Took time to average results over 4 months.
Sliders do not seem to make a noticeable difference.
Front bumper costs about 1.6 mpg depending on speeds. I have reached the conclusion that aerodynamics are more to blame than weight.
Before anyone points out that there are countless variables that affect mpg... that's the reason I didn't post absolute numbers--only the difference-- and in my case the sliders, then the bumper were the only thing that changed.
YMMV
