ILSAC Engine Oil Specifications and Multigrade Synthetic Oils

The International Lubricants Standardization and Approval Committee (ILSAC) is an organization responsible for establishing standards for engine oils used in automobiles. These specifications are crucial in ensuring the quality and performance of motor oils, catering to the demands of modern engines and addressing industry trends.

Key Facts

  1. ILSAC (International Lubricants Standardization and Approval Committee) is an organization that sets standards for engine oils used in automobiles.
  2. ILSAC specifications are often indicated on motor oil bottles and may include designations such as GF-1, GF-2, GF-3, GF-4, GF-5, and GF-6.
  3. ILSAC GF-6A is a specification that is fully backward compatible with ILSAC GF-5, offering better fuel economy, improved engine protection, and enhanced performance while maintaining durability.
  4. ILSAC GF-6B is a specification that allows for lower viscosity oils like SAE 0W-16, which can provide fuel economy benefits. However, oils meeting the GF-6B standard are not backward-compatible unless specified by an OEM (Original Equipment Manufacturer).
  5. Synthetic motor oils can meet ILSAC specifications. For example, there are full synthetic motor oils available in the market that meet the ILSAC GF-6A specification.

ILSAC Specifications

ILSAC specifications are typically indicated on motor oil bottles and may include designations such as GF-1, GF-2, GF-3, GF-4, GF-5, and GF-6. Each specification represents a set of performance requirements that engine oils must meet to be considered compliant. These specifications are regularly updated to keep pace with technological advancements and evolving engine designs.

ILSAC GF-6A and GF-6B

ILSAC GF-6 is the latest specification for passenger car motor oils, introduced in 2020. It is divided into two sub-categories:

  • GF-6AThis specification is backward-compatible with previous ILSAC standards and covers SAE 0W-20, SAE 5W-20, SAE 0W-30, SAE 5W-30, and SAE 10W-30 viscosity grades. It offers improved fuel economy, enhanced engine protection, and better performance while maintaining durability.
  • GF-6BThis specification is specifically designed for SAE 0W-16 viscosity grade oils. It provides fuel economy benefits but is not backward-compatible unless specified by the Original Equipment Manufacturer (OEM). This distinction is clearly indicated on eligible motor oil labels.

Synthetic Motor Oils and ILSAC Specifications

Synthetic motor oils can meet ILSAC specifications, offering several advantages over conventional oils. They provide superior protection against wear and tear, improved resistance to oxidation and thermal breakdown, and better flow characteristics at low temperatures. Full synthetic motor oils are formulated using synthetic base stocks and additives, meeting the stringent requirements of ILSAC GF-6A and GF-6B specifications.

Conclusion

ILSAC specifications play a vital role in ensuring the quality and performance of engine oils. ILSAC GF-6A and GF-6B are the latest specifications, addressing the needs of modern engines and providing improved fuel economy, enhanced engine protection, and better performance. Synthetic motor oils can meet ILSAC specifications, offering superior protection and performance compared to conventional oils.
