Unioil Petroleum Philippines, Inc., simply known as Unioil, is a Philippine downstream oil company.

History

Unioil Petroleum Philippines, Inc. was established in 1966 by the Chinese-Filipino Co family as a lubricant manufacturer and distributor with a facility in Valenzuela. Unioil expanded to fuel trading, distribution, and retailing when the Philippine petroleum industry was deregulated in 1998.[1][2][3][4]

In 2003, Unioil established an oil depot in Mindanao. The company has 30 service stations at around this period.[5]

Unioil still has 30 service stations in Metro Manila, Cavite, Pampanga and Laguna in 2012.
