Abstract:
A composition of an oil-soluble ionic detergent that does not contribute metal ions to the composition, and which comprises a quaternary non-metallic pnictogen cation and an organic anion having at least one hydrocarbyl group of sufficient length to impart oil solubility to the detergent, the detergent having a total base number (TBN) to total acid number (TAN) ratio of at least 2:1 imparts ash-free basicity to a lubricant composition.
