Yes
Valvoline claimed 4x better
Castrol is claiming 8x better
Just a another twig on the pyre.
I'm thinking that the Castrol people have probably run their OWN Seq 4A tests. (Somehow, I doubt Valvoline would be keen to share their info.)
Valvoline's tests were likely conducted sometime mid year. Castrol is late to the party, implying that their tests were conducted at a later date. This suggests that more recent M1 batches might also be failing the 4A test!
Will other oil manufacturers join the dogpile?
How long can XOM stonewall?
Has anyone found some shred of real data supplied by Castrol to support the
8X claim?
Stay tuned for tomorrow's episode of "As the Camshaft Grinds."
This is kinda fun!
