A viscosity index improver comprising a reaction product of (i) an acylated copolymer obtainable by acylating a copolymer of ethylene and one or more C3-C10 alpha-olefins having an Mn of 3,000 to 250,000 g/mol; and (ii) a compound of the formulae (I)-(V):
wherein R1, R6, R8, R9, R10, R12 and R15 are independently selected from a hydrogen and an optionally substituted linear or branched alkyl or alkenyl group, and R2, R3, R4, and R5 R7, R11, R13, R14, R16, and R17 are independent selected from an optionally substituted linear or branched alkyl or alkenyl group, and a sum of the number of carbon atoms in each compound of the formulae (I)-(V) is from 6 to 31.
