Toyota care- Dealer service

Good morning Tundra crew

Coming up on my “free” Toyota care-
6 month/5,000 mile service -only have 2,000 miles in 6 months- thx to take home company truck

This is my first new vehicle ever-
I have always done my own service
( what I can handle ) on all my vehicles

I have seen the posts on here about SHITY dealer service and issues found after service- If I go I will definitely check behind them.

I can’t believe they don’t change the oil on this first service -shouldn’t it be changed for “break-in” ? Do they do any thing worth while like computer updates etc. Will I void warranty if I don’t get the service?

What oil do u all use/ recommendations?

I have had previous issues on my other Toyota’s (2- 4 Runners and FJ)
with aftermarket oil filters- and have used Toyota filters ever since- should I continue this on Tundra?
Recommendations ?

Sorry for the long post
All help/ suggestions APPRECIATED!!
