03 Civic Si fill up issue.

I've noticed when filling my car that the "filled" shutoff triggers way to
early. Now I know that you are not supposed to top off you tank but seeing
I
can fit another 3 gallons into the tank after this starts (very slowly) it
certainly does not seem correct to me. More than doubles my fill up time
and
is pretty annoying.

Mr. Trap,

It only takes longer to fill it if you disobey the terms of your
warranty and overfill it intentionally. The people are content to do
what the book says are half way home while you're goofing around.

If you won't believe the book, call the fire department (or the EPA) and
see if they think Honda is just pulling your chain for writing such a
lame thing in their owner's manual. :-(

Curley, do you intend to say that the shutoff *should* happen when the
tank is 3 gallons or more from being full, or am I misunderstanding
something?

Dave,

As I understand it, the reason you need so much 'headroom' in the tank
is mostly expansion. Gas is stored underground and comes out pretty
cold. On a HOT day, it will expand at a great rate, and if you park it
on even a slight angle, it will 'burp' into the evap. canister, then
start overflowing wherever it can. This is clearly a fire hazard, not to
mention an unsound environmental practice.

Gas runs down the street, or starts to pour down the nearest manhole
cover. Add a smoker walking by while lighting up, and somebody gets to
be on the evening news.

I think roll-over accidents are part of the equation too, but I don't
know anything about that part.

I don't think these people writing the manuals are just trying to spoil
our fun, really. :-(

This is true, except on a cold day, when the product coming out of the
ground is actually warmer than the above ground temperature.

 

Well, the way you say it here sounds reasonable - although I try not to
let that get in the way of a good argument. ;^) I think that if my
tank did that, there'd be something wrong, even though I've never put
more than 15 gallons in ('03 Accord, 17 gal tank I believe).

The process you describe seems to me to be certainly possible, but not
much more likely than a car exploding in flames due to a collision
(outside of the movies). I recall that this past year, there has been
an increased awareness of the potential for static to cause disasters at
fillup. That seems to me to be somewhat more likely, although still a
remarkably small chance. I suppose any chance at all is enough to get
the lawyers into the engineering department, but I do think we can go
too far protecting ourselves from ourselves.

Give me a break! The car has a 13.2 gallon gas tank, yet after driving on E
(low fuel warning light on for > 40 miles, needle pegged at E) a fill up
shuts
off at 8 gallons. Now assuming I still have a gallon or so (lets be
generous... 2 gallons) that means I can never put more than 10 gallons in my
tank). Now don't lecture me on "overfilling" a 13.2 gallon gas tank with 10
gallons. Since when can you add another 3 gallons into a tank and not have
if
overflow I think your are mistaken. And for the record nary a drop as
spilled
from a single fill up.

So who else has a 02 Civic Si here and can put more than 8 gallons of gas
into
it?

 

If you fill your gas tank all the way to the filler neck on a regular basis
you will clog your fuel filter and destroy your fuel pump.

When you overfill there is gas flowing into the charcoal canister (not just
fumes). The gas is then sucked back into the tank under normal operation.
The charcoal canister is full of dust and other deposits (air continuously
flows through the canister) which are dissolved in the gas and introduced to
your fuel tank.

3 gallons out is a little excessive, especially on a car that only holds 13
gallons. Does this happen at every gas station or only at particular ones.
I've noticed that some gas pumps tends to stop a little earlier than others.
I too like to add more gas into my tank after it stops.

 

I agree with Leon; the manuals for my 2000 Civic AND 2003 Odyssey both
indicate that filling the fuel tank should cease when the service station
nozzle auto stops; I imagine that this is assuming no faulty equipment is in
use at the gas station.
I believe Honda recommends this for the fuel filter/ fuel pump observations
Leon noted.

worry- perhaps you'll be a Honda someday!"

 

the "lame thing" is actully that door thing just inside the and under the
fuel cap. In Europe, cars don't ahve those, and you can easily fill to the
brim (I used to do it 3 times a week, for 7 years, and never had a drop
spill out. well, maybe a little. thats with me filling right to the brim,
and even rocking the car as well (back when we had the fuel strikes in the
UK in the summer of 01 you got all you could, when you could) to get any air
bubbles out that were there. It gets just as hot int he UK as the Us as
well, this past summer London was as hot, if not hotter, than here in
Georgia most days.

I've no idea what that flap/trap thing is for either. Its not needed to make
the pump shut off (european fuel pumps shut off too, its works on a
float-switch, I believe).

Supposedly overfilling can let fuel get into the vapor return hose and flood the
charcoal canister. This causes some problems until the canister purges all the
raw fuel.
