My economy is pretty good. I can go to my gf's house and back (45mi one way) at 100+mph and when I'm home, it's at like 3 bars of gas left. If I baby a tank it's maybe 2 weeks idk. I have a list of mods on it, so I tend to not baby it, and it still doesn't burn the gas too bad. Tunes also massively help with the reliability surprisingly. I have noticed the gas smell, irregardless of if I have leaks or if everything's perfect, but I usually assume I'm making it up
