Theoretic perfect AFR for cruising is 14.7 (stoichiometric ratio), so you are actually on the rich side and sending a bit more than necessary unburnt fuel out of the tailpipe. I say "theoretic" as not all engines are going to run smoothly at that AFR - mine does and my steady highway cruising is even a few tenths higher depending on weather conditions, etc.
