Gas light, doesn't that require a nice flourescing bag called a mantel over the gas pipe to get optimal light out of it? I remember even the old Coleman lamps had that bag tied over their gas generating tubes.
My light comes on after about 160 miles and it takes around 4.0 to 4.2 gallons to fill up. The manual says I have a 5.8 gallon tank, leaving me 1.8 to 1.6 gallons before I'm empty. I have never tried to run out of gas before I fill up though.
My light goes on right at 165, I have gone 20miles further but get to scared to go further. I start thinking about how much sitting in traffic I have done and get chicken to go further. I have never had it hit 5 gallons on a fill up yet. Maybe 4.5 give or take a little bit.
