For reflective object textures I have a few rules I use:
1) Never use ambient. (I actually only use ambient for light source type
objects).
2) Be very conservative on the use of diffuse, adjust according to material
type. (for textures like polished chrome or brass use diffuse 0)
3) Use fresnel reflection with min/max = 0/1, use ior to adjust the
reflectivity level.
