After looking at all of the data I gathered from driving with and without aeromods I came to the conclusion that they just are not worth it. Aerodynamics are an important part of efficiency of a car however I was able to find far better results just by slowing down on the highway. I drive 55 mph instead of the typical 75 that most people drive and I am getting great results. Velocity in the drag equation is a squared factor, when compared to Cd and Area, which has a much greater impact on the drag.

The mods have cost me upward $80 in material alone and I don't see me recouping that cost in gas and electricity savings. I had a lot of fun during the process of experimenting and testing the mods and gained some good insight.

With the weather now pretty cold where I am, the impact of the mods compared to the impact of the weather is insignificant. The mods were also becoming a pain to keep in good condition. The miles put a lot of wear on the coroplast parts I used and it was getting tedious to keep up with the repairs.

Here's a link to all of my recorded data:

I'm not calling this goodbye forever but it will be goodbye for now. I hope even just one person got something out of this thread. Thanks for all the support everyone!
even if I get a few more MPG it's still worth it the cost goes down fast per mile gained gas is still 4$ a gallon locally and if this"war" happens it will top 5$ a gallon maybe even 6$ a gallon... the only butter zone is 40 to 45 mph which is not do able on the freeway at that point i can get about 30 to 33mpg in this v8 engine
