Used and recommended by major firearms manufacturers, Lucas Extreme Duty Gun Grease is a premium, heavy duty firearm grease formulated with a unique additive system designed to provide maximum lubrication under the most severe operating conditions.

This is true firearms grease, it was developed to lubricate and protect under the harshest heat, friction and pressures of sustained firing while reducing friction and wear. Its unique formulation is designed to prevent rust and corrosion from rain and moisture in fresh and saltwater environments.

SHOT Show 2016 Lucas Oil

Bryce Curry of Lucas Oil talks about the extensive line of oil and cleaning products now available for firearms. Bryce breaks down the uses of the new products.

The old saying, "oil is oil is oil, is so far from the truth.

I was showing my wife 3 gun competitions and the topic of Lucas Oil came up. It is quite nice to see you involved in the firearms community as well as my favorite hot rod. In the case of the Hot Rod my favorite was a One Ton 4X4 with a 500hp big block in it. Needless to say it was quite a beast which I finally sold after 28 years of rumbling around. Your Octane Booster is one of my favorites for my tuned Tahoe which allows me to push it without worrying about a fuel fail. As for the firearms world I am a retired Sniper so working precision tolerances is a normal day for me. I often end up explaining the concept of film strength, thermal stability, friction modifiers, and of course Large Molecule Long Chain Synthetics to my associates as I choose my lubricants carefully. The old saying, "oil is oil is oil, is so far from the truth. When I was sitting in a Sniper position covering my coworkers against an active shooter in a 37deg rain those lubricants protected my equipment and thus my team. I am not allowed to make a mistake and my equipment must work or we die. My compliments to all of you at Lucas Oil. Keep doing what you do best keeping all my precision machines running at peak performance with unyielding reliability. David J. Szibel Deputy Sheriff-Retired: S.W.A.T.
