Speed vs. fuel economy: 2010 Jeep Patriot 2.4 CVT 2WD graph/chart

If you spend most of your time driving the highway then I would think it would be worth doing the lower air dam. If on the other hand your mostly city or evenly mixed then like Metro said you would likely lose the benefit in real mpg terms.

It's out on the highway 90-95% of it's life.

How effective would that black garden edging stuff work ?

Kat,

We say that an air dam gives you most of the benefit of a belly pan, with a fraction of the time and expense; members usually report approximately 3% better fuel economy with an air dam.

See: http://ecomodder.com/forum/showthrea...rly-21149.html

I had a 2007 Dodge Caliber w/CVT. Altho there was a low mode, it didn't have "shift mode" which was always silly. The CVT was programmed to give best MPG at 2000rpms. Above 60MPH the CVT was at its maximum ability to shift "higher", so rpms increased above 60MPH. So I accelerated slowly, keeping rpms close to 2000 & tried to stay near 60MPH, unless traffic got stacked behind me. While most Caliber owners averaged 26-7MPG, I averaged 31MPG with E10 fuel, with a high of 35MPG. Using E0, I averaged 33MPG with a high of 37MPG.
