The GC is getting low in my area. I found 10 quarts this week. Most were 412 or so but found 0233 that was green also. Most dates were 01xx or 0521. Don't know how long the GC will hold out.
Noticed somethinge else. It has been said the base oils are the same with the GC and the new stuff but they don't even begin to smell the same if that has any meaning!
