Toyota USA Says 0W-20… I’m Running 5W-30 in My Tundra (Here’s Why)

In this video, I explain why I’ve started running 5W-30 oil in my Toyota Tundra with the V35A twin-turbo V6, despite Toyota North America recommending 0W-20. We dive into Toyota owners manuals from Mexico, the UAE, Thailand, and Russia to see what oil viscosities Toyota approves globally for the exact same engine, then I show the oil going in my truck, review my Blackstone oil analysis test going out, and discuss real-world fuel economy impacts. I also break down the often-misunderstood difference between warranty coverage and recall coverage, especially in light of the V35A recall, and explain why oil choice does not affect recall eligibility. This video isn’t about telling anyone what oil to run — it’s about sharing data, documentation, and real-world experience so owners can make informed decisions for long-term Tundra ownership.
