Why Use Ringfree Plus?
Over time, carbon deposits can build up in your outboard motor, leading to serious performance issues. Though some build up is to be expected, you can avoid performance issues by using Yamalube Ringfree Plus. The additive has proven effective at cleaning combustion deposits, particularly around the piston-ring area.
Not only does the piston-ring area benefit from a good cleaning, so do the carburetors and fuel injection systems. Yamalube Ringfree Plus additionally protects against sulfur compounds found in ethanol blended fuels. Be sure to stock up on this impressive boat engine oil.
