Why Do Fuel Prices Differ Across States?

Petrol and diesel prices are influenced by several factors, including international crude oil prices, the rupee-dollar exchange rate, refining and transportation costs, central duties and state-level taxes. Since VAT and other local levies vary from state to state, retail prices are not uniform across India.

Global crude oil developments also remain important for India, which depends heavily on imported crude. Changes in international supply conditions, geopolitical developments and currency movements can affect the overall cost of crude and petroleum products.

Despite these factors, retail petrol and diesel prices showed no fresh change on August 21. The steady rates come as consumers continue to closely track fuel costs because even small changes can affect household budgets, daily commuting expenses and transportation costs.

Vehicle owners should remember that fuel prices may differ between neighbouring cities within the same state as well. Checking the latest local rate can therefore help motorists stay updated before visiting a fuel station.
