Abstract

A lubricating oil composition exhibiting improved low temperature flow properties and viscometric properties comprising lubricating oil and
  • (i) an amount effective to improve the low temperature flow properties of said lubrica­ ting oil composition of additive consisting essentially of at least one low molecular weight polymer or interpolymer of unsaturated carboxy ester represented by the formula wherein R′ is selected from the group consist­ ing of hydrogen and COOR, and R is a C₁₄ alkyl group; and
  • (ii) an amount effective to improve the viscosity index of said lubricating oil composition of additive comprising hydrocarbon polymeric viscosity index improver.
