Oli per Motori Marini e Additivi

Marine Engine Oils and Additives

Marine engine oils and additives are essential for ensuring optimal performance, long life, and corrosion protection, especially in salty environments. Products must be specifically designed for marine use, formulated for outboard, sterndrive, or inboard engines, whether diesel or gasoline.


🛢️ Main categories of marine oils

Type of oil Use Characteristics
2-stroke oil (TC-W3) 2T outboard motors High lubricity, low smoke, NMMA TC-W3 specification
4-stroke oil (SAE 10W-30 or 25W-40) 4T outboard and inboard/outboard engines Anti-corrosion protection, stable viscosity, often API SJ or higher
Diesel engine oil (SAE 15W-40 or 10W-40) Inboard diesel Additive against deposits, high thermal resistance
Transmission oil / stern drive Stern drive or reverse gear Antifoam, wear protection, specific for marine gears
Hydraulic oil (ISO VG 32 / 46) Steering systems, flaps, winches Stable viscosity, anti-emulsion, anti-rust

🔧 Useful nautical additives

Additive Function
Fuel stabilizer Prevents gasoline oxidation during storage
Diesel Anti-Condensation Treatment Protects against algae and water in the tank
Injector or carburetor cleaner Improves combustion and reduces consumption
Anti-corrosion oil additive Increases engine protection, useful in marine conditions
Flush engine cleaner Cleans internal circuits before oil changes
