Lucas Oil High Performance Semi-Synthetic 2-Cycle Oil

Lucas Oil High Performance Semi-Synthetic 2-Cycle Oil is engineered to deliver professional-grade protection for gasoline-powered two-stroke engines across a wide range of powersports, marine, and outdoor power equipment applications. Specifically developed to provide long, trouble-free engine life, this oil line combines the benefits of mineral and synthetic base stocks with a proprietary additive package to keep two-stroke equipment running cleaner, stronger, and longer.

Advanced Smokeless Formula

At the heart of this product line is Lucas Oil's advanced smokeless formula — a precision blend of mineral oil, synthetic oil, and a low-ash additive package with fortified dispersant inhibitors. The result is a more thorough, cleaner fuel combustion cycle that produces more power with significantly fewer emissions, making it well-suited for environments where prolonged exposure to exhaust is a concern.

Key Features:

• Semi-synthetic formulation combining mineral oil and synthetic base stocks for a balanced performance profile across all operating temperatures
• Low-ash additive package with fortified dispersant inhibitors minimizes carbon buildup on pistons, rings, crowns, and under-crown areas
• Ashless detergent inhibitor package reduces spark plug fouling, pre-ignition, ring sticking, and combustion chamber deposits
• Cleaner exhaust ports and spark plugs for more consistent, reliable engine performance over time
• Easy-mix formula blends smoothly with gasoline at any temperature for hassle-free preparation
• Reduced friction for smoother piston travel, improved power output, and lower fuel consumption
• Compatible with oil injection systems and premix applications up to 50:1
• Meets ISO GD and JASO FD standards and exceeds API TC requirements
• Surpasses OEM requirements from major outboard manufacturers including Mercury, Evinrude, and Johnson
• Suitable for use in both air-cooled and liquid-cooled two-stroke engines
