Uhg, i used to get about 410... Now i get about 205, bigger tank too. I never actually fill up lately, but i used to put about 4 gallons in the eclipse and drive around 100 miles, i put 4 gallons in the stealth, and get around 45. Buuuuut, i suppose going from a 17.0 1/4 mile to a 12.81 is worth the price in gas.
