Petrol and diesel prices across major Indian cities remained unchanged on Monday, September 21, 2026. The latest rates come despite international crude oil prices staying above $100 per barrel amid renewed geopolitical tensions.
Government-owned oil marketing companies revise petrol and diesel prices every day at 6 am. The retail rates are influenced by several factors, including global crude oil prices, currency exchange movements, taxes and other costs.
For motorists, there was no change in fuel prices in the latest daily revision. However, petrol and diesel rates continue to vary from one city to another because state taxes and other local charges differ across the country.
Petrol and Diesel Prices Today
On September 21, petrol and diesel prices remained steady across the major cities covered in the latest revision. Consumers therefore saw no change in the rates at fuel stations compared with the previous day.
While domestic prices were unchanged, international crude oil remained expensive. Brent crude was trading at around $105 per barrel, while West Texas Intermediate (WTI) was close to $101 per barrel.
The difference between international crude prices and domestic fuel rates can occur because retail prices also include taxes, dealer commissions and other components.
Why Fuel Prices Differ Across Cities
The price paid by consumers at petrol pumps is not based solely on the cost of crude oil. Central and state government taxes, dealer commissions and other applicable charges form part of the final retail price.
State-level taxation is one of the major reasons petrol and diesel can have different prices in different parts of India, even when the underlying crude oil price is the same.
Check Fuel Rates Before Refuelling
Although petrol and diesel prices remained unchanged on September 21, fuel rates are reviewed daily. Changes in international crude prices, foreign exchange rates, taxes and other factors can influence future revisions.
Consumers should check the latest applicable petrol and diesel prices before refuelling, particularly when planning longer journeys or monitoring their monthly fuel expenses.
