    Also I was wondering if that is truly the right viscosity as well.

    From what I understand alusil blocks need high moly for better friction reduction. Though I could be wrong.

    Hi, I am new here but have lurked a bit. I have a 1993 400E and currently have Amsoil EFM in it and was curious about whether the new HP-X is the best oil possible due to the extremely high moly for the alusil block.
