no sir i have not but plan on giving it a try if it's price-competitive with the amsoil product i'm now using. i haven't studied up on it but suspect the only difference between the oil you mentioned and amsoil 20-50 cycle oil is the type and quantity of oil-shear additives in it. the type and quantity would potentially make this oil you mentioned a tad more gear-specific and maybe add some lifespan. just my suspicions.
