Have you considered regearing it? What RPM are you running at ~50mph?

When I first removed all of my interior, I immediately saw about a 20 mile increase in my total miles on my tank. From high 200s, to low 300s.
At freeway speeds, I'm running 3000 rpms at 65mph. At 50mph, off hand, I'm running mid 2's RPM in 5th gear. I've thought about adding a custom taller 5th gear, but it can get pricey. I think what I would save in MPG with a better 5th gear wouldn't equal the money it'd cost me to get that done. Especially at 200k miles and maybe another good 48-60 months left of life for the car.
Mainly why I'm planning on dropping more weight, and adding aero mods. Only trying to squeeze another 5-10mpg out of her. The Aveo will never be able to achieve ecomodder top 10 status MPG.
