I have been testing several which include Terta oil and grease, Break Free, FP-10, Hoppes oil, Butches Gun Oil, and TW25B oil and grease. So far the Tetra oil and grease are the slickest followed by Hoppes in 2nd Break Free and FP-10 tied for 3rd Butches Gun Oil in 4th and TW25B in 5th.
The way I tested slickness (which is totally unscientific) was applying the oils to flat painted metal surface and rub them together till the paint started to wear. I aslo did the "between the fingers" test and I could get my finger and thumb to "studder" across each other by pressing as hard as I could. The Tetra oil was the only oil that I could not get my fingers to "studder" no matter how hard I tried. I also had other people do this with out knowing the lube and they to me he same results I found. so for slickness as far as my unscientific test could tell the best lubes were
1, Tetra
2, Hoppes
3, FP-10, Break Free tied
4, Butches gun oil
5, TW25B oil
I'm going to do a rust test this week to see how weel these prevent rust.
Which oils and lubes do you like and why? Thanks!
