Understanding Base Oils

一月 26, 2026

For Avtoil, effective lubrication starts with the correct choice of base oil. As the main constituent of any lubricant, base oil determines the product’s fundamental performance characteristics.

Base oils influence wear protection, temperature behavior, oil ageing, and compatibility with modern engine and emission system requirements. Mineral base oils are refined from crude oil to varying degrees, while synthetic base oils are chemically produced to deliver higher purity, better thermal stability, and longer service intervals.

By following the API base oil classification system and carefully matching base oil groups to application needs, Avtoil formulations achieve a balance between performance, reliability, and efficiency. The result is lubricants that provide stable operation, reduced friction, and dependable protection across a wide range of automotive applications.

Avtoil formulations are built around robust and proven mineral base oils, complemented by upgraded technologies where required.

• Group I base oils are utilized for traditional engines and standard service intervals.
• Group II base oils enhance performance through improved purity, better oxidation control, and cleaner engine operation.
• Selected Group III base oils are applied in upgraded products to meet the needs of newer vehicles and tougher operating conditions.
