The present disclosure provides a method for preparing a sulfurized alkyl phenate product to achieve a high sulfurization ratio of sulfurized alkyl phenate to unsulfurized alkyl phenate/phenol in the context of a neutralized and optionally overbased additive. The sulfurized alkyl phenate product is obtained by sulfurizing an alkyl phenol with a sulfur chloride blend that includes about 40 to about 75 weight percent of sulfur dichloride.

The disclosed technology relates to a lubricating composition comprising an oil of lubricating viscosity and an ashless basic amine additive selected from a secondary amine containing -carbon aromatic substitution. The basic secondary amine additives used in the lubricating oils of the disclosed technology impart basicity measured as total base number (TBN) without adding sulfated ash. Lubricating oils containing the basic secondary amine additives of the disclosed technology simultaneously achieve seals compatibility, deposit, and corrosion control.
