In roaming the oil aisle at my local walmart the other day i was reading the back label of the TropArtic oils they had. I noticed on the 10w30 TropArtic Syn-Blend that is was listed as a SM/CF oil (along the top, not in the API donut), yet the 5w30 was only listed as a SM oil (No CF).
I recognize just plain old CF by itself does not do a whole lot for anyone since while it is still valid, its been replaced, but i just found it interesting, especially since on paper the specs for TA 5w30 and 10w30 look so similar.
