The main lubrication components are listed on the package and the greases rating is too....often the name of the grease blend is the give away so as not to need to read the fine print.Not mentioned and not particularly relevant but one mandatory requirement for
synthetic grease is when your equipment operates at temps below when regular
grease freezes solid. There are various greases with different and incompatible
base formulas such as lithium but I forget what their special applications are.
I do know that when they are mixed they can disolve each other and you get
close to zero lubrication so it is worth paying attention to. I think a lot of brands
rely on that to scare you into only using their brand by not telling you if they
are or are not compatable with other brands and by not telling you their main
components.
