Oil Science

Synthetic, semi-synthetic, and mineral oils are three types of lubricants commonly used in various applications. These oils differ in their composition, properties, and performance.

Mineral Oil: Derived from crude oil after refining, it’s cost-effective and suitable for basic lubrication but has lower high-temperature stability, often used in older vehicles.

Semi-Synthetic Oil: A blend of mineral and synthetic oils that balances affordability and performance. It can extend drain intervals and reduce over all costs versus straight mineral oil.

Synthetic Oil: Engineered through chemical synthesis, it excels in high and low temperature stability, ideal for high-performance engines and demanding conditions.

In summary, the choice among synthetic, semisynthetic, and mineral oils depends on factors like application, budget, and performance requirements. Synthetic oils perform exceptionally well at higher engine temperatures, semi-synthetics offer a compromise, and mineral oils provide cost-effective lubrication for less demanding uses.
