Looks like Tundra finally caught up to Chevy duramax. My '03 duramax called for 5,000 mile oil changes if you were towing and 10,000 if not way back then and running dino oil. My acadia has a oil life percentage thing like GM has had for a long time or at 1 year, whichever comes first. I made it to the year mark a few weeks ago for the first time ever in any vehicle I have owned, thanks to covid. I joined the synthetic only band wagon sometime ago.
