No major aero mods, just got some transparent tape and seal the top grill. Inflated the tire pressure to max, I also have modified intake & magnaflow muffler (more free-flowing) seems to help with mpg, if you can keep your foot off the gas

Also I just added in home-made Oil catch can to put between PCV and intake manifold; keeps oil out, preventing sludge buidup, and keeps from degrading octane rating of fuel. I feel like it improved mpg, but do not have scientific method to prove that it does.
