Lubricants topics include: Lubricants selection and classification, additives types, lubrication mechanism, viscosity and viscosity index, neutralization number, saponification value, cloud and pour point, oxidation stability and aniline number. Lubricant chemistry is a specialized subset of organic chemistry, which is the study of carbon-based compounds and their reactions. Lubricant base oils are primarily hydrocarbons and are classified as organic compounds.  Here are some other topics related to lubricant chemistry: Base oils: The main raw material for all lubricant products.
