I've tested my luck while driving with my gas light on 3 times so far. The first time I went 26 miles after the light came on before I got scared and fueled up. This final time I went 40 miles out of neccessity before I filled up. This has been the farthest so far. I'm kinda scared to push my luck but atleast I know I can get atleast 40 more miles after the lights on.
Nope, I have a 1995 Camry and on EMPTY (went 42 miles when light was on, pushing my luck as well) my car filled up completely to 14.66 gallons. That was when I pushed the tab down on the pump so I didn't have to hold it while pumping. The older Camry's are amazing.
