    Even after driving like a grandma i still get 20.9mpg at most. This was after a few days of running premium.

    Today I rocked out and gave it some gas. Just burned .3 gallons more than usually

    22 mpg is pretty decent for city driving. The stock t-stat will give you the best fuel mileage. The 180° will lower your mpg a little. The 160° is the worst as far as economy goes.

    It all depends on driving conditions and such. But I would roughly say 1-2 mpg.

    I do about 80 miles a day and get about 28 highway and 24 city. I just use the cruise and am easy on the brakes and accel. That is with a motor that came from a junk yard for 300$. stock with a basic tune up.

    I average 20 when I'm heavy in town, and around 24-26 when I drive like my mom. The best I got was 45 driving to denver with the cruise set at 80mph, and 37 on the way back. (downhill/uphill) I average about 35 highway around here and I live at 6,200 ft. One thing though that helps me is when I coast I do so in neutral...however I've heard this can be rough on the tranny. Is this true and should I stop?!
