The chart* posted by Ghokan in the 'Noack of Mobil1 AP" thread (which was locked because of name calling) shows 'New Yubase' to be closer to PAO and GTL than
Gr.III d,c,b and a (whatever those are)…..this leads me to conclude that 'New Yubase' is the most superior of the Gr. III base oils. My understanding is that Yubase is only made by SK lubricants of South Korea….are you saying that any base oil manufacturer can make 'New Yubase'?
* The chart is from the 2nd Asia Pacific base oil conference in Oct. 2007....13 years ago.....so I guess 'New Yubase' isn't so new anymore.....
