Abstract
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.
Claims20
A method of producing a motor oil blend, the method comprising:
- obtaining a motor oil that is configured to lubricate engines that include loaded steel-on-steel sliding mechanisms and/or non-babbitt bearings, and is void of zinc di-alkyl-di-thiophosphates (ZDDP) and void of zinc di-thiophosphate (ZDTP) as chemical constituents thereof;
- obtaining a motor oil additive comprising alpha-olefins and hydroisomerized hydro-treated severe hydrocracked base oil;
- omitting ZDDP from the chemical constituents of said motor oil additive such that the motor oil additive is void of ZDDP;
- omitting ZDTP from the chemical constituents of said motor oil additive such that the motor oil additive is void of ZDTP;
- combining said motor oil additive and said motor oil to form a motor oil blend that contains no ZDDP and no ZDDP yet provides lubrication of at least the sliding mechanisms and bearings of such engines and modifies a plastic response of at least a portion of the sliding mechanisms and bearings of such engines sufficient to achieve tribologically-measurable antiwear performance at least as good as that of the motor oil blend for such engines comprising at least one of ZDDP and ZDTP.
A method for lubricating an engine that includes loaded steel-on-steel sliding mechanisms and/or non-babbitt bearings, the method comprising:
- combining a motor oil configured for the engine and a motor oil additive to form a motor oil blend, said motor oil being void of ZDDP from its chemical constituents, said motor oil being void of ZDTP from its chemical constituents, said motor oil additive comprising polymerized alpha-olefins and hydroisomerized hydro-treated severe hydrocracked base oil, said motor oil additive being void of ZDDP from its chemical constituents, and said motor oil additive being void of ZDTP from its chemical constituents;
- introducing said motor oil blend that is void of ZDDP and ZDTP into the engine to lubricate at least one of the sliding mechanisms and bearings of the engine and modify a plastic response of at least a portion of the sliding mechanisms and bearings of the engine sufficient to achieve tribologically-measurable antiwear performance at least as good as that of the motor oil blend for such engines comprising at least one of ZDDP and ZDTP, and
- wherein introducing said motor oil blend into the engine, comprises lubricating the engine to a tribologically-measurable antiwear performance that is at least as good as that of the motor oil blend comprising at least one of ZDDP and ZDTP while preventing the release of environmentally-harmful ZDDP or ZDTP into the environment from the engine.
A method of producing a motor oil blend configured to lubricate an engine, comprising:
- configuring a motor oil to lubricate steel-to-steel contacting components and/or or between bearing and steel surfaces of the engine, said configuring comprising:
- obtaining a Group I, Group II, Group III, Group IV, or Group V motor oil;
- preventing ZDDP from being a chemical constituent of the motor oil such that the motor oil additive is void of ZDDP;
- preventing ZDTP from being a chemical constituent of the motor oil such that the motor oil is void of ZDTP;
- obtaining a motor oil additive comprising alpha-olefins and a hydroisomerized hydro-treated severe hydrocracked base oil;
- preventing ZDDP from being a chemical constituent of the motor oil additive such that the motor oil additive is void of ZDDP;
- preventing ZDTP from being a chemical constituent of the motor oil additive such that the motor oil additive is void of ZDTP;
- and
- combining an amount of said motor oil and an amount of said motor oil additive to form a motor oil blend that is void of ZDDP and ZDDP and is configured to provide lubrication of the engine and favorably modify a plastic response and to influence a chemical reactivity of the surfaces of the steel-to-steel contacting components and/or the bearing and steel surfaces of the engine that inhibits wear between said steel-to-steel contacting components and/or the bearing and steel surfaces to at least the same level than motor oil compositions for such an engine that comprises at least one of ZDDP and ZDTP while preventing the release of ZDDP or ZDTP from the engine during use thereof.
