Petrol prices in the national capital crossed Rs 97 a liter and diesel neared Rs 88 after fuel prices were raised yet again.
Petrol price was hiked by 29 paise per liter and diesel by 28 paise, according to a price notification of state-owned fuel retailers.
The hike -- 27th in seven weeks -- pushed fuel prices across the country to new historic highs.
In Delhi, petrol hit an all-time high of Rs 97.22 a liter, while diesel is now priced at Rs 87.97 per liter.
Fuel prices differ from state to state depending on the incidence of local taxes such as VAT and freight charges.
And because of this, petrol retails at over Rs 100 per liter mark in eight states and union territories -- Rajasthan, Madhya Pradesh, Maharashtra, Andhra Pradesh, Telangana, Karnataka, Jammu and Kashmir, and Ladakh.
Among the metros, petrol is already above Rs 100 in Mumbai, Hyderabad, and Bengaluru. In Mumbai, petrol now costs Rs 103.36 a litre and diesel comes for Rs 95.44.
Sri Ganganagar district of Rajasthan near the India-Pakistan border was the first place in the country to see petrol hitting Rs 100 a liter mark in mid-February and earlier this month it also earned the distinction of diesel crossing that psychological mark.
Petrol in the city is sold at Rs 108.37 a liter - the highest rate in the country, and diesel comes for Rs 101.12.
Rajasthan levies the highest VAT on petrol and diesel in the country, followed by Madhya Pradesh, Maharashtra, Andhra Pradesh, and Telangana.
The hike on Sunday was the 27th increase in prices since May 4, when state-owned oil firms ended an 18-day hiatus in rate revision they observed during assembly elections in states like West Bengal.
In 27 hikes, petrol price has risen by Rs 6.82 per liter and diesel by Rs 7.24 a liter.
Oil companies revise rates of petrol and diesel daily based on the average price of benchmark fuel in the international market in the preceding 15 days, and foreign exchange rates.
International oil prices have firmed up in recent weeks in anticipation of demand recovery following the rollout of vaccination programmes by various countries. Also, the rupee has weakened against the US dollar, making imports costlier.
