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.
