(US10808197) What is claimed: 1. A lubricating oil composition comprising   a) a lubricating oil, and   b) one or more alkylated alkoxydiarylamine of formula III: wherein x is 0, 1 or 2 and y is 1, 2 or 3;   R′ is C1-12 alkyl or C1-12 alkyl substituted by one or more hydroxyl or alkoxy;   each R is independently C4-24 alkyl, C7-18 aralkyl, or C4-24 alkyl substituted by one or more hydroxyl and/or interrupted by one or more oxygen atom;   wherein the total number of carbon atoms of the combined groups R is 12 or higher, and wherein at least one carbon atom adjacent to the amine nitrogen is unsubstituted. 2. The lubricating oil composition according to claim 1 wherein b) is present in an amount of about 0.1 to about 5.0 wt%, based on the weight of the lubricating oil composition. 3. The lubricating oil composition according to claim 1 wherein b) is present in an amount of greater than 5 wt%, up to about 50 wt%, based on the weight of the lubricating oil composition. 4. The lubricating oil composition according to claim 1 further comprising one or more alkylated diarylamine not substituted by an alkoxy group. 5. The lubricating oil composition according to claim 1 wherein in the alkylated alkoxydiarylamine of the formula III x is 0 or 1 and y is 1. 6. The lubricating oil composition according to claim 1 wherein the alkoxy group of the alkoxydiarylamine is at the 3-position relative to the nitrogen according to formula V: 7. The lubricating oil composition according to claim 1 wherein the total number of carbon atoms of the combined groups R is 16 or higher. 8. The lubricating oil composition according to claim 6 wherein in the alkylated alkoxydiarylamine of the formula V x is 0 or 1 and y is 1. 9. The lubricating oil composition according to claim 6 wherein in the alkylated alkoxydiarylamine of the formula V x is 1 and y is 1. 10. The lubricating oil composition according to claim 1, wherein the alkoxy group R′O is on the phenyl ring at the 2- or 3-position relative to the nitrogen atom. 11. The lubricating oil composition according to claim 1, wherein x is 1 and y is 1. 12. The lubricating oil composition according to claim 1, wherein both aryl groups in the formula III are alkylated. 13. The lubricating oil composition according to claim 1 wherein x is 0, y is 1, R′ is methyl or ethyl, and R is selected from dodecyl, octadecyl, and icosane. 14. The lubricating oil composition according to claim 1 wherein x is 1, y is 1, R′ is methyl or ethyl, and R is selected from hexyl, octyl, nonyl, decyl, and dodecyl. 15. The lubricating oil composition according to claim 1 wherein x is 1, y is 1, R′ is methyl or ethyl, and one R is n-butyl, sec-butyl, tert-butyl or hexyl and the other R is t-octyl, nonyl, dodecyl, hexadecyl or octadecyl. 16. The lubricating oil composition according to claim 1 wherein x is 1, y is 1, R′ is butyl or hexyl, and R is selected from n-butyl, sec-butyl, iso-amyl, hexyl, octyl, nonyl, and dodecyl. 17. The lubricating oil composition according to claim 1, wherein the lubricating oil comprises one or more hydrocarbon base stocks. 18. The lubricating oil composition according to claim 1 wherein x is 0 or 1 and y is 1 or 2. 19. The lubricating oil composition according to claim 1 wherein R′ is C1-12 alkyl. 20. The lubricating oil composition according to claim 1 wherein each R is independently C4-24 alkyl. 21. The lubricating oil composition according to claim 20 wherein R′ is C1-6. 22. The lubricating oil composition according to claim 21 wherein x is 0 or 1 and y is 1 or 2.
