There's more than just oil ratings, there's info on extended oil changes and other info. The writer of the blog doesn't recommend using adding additives, but using a highly rated oil. In his question an answer section, he states he uses Quaker State Ultimate Durability (But, I can tell you that for my own High HP engines, I have chosen to run the 5W30 Quaker State Ultimate Durability, referenced above, as the best overall 5W30 for my needs. NOTE: He doesn't have a Honda Odyssey.)
The Quaker State Ultimate Durability series are rated highly (can be had for less than $5 a quart not on sale). It's what I'm currently using.
6. 0W20 Quaker State Ultimate Durability, API SN, synthetic (gold bottle) = 124,393 psi
9. 5W20 Quaker State Ultimate Durability, API SN, GM dexos 1 approved, synthetic (gold bottle) = 121,396 psi
17. 5W30 Quaker State Ultimate Durability, API SN, GM dexos 1 approved, synthetic (gold bottle) = 113,377 psi
