Diesel prices hit their highest in India since 2013 after they were hiked for a sixth consecutive day.

The prices of diesel and petrol were hiked effective Tuesday morning across Delhi, Mumbai, Kolkata and Chennai.

Petrol prices reached Rs 74.40 a litre, while diesel rates touched Rs 65.65, the highest-ever since May 2014 in Delhi, according to Indian Oil Corporation (IOC).

In Kolkata, Mumbai and Chennai petrol prices climbed to new highs of Rs 77.10, Rs 82.25 and Rs 77.19 respectively.

Diesel prices in the three cities touched record highs of Rs. 65.65, Rs. 68.35, Rs. 69.91 and Rs. 69.27 respectively.

The petrol and diesel prices across the country are revised on a day to day revisions by state-run oil marketing companies which is determined by international crude oil price.

The rise in crude oil prices is due to the ongoing supply cut of oil by the Organisation of the Petroleum Exporting Countries (OPEC), coupled with a strong global demand for crude causing a hike in petrol and diesel prices in India.
