  The present invention provides a lubricating oil composition which comprises in combination with a base oil: (A) a 3-methyl-5-tert-bubyl-4-hydroxyphenyl substituted fatty ester of the formula    where R1 is a C1-C6 alkylene group, and R2 is a C1-C24 alkyl or alkenyl group; (B) a N-p-alkylphenyl-α-naphthyl amine of the formula    where R3 is a C1-C6 alkyl group; and (C) a p,p'-dialkyldiphenyl amine of the formula where R4 and R5 each are a C1-C16 alkyl group. The various components (A)-(C) as combined with a mineral or synthetic base oil are surprisingly conducive to both oxidation stability and sludge inhibiting performance under elevated temperature conditions over extended periods of service life.
