I'm with Frank Lee on this. Those little lips cannot be doing much. Now one guy (I forget his name) put a big honkin' World of Outlaws whale-tail on a VW Beetle and got good results but it was far bigger than those little ornaments.

Of course, you could prove us wrong. Get some cardboard and duct duct and make your own little lip and tell us how much it improved MPG.
