My low fuel warning light comes on when I have an 1/8 of a tank left. Is this normal? '08 owners do you have the same issue? The car has done this since I got it. I'm also getting pretty bad gas milage, 16mpg, but thats a discussion for another day. As far as the fuel light goes, once that light goes on doesn't it mean your running on reserve gas? Last time it came on I decided to just wait until it got down closer to E but a few miles after the light came on at an 1/8 of a tank it started to idle strange. Any thoughts?
