I have followed this channel for a bit and had some interesting presentations. He has done virgin oil comparisons and will include a link to one featuring all 5w30 weights of Redline, Pennzoil, Amsoil, and Kendall. Would be interested in people's opinion regarding validity of testing and results. There are similar videos on you tube where he features Schaefer's 9000 5w30 which "beat" Mobil 1 5w30 annual performance. This is the link to playlist and after that just copied link for most recent comparisons.
