Is Chevron working on getting the Delo 400 synthetic CI-4 rated? I see it's only CG rated, have they given up on it? Hard to believe they would give up a chunk of market like that to Mobil and Shell. I know Valvoline, Redline, and Amsoil, all make syn, but they don't seem to have the market of Mobil and Shell. Idle curiosity here.
