WOT Junkie and avid corn burner
Hey, has anyone else, other than Black_Cat and I been getting crappy gas mileage lately? I fueled up the other day and my average mileage was 14 mpg. All mods are in my sig, of course. This driving was done mostly around town with seldom highway driving. My fuel needle didn't use to move until 50 miles in. Now, it starts dropping after 20 miles. Is it really just the heat lately? Fuel trims are very neutral. EGR is on and O2's are only a couple years old.
