Petrol Diesel Price Today, August 18, 2026: Fuel prices remained unchanged across several major Indian cities on Tuesday as oil marketing companies released the latest petrol and diesel rates. While there was no broad revision in retail prices, motorists continue to see significant differences from one city to another because of variations in state taxes, VAT and local levies.

Petrol remains considerably more expensive in states such as Madhya Pradesh, Rajasthan and Bihar compared with places like Delhi, Haryana and Chandigarh. Since fuel costs directly affect household budgets, transport expenses and business operations, checking the latest city-wise rates can help consumers plan their spending better.

City-Wise Petrol and Diesel Price Table

Why Are Fuel Prices Different Across States?

Petrol and diesel prices depend on several components, including the international cost of crude oil, the rupee-dollar exchange rate, refining costs, freight charges, dealer commissions and taxes.

State taxes and VAT are among the biggest reasons why retail fuel prices vary across India.

Even when oil marketing companies do not announce a nationwide price change, local taxation can keep petrol and diesel significantly costlier in one city than another.

How to Check Fuel Prices by SMS

Consumers can also check current fuel rates through SMS-based services offered by oil companies.

For Indian Oil customers, the commonly used format is:

RSP Dealer Code

The message can be sent to the designated Indian Oil fuel-price SMS number.

For example, consumers can enter the dealer code of the relevant petrol pump after “RSP” to receive the latest petrol and diesel price details for that outlet.

Users can also check nearby fuel stations and daily rates through the IndianOil ONE app.

Since SMS numbers and service formats may be updated from time to time, consumers should verify the latest official instructions before using the service.

What Motorists Should Keep in Mind

Fuel prices can change depending on crude oil movements, currency fluctuations, government taxes and local levies. This is why checking the latest rate before refuelling can be useful, especially for people who travel frequently or manage commercial vehicles.

For August 18, 2026, petrol and diesel prices remain unchanged in the major cities listed above, but large regional differences continue.

Disclaimer: Fuel prices may vary by city, petrol pump, taxes and local charges. Consumers should verify the latest rate with their nearest authorised fuel station or the official app or website of the concerned oil marketing company.
