The indicator is based on "normal" oil. It has no way of knowing what kind of oil you have.

Personally, as long as the engine is under warranty, I'd change it as required by the DIC. That way, if something should happen, that's one less fight with the dealer. I probably wouldn't run other oils down to 0%, but with Amsoil, I would change "as required".

If you're worried about the warranty, why are you using amsoil. They are not a Dexos approved oil, and this has a more chance to void your warranty.

It won't void the warranty, but it might give you extra hassle. But not changing the oil regularly is another point of contention. That one might be harder to win.
