I would suggest changing your fluid at the previous posters recommendation of 30k, there is no such thing as a lifetime fluid. I would not suggest anything but using the OEM brand fluid, I think specs mean less than what was used in the car to begin with. If you do not know what are you are doing than you are probably better leaving it alone if you were going to DIY.

I used to read forums and look for different fluids that may or may not work better than OEM, stuff like Redline and the like. I realized that whatever difference they may or may not make, its not worth the risk of potentially using the incorrect fluid. Engine oil is less risky in terms of brand, I would say Syntec or Mobil 1 will be about the same as long as you are using the correct grade. When it comes to differentials and transmissions, use the original stuff.
