Factors Influencing Fuel Prices:

Several factors contribute to the price of fuel at the pump:

• Crude Oil Costs: The cost of crude oil is a primary driver, influenced by global demand, refining capacity, and geopolitical events.
• Taxes: Central and state government taxes form a significant portion of the retail price.
• Refining and Distribution: The costs associated with refining crude oil and distributing fuel to retail stations also impact prices.
• Currency Fluctuations: Exchange rates, particularly the US dollar, play a role as crude oil is often traded in USD.

Regional Price Differences

Fuel prices vary significantly across different regions due to factors like state taxes, transportation costs, and local market conditions. For example, West Coast states in the U.S. typically have higher prices due to stricter environmental regulations and limited pipeline infrastructure. In India, prices differ between states due to varying state taxes and transportation costs.

Note: All prices are subject to change and it is advisable to check with local fuel stations for the most up-to-date rates.
