Provided is a composition including fluid carbon dioxide and a polyolefin thickener, wherein the polyolefin thickener includes a polymer of one or more olefin monomers having 8 or more carbon atoms, wherein at least 5 mol percent of the olefin monomers have 12 or more carbon atoms. Associated methods are also provided.

Carbon dioxide viscosification

A lubricating composition including an oil of lubricating viscosity and a benzazepine compound. Methods of using such lubricating compositions are also disclosed.

Benzazepine compounds as antioxidants for lubricant compositions

A composition including a major amount of carbon dioxide and at least one branched polyolefin polymer is described, as well as methods of making and using the composition, such as in increasing the viscosity of carbon dioxide for use in carbon sequestration and/or enhanced oil recovery.

Carbon dioxide viscosification by polyolefins

An additive for a lubricating composition includes an ionic tetrahedral borate compound which includes a cation and a tetrahedral borate anion having a boron atom, the boron atom has at least one aliphatic bidentate di-oxo ligand. The cation may be selected to provide detergent and/or dispersant and/or antioxidant properties to a lubricating composition.

Aliphatic tetrahedral borate compounds for lubricating compositions

A lubricating composition includes an oil of lubricating viscosity and a low-ash additive system including a low molecular weight amine with a Total Base Number of at least 150, and an N-substituted hydrocarbyl-substituted succinimide dispersant. The low-ash additive system provides the lubricating composition with a significant boost in TBN without substantially lowering the flashpoint. The composition is particularly suited to use as a marine diesel engine lubricant.

Total base number boosters for marine diesel engine lubricating compositions

A fully-formulating lubricating composition comprising an oil of lubricating viscosity; an ionic tetrahedral borate compound including a tetrahedral borate anion having a boron atom with two bidentate di-oxo ligands both being a linear C18-tartrimide; a first dispersant comprising a conventional ammonium substituted polyisobutenyl succinimide compound having a polyisobutenyl number average molecular weight of 750 to 2,500; a second dispersant comprising an ammonium substituted polyisobutenyl succinimde compound having an N:CO ratio of 1.8 and a polyisobutylenyl number average molecular weight of 750 to 2,500, wherein one or more of the first dispersant and the second dispersant are in cationic form. The fully formulated lubricating composition including one or more performance additives.
