What’s special about the Upcoming GF-7 spec?

[FTTSHO]

I haven’t been keeping up with ILSAC GF-7 SQ at all. I just read a post saying it’s coming next month on the 31st. I just heard about it few minutes ago.

What differentiates the GF7 from GF6? I just feel like GF6 SP came out very recently, and it was supposed to be really good, and GF7 is coming out soon, and it’s obviously supposed to be even better than gf6.

What’s special about GF-7 SQ?

IIRC: All the major oils were meeting it for at least 6months now.

this post from december 2022 has some info

BITOG Pennzoil/API Forum Q&A – Questions

​

Q - ILSAC GF-7 will apparently be here in ~ 2028. 0W12 & 0W8 will now be included. Sustaining backward compatibility is also a stated goal. Are there any general comments you might have about future basestocks and add packs?

A - API RESPONSE: ILSAC GF-7 includes two new, low viscosity grade engine oils, SAE 0W-8 and SAE 0W-12. Engines must be designed to effectively use these low viscosity grade engine oils. As a result, their application will be limited to new engine designs from Automotive OEMs. Today, there are few engines...

To answer your question IMO: nothing is "groundbreaking" special. Its just a refinement of the min specs.. of which almost all major brand syn oils already far exceed.
and some new tests.

Will ILSAC GF-7 Introduce New Testing Requirements?​

While many of the existing tests from the GF-6 specification will carry over, some will be revised or replaced to ensure improved engine performance and durability. Key updates include:

• Enhancements to the Sequence IX Engine Test: Originally designed to evaluate LSPI performance, the Sequence IX test will now include an assessment of used oil to verify protection throughout the full oil drain interval.
• Stricter Fuel Economy Testing: The fuel economy testing requirements will be adjusted, with an expected 10% increase for SAE XW-20 and SAE 0W-30 grade oils and approximately a 5% increase for SAE 0W-16 grade oils.
• Potential Introduction of an Oil Gelation Test: A new test is being considered to address oil gelation issues that may arise during vehicle storage.
• Expanded Elastomer Compatibility Testing: Additional testing will be introduced to ensure compatibility with modern engine materials and seals.
• Sulphated Ash Limit Implementation: A limit on sulphated ash content will be added to help reduce engine deposits and emissions.
• Lower MRV Limits for Improved Pumpability: The new standards will include a reduced MRV (mini-rotary viscometer) limit to enhance oil pumpability in cold temperatures.

Some improvements.

Studing the graph from Chevron Oronite help me understand it better.

GF-7 will revitalize the excitement about the release of GF-8 - will they ever focus on Wear?

It says they're planning on reducing wear with the next revision but we'll have to wait and see.

the focus on fuel economy is here and going nowhere.
but is wear really an issue overall.. besides component such as timing chain etc.

Just to give you an idea of how some oils have been far ahead in piston deposit control:

GF-7 baseline is 4.6, up from 4.2 (GF-6).

I like when a company shows how much it exceeds standards. Wish it was more wide spread.

GM Is not gonna be Satisfied with the GF-7 specs so expect a Dexos 1 Gen 4 spec in the near future.

What’s special about GF-7 SQ?

Not much really.

 

[Emad]

When will this oil be available in the market like Amazon?

 

[Zee09]

When a manufacturer consistently builds a poorly engineered and machined engine no oil is going to resolve that issue.

 

[JohnnyJohnson]

The real difference probably around $2 to $4 a jug!

Using my last jug of GF-5 now … I need to speed up
