Lubricant compositions having at least one base oil composition including about 1.0 to about 15.0 wt % water, and a friction-reducing composition including a glycerol or thioglycerol compositions are described. Methods for making such lubricant compositions and methods of drilling using such lubricant compositions are also described.

Lubricant compositions comprising diol functional groups and methods of making and using same

A lubricant compositions having at least one base oil composition and a friction-reducing composition including a substituted phosphate ester and/or substituted hydrogen phosphites are described. Methods for making such compounds and methods of drilling using such lubricant compositions are also described.

Lubricant compositions containing phosphates and/or phosphites and methods of making and using same

A lubricating oil including a lubricating oil base stock as a major component; and a mixture of (i) one or more protected lubricating oil additives having a first performance function, and (ii) one or more unprotected lubricating oil additives having a second performance function, as a minor component. The first performance function and the second performance function are the same. The one or more protected lubricating oil additives are inactive with respect to their performance function. The one or more protected lubricating oil additives are converted into one or more unprotected lubricating oil additives in the lubricating oil in-service in an engine or other mechanical component. A method for controlled release of one or more lubricating oil additives into a lubricating oil. A method for improving oxidative stability of a lubricating oil and extending performance life of one or more lubricating oil additives.

Lubricant compositions containing controlled release additives

A lubricating oil including a lubricating oil base stock as a major component, and one or more lubricating oil additives having at least one protected active group, as a minor component. The one or more lubricating oil additives having at least one protected active group are converted into one or more lubricating oil additives having at least one unprotected active group in the lubricating oil in-service in an engine or other mechanical component. Compositions including one or more lubricating oil additives having at least one protected active group. A method for improving solubility of one or more lubricating oil additives in a lubricating oil. A method for improving oxidative stability of a lubricating oil and extending performance life of one or more lubricating oil additives. A method for improving friction control in an engine or other mechanical component lubricated with a lubricating oil.
