Motor oil has changed, and the industry has officially moved from ILSAC GF-6 to the new GF-7 standard which launched on March 31, 2025. In this video we break down what GF-7 means, why it matters, and how the new testing requirements are designed to better protect modern engines. We cover the four major areas where GF-7 raises the bar: Low Speed Pre-Ignition, piston deposits, timing chain wear, and fuel economy.

You will learn what each problem is, how the tests work, and what specifically changed from GF-6 to GF-7, including why used oil is now part of LSPI testing and how that impacts real world engine protection.

If you want to understand what the GF-7 label on a bottle of oil actually tells you and why it is important for today’s engines, this video walks you through everything you need to know.
