NO, GC is 0w-30 only. Why only 10w-30? I use 0w-30 with no problems here. My engine recomends 10w-30, 5w-30, 10w-40, and 5w-40, but GC gave me a great UOA after 7400 miles.

(A 0w-30 will pump better on cold starts, but operate the same as a 10w-30 when up to temp)... just keep in mind- GC is a "heavy" 30 weight.
