Frequently Asked Questions
What is today's Diesel price in Tamil Nadu?
Today's Diesel price in Tamil Nadu is ₹100.74 per liter as of 17 Jul 2026.
Why is Diesel cheaper than Petrol in India?
Diesel is taxed at lower excise duty and VAT levels than petrol by both Central and State governments because it is critical for commercial transport, agriculture, and public transport.
How does Diesel price affect general inflation?
Diesel is the primary fuel used by trucks and commercial transport vehicles. Any hike in diesel rates increases freight and transportation costs, which in turn leads to higher prices for groceries, vegetables, and daily goods.
Is premium diesel better for normal vehicles?
Premium diesel contains additives that clean engine parts and injectors, which can slightly improve efficiency. However, for most normal passenger cars and utility vehicles, standard diesel works perfectly fine.
