Declarations under Rule 4.17: as to applicant's entitlement to apply for and be granted a patent (Rule 4.17(ii)) as to the applicant's entitlement to claim the priority of the earlier application (Rule 4.17(iii)) Published: — with international search report (Art. 21(3)) before the expiration of the time limit for amending the claims and to be republished in the event of receipt of amendments (Rule 48.2(h)) W O 20 18/ 18755 8 Al (54) Title: ANTI-DEGRADATION AND SELF-HEALING LUBRICATING OIL (57) : A lubricating oil comprises a base oil; and an anti-degradation additive comprising microcapsules, nanocapsules, or a combination comprising at least one of the 100 foregoing; the microcapsules and the nanocapsules each independently having a core of a neutralizing material and a polymeric encapsulant configured to release the neutraliz- ing 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. 12 FIG. 1 15
