Category:

Shell Sirius X 30

High-performance diesel engine oil for marine and industrial high-speed engines

  • Outstanding piston cleanliness ensures reliable operation under severe conditions

  • Excellent protection against bore polishing, blow-by, and oil consumption

  • Superior engine cleanliness by retaining high soot levels in suspension

  • Oxidation resistance twice that of conventional oils, enabling extended drain intervals

  • High TBN-E (17) for acid neutralization and corrosion protection with high-sulphur fuels

  • Approved by MTU (Type II), CWEC, MWM Deutz, and meets Caterpillar 3600 Series and API CF requirements

Global Product Code: 001A9053



Application:

Shell Sirius X 30 is a top-tier Super High Performance Diesel Engine Oil (SHPDO) designed for use in the most demanding high-speed diesel engines operating on distillate fuels. It is especially suitable for fast marine vessels and compact generator sets, offering prolonged protection and service life under extreme operating conditions.

Performance Features & Benefits:

  • Outstanding Piston Cleanliness: Ensures free-running piston rings and optimal reliability even in harsh environments.
  • Anti-Bore Polishing Protection: Effectively controls blow-by and oil consumption while preserving engine efficiency.
  • High Soot Handling Capacity: Retains combustion soot in suspension, maintaining engine cleanliness during long service intervals.
  • Superior Oxidation Resistance: Twice the performance of conventional diesel engine oils under thermal stress.
  • High Reserve Alkalinity: TBN-E of 17 provides long-lasting acid neutralization and corrosion control.

Main Application Areas:

  • High-speed marine diesel engines burning distillate fuels
  • Compact generator sets and other high-output diesel applications

Specifications & Approvals:

  • API CF
  • MTU Type II (High Performance Category)
  • CWEC (Cummins Wärtsilä Engine Company)
  • MWM Deutz (e.g. TBD 620)
  • Meets Caterpillar 3600 Series requirements

Environmental & Safety Information:

  • Use impervious gloves with used oil. Avoid prolonged skin contact and wash with soap and water after exposure.
  • Do not discharge oil into drains, soil, or water. Return used oil to authorized collection points.
  • Safety Data Sheet (SDS) available via inquiry
