Shell today launched Shell Alexia S4, its most innovative marine engine oil in a generation. Unlike conventional cylinder oils, it can be used across a wide range of vessel and engine types, fuel specifications, loads and climates– from the Antarctic to the Amazon to the Suez Canal. This means vessels no longer need to carry multiple oils. Shell Alexia S4 also works effectively at any vessel speed, including slow and ultra slow– especially important to modern ships that have to vary speeds to reduce fuel consumption and meet strict timetables.
