poly bushing assembly lube

I use Super Lube.

Super Lube® is a patented, multi-purpose synthetic lubricant, containing SYNCOLON® (PTFE) particles held in suspension. Super Lube® lasts longer and outperforms conventional petroleum-based greases. Super Lube® Grease is an exceptionally pure lubricant, because it is synthetic. This gives Super Lube® very stable and predictable chemical properties.
