Its 46 viscosity balances film strength and flow to maintain lubrication across typical operating temperatures, while built-in UV dye helps technicians spot leaks quickly. Additives such as anti-wear agents, friction modifiers, and antioxidants work together to reduce mechanical wear, limit deposit formation, and support OEM-level performance.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this oil improve compressor longevity?\u003c\/h3\u003e\n\u003cp\u003eThe P46 formulation contains anti-wear chemistry that forms a protective film on moving parts and friction modifiers that reduce internal drag.
