This disclosure describes low ash lubricating composition achieving passing steel corrosion, passing high temperature deposit formation, and emulsion stability. The lubricating compositions include one or more select corrosion or rust inhibitor chemistries having an oil-soluble acyclic structure with acidic, hydroxy, or amine moieties but being free of imine, imide, and/or amidine moieties.
