According to Shenzhen Petro, No. 90 gasoline now costs 3.74 yuan per liter with No. 93 costing 3.95 yuan per liter and No. 97 costing 4.34 yuan per liter.
The price increases take effect Wednesday but retail diesel prices remain unchanged.
The adjustment was made in line with a notice issued by the State Development and Reform Commission to raise retail gasoline prices in China, the company said. Crude oil prices on the international market soared to more than US$55 per barrel and have been close to US$60 this month.
