I like a good grade 50 motor oil. Works well on my guns as well as in my Harley.

I use this on all my guns (SIg's included).

I have both the lite and medium weights (lite for the .22) and medium for everything else. Works great and stays in place. If you look at http://www.sigforum.com or other related sites you'll see a pretty big following for the stuff.

I've been using Mobil 1 for many years, upon the recommendation of a very experienced police armorer, and have been well pleased with it.
