You can't use that as a fuel guage. It's an average measurement based on driving conditions within the past miles driven, same as the mpg reading. That's what the fuel gauge is for. If you have a single dot left, you probably won't make it 200 miles unless the car suddenly achieves 100 mpg. Fuel starvation is one thing, but how about taking some responsibility and just filling up before a long trip. It shouldn't change as much as you had described, but theres no distance till empty gauge that's 100% accurate. I've never had this problem...then again I go by how many miles I've driven since my last fill up.
