Performance, Features & Benefits

• Extended oil life
  Significantly prolongs oil life by resisting oxidation and nitration, the high level of TBN (total base number) neutralises acids and provides corrosion protection, even when “sour” gases are in use.
• Engine protection
  Shell Mysella S3 S is formulated with an optimised level of ‘ash’ components which helps prolong the life of valves in engines which prefer a medium ash oil. With a maximum phosphorus content of 300 ppm Shell Mysella S3 S is compatible with engines equipped with emission catalysts.
