Anything Auto Immune

Additives are supplements designed to extend the life of the oil and enhance its operating qualities. Major additives include:
1. Detergents. Remove grit and other contaminates from operating parts.
2. Foam Inhibitors. Limit the formation of bubbles (foam) created by rotation of the crankshaft and rods, which helps the oil pump work at maximum efficiency.
3. Oxidation Inhibitors. High engine temperatures can create acids that attack metal surfaces. These additives help the oil resist thickening and sludge formation.
4. Friction Modifiers. Reduce friction losses, which help improve fuel economy and power.
5. Anti-Wear Compounds. Help protect components under heavy load (such as the crankshaft rod and main bearings) from premature failure.
6. Corrosion Inhibitors. Reduce rust and wear damage created by acids and moisture.
7. Pour Point Depressants. Improve the ability of oil to flow at very low temperatures. (Used in so-called “winter oils.”)
8. Viscosity Index Improver. Helps stabilize the oil’s flow capabilities by assisting the oil’s natural tendency to fight changes of viscosity with temperature change.
