I'm not sure if this has been updated elsewhere on the forum, but I was able to purchase the PIDs via an in app purchase for Dash Command, and Oil Temp was in there! Big thanks to whoever helped out!
Oil temp is the only reason I went with Dash Command, and I'm thrilled it's all working! There were many more PIDs in the file from Toyota besides Oil Temp - well worth the 9 bucks US.
and thanks @
HRTROB for putting together a nice dash for the 86.
