Lucas Oil Fishing Reel Oil is a special blend of oil and additives specifically designed to lubricate all moving parts in fresh and saltwater fishing reels. It penetrates into tight spaces to lubricate small high speed bearings and in between tight surfaces. It provides rust and corrosion protection, even under the most adverse conditions. Also works great on folding knives. Oil comes packaged in a 1-oz. bottle with a precision needle applicator for one-drop applications so you can put just the right amount of lubricant into hard to reach areas.
