FYI - #1 & #0 are grades of "tackyness and viscocity" that are industry standards ... known as the NLGI standards that rate grease from runny to very thick(waxy substance) ... NLGI grade 00, Grade 0, Grade 1, 2 or 3
Each grease has a "base material compound" .... There are aluminum complex, Lithium Complex, Parafinic, Synthetic, Semi-Synthetic and Petroleum based lubricants(greases & oils). The base compound does nothing for lubrication of metal, it is the additives in the grease or oil that provide the barrier material for metal protection and anti corrosion. The base compound is just the carrier agent for the true lubricants. There are many tests of greases & lubricants to see what metal protection they offer ... most notable is the "4 ball wear-scar test."
I have had some issues with NLGI grade 1 and 2 being too tacky on my 22lr & 45ACP slides. So in conclusion .... the grade of the grease actually tells nothing about it's lubrication, or metal protection characteristics, just how long it takes to be squeezed through a specific and equal orifice.
But in reality, most standard industrial lubricants offer more than enough protection for the needs of us in the consumer gun industry. I suggest you use something .... anything that keeps your gun functioning properly and doesn't get too dirty, or "carbon up" when fired a lot.
