Abstract: Oil based compositions are disclosed which are comprised of oil having a multi-functional additive component therein. The additive component is present in sufficient amounts so as to provide improved performance characteristics to the composition such as water tolerance and antiwear characteristics. The additive is a compound represented by the general structural formula (I): ##STR1## wherein R is a hydrocarbyl, preferably iso-stearyl, R.sub.1, R.sub.2, and R.sub.3 are independently hydrogen or alkyl, preferably hydrogen, n is 1 to 20, preferably 5, and X is a cation, preferably Ca. Overbased and mixed salts of the additive compound are also disclosed. The additive is an effective EP agent, water tolerance fix in a variety of functional fluids and lubricating compositions.

Abstract: Oil based compositions including crank case oils and in particular diesel engine crank case oils are disclosed which are comprised of oil having a multi-functional additive component therein. The additive component is present in sufficient amounts so as to provide improved performance characteristics to the composition such as pH stability, water tolerance and antiwear characteristics. The additive is an overbased salt of a compound represented by the general structural formula (I): ##STR1## wherein R is a hydrocarbyl, preferably iso-stearyl, R.sub.1, R.sub.2, and R.sub.3 are independently hydrogen or aklyl, preferably hydrogen and n is 1 to 20, preferably 1 to 5. Statistical mixtures and mixed salts of the additive compound are also disclosed as are fully formulated oils. The additive is an effective pH stabilizer, EP agent, and water tolerance fix in a variety of functional fluids and lubricating compositions such as crank case oils, particularly diesel engine crank case oils.
