EngIne OIl AddItIves
Antioxidant
It provides oxidation resistance. Antioxidants help slow oxidation in the oil to help keep engines running clean.
Viscosity Index Improvers
Sets the rate of change of viscosity between 2 different temperatures.
PAO
It has high performances of Durability, Low Temperature Characteristics (Cow Point and Viscosity), Low Volatility, Thermal Stability.
MEG
It is used as antifreeze.
PEG 400
It is used to prevent the polymer chain from unraveling.
Defoamer
It minimizes the possibility of small bubbles being trapped in the fuel or oil. It is also used to zoom out.
Anti-Abrasion/Anti-Corrosion
Zinc dithiophosphates used in motor oils are multi-purpose additives such as oxidation inhibitor, anti-wear and bearing corrosion inhibitor.
DEG
It is a colorless, practically odorless, and hygroscopic liquid with a sweetish taste. It is a four carbon dimer of ethylene glycol. It is miscible in water, alcohol, ether, acetone, and ethylene glycol.[1] DEG is a widely used solvent.
