did my first oil change on my firehawk today (since i bought it, that is). i used GC 0w30. 5 quarts were yellow, one was the greenish color...
the labels were all the same so i'm not sure what to think. i just dumped it all in... hopefully nothing wrong with that.

Do you still have the bottles? I bet the yellow ones were date coded as M0502 or newer, since GC is not green in color after that date code, it's now a different formula (still very good though)
