Features & Benefits
- Excellent high-temperature detergency
- 250 TBN
- Very high alkalinity to neutralize corrosive acids
- High water stability
- Economical
Problems Solved
Engine deposits in upper ring belts can impact piston ring operation, reducing the ability to properly seal the combustion chamber and leading to combustion gas blowby and oil loss. High-sulfur fuels can be problematic and lead to corrosive wear on engine components, unless engine oils are formulated to neutralize corrosive acids. In marine applications, detergents that are unstable in water can separate, impacting the lubricating oil performance and contributing to engine failures.
Applications
Crankcase lubricants
Marine engine oil
