There are stories floating around the Hyundai boards of people who have killed their transmissions by putting in Dex/Merc fluids or anything but SP-III or Amsoil.
So it is ok by warranty standards to use other brands of SP-III?
I was going to use Hyundai SPIII on a Mitsubishi Eclipse and the customer flipped out that I wasn't using OEM mitsubishi fluid. He said that 'what do you mean it's the same thing, Hyundai is Korean and Mitsubishi is Japanese, why would they use the same fluid?' He was really angry.
I know better and I use Hyundai SPIII in Hyundais, Kias and Mitsubishis when they call for it. I don't see the problem.
