Performance, Features & Benefits

• Extended oil life
  Shell Mysella S3 Z is highly resistant to nitration and oxidation, which can cause filter deposits, viscosity increase and acid build-up.
• Engine protection
  The very low ash formulation of Shell Mysella S3 Z enables potentially longer spark plug life resulting in increased time between replacements. In addition, the excellent Anti-Scuff / Anti-Wear Protection protects and minimizes scuffing during the running-in (break-in) period including high BMEP engines.
• Engine efficiency
  Shell Mysella S3 Z combines a low tendency to form carbon with a strong detergency system, to avoid port plugging in 2-stroke (2-cycle) engines which essentially eliminates the need to clean cylinder ports between overhauls. The “very low ash” formulation enables spark plugs to remain almost “as new”, with their lifetime limited only by spark gap erosion. It also virtually eliminates detonation and pre-ignition, due to the absence of deposit “hot spots”.
