Not sure a PDS is going to tell you which choice is better. However, HM 5W-30 is actually a bit thicker at temp...
Well it used to but Mobil's PDS now sucks. They used to publish HTHS which could be a deciding factor on which oil would be better in the OP's situation. Went to Mobil's site today and much of what they used to claim is no longer listed. So I have to say you are correct. When Mobil did publish HTHS 10w-30 was much higher than 5w-30.
