I've never seen the oil, so I took a quick look at the product data sheet and the SDS. It meets the requirements of FD/EGD. Since it is generally unlikely that a conventional 'dino' oil such as simple 30 viscosity oil, or bright stock will meet the smoke requirement, it looks like it may be a Group III oil.

"The petroleum base oils contained in this product have been highly refined by a
variety of processes including severe hydrocracking/hydroprocessing to reduce aromatics and improve performance
characteristics. All of the oils meet the IP-346 criteria of less than 3 percent PAH's and are not considered carcinogens"
Since some countries don't consider Group III to be synthetic, they may simply have chosen not to call it a synthetic.
Other locations gladly call fresh from the well Crude Oil a synthetic.... (a little joke)
EGD/FD oils generally perform quite well when adequate oil is used.
