Entering the final stretch

Re: Entering the final stretch
Not necessarily.
If you stopped pumping at the first click you could have added much more if you kept squeezing the pump handle more.
I think people have reported getting over 1 gallon more into the tank.
So the big question is, how much is left after the bars disappear and how much is left ABOVE the first click of the pump.
I really wish I knew both of these with certainty.

These are the amounts from the first click to all the way topped off:
1.963 gallons
1.785 gallons
1.895 gallons
1.927 gallons
1.8923 gallons (average)
Of course, the largest part of this variation comes from where the pump shuts off for the first time.
As for how much gas is left after the first pip, I am pretty confident it is more than 1.3 gallons.
I just pumped in a total of 13.727 gallons this morning.

How can this be?
Honda says that tanks of our 2006 HCH2s hold only 12.3 gallons.

Re: Entering the final stretch
I believe that they report the capacity from fist click shutoff down to empty. I topped off this morning.

Re: Entering the final stretch
That's if I go till I run out of gas.
If I had topped it off:
I would have added the average of:
1.963 gallons
1.785 gallons
1.895 gallons
1.927 gallons
which is 1.8925
1.89 + 12.3 = 14.19
71 x 14.19 = 1007 miles.
Maybe higher if you could go 40 MPH for the whole tank of flat roads.

Re: Entering the final stretch
Mr. Kite, thanks a bizillion for that 13.7 number -- you rock. I've been very curious what the reserve capacity and top-off capacity on my 13.2 gallon tank might be. I always calculate my own range based strictly on 13.0 gal. It's nice to know there might be nearly an entire gallon beyond that (I always top off to visible fuel in the filler neck).
By the way, the range you show of 1.8 to 2 gal beyond first click-off matches my experience exactly. I've gotten as much as 2, usually get somewhere between 1.8 and 1.9.

Re: Entering the final stretch
Well, I was excited today because I finally joined the 600 mile club after my 7th tank. But after seeing this thread, I am feeling very low on the totem pole . Anyway, I had 50mpg. The last fuel light went out at about 490 miles, and when I filled up at 608, I put in 11.8 gal so I had about 1/2 gal left. With you getting 70mpg, you should squeeze out at least 150-200 miles after the last fuel light!
Sounds like you went 118miles after E or about 2 gallons beyond E. So 11.8-2 is about 9.8 gallons at E. Or about 2.5 gallons left at E.

Re: Entering the final stretch
Thanks Kenny - now at least I might be able to take nice pictures like you - wont touch your typical FE though....
I also use CC on my highway segments, getting up to 61mpg for daily commute averaging 55 and 65mpg (limits) on the two highway sections. I may take the 65 down to 60 as this may allow me 1) stay at similar speeds to many trucks, 2) take FE up on that segment and 3) cost me ~1 minute on that 10 minute segment.
I was after the speed where peak mpg happens not for freeways, but for other rural segments or even urban segments. Maybe getting to and running at this target speed is worth it if you dont have to slow/stop for say 1+ miles down the road.
I suppose you can estimate this target speed if you run up/back same stretch of road enough to get a meaningful average mpg versus the noise.
Thanks again.

Re: Entering the final stretch
Yeah, I was doing that math as well. I'm going to give it a try.
So far, I'm at at 134.7 mpg after 5.0 miles. (The gas station where I filled up this morning was about 220ft higher than my house). 995 more miles to go. So far this summer, I'm usually able to break 70 mpg on days when I'm just going to work and back along with daycare stops. I can often do much better if I have some favorable errands to run.

Re: Entering the final stretch
Most efficient speed is very difficult to calculate in the HCH 2. Usually, it's the speed at which a car uses lowest rpm in the highest gear. But since the CVT constantly adjusts, it's tough to tell.
A patient owner could find a long stretch of road and try to find the m.e.s., but so many variables affect mpg that it would be almost impossible.
Even the flattest stretch of road has slight uphill and downhill inclines, and that affects mpg noticeably. Also, a slight gust of wind will drop mpg momentarily. So using the mpg meter for specific speeds over short distances is unscientific.
If I had to guess, I'd say the HCH's most efficient speed is 45 mph. If we could all stick to that maximum, we'd get 60 mpg, and those who could sacrifice air conditioning would get 70, like Kenny. He provides a great real-world example of what the Civic Hybrid can accomplish.
Unfortunately, Texas is not part of the real world. Driving 48 mph with no a/c here would leave you dead from one of three causes:
1. heat stroke
2. getting rear-ended by a semi going 70 mph
3. getting shot by a pickup driver going 80 mph
I'm not kidding.
So I'll have to stick with 65 mph and liberal use of refrigerated air. I can still get 50 mpg doing that -- halfway through the current tank and showing a solid 49.9 so far. I'll post the pics when I hit 600 miles.
