Details have been released about the much-speculated API GF-6 specification for motor oils.
Starting May 1, 2020, oil manufacturers will be required to move fluids to the new API GF-6 specification.
With the new GF-6 specification comes a brand-new set of engine tests not seen in the industry before, and splits the API specification into two categories:
GF-6A applies to grades with viscosities 0W-20 and greater
GF-6B applies to grades with viscosities lower than 0W-20 (Grade 0W-16)
According to Wakefield Canada, makers and marketers of Castrol oil in Canada, the transition to GF-6 also brings a new API “SP” spec, which replaces the transitional API SN+.
“This means that the GF-5 SN+ protection against catastrophic engine failure associated with Low Speed Pre-Ignition (LSPI) is now automatically covered by the new GF-6 specification,” a press release from Wakefield states.
The company says Castrol has already transitioned all applicable automotive fluids to the new GF-6 specification. This will be reflected on Castrol labels starting May 1.
