Hey TMACOD
I think a lot of us are also wondering the same thing. From what I've learned, there may still be some Valvoline Blue "Classic" available. And I think Amsoil still offers a CI rated oil. Because of costs and distribution most if not all manufactures have switched completely to the CJ-4 oil.
Take heart though, it's not that the CJ-4 oil is Bad, rather it's just not as Good as CI-4 oil. I've simply chosen to reduce my oil change intervals.
