Petrol Diesel Price Today, September 30, 2026: Crude oil prices have moved higher in the international market, with Brent crude trading close to the $100-per-barrel level. Despite the increase in global crude prices, petrol and diesel rates in India have not seen a fresh nationwide revision in the latest update cited in the report.

Oil marketing companies have released the latest fuel prices for Wednesday, September 30. Motorists planning to refuel should check the applicable rate in their city because petrol and diesel prices can vary significantly across states and cities due to differences in local taxes and other costs.

In Delhi, petrol is listed at ₹102.12 per litre, while diesel is available at ₹95.20 per litre. Mumbai continues to have considerably higher fuel prices, with petrol at ₹111.21 and diesel at ₹97.83 per litre, according to the supplied rates.

Petrol and Diesel Prices Remain Unchanged in Latest Update

Despite renewed pressure in the international crude oil market, the latest domestic rates cited in the report do not show another nationwide increase in petrol and diesel prices.

Earlier, petrol prices had risen by up to ₹2.61 per litre, while diesel had become costlier by up to ₹2.71 per litre, according to the supplied information.

No fresh nationwide revision has been reported after that increase.

Consumers should remember that petrol and diesel rates can differ from one location to another. Even neighbouring cities can have different prices because of state-level taxation, local levies, freight costs and other components of fuel pricing.

Petrol Diesel Price Today: Check City-Wise Rates

Here are the petrol and diesel prices supplied for major Indian cities on September 30:

Among the cities listed, Thiruvananthapuram has the highest petrol rate at ₹115.49 per litre as well as the highest diesel rate at ₹104.40 per litre.

Lucknow, meanwhile, has petrol at ₹101.86 per litre, while diesel is listed at ₹95.36.

Delhi Fuel Price Today

Consumers in the national capital are paying ₹102.12 per litre for petrol and ₹95.20 per litre for diesel, according to the rates provided.

For someone purchasing 10 litres of petrol, the fuel cost at the quoted rate would be approximately:

₹102.12 × 10 = ₹1,021.20

Similarly, 10 litres of diesel would cost approximately:

₹95.20 × 10 = ₹952

The actual amount paid at a fuel station will naturally depend on the quantity purchased.

Mumbai Petrol Remains Above ₹111 Per Litre

Fuel continues to be comparatively expensive in Mumbai.

Petrol is listed at ₹111.21 per litre, while diesel is at ₹97.83 per litre.

At these rates, buying 20 litres of petrol would cost approximately ₹2,224.20, while the same quantity of diesel would cost about ₹1,956.60.

This difference illustrates why motorists should check local prices rather than relying on a single nationwide petrol or diesel figure.

Jaipur Petrol Price Stands at ₹112.66

In Jaipur, petrol is listed at ₹112.66 per litre, while diesel is priced at ₹97.78 per litre.

A vehicle owner purchasing 30 litres of petrol at the supplied rate would spend approximately ₹3,379.80.

For 30 litres of diesel, the corresponding cost would be approximately ₹2,933.40.

Fuel expenses can therefore make a noticeable difference to monthly household budgets, particularly for people who travel long distances regularly.

Crude Oil Moves Close to $100 a Barrel

The biggest international development affecting the fuel market is the renewed rise in crude oil.

According to the supplied market information, Brent crude was trading at around $99.46 per barrel on the morning of September 29, 2026.

A day earlier, it was quoted at approximately $99.25 per barrel.

This means Brent crude has moved close to the psychologically important $100-per-barrel level.

Higher international crude prices are closely watched in India because the country imports a substantial share of the crude oil needed to meet domestic consumption.

However, a rise in crude oil does not necessarily translate into an immediate or identical increase in petrol and diesel prices at retail pumps.

Why Don't Petrol Prices Rise Immediately With Crude Oil?

Crude oil is only one of several components that ultimately influence the retail price paid by consumers.

The rupee-dollar exchange rate is important because international crude purchases are generally denominated in US dollars. A weaker rupee can increase import costs even when the dollar price of crude remains unchanged.

Refining costs, transportation expenses, dealer commissions and central and state taxes also contribute to the final retail price.

This is why a change in international crude oil prices does not always result in an immediate one-to-one change at petrol pumps.

Why Are Petrol and Diesel Rates Different Across Cities?

A driver travelling between two states may notice a significant difference in fuel prices even when the base fuel is supplied by the same oil marketing company.

State-level taxes and local cost structures are major reasons for these differences.

For example, the supplied petrol rate is ₹102.12 per litre in Delhi but ₹115.49 in Thiruvananthapuram—a difference of ₹13.37 per litre.

For a 40-litre petrol purchase, that price gap would amount to more than ₹500.

This makes city-wise fuel rates particularly relevant for commercial drivers and people travelling long distances between states.

Could Petrol and Diesel Become More Expensive?

The recent rise in Brent crude has renewed attention on domestic fuel prices, but it would be premature to conclude that petrol and diesel prices will definitely increase.

If crude oil remains elevated for an extended period, it can increase cost pressure on the domestic fuel market. Currency movements and other pricing factors can also influence the situation.

However, the eventual retail price is determined by several factors, and a future revision cannot be predicted solely from one day's crude oil movement.

For now, according to the information provided, there has been no fresh nationwide change in petrol and diesel prices in the latest update.

Check Fuel Rates Before Filling Your Tank

Petrol and diesel prices are generally updated regularly, and consumers should check the latest applicable rate in their own city before refuelling.

As of the September 30 rates supplied, petrol is at ₹102.12 per litre in Delhi, ₹111.21 in Mumbai, ₹113.47 in Kolkata and ₹107.87 in Chennai.

Meanwhile, Brent crude's movement towards $100 per barrel remains an important factor to watch.

If global crude prices stay elevated, pressure on India's fuel market could increase, but any change in retail petrol or diesel rates will depend on the pricing decisions and other cost factors applicable at that time.
