Best Fuel for Saito .56 GK at 7,500 Feet
I currently live and fly in Mexico City and am flying regularly at 7,500 feet. I use a Saito .56 GK engine but have limited fuel options. They are: YS 20/20, Bayron 15-16, Powermaster 15-18, or Powermaster 20/20. Some people have recommended I use an 18-20% oil content, but I wonder if this is necessary considering this is a four-cycle engine with oil added to the crankcase. One person recommended Cool Power 15% or Cool Power 30% heli for the most power. Please let me know what you know about the oil content needed and what fuels work best (mixture and brand) for these altitudes.
