I sometimes use fuel additives that "improve gas mileage" in my gas tank, but after doing the math I realized, It's just not worth it. The 5 bucks you pay for a bottle of this stuff only get you another 10 - 15 miles or so per tank. For that, you could just put in $5 worth of gas and probably get more than that. Any opinions on this?
