Hi guy's,

I just bought a saito 72 to my UCD 46 and I am not sure which fuel to use,this is

my first 4 stroke engine.

according to the manual I need 10% to 15% nitro & 20% oil.

can I use less percentage of oil saying 12% oil (most of it

synthetic) and 15% nitro?!

which fuel is more recommended: wildcat 10% nitro & 18% oil OR
byron 15% nitro & 16% oil(synthetic & Castor)
