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 to and protect the metal, acting like tiny ball bearings to reduce friction and wear. The bottles are newly made of LDPE, which is a very soft plastic that is easy to squeeze. You will also receive a 1.5-inch 18-gauge stainless steel needle tip that is of pharmaceutical grade with a patented Luer lock cap to ensure that you have no leaks from your bottle and cap.
