📌 Key points
- Chennai petrol: ₹107.77 a litre; diesel ₹99.55 (4 November 2026, PPAC).
- Tamil Nadu petrol tax: 13% + ₹11.52 a litre (PPAC).
- Tamil Nadu diesel tax: 11% + ₹9.62 a litre.
- Central excise on petrol: ₹11.90 a litre.
- Gap with Delhi petrol: ₹5.65 a litre.
What does a fixed ₹11.52 levy change?
When the oil company price rises, only the 13% part grows. The ₹11.52 stays put, so Chennai prices react less to crude swings than in pure-percentage states such as Karnataka or Telangana.
The flip side is that a fall in crude also brings a smaller cut at the pump.
What sits underneath Tamil Nadu's tax?
Before state tax, the price includes ₹11.90 a litre of central excise, confirmed in a Lok Sabha reply in August 2026, plus the oil company's cost, freight and margin.
The pump owner's commission is set by PPAC at ₹3,144.03 per kilolitre plus 0.870% of the billable price from 1 December 2024, the same nationwide.
How do Chennai's petrol and diesel compare?
Petrol at ₹107.77 and diesel at ₹99.55 put the gap at ₹8.22 a litre. Both fuels carry a fixed state levy, which keeps the two prices relatively close.
Diesel buyers in Chennai therefore save less per litre than in Bengaluru, where the gap is over ₹12.
What should Chennai vehicle buyers keep in mind?
Because the fixed levy dampens price swings, monthly fuel budgets in Chennai are a little more predictable.
Still, compare cost per kilometre across petrol, diesel and CNG models before choosing a used vehicle.
