Just looking for some sort of consistent behavior. When I see 100 miles left, I start to wonder, "When is it going to go to dashes this time?"
Thought it had something to do with current Avg. MPG. but in that regard, I get fairly consistent MPG. Nothing to explain the miles remaining indicator from apparently randomly going to dashes over a range of 70 to 30 miles. That is a huge range, requiring a huge MPG/tank variance, I don't get that variance. I don't track/beat on it, and I drive for MPGs.
I used to have diesels, and regularly got >> 600 miles per tank. I'm spoiled and trying to figure out the fuel level system so I know how far I can push it.
I pushed the Legacy to 603 miles on a tank, the dashes were on for a LONG time, and it only took 17.3 gallons, and I pack it when I refuel.
BTW, my VW diesels had a tank rated at 14.5 gallons, but could take on over 16 gallons when refilling.
