Finally added side skirt.
 

Seems to help. I drive 360 miles total every other weekend to take my kids home and I never made it above 34mpg on my Fiesta. Last two trips I averaged 35 then 35.3mpg. With a mix of up hill and downhill. Seems to be with the 22.00 I spent. Same gas station also.

Four Thanks but no comment? :confused:

How do you attach them? Any thoughts about adding spats to the ends?

I just us screws with lock washers.

Not sure about adding spats yet. Just wanted to see if the screws vibrate loose first.

Looks like mayb just an inch or two extension below the running board, no? I like that it is in black though. I used white gutter, cut it, painted it flat black. But you can imagine I have had to repaint in whole or part twice since installing because any scratch exposes white under the black.

Looks good. Subtle, could probably have gone lower but it's almost certainly going to have no negative consequences at that length.

Installed upside down, right?

I wonder about the other sizes available, like with deeper vertical flanges for instance.

What's this one, about 1-3/4" deep?

Wow...i guess every Lilttke bit helps but I wonder if gping closer to the ground would help more?

Let it grind, right?

There're lots of things that would help more. This would be about ROI. Maximum Return On minimal Investment.

Oh, welcome to Ecomodder.
