Formulated for 2 - stroke engines. High performance low ash lubricant. For direct injection and high power outboard engines. ideal for modern outboard engines with direct injection of high power for which oils are required with high lubricity, high thermal stability and performance much higher than those required by NMMA TC - W3. .The exclusive Bardahl Polar Plus anti - friction formula forms a lubricating molecular film which, when chemically fixed to the metal, creates a permanent protection barrier against friction and wear to a much greater extent than conventional lubricants. Details: Maximum cleaning of piston, combustion chamber and spark plugs Exceptional effectiveness in controlling high temperature deposits, avoids the bonding of elastic bands "Ring Sticking" and abnormal wear from "Ring Jacking" Superior protection against rust, corrosion and wear Smokeless technology Significantly exceeds the performance defined by the NMMA TC - W3 specification to meet the requirements of Direct Fuel Injection (DFI) outboard engines 4 Lt
