A process for preparing a low ash detergent, the process comprising:
- mixing a surfactant composition that includes hydroxybenzoate, sulfonate, or phosphonate detergent with an ashless nitrogen-containing compound to boost the base number of the hydroxybenzoate, sulfonate or phosphonate detergent.
A process for preparing a low ash detergent, the process comprising:
- mixing hydroxybenzoate, sulfonate, or phosphonate detergent with an amine or amine derivative, wherein the amine or amine derivative is added to overbase or boost the base number of the hydroxybenzoate, sulfonate or phosphonate detergent.
A lubricating oil composition comprising:
- major amount of an oil of lubricating viscosity;
- and
- minor amount of a low ash detergent made from a process comprising:
- mixing hydroxybenzoate, sulfonate, or phosphonate detergent with an amine or amine derivative, wherein the amine or amine derivative is added to overbase or boost the base number of the hydroxybenzoate, sulfonate or phosphonate detergent.
