Abstract

Multigrade oils comprise a mixture of (a) a de-waxed paraffin-based oil having a viscosity of less than 5 cs. at 100 DEG C., a viscosity index of over 90 and a solidification point below - 15 DEG C.; (b) naphthalene based oils having a viscosity above 5.6 cs. at 100 DEG C., a viscosity index between 45 and 65 and a solidification point below -35 DEG C.; and (c) one or more viscosity index improving agents, e.g. polyacrylic esters; the ratio of (a) : (b) being between 1:5 and 1:1. The composition may also contain up to 20% of diesters or olefine polymers.
