Came across this grease type compatibility chart and thought it might be useful for some of us, maybe moreso for 4-wheel applications, than bikes.

Good to copy off and keep in your garage "reference" notebook.
Also, there's a somewhat informative discussion about moly-based versus lithium based on the Toyota Tundra forum:

Hmm, the Tundra link doesn't work. Try a search for Mobil 1 grease on their site.

The "additives" post got me going last night. No substitute for good maintenance; 2-wheel OR 4-wheel. Plenty of examples on this site.
FWIW.
