Brief Overview
Lubricants are formulated with mineral oils and synthetic base oils and variety of additives to manufacture the desired lubricant. Depending upon the application and tribological regimes large number of lubricants are being formulated which can be broadly classified into three categories automotive, industrial lubricants and specialty oils. The lubricants further can be classified into various types such as engine oils, gear/ transmission oils, metal working fluids (neat and water soluble/miscible type), metal treatment fluids, rust preventive oils and specialty oils such as transformer oils, heat treatment oils and process oils. Most of the automotive lubricants are formulated based on bench/rig tests with the validated additive packages and selected base oils for manufacturing the lubricants and read across guidelines for interchangeability of base oils. However, during the manufacture, variety of physico-chemical and performance tests conducted to ensure the safety, quality of the product at various stages of manufacturing before releasing to market. Identifying the critical to quality parameters depending upon the lubricant and to ensure the compatibility and miscibility of lubricants is the key to supply quality products
