Well quit confusing me...I have enough trouble as it is :)

Peace,

To be more precise I have measured left over from the gallon bottle:
it was 3 1/2 cups. So my honda fits at least 3 quarts and 1/2 cup.
The reservoir was not completelly dry when I pour the new fluid there.

Really? Are you sure? How much is "much more" would you estimate?

That is funny, because I could fit much more than 2.5L to my 2004 coupe (US).
My user manual also lists 2.6 US quarts / 2.5 liter. What is going on ?

The Owner's Manual for my 2003 Accord Sedan lists the windshield washer
reservoir's capacity as 2.5l for the US model and 4.5l for the Canadian
model. Does anyone know if the Canadian reservoir would fit a US model?

my 2008 civic LX (canadian version) has heated mirrors and a washer jug that
accomodates 4L (just over 1 gallon) no problem.

My 98 civic also takes over a gallon of washer fluid.

I wonder how much savings honda got not doing these things.
I got EX-L trim, you would expect it to be fully loaded - such a wrong idea.

Maybe it's

Yeah, and you guys (and girls) get the heated mirrors.  We don't.  Even
my old '85 Scirocco had heated mirrors, but not this new Civic.  Grr....

My '01 coupe has a warning light, and when it comes on I can put an entire
jug of washer fluid in and still have room left for more... Maybe it's
because I'm in Canada (the frozen white north and all), or maybe the design
of the '04 required a smaller reservoir.

I can see you are an old fashioned guy who likes to spend time
with his car and keep the garage full of funny bottles... :-)

Good design in my opinion would be low fluid warning light
on the dashboard and reservoir big enough to hold FULL bottle
when the warning ligth comes on to minimalise required mainenance.

The only warning I get from my accord is that the stream of
water is weaker, but then I have 2-3 more attempts and it is dry.
Even then it does not hold the full bottle, which is sad... :-)

Don't get me wrong, but I am comparing this accord to my old
1995 camry, which it happens had the reservoid big enought
to hold the full gallon of fluid in one big gulp.

If your preferred method is to suck the reservoir absolutely dry before
refilling it, thus risking being without washer fluid at some point when you
really need it, then yes, I suppose you might consider it a bad design.

If, on the other hand, you do what a lot of people do and add fluid to the
reservoir periodically before it's completely dry, and then put the bottle
back in the garage for next time, then it really doesn't much matter how big
either the reservoir or the bottle is, does it?

For the second time I needed to refil washer fluid in
my 2004 accord coupe. I got the 1 gallon jug from the
store when the washer nozzles stopped delivering fluid.
Poured the bottle but before the bottle was empty
the container in the car was full and overflowing.
2-3 inches of the fluid left unused in the bottle.

Is this what you get? Or my pump is not sucking all
the fluid from the container?

Why would you design a car with a washer fluid
container just smaller than the widely available
container the fluid is sold in the stores?

Would you consider it as a bad design?
