just filled up a full tank,

my dash read:
MPG 17.6
MPH 27.3
The last full tank was around 325 miles or so.

after I filled up the dash read that I have 335miles before I run out.

I put 16.553gallons at $3.08/gallon~ $50

The dash stated 31mi til empty.

SO that's rougly maybe another 100mi if I'm lucky considering the reserve is 2-3gallons. Which is about right.

Hrp783.....have you ever used any fuel cleaner/ additives? I've heard nothing but horrible things from them but maybe trying a system clean might help, I dont know though. Just my thoughts.

 

Did you get the only exclusive G35 hybrid?

 

no never, i think im going to tell the dealer and let them check it out, maybe my senor is off??

450 miles!!

when i was on a long drive, full tank all hwy miles, it said, and only once have i seen this 420miles

 

My gauge sometimes moves from 1/4 to 1/2 in a matter of minutes and back down. When I fill up after "---- miles to empty" and driving for about another 20 - 30 miles, I can only put in 14 gallons at the most.

I have taken it to the dealer and they have not found a problem. They said that there is another test they can do but the tank has to be as empty as possible.

 

I have a 2007 g35 sedan and the electronic meter reads 65 miles to empty, but the regular gauge is still at the quarter tank mark. anyone else haing this issue?

 

yah that happens to me.

So I was talkin to a buddy from Cali, who is a tech for infiniti, as soon as i mentioned the problem, he said, disconnect the neg cable from your batt and wait 5 min, and connect.

he said the car learns the way you drive, and it thinks u will run out faster then it actually will.

so i did and it is performing like normal.

he asked if I drive short trips alot in town.... yah i do.

so try it and see if it works.

i have not had to fill up yet since my last fill up when i posted the info, ill keep you upto date

 

MY '07 G 35S has the same issues. I believe I read on this site that there is some sort of gauge--I don't remember what kind of gauge-- which reaches into the gas tank. If the tank has less than 3-4 gallons left that gauge may become damaged. So the G warns you when you are coming close to the gauge damage point.
