Per Amsoil Magazine:
"....Amsoil Signature Series is undergoing a revolutionary reformulation that promises to usher in the next generation of motor-oil technology."
For the XL, HM and OE - already meets or exceeds Gf-7 and SQ standards.
Just an FYI. I was curious if/when Amsoil was going to reformulate SS.
