Sierra 18-9690-3 is a premium synthetic blend marine engine oil formulated specifically for 4-stroke outboard and sterndrive applications. This advanced lubricant combines high-quality synthetic base oils with a precisely balanced additive system that exceeds FC-W (Four-Cycle Water-Cooled) certification requirements set by the National Marine Manufacturers Association (NMMA).
Key Features:
This marine-grade oil provides enhanced protection against the challenging conditions found in saltwater and freshwater environments, including moisture contamination, extended idle periods, and varying load conditions. The synthetic blend formulation helps maintain engine cleanliness, reduces friction, and extends engine life. Each container holds one gallon of oil, providing convenient quantity for routine maintenance.
