I used XD-3 0w-30 this in my wife's 2003 Acura TL with the Honda 3.2L v6. (the UOA is posted somewhere on the UOA section). Your Odyssey probably has the same engine architecture as the TL.
I think I am not off side by disclosing that my OUA (with Dyson Analysis) on this oil was decent, but IIRC Terry advised that this XD3 0w-30 had too much phosphorus for this engine design. That's some pretty specific advice from as good and credible an authority as you can get on this board. I'd apply it to your new odyssey if I were you.
Phosphorus aside, on your point of is it too heavy - I thought it did OK, but that was strictly in a hot summer. XD3 0w-30 is way on the heavy side of a 30wt, and is darn close to a 40wt. I certainly wouldn't try it in the winter.
I was a religious 5k km's M1 user for the first 60k km's. Apart from 1 OCI with XD3, I'm now using PZ 5w-20 for my wife's car. If you're interested, I have a 9k km (5.6k miles) OCI on the PZ 5w-30 that I'll be sending in for analysis...and I'll be posting that within a month.
I hope this helps. Enjoy your new van!
