Lube oils of improved properties contain ethylene-propylene copolymer bearing moieties derived from the reaction product of allyl glycidyl ether and a heterocyclic amine such as N-(3-aminopropyl) morpholine.

Lubricating oil containing dispersant viscosity index improver

Fuel oils and lubricants of improved properties contain ethylene-propylene copolymers bearing units derived from N-vinyl pyrrolidone and phenothiazine.

Hydrocarbon compositions containing polyolefin graft polymers

Lubricating oils of improved oxidative stability, dispersancy, and viscosity index contain ethylene-propylene copolymer bearing allyl glycidyl ether or glycidyl methacrylate graft monomer--which has been functionalized with 2,5-dimethyl aniline or 2,6-dimethyl morpholine.

Multifunctional viscosity index improver

An oil containing a viscosity index improver of improved oxidative stability contains, as an anti-oxidant system 2,6-di-t-butylphenol and 1-3-aminopropyl-2-pipecoline.
