In the owners manual it states that "remaining fuel when only 1st (E) segment starts flashing approximately 2.8 litres (0.74US gal, 0.62 Imp Gal) Does this help?

I have read that, but after thinking about it again I guess it does! The manual is very short about this.
Because if I was at "0.4", I can assume I have until ~".7"
But that doesn't explain why I could still fit over a half gallon...
I'm not saying I want to run right to the edge every tank but I still feel that I have to stop early all the time.
I understand that gauges are digital and won't be perfect, so I may pack a little extra gas in a safe container and actually purposely run out one day just to see how far the gauge goes. Thanks for your help guys!

I've had a similar thing happen, and the gauge is definitely waaaay off.  On one occasion the gauge said that I've used 17.someting liters, and with one bar left I could still fill it to the top with less than 13 liters.  On another occasion, the light started blinking and the reserve fuel counter started to count, and I still could fill it up with 13.5 liters.

Basically I calculated around 3,7 l/100km, 1/3 highway, 2/3 stop and go city traffic. The indicator said 4,5 l/100km.

To summarize, the margin of error on average is between 25-30%.  :) Pretty accurate for a Japanese machine.

For gas mileage is not a big deal, but I just hope, the other parts/electronics/computer  on the bike do not have that margin of error.

P.S.  Maybe this explains why the bike can go up to 180 km/h :)
I expect a 30% discount on my next Honda bike, because of a mistake by the Honda dealer.

I think someone else alluded to this, but the likelihood is that the same computer module that is used on the CBR500R/CB500F (where the tank is slightly smaller) is also used on the CB500X (cost-saving). Hence, it'll always be 0.4 gallons conservative (i.e., you've got 0.4 more than it thinks you do, or we can go however far 0.4 gallons will take you more than the 'reserve' would allow on either of the other 2 rides).

Make sense?

Never gave it much thought I go by the odometer  but I think you are on to something and it does make sense..

Okay, at 200 miles the fuel gauge dropped to the last bar. At 235 miles the last bar started blinking and showed 0.3 fuel. I filled up at 245 miles on the center stand up to the metal splash guard with 3.8 gallons.

I'm just running this around in my head my avg mpg read out always shows low so if the R&F have 4 gal tanks that's 16 quarts the X 18 quarts that like 12% dif so take that add it to my  avg mpg read out ..BINGO spot on what to ya'll think  What I'm saying is I think Billedtimmy in his post is right..

I do the same except every 200 miles, but with all the cool gizmo's in our speedometers it a shame they don't work better..
