I have some leftover 5W-40 Valvoline synpower MST. I was about to buy more oil when I realized I already have 11 quarts of this stuff and it meets A40. Any reason not to run this in my Macan?
I'm hesitant because they don't seem to make it anymore and it seems there has been advances in oil for direct injection and lspi since this was made. The alternatives would probably be Mobil 1, Castrol Edge, or Amsoil Signature.
