I think it looks more ConocoPhillips / Kendall / Motorcraft
Isn't it they................. ^^^^^^^^^^^^^^^^^^^^^^ who manufactures the SP version of Red Line?
P66. Well, it looks like a lot of oils because they use similar additive systems. I'd say it looks close to Amsoil. Moly is reduced quite a bit and they've jumped to Ca/Mg blend with some Boron.
I'd be curious to run this just to see how it holds up now that it's a Mg/Ca blend with lower SA. I'd like to see how UOA's look with RL SP vs their old school high Ca blends.
