Why is the THD Higher on the Duel Fuel Firman Generators models than it is on their Tri Fuel Models

I spoke with Firman and here is what they informed me:

The THD or Total Harmonic Distortion as you may know is the amount that a voltage waveform or current is distorted. High THD reduces the efficiency of a portable generator. Low THD is requires for sensitive electronics. Both have the Dual Fuel # 333-H08051 and Tri Fuel have copper coated aluminum wires, the difference is the Tri Fuel has a more precise calibration primarily because of the multiple fuels that it can use.
