Shortly after I posted the thread about oils and intake valve deposits (IVD
), it appears Valvoline just made a recent update to their PDS for ME. It's dated 2/19/20
Much improved Noack.
0w20 - 10%
5w20 - 8.5%
5w30 - 8.2%
However, as Gokhan pointed out, it appears SA is far more important at keeping them at bay than Noack.
I'm sure the Valvoline ME oils are great. Valvoline makes a good product. Link
