Castor Oil... geez, I haven't heard that since 1964!! Castor Oil is lubricant... you mix it with gas!! Forget Amsoil.... !! I think we mixed castor oil with nitromethane! Gawd... I loved nitro!! Methanol was throttle sluggish... but nitro was right there all the time.... Nitro was a little hard on the top of the pistons though.Hello
I am trying to get the smell you get when you go to snowmobile races. I found some castor oil that dosen't contain any sugar in it. I am wondering if I can mix it with my gas or is it better to mix it with my Amsoil.
