Does Yamalube 2M (for 2-cycle) contain Ring Free? Or does Yamaha keep this a secret?
 
It is my understanding that ring free is a fuel additive (like seafoam). It is used to clean off carbon buildup. Yamalube or other quality oil also works on carbon buildup by helping prevent it.
 
the owners manual says to use both products, which leads me to believe Yamalube doesn't contain both products. I use both.
