    Well i put a full tank in my car yesterday. I drove app 20-30 miles today and im down to half a tank. My car wont get over 15-16mpg even with cruise. The engine light isnt on and i cant figure out where it went, I know nobody has taken it.


    Any idea?

    When was the last tune up or O2 sensor? Got any way to scan the O2 and see if it's lethargic?

    even at 15mpg you should get alot further then 20-30 miles on half a tank

    how do you KNOW no one stole any? sounds like a fuel leak. i dont see any way your engine could use up half a tank in 30 miles no matter whats wrong with it, thats 3.75mpg, thats just not possible. that would be some HORRIBLE smelling exhaust. or horrible smelling something

    edit: did it just sit and idle for a day straight maybe?
