PETRO-FLO HIGH TBN MARINE MOTOR OIL SYNTHETIC BLEND is a premium quality synthetic blend mid ash marine motor oil formulated with a carefully selected blend of high performance additives and a mix of mineral and synthetic base oils. Provides complete protection for marine engines and is designed to exceed the lubrication requirements of the most modern diesel and gasoline engines used in boating applications. Provides excellent protection for both four-cycle gasoline engines, as well as two- and four-cycle high performance diesel engines, minimizes carbon deposits in the piston ring zone, resulting in less ring wear and less cylinder bore polishing. The benefits are less oil consumption, less ring breakage and less piston skirt scuffing. The acid neutralizing additives help to reduce corrosive wear, provides excellent protection against rust, sludge, and low-temperature deposits which are more commonly a problem in gasoline engines.
