no worries man. my car does that too. it most likely is because of the position of the car & gas in the tank.

I always check the gauge even though I have a sense of gas I've used up since last fill up. Sometimes I'll notice that I had more gas in morning than I did the night before when parking my car. During my commute it changes too, in stop&go traffic.

It's not a huge difference, just enough to notice. especially when it was below a tickmark and a few blocks later it's above. Doesn't bother me enough to trouble myself at the dealership

I just fill up the tank it it reaches 3/4 of the way down the gauge.

inaccurate gas gauge. Since the car is on an incline, it will read lower than on actual level.

If you don't understand how the floater works, here is a simple explanation. Mark empty, half and full on a bottle gallon of water. Fill'er up half way. Then tilt the bottle on 45 deg. angle. What do you get you asked? Less than or more than half depending on if you are on an uphill or downhill.

What does half of half and empty mean? But yea, if you are on a incline it will do that, just move your car to a straight surface, turn it off, and turn it back on, it should be fine.

Gas gauge isn't very good. Mine used to read empty with the light on, but there was still 5 gallons in the tank. Bad fuel sender. But still it's not very accurate.

when i put my car back onto a level surface the gas light still stays on and needle does not move...so i had to put gas.. then it worked fine?

well then you were just close to empty. Do you remember how much gas you pumped?

858racer

i dont remember how much i pumped...for some reason im gettin really bad gas mileage

Well if you have an 04, depending on how many miles you have, your engine probably isnt broken in yet. Give it some time and your mileage should go up.

I have an 01 and i dont get good gas mileage either! maybe 300 to a tank.

my 01 sedan does this too
it said i had 1/4th of tank left and when i went to fill up only 3 gallons went in

HappyGilmore

Our gas gauge is not very accurate. Start using your Odometer for a change. You can get a better sense how much gas is really left in the tank. I get 350-400 for a tank. So if you registered 300 miles on the odometer, you have about 2.5 gallons, give or take, left.

Yeah, the gas guage has some problems. While driving mine will drop to empty even if it was just filled. The light will go on and then 5-10 minutes later it will go back up. Its done this many times, but Honda won't do anything since its not something they can repeat and see for themselves.

wat the hell do u guys do to get 300 a tank. what kinda gas do u use. man. i get like 185 on a full tank...lol. what can i do to change this.? sparks, filters what? my car is at like 30,300 and the maintencane light hasnt come on? i thought it was supposed to come on?

vtecman04

it just might be u, fill up again and dont do anything, when u get to the 1/4 tank fill up again and reset ur tachometer
drive around till u get to the 1/4 tank margin again and when u refuel, look @ the amount of gas u pumped and jot that down, now look @ ur mileage and get a calculator.
then do this calculation to get mpg: amount of mileage
amount of gallons used

another problem might be that u might be driving ur car hard, or u have some mods that might lower ur mileage, or u just might be running rich

y.O. KiLLa, you should change your spark plugs, if you are at 30,000+ miles, I think at 30 you should change them. Get the proper ones, and your gas mileage will go up, change your air filter too. I was getting like 175-200, when I changed those I got an extra 1-125

My gas guage does that too. there are times I would have half of a half (j/k), a 1/4 tank, and than it would go to empty, and keep going and keep going, and I will go fill up, to find out I put 12.__ gallons in my tank. That pisses me the hell off. I would let my car sit for a couple hours, get back in, have gas, than it would just start dropping til I had none. It always does that, but I still get good gas mileage.

the gas door is really hard to pry open, you couldn't get it open with out very noticable damage

What kind of gas do you use? Shell gas is bad and really screwed up alot of cars. There was a class-action law suit against Shell back in the beginning of the year for wrecking fuel components.
