These tell you how much gas you're using per hour, Instant MPG, Throttle position and load. It's helped me figure out where are the best times to using neutral coasting with the engine on.

Example: Driving down a grade a 55mph, the MPG gauge will read 110mpg, and the GPH will read 0.71. I know my car idles with 0.21gph, so I'll shift into neutral and my MPG will go up to 320.

If you leave it in gear and just coast, you might have fuel cutoff, in which case you go to 9999mpg!!
