MPG....For what it's worth

JARblue

I bet at 55 mph in 6th gear, downhill, with the wind at your back, and maybe a tune you could get 35+ mpg

I've gotten over 520 miles on one tank before. Filled up over 18 US Gal, which was over 29 mpg for the tank. And that was at 70 mph on cruise control most of the time.

I've gotten 112 miles on that first dot before - it's the best one!

No but seriously, the way the dots drop off slow at first and then rapidly as you approach empty is easily explained by the shape of the gas tank. The dot gauge is just a float in the tank estimating how high or low the fuel level is, and it doesn't take into account the shape of the tank. Since the tank is larger at the top than the bottom, the float does not drop at the same rate when the tank is full vs empty. I would never trust that gauge.

I could care less about my mpgs, but I religiously pay attention to the mileage I get per tank. Therefore, I know almost exactly how much fuel I have at any given time just based on the miles I have driven since last filling up. I hit the 50 miles left warning and know that most of the time I have at least 100-120 miles remaining of casual driving. I often fill up more than 18 US Gal. Driving habits alter mileage, of course, so I take that into consideration as well.
