Overview
LENJ oil is an engine oil for medium-speed four-stroke diesel engines. Grades: SAE 30, SAE 40. Its published base number is 9 mg KOH/g.
In marine and stationary diesel service, the base number is matched to the sulphur content of the fuel: higher-sulphur fuels need a higher base number to neutralise the acids formed in combustion. The specification table lists each grade with its test methods.
Application
