Marine Piston S3 30
Pure Tech Marine Piston S3 30 is a multifunctional crankcase lubricant for highly rated medium-speed diesel engines operating on residual fuel. Marine Piston S3 30 has a BN of 30 and is designed for conditions of moderate oil stress.
PERFORMANCE, FEATURES & BENEFITS
Reliable engine performance:
- Extended oil life: Marine Piston S3 30 is a BN 30 oil which has been optimised to resist oxidation and maintain BN in order to reduce the amount of oil sweetening that is required.
- Engine protection: Marine Piston S3 30 has an optimised level of detergency leading to exceptionally clean crankcase, valve deck and pistons. The formulation has been further optimised to reduce deposits in critical areas, e.g. piston undercrown.
- System efficiency: Marine Piston S3 30 has a high detergency/low dispersancy formulation in order to effectively release contaminants and water in centrifugal separators.
Main Application:
Medium-speed industrial or marine propulsion and auxiliary engines, burning residual fuel oils, which create conditions of moderate oil stress. These conditions usually occur:
- In newer engine designs, less than 10 years old
- Where oil consumption is > 1 g/kWh
- Where load factors are <85%
- Where fuels with sulphur <3% are in use
