I never really look at that display option. I'd rather calculate my tank capacity on road trips. More accurate and significant, if you ask me.

I manually calculate my MPG every tank and the gauge IS accurate to within ~1mpg. The reason it doesn't appear to be accurate for many people is because they don't use it properly. The gauge shows the average mpg SINCE YOU LAST RESET IT, you have to reset it at the same time that you refill your tank or it will not be accurate. 32mpg is believable if you maintain a relatively low and steady speed in a high gear. Yes, the prius gets better mpg than the 350z, and it is a boring car... if you want fun buy a 350, if you want boring fuel economy buy a Prius. PLEASE don't start a bunch of ignorant posts about "miles per tank". If you have one vehicle with a 10 gallon tank that gets 40mpg (400 miles per tank) and another with a 20 gallon tank that gets 25mpg (500 miles per tank), you would actually have more "miles per tank" with the car that gets lower gas mileage.

It's accurate if you use it correctly. If you don't reset it, or just measure for 5 minutes after you reset it, it's not going to be accurate.
You can't say it's not accurate because:
"I reset it and coasted down a hill and got 50 mpg!"
Well, when you're coasting down a hill, you're not burning much gas, so it's accurate for the period/action you're using it for.

Truthfully, I’m not that far off what adamciya350 shows for mpg stats. I check the mileage manually and compare this to the car’s “computer,” and the calculations are nearly identical.
OK… I’m older and probably drive more conservatively, but the exceptional mileage I get with the Z is certainly surprising. After all, the car is moderately heavy for a two seat sports car ( when you compare the weight to something like the Porsche 911).
But then… isn’t the Z engine shared across the Nissan Line? The Nissan Altima V6 turns in very good mileage. And yes... I realize the Altima is “chipped” differently.
