ABSTRACT:
Fully synthetic lubricating base oil compositions are formulated from blends of 50-97 wt % of synthetic hydrocarbons and 3-50 wt % isobutylene oligomers. The lubricating base oil compositions have constant viscosity indexes which are higher than those of the components used to form the compositions. The synthetic hydrocarbon and isobutylene oligomers are combinable in various amounts with conventional additives to form multi-grade engine lubricants, which are shear stable.
