Fuel octane requirements are engine, not airframe-specific. The simplistic answer is: Higher compression, higher octane (higher tetraethyl lead content) required to preserve adequate detonation margins. Use a fuel of unknown characteristics at your own (and your passenger's) risk. Further, fuels containing an alcohol such as ethanol may be incompatible with the fuel system - just had to replace the Holley carb. on my boat (small-block Ford V-8) after about 8 - 9 years of gas with 10% ethanol content.
