Maybe it's just me but I have heard other drivers complain bout this too. About 2 months ago I figured I should keep an eye on what kind of fuel milage I am getting. I buy my gas primarily at the Super Wawa near were I live. My milage has varied from 10.8 mpg to 14.6 mpg, the latest being closer to 10 mpg. I altered my driving habits to get better gas milage but the opposite seems to be happening. My Cruise has been running great without any performance changes or any new mods that would affect my milage. Is there something going on with the gas I am buying?
