I've used/checked out a LOT of lubricants over the years. There are some great lubes at great (Read: EXPENSIVE) cost out there. I need a high volume of good lube cheap (At least 3 quarts in reserve). I've tried fully synthetic motor oils(Internal combustion engine additives that are unwanted), auto trans fluid (More additives, plus the smell), and other concoctions. I want a PTFE (Teflon) lube that has great film strength, good adhesion for a liquid, and performance over a wide temp range.
Here is what I've come up with:
9 ozs. of Mobil1- 75W90 full synthetic rear end lube mixed with 7 ozs. LSA Mil/spec semi fluid lubricant.
It has great flowing properties, film strength, lubricity, and it flows at -5degrees F (The lowest my freezer will go). There is VERY little separation over long periods of time. Most PTFE products separate out in a very short time.
I have used this concoction for several years across a broad spectrum of guns- revolvers, metal automatics, composite autos, bolt guns, Garands, M1As, and the AR15 series.
For grease I use:
8 ozs. Mobil1 full synthetic gear grease (The red stuff) mixed with 7 ozs. of the same LSA PTFE semi fluid. This makes a light grease that can be used on all sliding parts. It has a great drop temp and adhesive properties.
Any opinions? Anyone want to try it?
