I found a 10/10 fuel that is ez for me to get at my hobby shop.. but there is allot more caster oil then senthetic Im not sure one what the % is on it but the woman on the phone from the co. said that it is mostly caster, very little sinthetic.. Will this work? Is there a problem running a fuel with little or no senthetic? (I know Im not spelling it right but i hope you can see what Im trying to ask)
