Petrol Diesel Price Today, October 21, 2026: Oil marketing companies have published the latest petrol and diesel rates across India for Wednesday, October 21. Fuel prices are generally updated at 6 AM every day, making it important for motorists to check the prevailing rates before visiting a petrol pump.

Petrol and Diesel Prices Today: What Motorists Should Know

Fuel expenses remain an important part of everyday household spending, especially for people who regularly travel by car, motorcycle or commercial vehicle. Even a minor difference in petrol or diesel prices can affect monthly transportation budgets.

In India, major oil marketing companies, including Indian Oil Corporation (IOCL), Bharat Petroleum Corporation Limited (BPCL) and Hindustan Petroleum Corporation Limited (HPCL), follow a daily fuel price revision system.

Under this mechanism, petrol and diesel prices are generally reviewed every morning at 6 AM. However, daily reviews do not necessarily mean that retail prices change every day.

International crude oil prices, currency exchange rates, taxation policies and distribution expenses are among the factors that influence fuel pricing.

According to the city-wise rates reported for October 21, 2026, petrol prices vary considerably across major Indian cities. Hyderabad and Thiruvananthapuram are among the more expensive locations in the reported list, while Chandigarh has comparatively lower fuel prices.

Why Have Petrol and Diesel Prices Remained Relatively Stable?

Retail fuel prices in India have experienced periods of stability despite fluctuations in global crude oil markets.

The central government reduced excise duties on petrol and diesel in May 2022, and several state governments also adjusted their respective taxes.

Subsequent pricing decisions, including later retail price reductions, have also influenced the rates paid by consumers.

Although international crude oil prices frequently move due to geopolitical developments, production decisions and changes in global demand, these fluctuations are not always immediately reflected in domestic retail prices.

Oil marketing companies consider multiple factors when determining retail rates, and the timing of price revisions can vary.

Consequently, motorists may notice unchanged pump prices even when international oil benchmarks experience significant movements.

Five Major Factors That Influence Petrol and Diesel Prices in India

1. International Crude Oil Prices

Crude oil is the primary raw material used to manufacture petrol and diesel.

India imports a substantial portion of its crude oil requirements, making the domestic fuel market sensitive to global energy prices.

When crude oil becomes more expensive internationally, it can increase the cost of producing and supplying petroleum products.

2. Rupee-Dollar Exchange Rate

International crude oil transactions are commonly denominated in US dollars.

If the Indian rupee weakens against the dollar, importing the same quantity of crude oil can become more expensive in rupee terms.

Conversely, a stronger rupee can help reduce import-related cost pressures, assuming other factors remain unchanged.

3. Central and State Government Taxes

Taxes represent an important component of retail petrol and diesel prices.

The central government imposes applicable excise duties, while state governments levy value-added tax or other relevant charges.

Because state-level tax structures differ, petrol and diesel prices can vary significantly between neighbouring cities and states.

4. Refining and Distribution Expenses

Crude oil must undergo refining before it can be used as petrol or diesel.

The refining process involves operational, energy and infrastructure expenses.

Transportation, storage, distribution and dealer-related costs also contribute to the final price paid by consumers.

5. Fuel Demand and Supply Conditions

Changes in domestic and international fuel demand can influence market conditions.

Economic activity, industrial production, transportation requirements and seasonal consumption patterns can all affect demand.

Supply disruptions or changes in oil production can also influence global petroleum prices.

However, retail fuel prices do not necessarily respond immediately or proportionately to every change in demand or supply.

How to Check Petrol and Diesel Prices Through SMS

Consumers who want to verify the latest fuel rates can use the SMS services provided by major oil marketing companies.

Indian Oil (IOCL): Send an SMS containing RSP followed by the applicable city code to 9224992249.

Bharat Petroleum (BPCL): Send RSP to 9223112222, following the company's applicable SMS service instructions.

Hindustan Petroleum (HPCL): Send HP Price to 9222201122, subject to the company's current service requirements.

SMS formats, city codes and service availability may change. Customers should verify the latest instructions through the official websites or mobile applications of their fuel suppliers.

Alternatively, motorists can check displayed prices at authorised petrol pumps before refuelling.

How Rising Fuel Prices Affect Household Budgets

Petrol and diesel prices influence more than the cost of filling a vehicle's fuel tank.

Higher petrol prices can increase commuting expenses for people travelling regularly to offices, schools and other destinations.

Diesel prices are particularly important for commercial transportation, logistics, agricultural operations and the movement of essential commodities.

When transportation expenses increase substantially, businesses may face higher distribution costs, which can eventually influence the prices of goods and services.

For example, a petrol price increase of ₹2 per litre would add ₹80 to the cost of purchasing 40 litres of petrol.

Similarly, a commercial vehicle consuming 500 litres of diesel in a month would incur an additional ₹1,000 in fuel expenses if diesel prices increased by ₹2 per litre.

These examples demonstrate why consumers and businesses closely monitor fuel prices, even when daily changes appear relatively small.

Petrol Diesel Price Outlook: What to Watch Next

Future petrol and diesel prices will depend on several factors, including global crude oil trends, currency movements, government taxation decisions and pricing policies followed by oil marketing companies.

Motorists should avoid relying on unverified predictions about upcoming fuel price increases or reductions.

Instead, checking official rates before refuelling remains the most reliable way to understand current fuel expenses.

Final takeaway: The petrol and diesel rates reported for October 21, 2026, show substantial differences between Indian cities. Petrol is listed at ₹102.12 per litre in Delhi, ₹111.18 in Mumbai, ₹112.66 in Jaipur and ₹115.69 in Hyderabad. Since prices may differ by location and supplier, vehicle owners should confirm the latest applicable rates before filling their tanks.
