Using Friction Reducing Concentrate (FRC) with existing marine oil in DG sets lowers friction, reduces heat, and minimizes wear during continuous running. It improves fuel efficiency, stabilizes engine performance, and extends component life under harsh marine conditions. When applied as a protective layer during standby or long idle periods, FRC prevents corrosion, rust, and surface pitting on moving parts. It keeps components pre-lubricated, ensuring smoother start-up and reducing the risk of damage when the marine engine is brought back into operation.
