Product Details

Sierra 18-9440-2 is a premium 25W-40 four-cycle marine engine oil specifically formulated for the demanding conditions faced by sterndrive and inboard engines. This synthetic blend combines high-grade synthetic and mineral base stocks with advanced additives designed to protect your marine engine in extreme operating environments.

Key Features:

  • Synthetic blend formula provides superior protection compared to conventional oils
  • Advanced corrosion protection guards internal components against saltwater and freshwater exposure
  • Reduces friction and wear on critical engine parts for extended engine life
  • Maintains viscosity and resists thermal breakdown under high RPM, extreme temperatures, and heavy loads
  • Extensively tested to meet the performance demands of marine applications
  • FCW (Four-Cycle Water-Cooled) certified for marine use

Each quart bottle delivers reliable lubrication for routine oil changes and top-offs. Sierra marine oils are engineered to help your inboard or sterndrive engine run smoothly season after season, whether you're cruising or running at full throttle.
