Then either the buyers are atypical here, or Infineum may need to update their best seller status. Around here 5w-30 is definitely the best seller. I've seen 10w-30 bottles of various brands collecting dust on the shelves, but 5w-30 bottles are always fresh. 5w-20 is catching on too.
I assume we are referring to the US market.
