I posted this question in another tread then decided it might need a thread of its own. This is my first post so bear with me I went to my local Autozone today and found six GC ,bought same. While I was changing my oil the neighbor came over and he decided to give GC a try, we went back to same Autozone and no GC!! They had USA made ow-30 no a3/b3 no api sl/cf sl only and it is not green. Is this the same oil??
