Yeah, I realize why they said what they said. But I also stated in my post that in my experience, the SUDT, which is synthetic, also handles the heat better than UDT. The benefits of synthetic are seen in BOTH extreme heat & extreme cold. I run synthetic in all of my equipment and vehicles, and have operated them from -30* to 108* F.
I also mentioned that the UDT seems to overheat, as evidenced by the smell and the decrease in performance, whereas the SUDT doesn't seem to overheat or lose performance.
SUDT is most definitely NOT synthetic. This has been discussed numerous times over many years.
