No such thing as a free lunch.

150k miles is a mediocre lifespan for any modern engine that isn't in a racecar or some rare exotic. I wonder if they would have awarded it all those "engine of the year" awards if this information you mentioned was more well known (assuming that Dinan knows what he's talking about).
