How often are petrol and diesel prices updated in India?

Petrol and diesel prices in India are updated daily at 6:00 AM IST. This system is known as dynamic fuel pricing (or daily price revision), which ensures that even minute variations in international crude oil prices and currency exchange rates are reflected in retail prices.

Why do petrol and diesel prices vary from state to state?

Fuel prices vary across states due to local taxes (Value Added Tax or VAT) levied by different state governments. In addition, transportation/freight costs from oil refineries to retail pumps in different regions also contribute to the price differences.

Is GST (Goods and Services Tax) applicable on petrol and diesel?

No, petroleum products (petrol, diesel, crude oil, natural gas, and aviation turbine fuel) are currently excluded from the GST regime. Instead, they are subject to Central Excise Duty and State VAT.

Who determines the daily petrol and diesel prices in India?

State-run Oil Marketing Companies (OMCs) — namely Indian Oil Corporation Limited (IOCL), Bharat Petroleum Corporation Limited (BPCL), and Hindustan Petroleum Corporation Limited (HPCL) — determine the prices daily based on the average international rate of crude oil and foreign exchange rates.
