The "0W" Redline Oils don't really seem to have the huge HTHS advantage that their other oils do:
Redline 0W20 = 2.7
Amsoil 0W20 = 2.8
PP 0W20 = 2.6
M1 0W20 = 2.6
etc, etc
No it's not huge but it is better than the rest. I don't count Amsoil because it's almost a 30 wt oil with a 100C vis of
9 cSt.
I like it for it's polar POE content, high P level of 1200ppm, 950 ppm of Moly, high NOACK of 9% and the fact that it is light with a 40C vis of 43 cSt, in fact I wish it was lighter.
If it's lighter than you like you can simply blend in some 0w30 to get whatever vis you want.
Negatives; as mentioned I wish it had a lower 40C vis and a higher VI (at 166 it's good but not great; PP is 175).
