Petrol Diesel Price Today, August 13, 2026: Petrol and diesel prices remained unchanged across major Indian cities on Thursday despite renewed pressure in the international crude oil market. Motorists in Delhi, Mumbai, Kolkata, Chennai and several other cities will continue to pay broadly the same rates as the previous day. However, rising geopolitical tensions and higher crude prices could keep the outlook for domestic fuel costs in focus.

Consumers received some relief on Thursday, August 13, as petrol and diesel prices showed no fresh revision in major cities. Even as uncertainty in global energy markets pushes crude oil prices higher, retail fuel rates in India have remained steady for now.

The stability is important for household budgets, particularly for people who commute daily using personal vehicles. Petrol and diesel prices also have a wider impact on transportation, logistics and businesses that depend heavily on road freight.

While there has been no immediate increase at fuel stations, developments in the international crude market could remain important for Indian consumers over the coming days.

Petrol and Diesel Prices Remain Steady on August 13

According to the latest city-wise rates cited in the report, petrol in Delhi is priced at ₹102.12 per litre, while diesel costs ₹95.20 per litre.

Mumbai continues to have substantially higher petrol prices, with the fuel available at ₹111.21 per litre. Diesel in the city stands at ₹97.83 per litre.

In Kolkata, petrol is priced at ₹113.51 per litre, while diesel costs ₹99.82 per litre.

Chennai motorists are paying ₹107.74 per litre for petrol and ₹99.55 per litre for diesel.

Rates differ from one city to another because the final retail price can be affected by factors including state-level taxation and local charges.

Petrol-Diesel Rates in Major Cities on August 13

Here are the fuel prices reported for selected cities:

Among the cities listed above, Bhopal has the highest petrol price at ₹114.54 per litre, followed by Patna and Kolkata.

For diesel, Bhopal is also above the ₹100 mark at ₹100.30 per litre, while Patna stands at ₹100.20 per litre.

Why Are Global Crude Oil Prices Important for India?

International crude oil prices have once again come into focus amid heightened geopolitical uncertainty, including concerns surrounding tensions between the United States and Iran.

Any disruption or perceived threat to crude supplies from the Middle East can influence global oil prices because the region remains crucial to the international energy market.

This is particularly significant for India because the country imports the overwhelming majority of the crude oil it consumes. The report notes that India's crude oil import dependence is above 85%.

When international oil becomes more expensive, the cost of purchasing crude for the Indian market can increase, potentially putting pressure on oil marketing companies.

Will Petrol and Diesel Become More Expensive?

There has been no fresh increase in petrol or diesel prices on August 13, and higher international crude prices do not automatically translate into an immediate increase at Indian fuel stations.

However, a sustained rise in crude oil prices could increase pressure on domestic fuel economics.

If geopolitical tensions continue to escalate or global oil supplies face disruption, crude prices could remain elevated. A prolonged increase would raise India's crude import costs and potentially create conditions for higher domestic fuel prices.

For now, however, motorists in major cities continue to see stable petrol and diesel rates.

Why Fuel Prices Matter Beyond Car and Bike Owners

Changes in petrol and diesel prices do not affect only people who own vehicles.

Diesel is widely used in commercial transportation, including trucks that carry food, consumer products, industrial materials and other goods across the country. Higher fuel expenses can therefore increase operating costs for logistics and transportation businesses.

Public and private transport operators may also face higher costs when fuel becomes more expensive.

If elevated transportation costs persist, businesses may eventually attempt to pass part of that burden on to consumers. This is why movements in fuel prices can have broader implications for household expenses and inflation.

Why Petrol and Diesel Prices Differ Across Cities

Petrol and diesel do not necessarily cost the same throughout India.

The amount consumers ultimately pay at a fuel station can vary depending on the applicable tax structure and other local components. Consequently, neighbouring states—and sometimes nearby cities—can report different retail prices for the same fuel.

This explains why petrol costs ₹102.12 per litre in Delhi but exceeds ₹110 per litre in cities such as Mumbai, Kolkata, Jaipur, Patna and Bhopal according to the rates cited above.

Consumers travelling between states may therefore notice significant differences in fuel prices.

No Immediate Change, but Crude Oil Remains the Key Factor

For motorists, the key takeaway for August 13, 2026, is that petrol and diesel prices remain stable across the major cities covered in the latest rate list.

Delhi petrol stands at ₹102.12 per litre, Mumbai at ₹111.21, Kolkata at ₹113.51 and Chennai at ₹107.74. Diesel prices also remain unchanged in the reported markets.

The bigger factor to watch now is the international crude oil market. If geopolitical tensions ease and crude prices stabilise, pressure on India's fuel market could moderate. On the other hand, a prolonged surge in crude prices could increase concerns about the future direction of petrol and diesel rates.

Disclaimer: Petrol and diesel prices can vary by location and may be revised by oil marketing companies. Consumers should verify the latest rate applicable at their local fuel station before making a purchase.
