A lubricating oil composition formulated with a viscosity index (VI) improver composition including a combination of an ethylene α-olefin copolymer having no greater than 66 mass % of units derived from ethylene, and a linear diblock copolymer including at least one block derived primarily from a vinyl aromatic hydrocarbon monomer, and at least one block derived primarily from diene monomer.

A modified zeolite catalyst composition useful for the conversion of aromatic compounds to dialkylbenzene compounds rich in the 1,4-dialkylbenzene compounds rich in the 1,4-dialkylbenzene isomer. The reaction is carried out in the presence of a zeolite catalyst having a silica to alumina mole ratio of at least 12 and a constraint index of about 1-12, said catalyst having been modified by treatment with compounds of Group IV A (Ti, Zr, Hf), and optionally phosphorus, to deposit a minor proportion of such elements on the zeolite.

A modified zeolite composition useful for the conversion of aromatic compounds to dialkylbenzene compounds rich in the 1,4-dialkylbenzene isomer. The reaction is carried out in the presence of zeolite catalyst having a silica to alumina mole ratio of at least 12 and a constraint index of about 1-12, said catalyst having been modified prior to use by treatment with compounds of germanium, tin and/or lead, and optionally phosphorus, the deposit a minor proportion of such elements on the zeolite.
