Choose Your Engine Oil Additives Help Topic Below
So, Engine oil additives are chemical compounds. They improve the lubricant performance of a base oil. As a result, nearly all oils contain additives. Whether the oils are synthetic or petroleum based.
Engine oil additives have three basic roles:
- Enhance existing base oil properties.
- Suppress undesirable base oil properties.
- Impart new properties to base oils.
The most important engine oil additives:
So, The best engine oil additives are oil stabilizers and viscosity modifiers. Because, they help the oil last longer. As a result, they improve or extend the oil’s extreme pressure protection.
So, engine oil additives reduce engine wear and increase fuel efficiency.
Viscosity is the most important property of a base oil. However, there is more to lubricants than just viscosity.
Other Important Information About additives:
So, More additive is not always better. The old saying, “If a little bit of something is good; then more of the same is better”. But, This is not necessarily true when using oil additives. So, Increasing the percentage of a certain additive; may improve one property of an oil. While, at the same time degrade another. When the specified concentrations of additives; become unbalanced; overall oil quality can be affected.
Some additives compete with each other; for the same space on a metal surface.
So; the longer the oil remains in service; the less effective the remaining additive is.
When the additive weakens:
- Viscosity increases
- Sludge begins to form
- Corrosive acids start to attack bearings.
Basic Functions Of Additives:
- Reduce friction and wear and prevent scoring and seizure.
Corrosion & Rust Inhibitors
- Prevent corrosion and rusting of metal parts.
- Keep surfaces free of deposits and neutralize corrosive acids.
- Keep insoluble soot dispersed in the lubricant.
- Alter coefficient of friction.
- Reduce the rate of viscosity change with temperature.
- Prevent lubricant from forming a persistent foam.
- Retard oxidative decomposition.
- Reduce catalytic effect of metals.
So, there is a lot of chemistry occurring in most engine oils. Consequently, mixing of different oils and adding additional lubricant additives should be avoided.
So, There are hundreds of chemical additives available.
However, some manufacturers will make claims that are exaggerated. As a result, they fail to mention a negative side effect.
So, Take great care in the selection of these products. Finally, If you want a better oil, buy a better oil.
