Hi There.. Just want to ask this problem on my fit.

The fuel indicator seems like stuck when it reaches "F" (After Refueling of course) for approx. 40 miles, then the indicator drops quite fast (at normal driving) Also, the indicator reaches 1/2 at approx. 100 miles

Is it normal?

 

yup...when I fill it up to the top, I need to drive for approximately 70-80km (40-50 miles) before the needle starts moving. I can usually get about 250-270km (155 miles) before it hits the half way mark, and the light telling me to refuel lights up around 450km (280 miles)...

 

This is my fuel guage readings

1/4 = 100 miles
1/2= 160 miles
~0% = 300 miles

It's not linear

I also noticed that there when you just started your engine, the needle is not the same position as if u driven along time. When you drive a long time, the needle resists moving. But when you start your car later in the day, the needle reads a different and lower and more representative position.

 

I think the level is read by a little bobber thing in the tank, so when its full its pressed up against the top of the tank. The level has to go down so much before the bobber isnt hitting the top.

 

Can't remember where - probably Car & Driver - but I remember reading an article or editorial about this exact phenomenon. To summarize the article, your fuel gauge is purposely calculated to read more slowly the first half of the way down, according to the author. Additionally, I know the Fit manual states that even when your gauge hits "E" there's still some fuel in the tank. It certainly doesn't seem linear. I'm still trying to burn off my first tank so far so I'll see how future fill-ups go.

 

dunno... right at the 1/2 mark, is about 5 gallons (us). I've always noticed that when you start the car up, the needle is where it should be... but if you drive a long distance, the needle moves slowly. Just like Gordio mentioned above. But I do have to say that this new honda is a lot better about the drifting needle. My '93 accord was about 1/3 tank of gas left read as being 1/2 filled.

 

I top off my tank at each fill. I'm usually around 110 miles before the needle moves off of F. I'm around 220-250 miles at 1/2. I usually fill around 360 miles on the tank, although I have surpassed 400 miles on a tank several times.

 

Wow... seems my car drinks to much gasoline than the others...

 

You for serious? Thats insane MPG!!!

 

MPG sucks! I'm averaging ~30mpg since new. However, for whatever reason, I can put about 12 gallons in my car when the fuel light comes on. I've put 12.6 gallons in it before, and the least that I have EVER put in it has been 11.3 gallons. Maybe they put a rubber tank in mine???

Go figure!!

My best tank has been 34.7 (I think...)

YMMV!!

 

David, yours is an automatic, no?

I just totaled up 13,000 miles of fill ups on mine (base five speed), worst was around 30, best 42, average for all since April is 36.5 mpg.

My gas light comes in at around 9 gal, I have never got more than nine gallons in. The gauge has a mind of its own and mine moves the same. Once you get to 1/2 a tank, I think you can actually se it move!

 

I guess I was going by the tank. 400 miles on one tank sounds damn good to me!! My Mx6 got a best of 217 miles tonight. I could have kept going but the needle seemed low; however the fuel light didnt come on. I ended up putting in 10.4 gallons. I normally put in 12-12.5 gallons.

I use to get 205 miles to the tank, I put nitrogen in my tires a few days ago. Made a big difference!!
All of you with bad MPG, nitrogen the tires. Youll be pleased.

 

it was 253 miles than the fuel light goes on yesterday... What all u guys think?

Can u show me the comparison for the MPG before and after Nitrogen? Thanks...

 

Or better yet, tell us how nitrogen actually improves MPG?

 

Well, I really dont know. But since I put it in my tires (fully drained and refilled) my car rides smoother, handles better, and I have more miles per tank.

I drive my car the same every tank. Like I said before I usually would get 205 miles to the tank. Then Id fill my car up with the normal 12-12.5gal. Last night I only put in 10.4 gallons and I was at 217miles. I could have drove way more!!
The nitrogen had to have something to do with it. Only thing Ive done to my car is rotate my tires and add nitrogen.

 

Gordio said it right: Gas gauges in cars are NOT linear. It's some sort of psychological thing... I remember hearing about some domestic car back in the 60s or 70s that DID use a linear gauge... then people complained that it burned gas too fast, and the manufacturer went back to a non-linear gauge.

 

Another thread here addressed "topping off the tank." Not that we haven't all done this at one time or another, but I recall several members urging others NOT to top off, as it would eventually damage the vapor recovery system (??) or something like that. When you "top off" the tank you are actually over-filling it, which can have implications to your vehicle. (I think the vapor recovery thing is an air pollution prevention deal that will become mandatory on cars as we continue to pour pollutants into the air. Here in Central TX we are beginning to suffer the consequences of air pollution with more expensive emissions tests and tougher standards etc.)

I really think that the E and F behind your gas needle should not be taken literally, or relied on too much. Myself, I use the tripmeter always, and I fill before I hit empty. I drive gently and consistently get 38-42 mpg on my base MT. I usually fill before I have driven 350 miles on a tank, and have never put in more than 8.75 gallons at a time. I do not top off but set the pump handle to the slowest feed and when it cuts off I am done filling.

I'm trying to treat this car right as I want it to perform as long as my last one did (20 years for me, and I just sold it last wk to some folks who intend to keep it for the rest of its natural life).

 

Nitrogen does not expand and contract the way air does when it gets hot or cold.

Basically, in your tires, you have air. When your tires get hot, the air inside gets hot and expands. Your tire pressure increases. The opposite happens when your tires get cold.

This fluctuation in tire pressure affects rolling resistance, which affects your fuel economy.

 

If you are concerned about the reliability of your gas gauge, you might want to consider bringing to the dealer since everything is under warranty.

 

Atmospheric air is already approx 75-80% nitrogen. When plugged into the ideal gas law, the per centage of expansion difference with the balance of oxygen and other gasses is minimal, nothing we would notice.

Nitrogen in tires has been a gimmic for years, I am surprised it has come back again.
