I never really paid attention to the whole Dexos 1 thing until I got my Sierra. Maybe a stupid question but: Am I to assume that any brands on the shelf that are listed at the Dexos 1 site, even though not specifically labeled as a Dexos 1 oil, can be used now without issue as meeting the Dexos 1 requirement? I was disappointed that Kendall wasn't on the list since I have four cases of their 5W30 full syn waiting to be used. The Dexos 1 "need" was the reason I just bought six 5 qt. containers of Castrol Edge, with $5 off per container coupons, from Walmart.
