The decrease in petrol and diesel sales in India during December can be attributed to the onset of winter, which led to a decline in air-conditioning demand. Petrol sales of the three state-owned firms fell by 1.4% compared to the previous year, while diesel demand dropped by 7.8%. Despite this, petrol consumption in December 2023 was 7.1% higher than in December 2021 and 21.5% higher than in December 2019.
