SEGLÜR SAE 50 TBN 50 API CF
High-BN Crankcase Lubricant for Medium-Speed Diesel Engines
Overview
SEGLÜR SAE 50 TBN 50 API CF is a high-performance, high-base number (BN 50) trunk piston engine oil designed for use in medium-speed marine and industrial diesel engines operating on residual fuel oils under very high thermal and mechanical stress.
Formulated using high-quality base oils and advanced detergent-dispersant additive technology, it ensures excellent deposit control, outstanding resistance to contamination, and enhanced engine cleanliness.
Benefits & Advantages:
- Excellent protection against corrosion, especially from acidic combustion by-products in residual fuel
- High thermal and oxidation stability for long oil life in hot engine environments
- Strong detergency to prevent piston under-crown and ring groove deposits
- Excellent viscosity control – resists thickening from contaminants
- Reduces maintenance costs through cleaner engine operation
- Excellent wear protection even at extended oil drain intervals
- Maintains oil film strength under high load and pressure conditions
Application:
For marine trunk piston engines operating on residual fuels; also suitable for gearboxes, stern tubes, and high-BN applications in low oil consumption engines.
Meets & Exceeds:
- API CF
- Suitable for use where lubricants with high TBN and ash content are recommended
- Meets performance needs of engine builders such as MAN, Wärtsilä, MAK, and Pielstick for older-generation residual-fueled engines
