Mine has been changed several times... dont ask... I use Mobil 1 LS. You can add the additive if you want. Read the label on the bottle it says that for "extreme performance cars" to add the additive... just depends on if you feel your driving is "extreme"

I also changed my tranny to Mobil 1 ATF... WOW major imporvement.
