I definitely do my own oil changes but with two years free service, I'm going to let the dealer do the scheduled 10,000 mile change after I do it at 5000. I'm thinking about sending a sample from the 5000 mile change to Blackstone too.
I just joined the Tundras forum and there is obviously a lot of chatter there about the bearing failures. They are sending oils sample to be tested as well and the comments from Blackstone mention that high silver readings could mean bearing wear or solder from the oil cooler. The tests from Speed Diagnostic don't even check for silver and one member sent an email to Speed to ask about that and they replied that there is no silver in the bearings so no need to test for it.
I know that Toyota made changes to production of the engine earlier this year and even the early ones failed at a rate of less than 1%. I test drove a blue Tundra and they unloaded the one I ended up buying as I was at the dealer. I wanted the late build date.
I haven't followed this Tundra engine thing much. I know it wouldn't sway me from one if it's the vehicle I wanted. I know the new 2022+ Nissan Frontier engine has a few reported catastrophic failures that blew things up on the Nissan forums for a bit.
Looks like the Tundra engine holds something like 8 quarts of oil. It's got a nifty drip catcher at the base of the filter that you can shove a piece of hose onto so it doesn't drip on the frame. One of those fiber under covers has to be unbolted and pried out of the way to get at the filter. I think the FSM also suggests putting the electronic retractable lower air dam in service mode as well to get at the filter, but you don't need to do this.
