I have a 2008 Civic Hybrid. I was averaging 47mpg and 50+ on the highway.
Suddenly, my mileage dropped to the 39-40 range. I talked to the dealer about it and they had no clue. I changed several gas brands to no avail.
So, I did a little test. I turned off the air conditioner for two to three days (that's torture in Florida in the summer) and sure enough the mileage started to climb.
I also play golf once a week, sometimes twice, so I took my golf clubs out of the trunk and put them in the garage.
Sure enough, my mileage climbed back to the 47 level with no A\C and no extra weight in the trunk.
So, if you live in a hot climate, try the A\C trick, take extra weight out of the trunk and overinflate the tires by 2 or 3 lbs. each.
During the hot days I still use the A\C and suffer the fewer miles.
Can't wait for fall and the cooler weather to get back to normal.

As I mentioned before on this thread, I wasn't getting the mileage I expected after buying a 2009 Honda Civic Hybrid on April 1, 2009. As I mentioned then, please take your Honda Civic Hybrid to any Honda Dealer and ask for a Fuel Consumption Test. They may have to keep your car for several days to do this.
I have never gotten better than 39.9 miles per gallon driving in all conditions. I do have the A/C on a lot as we have been in the 100's the last of August and the first two weeks in September. This is sometimes with another passenger in the car, and sometimes with some weight in the trunk. I have to think that the ideal conditions to get MPG in the high 40's to 50 would be single driver, no A/C on, no extra weight in car, and factory recommended tires, (in the Owner's Manual), and reasonbly conservative driving habits. In this condition if you don't get at least 40 to 45 mpg, something may be wrong with your Honda Civic Hybrid. If you don't follow exactly what the owner's manual calls out in tires, that could make a difference. If you ignore the low tire pressure indicator, this can bite you also.
I am going on a long trip this week-end and will have a chance to really check out highway mileage. Of course I will have another passenger, some luggage, and probably the A/C on. I think the EPA ratings on MPG should get real, and define what real MPG are with the conditions I just described. Otherwise, the MPG on the dealer's window stickers are always going to be high and GUESSING at what the REAL MPG are in average driving conditions/situations.

Living in the colder winter climates,people that own Civic Hybrids are now more than likely starting to experience the annual lose of between 7-10 Mpg!! This has been my dilema since the 08'/ 09 winter when I first started seeing this major loss of fuel economy. When I went to my dealership, they had no solutions or explanations.When I called Honda of America[corporate headquarters] they couldn't come with any answers either. Earlier this summer, I saw a report on the Weather Channel about hybrids & winter fuel losses due to the battery pack being cold & not functioning efficiently as when warm.This was the only report/explanation I have ever seen about this MAJOR problem w/hybrid batteries. Anyone else experiencing this winter loss of Mpg?

Not sure about the cold weather affecting the battery pack charge life. It is possible that it takes longer to charge. I would think that Honda could give you the specs. on the optimum battery temp. producing the best battery charge and discharge rate. On my Calif. 800 mile round trip, I averaged 42 mpg, w/passenger, A/C on, luggage in trunk. Driving around 200 miles in town and around 200 miles hwy. I average 37 mpg. Most auto mags, and consumer reports indicate this is about what to expect from the Honda Civic Hybrid, (37 mpg) average.
 
If anyone gets abouve 37 mpg, consider yourself ahead of the GAME!
