An environmentally-improved motor oil blend and related methods for properly lubricating components of an engine and favorably modifying a plastic response of components of the engine, the blend being free of zinc di-alkyl-di-thiophosphates (ZDDP) and free of zinc di-thiophosphate (ZDTP), comprising: a motor oil selected from the motor oil group consisting of Group I, Group II, Group III, Group IV, and Group V motor oils; a motor oil additive comprising alpha-olefins and hydroisomerized hydro-treated severe hydrocracked base oil; ZDDP omitted from the chemical constituents of the motor oil; and ZDTP omitted from the chemical constituents of the motor oil.

Methods for making alpha olefin oligomers and polyalphaolefins include a step of contacting a C.sub.4 to C.sub.20 alpha olefin monomer and a catalyst system containing a metallocene, a first activator comprising a solid oxide chemically-treated with an electron withdrawing anion, and a second activator comprising an organoaluminum compound. The alpha olefin oligomers and polyalphaolefins prepared with these catalyst systems can have a high viscosity index combined with a low pour point, making them particularly useful in lubricant compositions and as viscosity modifiers.

This invention relates to malienated derivatives made from maleic anhydride, functionalized monomers, and one or more additional reagents, e.g., an oxygen-containing reagent (e.g., alcohol, polyol), a nitrogen-containing reagent (e.g., amine, polyamine, aminoalcohol), a metal and/or a metal compound. The invention relates to lubricants, functional fluids, fuels, dispersants, detergents and functional compositions (e.g., cleaning solutions, food compositions, etc.)
