Abstract: Full-range shale oils or fractions thereof, after hydrotreating, or hydrowaxed and then hydrogenated to produce lubricating oil fractions boiling above 650.degree. F., having a pour point at or below +10.degree. F., and a viscosity index of at least 95. In the preferred operation, the hydrogenation is effected with a noble metal-containing catalyst wherein the noble metal is dispersed by cation exchange into a carrier comprising a silica-alumina cogel or copolymer dispersed in a large pore alumina gel matrix. It has been found with shale oils that the hydrogenation in the preferred embodiment also results in hydrocracking of some of the polynaphthenic compounds.

Abstract: Full-range shale oils or fractions thereof, after hydrotreating, are hydrodewaxed and then hydrogenated to produce lubricating oil fractions boiling above 650.degree. F., having a pour point at or below +10.degree. F., and a viscosity index of at least 95.

Abstract: This invention provides novel lubricating oil compositions comprising an organometallic additive, including a metal selected from Groups I, Ib, and VIII of the Periodic System of Elements, e.g. Na, K, Cu, Co, Ni or Fe, chelated with the reaction product of formaldehyde, an amino acid and a phenol, dissolved in a lubricating oil. Depending on the choice of the metal, the above organometallic additive imparts rust inhibition, sludge dispersant, wear reduction and anti-oxidant properties to said lubricating oil compositions.

Abstract: This invention provides novel organometallic compositions represented by the general formula: ##STR1## wherein M is selected from the group consisting of members of Groups IIa, IIb, IIIa, IVa and VIIb of the Periodic System of Elements; R.sup.1 is selected from the group consisting of radicals represented by the formula ##STR2## wherein R.sup.2 is selected from the group consisting of hydrogen, hydrocarbyl radicals and heteroatom-substituted hydrocarbyl radicals wherein said heteroatoms are selected from the group consisting of halogen, oxygen, sulfur, nitrogen and phosphorus atoms; R.sup.3 is selected from the group consisting of hydrogen and lower alkyl radicals; R is selected from the group consisting of hydrocarbyl radicals and hetero atom-substituted derivatives thereof wherein said heteroatoms are selected from the group consisting of halogen, oxygen, sulfur, nitrogen and phosphorus atoms; and v, w, x, y and z are integers.
