Mercury Opimax DFI oil 3.78 L
Optimax/DFI Outboard Engine Oil is formulated specifically for Mercury OptiMax and other Direct Fuel Injection (DFI) two-stroke engines that operate under intense pressure and extreme combustion temperatures. These high-performance engines demand an oil that delivers rapid lubrication, reduced carbon buildup, and enhanced piston and ring protection-attributes engineered into every bottle of premium DFI oil. Its low-ash formulation supports cleaner burning, preventing harmful deposits in injectors, spark plugs, and air compressors, which is critical for maintaining the reliability and fuel efficiency that OptiMax engines are known for.
This category includes oils designed to meet Mercury’s stringent DFI requirements, ensuring maximum durability for engines used in demanding marine environments such as offshore fishing, commercial operations, and high-speed recreational boating. Whether maintaining classic OptiMax V6 models or modern DFI platforms, these oils provide superior wear protection, minimized smoke, and consistent performance across a wide RPM range. Engineered for optimized lubrication under high load and low-emissions operation, Optimax/DFI oils help extend engine life while supporting smooth throttle response and clean combustion.
