Abstract:
The invention relates to lubricating compositions, processes of making such lubricating compositions, and method of using such lubricating compositions. The lubricating compositions of the present invention include a dispersant comprising a quaternary ammonium salt, a phosphorus-containing compound, a metal dialkyldithiophosphate, a derivative of a hydroxyl carbonyl compound and an amine and/or an alcohol. These compositions provide balanced deposit control and wear performance without causing any seal compatibility issues.
