Malaysia exports crude oil and refined petroleum products to international markets. These exports contribute significantly to the country's revenue and trade balance.

These activities are primarily offshore, with significant operations in Peninsular, Sabah and Sarawak and essential for maintaining domestic oil production and supporting the energy supply chain.

To meet domestic demand and balance refinery inputs, Malaysia imports crude oil and various petroleum products to ensure a stability of supply for refining and consumption needs.

Malaysia has several refineries that process imported and domestically produced crude oil into various petroleum products, such as petrol, diesel, jet fuel, and lubricants. List of refineries are shown in the map below.
