You should dig around and see who is doing that for mopar. Torco is a small company and they do a ton of private label stuff. I used to know who they were doing it for, but that changes and I haven’t kept up.
One I remember is Yamalube two stroke oil. All the Yamaha guys hated Torco but loved the Yamalube. There was some serious butt hurt when I showed them what was in the Yamalube bottle was the exact same stuff as the Torco bottle.
I also know Torco does a bunch of private stuff for the DOD and other alphabet soup government stuff.
And AFAIK, they are the only company producing a GL-6 gear lube.
