MPG overhead display correct with 35's?

[Ben824]

I have the stock overhead console with the MPG display and it is fairly accurate within .2-.3 compared to my math when I divide the fuel filled from empty to full by the miles traveled. I corrected my speedo and verified it's accuracy via GPS speedometer app on my iPhone.

To the OP are you looking at Avg MPG or Instant MPG on the display? The instant is always changing and will drop real low when really putting your foot into it going up hills so for it to say 6 going uphill sounds right and 18 cruising flat sounds right as well if you are re-geared. If your Avg MPG display is saying 6 then you may want to check it out and have the speedo verified and fixed if it is off.

Have you reset it recently?

I usually reset mine everytime I fill up. I would figure out if your speedo is correct but with factory gears and 35s that seems like what your average would be close to as mine is about 12 around town on 33 with factory 3.55 gears.

C'mon. Those over head gauges are up there to look pretty. I've never seen one accurate.

They've been damn close on ever Cry product I've owned so far. Except the XJ, but that's because the speedo wasn't quite right.
