I am at 97,xxx on my Kia and of course the powertrain warranty ends at 100K. I have been doing drain and fills every 15K since new with Kia branded SP-III fluid and the fluid comes out the bottom looking the exact same as it does coming out of the bottle. So that part is good.
I have read various places that SP-III is not really that great of a fluid, and that there are better options out there for both shifting and longevity. So, is it advisable to switch, or to stay the course with SP-III. And if I do switch, should I do a complete fluid exchange or just keep draining and filling?
