Huh? . . . Wha? . . . Why? . . .

I'll give you the benefit of the doubt that this isn't a troll and you are genuinely interested in making your own grease. The first big question is "Why?". There are numerous greases on the market that will do the job and I can't imagine any homemade concoction that would be any better. Park Grease, SuperLube, and many other better greases run $12-$15 per pound can (enough to service several bicycles for years). Many general purpose greases can be had at any big box, automotive, hardware or home improvement store for as little as $5 a pound.

Even at $6 a 4oz tube, Park grease would cost you about $1 per year, per bike if you did full servicings including BB and headset (most of which are sealed bearings on newer bikes).
