GC is only 0w-30. BC is supposed to be a very good oil though, as good as GC, not sure, but a good oil none the less. It meets pretty much the same specs as GC, but is not green and we are not sure exactly what the base oil is. I have 8 qts of BC that will be used when I am out of GC (in about 3 yrs).

Yep, when I had my LT1 Firebird I had great results using GC, and in my LS1 Corvette the results are even better. I think BC would do well also, but I don't think it's as good as GC.

Nobody can say for certain whether or not the 5w-40 BC is better or worse than 0w-30 GC, as there simply isn't enough information concerning the base stock, additives, or used oil analysis.
