Changing weight makes comparatively little difference on highway FE (relative to city). If you're running stop and go traffic, or running up inclines, then extra weight will make a significant difference.

Also, in your case, that 150 lbs. is likely only 5% or so of the total weight. That may have improved things but you'd need to average a number of tanks to see that subtle a difference.
