Then either the buyers are atypical here, or Infineum may need to update their best seller status. Around here 5w30 is definitely the best seller. I've seen 10w30 bottles of various brands collecting dust on the shelves, but 5w30 bottles are always fresh. 5w-20 is catching on too.
I assume we are referring to the US market.
