Fuel prices in India are updated regularly, with the latest rates generally becoming applicable from 6 AM.

According to the latest rates, petrol in New Delhi is priced at ₹102.12 per litre, while diesel costs ₹95.20 per litre. Mumbai motorists are paying ₹111.18 for a litre of petrol and ₹97.83 for diesel.

Here is a detailed look at fuel prices across major Indian cities on October 4, 2026.

Petrol and Diesel Prices on October 4, 2026

Among these cities, Chandigarh has comparatively lower petrol and diesel rates, while Hyderabad and Thiruvananthapuram are among the locations where motorists are paying higher prices.

Consumers should note that fuel rates can vary between cities and even between locations because of differences in state and local taxes and other applicable charges.

Why Do Petrol and Diesel Prices Differ Across Cities?

One of the most common questions among motorists is why petrol or diesel can cost significantly more in one city than another.

A major reason is the difference in taxes and levies imposed in different states. Although the basic cost of fuel is influenced by international crude oil prices, the final amount paid at a fuel station includes several other components.

This is why petrol and diesel prices in cities such as Delhi, Mumbai, Hyderabad, Jaipur and Chandigarh are not identical.

Crude Oil Prices Influence Domestic Fuel Costs

Crude oil is the principal raw material used for producing petrol and diesel. India imports a substantial portion of its crude oil requirements, making international crude prices an important factor for the domestic fuel market.

When crude oil becomes more expensive internationally, the cost of procuring raw material can increase. Conversely, lower international crude prices can ease input costs.

However, movements in international crude oil prices do not necessarily translate into an immediate or identical change in retail petrol and diesel prices because several other factors affect the final price.

Rupee-Dollar Exchange Rate Also Matters

The exchange rate between the Indian rupee and the US dollar is another important factor.

International crude oil transactions are largely denominated in dollars. Therefore, when the rupee weakens against the US currency, Indian importers may need to spend more rupees to purchase the same quantity of crude oil.

A stronger rupee can have the opposite effect, although the eventual impact on consumers depends on other components of fuel pricing as well.

Taxes Make Up a Significant Part of Retail Fuel Prices

Central and state-level taxes are another major component of the amount consumers pay at petrol pumps.

Tax structures vary across states, which helps explain why motorists can encounter different prices when travelling from one state to another.

Changes in taxation can therefore influence fuel prices even without a major movement in international crude oil rates.

Refining and Distribution Costs Affect Prices

Crude oil cannot be used directly as petrol or diesel. It must first be processed at refineries.

The cost of refining depends on several factors, including the quality of crude oil, refinery operations and processing expenses.

After refining, petrol and diesel must also be transported to distribution facilities and retail outlets. Transportation and dealer-related costs are therefore additional elements in the final retail price.

Demand and Supply Can Influence the Market

Fuel demand is another factor that can affect broader price trends. Petrol and diesel consumption can rise during periods of increased travel, economic activity or seasonal demand.

On the supply side, global production decisions, geopolitical tensions and disruptions to oil-producing regions can influence international crude oil prices.

Together, these factors can ultimately affect the economics of India's fuel market.

Why Have Fuel Prices Seen Long Periods of Stability?

Petrol and diesel prices witnessed significant changes around 2022, including reductions in taxes by the central government and some states.

Since then, retail prices in many locations have gone through extended periods without major revisions despite fluctuations in international crude oil markets.

This does not mean fuel rates are permanently fixed. Consumers should continue checking current prices because rates can be revised depending on pricing decisions and market conditions.

How to Check Petrol and Diesel Prices Through SMS

Consumers can also check fuel prices applicable to their location using SMS services offered by major oil marketing companies.

Indian Oil customers can send RSP along with the relevant city or dealer code to 9224992249.

BPCL customers can send RSP to 9223112222.

HPCL customers can send HP Price to 9222201122.

Users should follow the latest instructions provided by their respective oil marketing company, as SMS formats or service numbers may be updated.

What Motorists Should Check Before Refuelling

Fuel prices directly affect household transportation expenses as well as businesses that depend on road transport. Changes in diesel rates can also influence commercial transportation costs, although the eventual impact on goods and services depends on several other factors.

For October 4, motorists in New Delhi are paying ₹102.12 per litre for petrol and ₹95.20 for diesel. In Mumbai, the respective prices are ₹111.18 and ₹97.83, while Jaipur has petrol at ₹112.66 and diesel at ₹97.78 per litre.

Since rates vary across locations, motorists should check the latest price applicable at their local fuel station before filling their vehicle.
