Liberty Oil is a 100% synthetic oil that comes in a 4-fluid-oz bottle with a stainless steel needle tip dispenser. Because it is premium quality 100% synthetic oil it easily outperforms all other oils on the market. This oil contains two friction modifiers that bond and protect the metal and act like tiny ball bearings to reduce friction and wear. The bottles are new using LDPE, which is a very soft plastic that is easy to squeeze. You will also receive a 1.5inch 18-gauge stainless steel needle tip that is of pharmaceutical grade with patented Luer lock cap to insure that you have no leaks from your bottle and cap. Liberty Oil is 100% synthetic and can be used anywhere there is a friction point. Examples are gears, bushings, bearings, sliding metal parts; plastics or it can be used to prevent corrosion of metal. It will not attract dirt and other contaminants that will damage any friction point. Once you use Liberty Oil you will discover the 100% synthetic difference.
