2004 Honda Civic Hybrid, AT-PZEV, CVT
(Tank on AT-PZEVs only holds 11.9 gallons)
90% 53 MPH on freeway on cruise control.
Low fuel light just came on at 602.9 miles, so I could still go 60 to 100 miles more I think.

Hi Kenny:

___Great job on the tank! I looked at your last tank doc and did you fill her up with just 9.7 gallons? If so, you have almost 2.2 gallons left which is good for 125 + miles, not 60 – 100!

___Now, drive w/ load and use 53 mph as your target and see what happens. Buzz70 will be eagerly awaiting the results ;)

___Good Luck

Yes 9.7 gal filled it up.
I don't top it off though.
When the automatic gas nozzle thingy stops, that's it.
I don’t want to top it off since gas evaporates.

Also, I fill up when I have only one bar on the gauge.
I am afraid to go too dry.
Doesn't crap get sucked up into the fuel injection if you run too low?

I'm not sure I can really drive with the load.
My route to work does have several slight up and down inclines, but I really do not feel safe allowing the car to fall below about 53 MPH.
Which means I would be letting fall to 53 as the lowest at the top of the inclines.
That means I’d be going OVER 53 downhill, and that seems wasteful to me.

Also, my mileage is about 2 MPG worse since I changed my oil a week ago.
I measure my morning commute every day so I have a lot of data.
The change is not noise; the reduction in mileage is real.

I put in exactly 3.4 qts of Mobile a 0W-20.
When I check the oil in the morning (completely cold) it is hard to tell the oil level because the oil is so thin and clean, but it looks like it almost reaches the upper hole in the dipstick.
Maybe if I let a little oil out my mileage will improve.

62.4!?! Great job!

I just have to say again how much I love the look of the HCH gauges. The integration of the analog speedometer with the other digital readouts is very cool.

You're darn tootin' I'll be watchin'. I'm actually more interested in what mpg's you get for the whole tank, not how far you can go.

It's nice to see that you're at these mpgs early in your hybrid ownership. I've had mine 2 years, and just now I'm getting these figures. Does this mean the gas is different, I've just learned to drive it that efficiently, or dumb luck? I do have to wonder about the gas, because my mpgs jumped about 4-5 mpg over the last 2 months, and I have no idea why....

I think the only difference between mine and yours is 1) I have the manual transmission, and 2) I don't drive at 53 mph with cruise. As a matter of fact, I hardly ever use the cruise control, and when I am on the highway, I'm doing 65. Most of my high mpg tanks are going back and forth to work, which is in high traffic! Figure that one out.

By the way, Kenny, have you been putting the dash mpg's in your tank data? I think you're supposed to use the calculated value.

I don't top off my tank, either. Like you, on the first click, I stop.

Great job Kenny that's simply fantastic.
Good to know I'm not the only one who carries a camera in their car for dashboard photos! :lol:

Keep up the great work!

I fixed my entries in the database to reflect calculated at the pump and not on the dashboard MPGs.

FYI it made it an average of 3.4% lower.

That's still fantastic figures, Kenny. Congratulations, and keep up the good driving!!

I think part of the problem w/ the display versus calculated is the difference in the displays gallon and the gas stations gallon. The gas station's gallon can be 10% (or something close) off as far as acuracy. The display should be calibrated to a proper gallon.
Cheers,
Steven
