Petrol Diesel Price Today, August 17: Planning a road trip, heading to work or simply need to refuel your vehicle? Checking the latest petrol and diesel prices before visiting a fuel station can help you estimate your travel expenses. Fuel prices can differ considerably from one city to another because of state-level taxes, local levies and other factors.

On August 17, 2026, petrol and diesel prices in several major Indian cities remained broadly stable, with no major revision reported in cities such as Delhi, Mumbai, Kolkata and Chennai.

While domestic retail rates have remained steady, international crude oil prices have recently shown an upward trend. Here is a look at the latest petrol and diesel prices across major cities and why fuel rates can vary depending on where you live.

Petrol and Diesel Prices in Delhi Today

Consumers in the national capital continue to see relatively lower fuel prices compared with several other major metropolitan cities.

On August 17, petrol in Delhi is priced at ₹102.12 per litre, while diesel is available at ₹95.20 per litre.

There has been no major movement in the city's petrol and diesel rates over the past few days, according to the available price data.

For motorists who travel long distances regularly, even small changes in the per-litre price can have an impact on monthly fuel expenditure. Checking current rates can therefore be useful when planning a long journey or managing transportation costs.

Mumbai Petrol and Diesel Rates on August 17

Fuel remains more expensive in Mumbai compared with Delhi.

The latest available rates show petrol in Mumbai at ₹111.21 per litre, while diesel is priced at ₹97.83 per litre.

Differences in taxation and other local components are among the reasons retail fuel prices vary across states and cities. As a result, consumers may notice a significant difference in the amount they pay for the same quantity of fuel depending on their location.

Kolkata Fuel Prices Remain Stable

Petrol and diesel prices are also holding steady in Kolkata.

Petrol is currently priced at ₹113.51 per litre, while diesel costs ₹99.82 per litre.

At these rates, Kolkata has one of the higher petrol prices among the four major metropolitan cities listed here.

Consumers should remember that petrol pump rates can be revised, so it is advisable to check the latest price before refuelling.

Petrol and Diesel Prices in Chennai

In Chennai, petrol is being sold at ₹107.76 per litre, while diesel stands at ₹99.55 per litre.

The available figures indicate no major change in the city's fuel prices on August 17.

This places Chennai's petrol rate above Delhi but below the quoted prices in Mumbai and Kolkata.

Petrol and Diesel Prices in Major Indian Cities

Here is a quick comparison of the latest available petrol and diesel rates across eight major cities:

Among the cities listed above, Hyderabad has the highest quoted petrol price at ₹115.69 per litre, while Lucknow has the lowest at ₹101.89 per litre.

For diesel, Hyderabad is also the most expensive among these cities at ₹103.82 per litre, while Delhi has the lowest quoted price at ₹95.20 per litre.

Why Do Petrol and Diesel Prices Differ Across Cities?

Consumers often wonder why petrol or diesel can cost significantly more in one city than another.

Retail fuel prices are influenced by several components. These can include the underlying fuel price, central and state-level taxes, dealer commissions, transportation costs and other applicable charges.

State-specific taxation is particularly important in explaining why consumers may pay different prices in Delhi, Mumbai, Jaipur, Hyderabad or other cities.

This means a nationwide movement in crude oil prices does not necessarily translate into identical retail prices across every state.

Crude Oil Prices Remain an Important Factor

International crude oil prices are closely watched because India depends significantly on imported crude to meet its energy requirements.

According to the available data, Brent crude closed at around $88.52 per barrel on August 14 following recent upward movement in international oil prices.

Despite the rise in global crude prices, there was no major change in the quoted retail prices of petrol and diesel across the major Indian cities listed above on August 17.

However, international crude prices are only one of several factors that can influence domestic fuel costs. Currency movements, taxation, refining economics and pricing decisions can also play a role.

How to Check the Latest Fuel Rate Before Refuelling

Petrol and diesel rates may be updated periodically, so motorists should check the prevailing price on the day they plan to refuel.

Rates can be verified through official channels provided by oil marketing companies or directly at the fuel station. This can be particularly useful before filling a full tank or starting a long-distance journey.

For people who drive regularly, keeping an eye on fuel prices can also help in estimating monthly transportation expenses.

What Motorists Should Know on August 17

The key takeaway for August 17, 2026, is that petrol and diesel prices remain broadly stable across several major cities despite recent strength in international crude oil prices.

Delhi petrol stands at ₹102.12 per litre, while Mumbai, Kolkata and Chennai are quoted at ₹111.21, ₹113.51 and ₹107.76 per litre, respectively.

Since fuel rates can differ by location and may be revised, motorists should confirm the latest price applicable at their nearest petrol pump before making a purchase.
