Abstract
A lubricating oil comprises a base oil; and an anti-degradation additive comprising microcapsules, nanocapsules, or a combination comprising at least one of the foregoing; the microcapsules and the nanocapsules each independently having a core of a neutralizing material and a polymeric encapsulant configured to release the neutralizing material in an acidic environment by breaking crosslinks or hydrogen bonds in the polymeric encapsulant. The released neutralizing material can prevent the formation of viscous, high molecular weight molecules thus enhancing the lifetime of the lubricating oil and improving its reliability.
