Why Do Petrol and Diesel Prices Differ Between Cities?

Many consumers wonder why petrol or diesel can be significantly more expensive in one city than another even though the basic fuel is the same.

Retail fuel prices are influenced by several components. These can include the underlying fuel cost, central levies, state taxes, dealer-related components and transportation expenses. State-level taxation is one of the reasons retail prices can vary across different parts of the country.

As a result, a consumer in Delhi may pay a different amount for a litre of petrol compared with someone filling up in Mumbai, Kolkata or Chennai.

International crude oil prices and currency movements can also influence the broader cost environment for petroleum products.

How to Check the Latest Petrol and Diesel Price in Your City

Fuel prices can be checked through the official channels provided by India's oil marketing companies. Consumers can use the websites, mobile applications or applicable SMS services of their fuel retailer to verify the latest price for their location.

Checking the rate before filling the tank can be particularly useful when travelling between cities or states, as the difference in per-litre prices may add up on a large refill.
