Petrol and Diesel Prices on September 29, 2026

Here are the fuel rates provided for major cities:

Among the cities included in this list, Chandigarh has the lowest petrol and diesel prices, at ₹98.10 and ₹86.09 per litre respectively.

At the other end, Hyderabad has the highest listed petrol price at ₹115.69 per litre, while Thiruvananthapuram has the highest diesel rate at ₹104.40 per litre.

Fuel Prices Are Updated Regularly

Oil marketing companies update petrol and diesel retail rates regularly, with revised prices generally taking effect from 6 AM.

For consumers, this means checking the latest rate before heading to a fuel station can be useful, particularly for people who travel long distances or operate commercial vehicles.

Even a relatively small difference in the per-litre price can become significant when a vehicle requires a large quantity of fuel.

Why Do Petrol and Diesel Prices Differ Across Cities?

Petrol and diesel prices are influenced by several components rather than a single factor.

International crude oil prices are an important part of the equation because crude oil is the primary raw material used to produce petrol and diesel.

India imports a substantial portion of its crude requirements, so movements in international crude prices can influence the broader fuel-pricing environment.

However, a movement in crude oil prices does not necessarily mean that retail petrol and diesel prices will change immediately by the same amount.

Rupee-Dollar Exchange Rate Also Matters

International crude oil transactions are generally denominated in US dollars. As a result, movements in the value of the Indian rupee against the dollar can affect the cost of imported crude.

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

The exchange rate is therefore one of several factors that can influence the underlying cost structure of petrol and diesel.

Taxes Create Differences Between States

Government taxes and levies are another major reason why petrol and diesel do not cost the same everywhere in India.

Central and state-level taxation forms part of the retail price structure. State-level taxes and other local components can differ, which helps explain why a litre of petrol may cost substantially more in one city than another.

For example, the supplied September 29 rates show petrol at ₹98.10 per litre in Chandigarh, compared with ₹115.69 in Hyderabad.

Consumers should therefore avoid assuming that a fuel rate quoted for one city automatically applies across an entire state or region.

Refining and Distribution Costs Also Affect Pricing

Crude oil cannot be directly used as petrol or diesel. It must first be processed at refineries before the finished fuel is transported through the supply chain.

Refining costs, transportation, dealer-related components and other expenses can form part of the eventual retail price.

Demand and supply conditions can also influence the broader energy market.

Why Have Fuel Prices Remained Relatively Stable?

The supplied report points to tax reductions made by the Centre and several states after May 2022 as one factor associated with a period of relative stability in petrol and diesel prices.

International crude oil prices, however, can continue to fluctuate even when retail fuel prices in India remain unchanged for extended periods.

Consumers should therefore distinguish between international crude-price movements and the actual retail price displayed at their local fuel station.

How to Check Petrol and Diesel Prices Through SMS

Consumers can also check fuel prices through the SMS services mentioned in the supplied information.

BPCL customers can send “RSP” to 9223112222.
