased air traffic, and cooking gas consumption also rose. The monsoon months typically see a decline in diesel consumption due to rains affecting demand in the agriculture sector and slowing vehicular movements.
