This is in my wheelhouse.
As an owner previously of a 2005 Tacoma,
putting 750k miles on it,
and a 2018 Tacoma,
putting 143k miles on it,
both 2.7L 2TR FE,
I have some specific ideas for you, OP.
First, please use 0W20.
The truck runs so much better on this grade.
Second, the issues that came up for me
were the standard oil consumption
from valve stem wear
and piston ring coking.
I had a heck of a time passing the dreaded CA smog check.
Code P4020, catalyst below threshhold.
The only way to stop my dash from lighting up
like a Christmas Tree,
was i
to have a factory catalytic converter installed.
and yes it was expensive.
I used and recommend
Black Bottle Castrol EDGE HM 0W20,
available from Walmart, store or .com,
at ~ $25/5qts.
It is a low phosphorus formula.
Your truck will smile from headlight to headlight.
Hope this helps.
