Diesel rate in Chennai over the last 1 day
Our record for Chennai currently holds a single day: ₹99.55 per Ltr on 17 Oct 2026. A range and a trend need at least two days, so this section fills in as the daily record grows.
This table is built from our own daily record rather than from a third-party feed. That means it starts on the day we began tracking Chennai and grows by one row every night — it is a record of what was actually published, not a reconstructed series.
Diesel rate across Tamil Nadu: where Chennai stands
Cities in Tamil Nadu that sell diesel are quoting within ₹0.39 of one another today — 0.39 per cent, from ₹100.06 per Ltr in Tiruchirappalli to ₹100.45 in Coimbatore. A gap that narrow makes no practical difference, so in Tamil Nadu you can buy wherever is convenient rather than chasing the cheapest city.
Chennai at a glance
Chennai has a population of roughly 80,00,000 and about 63,00,000 registered vehicles, based on our most recent estimate (as of 31 Mar 2024). These are planning estimates rather than a census count, and they are published here so you can judge what the rest of this page means in context.
A city of that size consumes fuel at a scale that a per-litre price hides completely. Multiply any pump price by the number of vehicles on the road and a one-rupee revision stops looking like a rounding error.
How much Chennai spends on diesel in a day
Our working estimate for fuel demand in Chennai is around 1,600 kl/day, again an estimate rather than a metered figure. At today's diesel price of ₹99.55 per Ltr, that demand represents roughly ₹15.93 crore of fuel changing hands in the city every single day.
The arithmetic behind that number is deliberately simple — litres multiplied by the price — and we spell it out so you can substitute your own figure if you have better local data. What it shows is why a small-looking revision matters so much at city scale.
