Seeking advice for keeping aging CX-5

[SparkYellow]

I recently refreshed these three fluids on my 2017 CX-3 AWD with 155K miles. The transfer case is in the front, differential is in the rear. A clean drain (having waited for the dripping to stop) of the transmission fluid got slightly over 3 quarts out. I filled with 3.2 quarts of fresh AISIN FZ from RockAuto. Did three rounds of drain-fill while waiting for result of the sample analysis. For the other two fluids I used Redline 80w90. Bought two bottles and used more than one after spilling some.

I definitely expect a modern Mazda to last longer than my 2011 MINI (currently 202K miles.)
