That is correct. After reading up on this, NGLI 2 only refers to viscosity. Grease typically has (1) a mineral oil, (2) a thinkener, (3) additives. All thickeners are not compatible. For example clays and metal soaps are both used as thickeners and they are not compatible. I remain perplexed as to why a manufacturer would not tell you the exact type of grease they use.My understanding is the NGLI #2 is a consistency or thickness of the grease. Not what it is made out of.

I am leaning towards using Superlube since another owner has had good results. Also it is safe for food contact in case I am eating and need to work on the lathe. Or perhaps turn down a hot dog to fit in a bun?

Superlube claims compatability with lithium greases so it may still be an option.Sooo....
I got an email back today from South Bend Lathe Company. They now indicate that a lithium based grease should be used! I like that, and the prompt reply. They plan to add this information to future revisions of the manual.
I also found that Superlube uses "Fumed silica" as the thickener.
I guess the Mobile 1 is back in.
