The first one is mine. My Fox 35 and 36 like it. So does my OOOLLLLDDDDDD Fox .19.

Start with 64oz. of a standard (I use Wildcat) 10% nitro 18% 0il with the standard 80-20 syn-castor mix.

Add 32 oz (qt.) of 5% nitro 16% oil st. mix.

Add 14 oz. of Castor Oil.

This provides 110 oz. of fuel with 27.8 % oil, being 56% castor, 27.8% Syn. and 7.8% nitro. It works well for me.
