How far have you gone on the low fuel light? - Click HERE for Original Thread
Sportymonk
And how much did you put in?

Was driving to Raleigh the other day and knew i could get gas for 2.74.9 just outside Raleigh when it was 2.88.9 where I live. Hhhmm, low fuel light not on and about an 1/8th of a tank, ought to be able to make it.

Low fuel light came on; OK about 2 gallons at about 20 mph on four lane highway, going about 70 - 74mpg on cruise; ought to be able to make 40 miles.

Dum de dum de dum and at starting to get nervous, little further than I thought, been 22 miles since light came on. Dum de dum, been 32 miles. Sign up ahead says my exit is 2 more miles and I've been 35 miles, that makes 37, sweating.

Pulled in gas station with 39 miles since low fuel light. Pump cut off at 19,81 gallons. :eek: Rounded it off at 20.21 gallons. Decided to see what 05 fuel tank capacity is. 20.34 :eek:

Haven't cut it that close since traveling from Austin TX to Arizona in my wife's old Camaro and she insisted I get some gas in the middle of nowhere. Paid an outrageous amount for 5 gallons. When I got to Fort Stockton Texas I put 20.5 gallons in a 20 gallon tank. Have never heard the end of that one.

Interesting twist on a related thread.

Has this turned into another $^#@%* thread on "What are you paying for gas?"
charliekhonda
I travel 35 miles each way to get to work. The most I dared to go with the light on has been 30 miles. Up here in Boston we are still @ 2.89 a gallon.
ED27
Sportymonk....your story reminded me of the Seinfeld episode when Kramer test drove the Saab. :D

The closest I've cut it was about 20 miles after the light came on. IIRC, I ended up filling up with over 18 gallons.
xkalibur_gt
The lowest price i have when enroute to calgary (aug 20) (took the US H-ways) is (bronze) $2.55 /gallon , $2.89 (silver) @ minesota.

I just put 19 gallons in it the other day. I felt a little nervous too!

Come to Des Moines, Iowa if you want cheap gas. It's been steadily dropping and is at $2.46 right now.

I have always understood that topping off your fuel tank is not recommended. You may not get all the gas you paid for plus an environmental issue. I did a few searches and have attached one of those here.

Is that for the ethanol blend? Over the summer we were up in IA seeing our parents and their ethanol 89 octane was cheaper than 87 regular.

Of course here in TX, ethanol is evil because oil is king.;)
Art
My wifes great at that. I'm sweating, and she's driving. As soon as my light goes on I fill up, if not just before.

Here in Cedar Rapids, IA, it's gotten down to $2.51 for the mid-grade. I love Texas, but at those prices I'll replace a little middle eastern oil with a little middle western corn any day!

(Of course, since I'm subsidizing it with my tax dollars, I'd better take advantage...)

40 miles after the light came on and when I filled it up, I have about 3/4 a gallon left. That was the closest I ever let it go (usually fill up right after the light is on).
Sportymonk
Sounds like 40 miles on the highway is about it. I had about half q gallon and you had about 3/4 so allowing that not all be picked on on hills etc, I wouldn't push it beyond 40.
N_Jay
I get an easy 45 or more.

Light gives you a solid 3 G to empty, and that is not DRY.

Highway MPG is 20+ (Usually 22 or so, but depends on lots of factors)

I would say that even if you counted on only 18, that would give you 54 miles.

This is for flatland, hills can move the gas to the wrong spot and cost you a few miles.
Nathan
I've done 50 miles twice and 60 once. But I also baby my 2WD for 20 avg city / ~25 avg hwy.

The book says the tank has 2.8 gallons when the light turns on. That seems pretty accurate.
bright06Pilot
I've gone 40 and I thought that I was pushing it. Guess it depends on how you drive that last bit of gas. I am averaging close to 15 mpg mostly city stop-n-go traffic.
stanley cup
ONLY 5 MILES!!

Note to self:
Never hop in the wife's 06 Pilot and start driving without knowing how long (days?, weeks?) the low fuel light has been lit.

She replied "oh I think the light just came on before I pulled into the driveway last night."

Yep, about 5 miles later I was walking to get gas. :3:

How many gallons did it take to fill up from dry?
stanley cup
I walked to a friends house and bummed whatever gas he had in his shed for his mower. I put that in and the pilot fired right up. I don't know how much I put in maybe around 3/4 gallon. Then I put in just over 20 gal. into it at the gas station.

At that moment. I wasn't thinking too much about the specific quantity of fuel, but how I was going to peacefully explain to my wife that she was an idiot.

I guess it was my own fault. I should've learned my lesson after she ran her last car out of coolant and melted the motor into a $1500 boat anchor while sitting in the drive thru of a bank. She made a lot of new friends that day. :D

Nice to know I'm not the only one who mysteriously "gets" to drive my wife's car only to find out that the gas gauge was below E.

Just remember.....those wives are sneaky creatures. ;)

If you even thought for a minute that there was a way to explain it, YOU are the idiot!:4: :4: :4:
(Either that or you have not been married very long!)
bright06Pilot
haha I'll have to second that
stanley cup
Yes, your Honor, I am guilty of being an idiot. I accept full responsibility for trusting my wife. I promise, it will never happen again.
nyhunter77
I'm with N Jay on the amount ... u can go more than 45 in the city.

I live in the city and when the light comes on i hit the reset button on one of the counters and someone here once said u have about 4 gallons when the light comes on. That being the theory I always take it to at least 40 more miles and then fill up.

since i get about 15 to 17 mpg in the city i figure i have gas left but why tempt fate?

This one confuses me. So 100% of hte gas gets to your tank until it cuts off, and after that it is just filling the hose? Wouldn't the hose fill up regardless? Am I missing something here?
:confused:

Topping up is not recommended because you are much more likely to "accidentally" spill some gas.

