I've got Super Tech in there from &8^### mart right now.
My "FRIEND"

oke: gave it to me so I put it in.
Is this decent stuff? What's the best out there.
Also, I'm running NO LS additive, for a while truck didn't chatter or anything and will hook up both tires, on blacktop everytime.
Now I think I have a chatter when I turn. Hope I didn't hurt anything.

How much LS additive should I add to start with? 2 oz ?
I want just enough to stop the chatter but want it to still hook up.
