I can tell you exactly how far a 300D will go. I took mine exactly 504 miles when it ran out of fuel on the New Jersey Turnpike. Seems the fuel gauge had my name on it that day because the gauge was still on 1/4 full. I'm just tooling along remarking on the fantastic fuel economy because I reset the trip meter after each fill. Then wham Fortunately, I pulled right over and did not try to go to the last drop. Two mile walk to the station Fortunately got a drive back and it started without too much difficulty
