Well first of all, nothing has fallen off or melted, so that is good news. As far as effect on FE, it's hard to say for sure. Comparing today's drive to work with one a week ago which had the same temp and wind direction and speed, I noticed a 2 mpg gain after adding the rear pan and removing the passenger side mirror. But I can't be sure that the gain can be attributed to those changes because 10 days ago I had new tires installed which tanked my FE by 6 mpg. It could be the new tires breaking in.
