Additives.........

[mhl03]

At what point would you add any kind of additives to the oil due to milage? ( if such should be done .)

I think you could add additives from the get-go. I actually just changed my oil yesterday morning and I used castrol gtx 10-30 and prolong engine treatment. It feels great so far. The take off feels so smooth, the only thing that I can compare it to is if I were reving the engine in neutral, its that smooth. It also makes your car stop smoking I've heard, if you're having that problem, lets hope not though lol. It also sems as if its improving my fuel economy, but ill check that to be sure on my next fill up. But yeah, the sooner the better I would imagine. And a fuel additive with every fill up.
