Diesel prices across India, per litre, refreshed twice a day from published pump prices. Pick a city to see its own rate and how it has moved. State VAT is the largest difference - it is set by each state, not centrally - followed by freight from the nearest depot and local levies. Rupix publishes these figures for information only.
