Replace Your Centrifugal Separator And Get Up To 2% CII
Improvement
CJC® Engine Lube Oil Filtration for 2- and 4-stroke marine engines. Reduce separator energy use, improve CII by up to 2%, and support IMO decarbonization targets.
PROTECT UPTIME AND REDUCE MAINTENANCE PRESSURE
Why shipowners are switching now
Replacing a traditional centrifugal separator with CJC® offline filtration reduces unnecessary energy demand and helps keep engine lube oil in better condition. That can mean less sludge, less oil consumption, longer oil and component life, and stronger operational reliability.
With tightening CII requirements, EU ETS costs, and FuelEU Maritime penalties, small efficiency gains now have measurable commercial value. Cleaner lube oil reduces internal engine drag, eliminates separator power demand, and helps operators improve fuel performance without major retrofit complexity.
Replace Your Centrifugal Separator And Get Up To 2% CLL Improvement
CJC® Engine Lube Oil Filters reposition lube oil treatment as an operational efficiency lever, helping reduce auxiliary energy use, sludge burden, oil consumption, and maintenance pressure while supporting stronger vessel performance.
PROTECT UPTIME AND REDUCE MAINTENANCE PRESSURE
Cleaner Lube Oil Translates Into Lower Operational Drag Across Marine Engine Systems
Replacing a traditional centrifugal separator with CJC® offline filtration reduces unnecessary energy demand and helps keep engine lube oil in better condition. That can mean less sludge, less oil consumption, longer oil and component life, and stronger operational reliability.
Framed through the wireframe logic of the reference page, this section now behaves like the core operating narrative: why the problem matters, what the filtration change does, and why it deserves a technical and commercial review now.
CII PERFORMANCE
Real World
CII Rating Comparison
Based on 2024 data from a 46,921 DWT MR Tanker (MAN 6S 50MC-C, 11,640 kW) running on HFO. The CJC® filter delivers consistent CII improvements across all trading scenarios - in many cases shifting the vessel from a D to a C rating, or from C to B.
Consumption: 23.6 MT/day at sea (13 kn) • 5.25 MT/day at port

Operational Risks
Why Separator Replacement Becomes a Commercial Issue, Not Just a Maintenance Issue
Unnecessary energy draw
Traditional separator operation adds avoidable auxiliary load at a time when every onboard efficiency gain matters.
Sludge and oil waste
Poor lube oil condition increases sludge handling, oil consumption, and the operational burden around treatment and disposal.
Maintenance cost pressure
Contaminated oil contributes to higher wear, more interventions, and a higher lifetime maintenance burden on critical equipment.
Availability and compliance risk
Lower system reliability and weaker efficiency performance make it harder to protect uptime while improving CII outcomes.
