Why diesel costs ₹100.66 in Theni
The pump price is built up in layers: the oil company's base price (which follows crude oil and the rupee), freight to the pump, the central excise duty, the dealer's commission, and the state's VAT, which is charged on top of everything else. VAT is why diesel costs a different amount in each state, and freight from the nearest depot is why it differs between districts of Tamil Nadu. Prices have been revised daily, at 6 am, since June 2017.
