MEETING THE API GF-6 SPEC TODAY!
Starting today, motor oil manufacturers and blenders are required to move Automotive fluids to the long-awaited GF-6 specification!
The new GF-6 specification has a brand-new set of stringent engine tests to go with a brand-new group of modern engines.
For the first time in the Automotive category, GF-6 splits the specification into two categories:
1. GF-6A - Grades with viscosities 0W-20 and greater
2. GF-6B - Grades with viscosities lower than 0W-20 (Grade 0W-16)
The transition to GF-6 brings a new API “SP” spec, which replaces the transitional API SN+.
This means that the GF-5 SN+ formulation designed to protect against catastrophic engine failure associated with Low Speed Pre-Ignition (LSPI) is now automatically covered by the new GF-6 specification.
Since Castrol moved all products to the new formulation in 2019, you can be sure what’s in the bottle already meets the new GF-6 specs.
