WSS-M2C931-B Oil

Hey guys doing some research and need some help. I am getting conflicting answers regarding oil for the '13 GT500.

FORD 5W50. This will be the default but $14 per liter is a little too much.

REDLINE is another 'B' approved oil. $12 a liter

I have read that Castrol is another 'B' approved, but cannot find it on the PDS, it’s SM approved

Mobil1 is another SM approved but I cannot find the 'B' spec on its PDS.

Castrol would be the cheapest but I need the proof.

I also do not want any AMSOIL responses since they do not even make a 5W50 oil and cannot take the time to get it tested to these specs:nono: .

Yes this is another oil discussion :dancenana::dancenana::dancenana::dancenana: .

I just want to know what I can use so I can get the cheapest alternative


Thanks

Maybe I am crazy but I am going to be using Schaeffer's Supreme 9000 in mine. I have not seen anyone else here talk about this oil, I'd like to hear any input from others about experiences with this oil. I run Schaeffer's oils in all my vehicles to include high performance motorcycles and have been quite pleased with it.
