Keep in mind what any grease is...a thickener base which might be lithium complex or aluminum complex or something else. The characteristics of each base are well known. And an oil, whether conventional or synthetic or a blend. And additives such as moly, graphite, Teflon, tackifiers, dye, etc.
Amsoil makes good stuff, but look at all the characteristics of any brand of grease to see if it meets your needs.
