GC available in 0W30 only?

[servantwong]

I am new to GC.
I went to local AZ and found GC available in 0W-30 only. I need 10W30.
Does GC available in other grades?

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.

going to a lower W rating and keeping the operating-temp weight the same should be no problem for any engine- better in most cases.

(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.

I don't dispute this, but it always seemed strange how the GC pours lik e water compared to other oils that I have used.
