Lubricant Antioxidant Additives are chemicals that can improve the antioxidant properties of lubricating oil, (e.g. motor oil, grease) and extend its use or storage life.
The most common antioxidant additives are ph-enolic ester antioxidants and amine antioxidants. Examples include antioxidant ester ph-enol type T512 and butyl octyl diphenyl-amine T534. These high-temperature antioxidants work with other oil additives to increase the life and performance of your engine oil or industrial lubricants.
