Petrol Diesel Price Today, August 20, 2026: Fuel prices remained largely unchanged across major Indian cities on August 20, with motorists continuing to pay more than ₹100 per litre for petrol in several metropolitan areas. Delhi, Mumbai, Bengaluru, Hyderabad and Kolkata are among the cities where petrol continues to stay above the ₹100 mark.

Fuel rates have remained stable since May 25, when state-run oil marketing companies revised petrol and diesel prices. Since then, consumers in most major cities have not seen another broad change in pump prices.

The stability in domestic rates comes even as international crude oil markets continue to react to geopolitical developments and expectations around global shipping routes. Changes in international oil prices do not always translate immediately into retail price revisions in India, as several other components influence what consumers finally pay at fuel stations.

Here is a look at the latest petrol and diesel prices in major cities on August 20, 2026.

Petrol and Diesel Prices in Major Cities

The figures show a considerable difference in fuel prices from one city to another. Delhi residents are paying ₹102.12 per litre for petrol and ₹95.20 per litre for diesel. Mumbai continues to have a significantly higher petrol rate at ₹111.21 per litre, while diesel is priced at ₹97.83 per litre.

In Chennai, petrol costs ₹107.77 per litre and diesel ₹99.55 per litre. Bengaluru motorists are paying ₹110.93 for a litre of petrol and ₹98.80 for diesel.

Patna remains among the costlier cities in the list, with petrol priced at ₹113.37 per litre and diesel at ₹99.36.

Petrol Remains Above ₹100 in Most Major Cities

Petrol continues to trade above ₹100 per litre across most of the large cities included in the latest price list.

In Delhi, the rate stands at ₹102.12 per litre, while Gurugram is slightly higher at ₹102.97. Bengaluru and Mumbai remain well above ₹110 per litre.

For consumers who use private cars or two-wheelers every day, these rates can have a noticeable impact on monthly travel expenditure. Even a small difference of ₹1 or ₹2 per litre can become significant for commuters who regularly cover long distances.

Diesel Prices Also Vary Across Cities

Diesel remains below ₹100 per litre in Delhi, Mumbai, Chennai, Gurugram, Bengaluru and Patna according to the listed rates. Bhubaneswar is an exception, where diesel is priced at ₹100.56 per litre.

Diesel prices are particularly important for the broader economy because the fuel is widely used by trucks, buses, commercial vehicles and parts of the agricultural sector.

Higher diesel costs can increase transportation and logistics expenses, which may eventually influence the cost of moving food, consumer goods and industrial products across the country.

Why Do Petrol and Diesel Rates Differ From City to City?

Fuel prices are not uniform across India because the final retail price includes several components.

One of the biggest factors is taxation. Central duties and state-level taxes make up a substantial share of the pump price. Since state taxes vary, consumers can end up paying different rates even in cities located relatively close to each other.

Dealer commissions, transportation costs and local pricing components can also contribute to differences.

International Crude Oil Prices Still Matter

India imports a large share of the crude oil it consumes. As a result, global crude prices remain an important factor in the domestic fuel market.

Any sharp increase in international crude prices can raise the cost of importing oil. Conversely, a decline in crude prices can reduce the pressure on oil marketing companies.

However, domestic petrol and diesel rates are influenced by several factors beyond crude oil alone, meaning pump prices may remain unchanged even when international oil markets move sharply.

Rupee-Dollar Movement Can Affect Fuel Costs

Crude oil purchases in the international market are generally settled in US dollars. Therefore, the exchange rate between the rupee and the dollar can affect India's oil import bill.

If the rupee weakens against the dollar, importing crude becomes more expensive in rupee terms. A stronger domestic currency can help reduce part of this pressure.

Changes in the currency market are therefore closely watched alongside international crude oil prices.

Why Fuel Prices Matter to Consumers

Petrol and diesel prices have an impact that extends beyond vehicle owners. Fuel is a key input for transport, logistics and commercial activity, so changes in rates can influence the cost of moving goods from one location to another.

For households, petrol affects the cost of daily commuting. For businesses, diesel expenses can have a direct impact on transportation budgets and delivery costs.

This is why consumers and businesses closely track daily fuel-price updates, even during periods when rates remain unchanged.

Check the Latest Rate Before Refuelling

Petrol and diesel prices on August 20, 2026 continue to show significant differences across major cities. Delhi has petrol at ₹102.12 per litre, while Mumbai and Bengaluru remain above ₹110. Patna is even higher at ₹113.37 per litre.

Consumers planning to refuel should check the latest rate applicable in their city before visiting a petrol pump, particularly because taxes and local pricing components can create noticeable differences from one location to another.
