Liberty Oil is a 100% synthetic oil that comes in a 1-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 3cm 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. Do not use any other oil to lubricate your Stuff again!!!
