Found tghis site via a Yahoo! infobox, and have signed up.
Wer got a 1994 Honda Civic Hybrid (manual transmission) Aug. 1, 2004, after our previous Honda Civic Hatchback was totaled in a head-on (AIRBAGS WORK!!) by a Flatlander admiring the scenery on our narrow two-lane road. We log each tank on "Trip A", and mileage between servicings on "Trip B". We use the HCH conservaitvely, adhering to CA 55 mph on local roads, and 65 on occasional freeway runs. Normal usage is one trip a week over a 1200-ft. pass on a narrow and winding 2-lane road (100 ft. elevation change both sides) for shopping in the nearest city (Ukiah, CA). Coming up on 3 yrs / 23,000 mi. to date, TM "A" reads 47.1 mpg, TM "B" 43.5, and we can just top 50 for local runs in Anderson Valley. All verified from our mileage vs. gas purchase log. (Previous 1997 Honda Civic Hatchback - manual - was 37 - 39 mpg in the same service.)
I am a fairly experienced driver, sensitive to engine performance vs. gear choice, and "gear down" approaching stops; wife is less sensitive to the mechanics, uses the brakes more, but usually comes out about the same mileage per trip. We are TOTALLY satisfied with the HCH, and find it NO different to drive than our 1997 hatchback, with the bonus of more rear seat room and access, vs. slightly less load space. Our ONLY gripe is the lack of a rear window washer / wiper system. Oh, yes, local dealer service has been excellent!
Just wanted to throw this into the pot, from nearly three years' usage. So, HOWCUM Consumers Report gets only mid-to-high 30's MPG???

#302 of 540 Hybrid Mileage for the HCH II
May 14, 2007 (7:35 pm)
Doug & Bev Elliot,
Great job with your Hybrid Civic. I can tell you how they only got high 30's for FE. I get from 37-40 MPG daily because I drive only 10 miles to work on the interstate at speeds of 70-80 MPH. No long distance to increase the FE. So can the HCH II that I own do better than the high 30's to 40 MPG ??? Yes
I have gotten as much as 66.7 MPG on a trip at 55 MPH and setting the Cruise Control and No A/C.
It just depends on the situation.
Glad you are enjoying your Hybrid.
I have mine for over a year now and driven it like 10,000 Miles so far. It has the Nav. and X/M Sat. Radio. Nice Hybrid and I love it still and glad I bought it.
#303 of 540 2007 Honda Civic Hybrid mileage
May 15, 2007 (9:10 am)
I am getting 32.8 average MPG, just have under 1000 miles on it. I drive 7 miles to work and use it around town, not much freeway driving. So far it seems to be not getting the 49 city mpg. I am not using A/C, mostly flat driving. My top MPG was 39.7 when I did a freeway trip.
#304 of 540 how much does running a/c effect mpg?
May 24, 2007 (7:18 am)
I usually run my a/c as cold as it will go, with the blower on low. I'm wondering if its less taxing on the compressor(and therefor on the engine) to run the temp not quite so cold, but the blower a little higher. Does anyone know if this will help conserve fuel.

Just my general experience and observation... if the A/C compressor is running, the mileage on any vehicle is going to take a hit. I've never looked closely at using higher temperature settings to see if that would make a difference or not. My gut is telling me it won't because the compressor is still using up energy to run.
Might be time for a little experiment!

Why would auto manufacturers give you the ability to adjust the temperature, either electronically or via manual rheostat, if they wanted you to keep the compressor running 100% of the time? Same thing for your home or office. That's why there are A/C thermostats in those locations.
It is surely less taxing on the amount of fuel consumed and on our environment to only have the compressor running when absolutely necessary. The more load on the compressor, the more load on the engine, the more fuel required.

Ah, one of my favorite peeves about auto A/C. The manufacturers want to give exact control over the temperature - thus, if you raise the temp, the compressor still runs, but it adds hot air to the mix. It ensures that the person gets just the right temperature, but it is also just stupid. My 1973 AMC Gremlin adjusted the temperature by cycling the compressor, which saved a lot of gas. They don't even offer the option to do so these days...
30 years of progress????

I think the auto a/c compressor does cycle on and off. You could observe this with the vehicle at idle and the hood open.
If you have the air handler set on recirculate, then it shouldn't be bringing in outside hot air, but depending on the design it is possible that the individual temp settings require that some of the air is passed through the heater core to give warmer air to one side.
The way to avoid this inefficiency would be to operate the a/c in the manual mode rather than thermostat mode and to have both temp settings on the lowest temp and use the lowest fan setting which is tolerable for the person who likes the temp the highest.

Replaced the spaceship wheels with a set of the SI wheels and I'm getting a decent 42MPG
