Today's Tip: Grease Selection Advice

To improve the reliability of grease-lubricated couplings, use only greases 
formulated for that purpose. General-purpose greases often have thickeners 
that are heavier than the oil. When subjected to the continuous and extreme 
forces of a spinning coupling, the thickeners in general-purpose greases can 
centrifuge to the outside, leaving the oil on the inside. Unfortunately, the 
outside is where the oil is needed. The thickeners in coupling greases are 
equal in weight to or lighter than the oil, ensuring that the wearing parts 
in the coupling are well lubricated.

=====================

Wonder if such grease would help driveshaft universal joints last longer than 
if ordinary chassis grease is used? Of course the most important thing is to 
grease them regularly (that is, if they have grease fittings (zerks) or removable 
plugs where the zerks can be screwed in temporarily)!
