The cut in petrol prices comes on back of three successive increases since May, while this is the second reduction in diesel rates this month.
Petrol in Delhi will cost Rs 66.62 per litre from tomorrow instead of Rs 66.93 at present. A litre of diesel will cost Rs 50.22 per litre as against Rs 50.93 earlier, Indian Oil Corp (IOC), the nation's largest oil company, said.
Auto fuel rates were last revised on June 16 when prices of petrol were hiked by 64 paise a litre but diesel rates were cut by Rs 1.35 per litre.
Prior to June 16 revision, petrol prices were hiked by Rs 3.13 a litre and diesel by Rs 2.71 per litre on May 16.
State-owned fuel retailers IOC, Bharat Petroleum Corp (BPCL) and Hindustan Petroleum Corp (HPCL) revise petrol and diesel prices on 1st and 16th of every month based on average imported cost and rupee-dollar exchange rate in the previous fortnight.
