ExxonMobil has commissioned a new base stock production unit at its Singapore refinery, converting heavy residue into high-value lubricant base oils. This move marks a strategic shift toward value-added derivatives within the downstream spectrum, as refiners face compressed margins on fuels.

The new unit enables the refinery to monetize residual streams that might otherwise fetch lower returns as fuels. Given strong global demand for high-performance lubricants, this capacity adds resilience against volatility in fuel markets. The Singapore facility already operates in an integrated hub, serving marine, aviation, and petrochemical needs.

With the new base stock capability, Exxon positions itself to compete more strongly in lubricant markets, diversify revenue, and buffer against cyclical swings in diesel/gasoline margins. Turning what was once a lower-margin residue into a premium product is an increasingly common strategy among refiners worldwide.
