On August 16, 2022, ILSAC submitted a formal request for an updated engine oil specification to the API Lubricants Group and the Automotive Oil Advisory Panel (AOAP).

Replacing its predecessor, GF-6, the new category will aim to help original equipment manufacturers (OEMs) meet increasingly strict fuel economy targets expected to be enforced in the near future. This includes the Environmental Protection Agency’s (EPA) proposed Multi-Pollutant Emissions Standards for Model Year 2027.

Another key driver of the category update is to build on the protection offered by GF-6 against the occurrence known as LSPI. GF-7 will focus, in particular, on protection against LSPI not just for fresh oil after an oil change but also for aging oil to confirm it is still protecting the engine throughout the entire oil usage interval. For more information on LSPI, please see our other article on the topic Article: How is low-speed pre-ignition (LSPI) effecting the development of ISLAC GF-7.

Originally proposed to be introduced in 2028, it was decided to advance the introduction of ILSAC GF-7 to bring earlier value to the automotive sector, and act as a stepping stone between the requirements of GF-6 and the major category updates expected to come with the development of GF-8 (2028).

First available use of GF-7 licensed products will be March 31, 2025.

As with the introduction of GF-6 in May 2020, there will be a 12-month crossover period when GF-7 comes into licensing, where both GF-6 and GF-7 will be available. During this period customers can overturn inventory of the previous category in preparation to transition to GF-7. Once this 12-month period is over, GF-6 will become obsolete.

ILSAC GF-7 will build upon the benefits already offered by GF-6, providing improved performance, fuel economy, and greater oxidation and piston deposit control. As previously outlined, a key driver in the development of GF-7 will be further improving protection against LSPI, particularly in aged oil during oil drain periods.

Other benefits will include enhanced timing chain wear protection, seal compatibility, oil gelation and added protection for hybrid engines.

Now that ILSAC GF-7 is  finalized, we will continue on the groundwork that was undertaken in preparation for GF-6, which will help us pave the way for a seamless transition for our customers.

We are continuing to work with our industry partners and colleagues to make sure we hit the ground running when the category comes into licensing in March 2025.

For customers, the shift from ILSAC GF-6 to GF-7 will be seamless, with noticeable differences likely only detectable by mechanics over extended periods of use.

It's crucial to consult with both your OEM and your lubricant technical service advisor before making any changes to your lubricants and greases. Our experts can provide industry insight on the development of the GF-7 specification as well as tailored advice on what you should be doing to prepare.
