How does Quicksilver 25W-40 oil help my 4-stroke outboard perform?

Quicksilver 25W-40 marine oil is formulated for marine environments with additives that support corrosion protection and lubricity under load. It reduces metal-to-metal wear and helps the engine resist scuffing and scoring during normal operation.

• Advanced corrosion inhibitors tailored for salt- and freshwater exposure
• Enhanced lubricity to reduce wear on rotating and sliding components
• Compatible with NMMA FC-W and FC-W Catalyst specifications for marine engines
