Marine gas oil compositions corresponding to fuels and/or fuel blending components are provided that can provide improved friction properties within an engine. Addition of lubricant base stock to a marine gas oil composition can reduce frictional losses within an engine during operation. The benefits in reduction of frictional losses can be observed based on the difference between the indicated mean effective pressure and the actual work delivered by an engine, where the difference corresponds to the frictional mean effective pressure.

Marine fuel compositions with reduced engine frictional losses

Heavy hydrotreated gas oil compositions are provided, along with marine fuel oil compositions and marine gas oil compositions that include a substantial portion of a hydrotreated heavy atmospheric gas oil. The hydrotreated heavy atmospheric gas oil can correspond to a gas oil with a relatively low viscosity and an elevated paraffin content in a narrow boiling range which results in a relatively high cloud point and/or pour point.
