Amsoil Signature

I know this is beat to death constantly...but I am wondering if anyone is using Amsoil in their ZL1 or SS? I do the "once a year" Amsoil signature and their filter in my 09 C6 Vette and absolutely love it. Its a guaranteed 25K oil if used properly. My 18 1LE has 4200 miles and I am wanting to swap to Amsoil...but not sure how finicky GM is about oils.