In addition, you often force gas into the evaporate control system, disabling or even ruining components of the system.

Was the $2.52 savings realy worth the worry?

I have found that the resettable "B" odometer is great for tracking this. As soon as I notice the light come on, I reset "B" to zero and leave it displayed.

I'm drive almost all city and I get about 15.5 MPG average. So, I figured I could get 30 miles once the light comes on.

I wasn't aware it still had 2.8 gallons in there. That explains why today, I had driven 32 miles and put in 18.5 gallons. I think the '03 has a 19.6 gallon tank.

Now I can start going 45 miles before I fill up! :) (I'm gonna run out of gas one day...)

I don't know about the Honda's EFI, but most EFI systems use a submerged tank-mounted fuel pump that suffers greatly when run "exposed" [above the low fuel level].
I have been told by several factory trained mechanics that this is very bad for the pump due to lack of cooling and cavitation [from sloshing].
My Wife also had a premature failure of the fuel pump on her Van, which resulted in a tow-in and $1500.00 which the dealership attributed to Her always-empty fuel tank.

I had a long talk with an engineer from Bosch on this topic when my company car (Ford) had its third fuel pump go out.

He said that it was not true, and that as long as the pump picks up any fuel it has all the colling and lubrication it needs.

He thought the rumor persisted because a failing pump will fail when it is doing the most work with a near empty tank.


I find "mechanics", to be very good sources of repair information, and usually poor sources of engineering information.
jrinjax
That is interesting, this was a Ford also.
Thanks,

I haven't ever monitored the number of miles I've gone after the low fuel light came on, but I do know that there have been at least two occasions where we've put in more gas than what the owner's manuals states the gas tank can hold.

My guess is that gas pumps are not very accurate when it comes to measuring how much gas is being pumped. I've often thought about calling the 1-800 number on the gas pump and contact Weights and Measures to have them come out and check out the pumps.
jrinjax
There might not be a problem with the gas dispenser calibration, it could be the maximum usable fuel that is listed in the Honda spec. instead of the total fuel that includes non-usable spaces/expansion areas. It is also very hard to hold exact dimensions on a non-cylindrical tank like the Honda's. We know the tank is somewhat flexible by all of the noise complaints of it "oil canning".


I do feel better about the low fuel level not shortening the fuel pump life since my Wife occasionally repeats prior mistakes.

Hi Guys - I'm a little concerned about my fuel gauge behavior. I had the fuel light go on last week, but the gauge was still reading about 1/8 tank full. I filled up 19 gallons!

After I fill up, the gauge doesn't move off full for at least 80 miles. I filled up a partial tank this weekend - gauge read about 3/4 full, yet I pumped in 9 gallons.

Are you folks seeing accurate fuel gauge readings? Meaning if tank is 1/2 full, it should take about 10 gallons to fill?

Thanks!

The gas gauge should not be used to measure how much gas you have in your tank... at least not to the gallon. For example, we've gone 150 miles using only a 1/4 tank, but that doesn't mean we'll get 600 miles on the entire tank.

I wouldn't be too concerned about filling up 19 gallons when you have 1/8th of a tank showing on the gauge.

However, the gauge not moving to full until after 80 miles is a bit odd. Unfortunately, any work to the gas gauge requires the gas tank to be dropped... not exactly a cheap fix.
jrinjax
I was disappointed that the Pilot did not have an option for a Floscan type trip meter. I wonder if the ECM has the map information/math output in it to pick up the injector flow rates like the Accuras do.

Running on low fuel level is dangerous to the health of your car.

The reason is, the electric fuel pump uses the fuel to cool itself. First of all, your fuel pump need to work extra hard to maintain fuel line pressure especially when you going up and down any slope. The pump might suck in some air once in a while (when bumpy with low fuel level) and this is bad to the pump because during the air gap time, the fuel pump cannot cool itself using the fuel it pumps. This will bring premature failure of electric fuel pumps.

I used to do this because gasoline used to be 50 cents cheaper in Massachusetts than Connecticut soI run on low fuel in order to get back to Mass. to save a few bucks.

The Car Talks guys said the same thing on the radio once about premature fuel pump failure.

I just installed the Scangauge II in my Wife's Pilot to make up for the disabled trip computer in the NAVI system. The Scangauge is a pretty nifty little device for only $139.00. It gives me MPG, average MPG, fuel remaining, speed, RPM, coolant temp and any diagnostic codes [along with resetting them]. The installation/setup takes 15 minutes [mostly reading the manual].
If She can remember to reset it when She fills up it will let Her know what the safety margin is...
I even have a Floscan on my Boat with a fuel Totalizer [you get spoiled when you have one in the aircraft you are flying].

Where did you find it for that price? The lowest I've found so far is $159.

I have over 157k miles on my Integra and have never had a fuel pump failure (knock on wood). In most cases I do not fill up the gas tank until the gas gauge is below the "Empty" line. :confused:
jrinjax
Samster,
I went back and looked at the invoice for the Scantool II and found that I was wrong, I paid $169.00 for it.

It is really a intuitive little device that really displays a lot of information such as; Fuel burn, gas mileage, average gas mileage, MAPressure, intake air temp, Coolant temp, open loop/closed loop control, ignition timing, RPM, throttle position, vehicle speed, plus all of the trip computer data.

I also found it interesting to watch the ignition timing, when you back completely off the throttle, the timing retards to ATDC to use the engine for braking [grade control logic?]. I always thought it would go way advanced instead.

The Scantool will also read/reset the OBD codes [check engine light] too.

I mounted mine on top of my Wife's steering column [they come with a self adhesive velcro mount] and adjusted the color of its display to match the color of the radio controls.
