I called RnR and asked them what the cloudy stuff is at the bottom was, and what kind of lube the use--synthetic or mineral based. They said the solid is teflon (PTFE) and their lube is synthetic based with a solvent. Exact perportions and what they use I did not ask, but the stuff I now use shure works alot like theirs.

If you are not keeping up with 6 kids and 10 bikes, you will get a bottle of RnR gold to last a long time and probably isn't worth it to you to make your own.

BTW, I also strip clean the chain every 500-600 miles with a park tool chain cleaner that I run the chain backwards through 3 roller brushes and is filled with degreaser and mineral oil. I then wash the chain off with a mist spray of water, let dry, wipe clean, then lube. I am kind of a clean chain nut. Nothing like a smoothe quet chain
