Nickolas, yes cool power has 20% oil, but WILD CAT 30 Curtis Youngblood special contains 23% klotz synthetic oil
Cool Heli 30% contains 22% low viscosity oil, I have been using this on my OS FS-70 Ultimate, YS-140 and will be using on my new YS-110. It is strongly recommended for YS. Cool Power Pattern Pro contains 20% high viscosity oil. Check their website if you are not convninced.
