Professionals and everyday drivers alike should get to know the most current engine oil performance standard: GF-6. Specifically, this standard is designed to meet the demands of modern engines and offers you a lot of benefits. Let's dive into what it is and why it matters.

What is GF-6?

GF-6 is the latest engine oil standard released by the International Lubricant Specification Advisory Committee (ILSAC). Thus, It is a big improvement over its predecessor, GF-5. Furthermore, it offers you a range of new benefits tailored to the demands of modern engine technology.

Why the Upgrade?

Car engines are changing, and GF-6 helps you keep up with these changes. In specific, key drivers for this new standard include:

  • Turbocharged Engines: The rise of smaller, turbocharged engines for greater fuel efficiency. These engines create unique lubrication demands.
  • Low-Speed Pre-Ignition (LSPI): Turbocharged engines can be susceptible to LSPI, a damaging premature ignition issue that GF-6 oils are formulated to prevent.
  • Fuel Economy: Stricter fuel economy standards necessitate engine oils that reduce friction and improve overall efficiency.
  • Emissions: Formulations optimized for compatibility with emission control systems.

Key Benefits of GF-6 Oils

Specifically, here's what you can expect from oils meeting the GF-6 standard:

  • Improved Fuel Economy: GF-6 oils contribute to overall fuel savings thanks to enhanced friction reduction properties.
  • LSPI Protection: Specially designed to combat the damaging effects of LSPI in turbocharged engines.
  • Timing Chain Wear Prevention: Protects against wear in timing chains, which are crucial components in modern engines.
  • Enhanced Engine Cleanliness: Prevents sludge buildup and keeps your engine cleaner over time.
  • Compatibility with Emission Systems: GF-6 oils work together with modern emission systems to reduce environmental impact.

GF-6A vs. GF-6B

GF-6 oils come in two subcategories:

  • GF-6A: Backward compatible with older standards. Suitable for SAE 0W-20, 5W-20, 0W-30, 5W-30, and 10W-30 viscosity grades.
  • GF-6B: Specifically designed for ultra-low viscosity SAE 0W-16 oils, often used in newer engines optimized for maximum fuel efficiency.

Finding GF-6 Oils

Look for the ILSAC starburst symbol on oil bottles for GF-6A oils, and a new shield-like symbol for GF-6B. You'll find these readily available at auto parts stores and from major oil brands.


In conclusion, GF-6 represents a leap forward in engine oil technology, offering enhanced protection and performance for modern engines.
