What is the best gas to use in Yamaha gas carts?
93 or higher octane gasoline does nothing that 89 octane can't do in an engine designed to run on 89. That is a fact. Doesn't matter if it's a cart engine or a V8. Higher octane allows the fuel to combust slower, nothing more. If an engine is built and tuned to spec for low octane fuel, that's all it needs. Anyone telling you different is blowing smoke, not facts. Also, all modern engines have hoses and components designed to withstand ethanol enhanced fuels. Save $$$ and do what the owners manual states.
