The T6 Synthetic 5W-40 and T5 Dino 15-40 are now rated by Shell as Jaso Ma2.
The T5 was reported as such, with a quote from Shell, on BOBIOG forum, and I emailed Shell about the T6 and got the same reply. Shell said that they didn't change their formulation and it carried the MA rating before as thats all they tested it for. When they tested it for MA2 it passed. In effect, then, its always been MA/MA2.
Thought it worth reporting as several folks have stated they use it and at least one said he'd been using it for a long time.
Its up to each person to decide for themselves.
