Lubricating oil is a base oil; and an anti-degradation additive comprising microcapsules, nanocapsules, or combinations comprising at least one of the foregoing; The microcapsules and nanocapsules each independently have a core of the neutralizing material and a polymeric encapsulant configured to release the neutralizing material in an acidic environment by breaking cross-links or hydrogen bonds in the polymeric encapsulant. The released neutralizing material prevents the formation of viscous high molecular weight molecules, so it can increase the life of the lubricant and improve its reliability. |
