I went to Redline's website today to look up a part number and noticed it had changed. This caused me to find out that Redline was bought by Phillips 66 when I wasn't looking. Checking the specs against an older data sheet I had, the HTHS for the 5w20 has dropped from 3.3 to 3.0 (which is a [censored] big change!) and the advertising copy no longer mentions being a PAO/ester base stock.
So what the heck happened here?
