Over 25,000 miles on a 2007 HCH, I have averaged 39 miles per gallon. Better in summer, worse in winter but 39 miles per gallon overall.

To: Jonathann,
Now that is what I would expect, at least something close to 42mpg, which are Honda's and the Gov's. average fuel consumption testing numbers. For 25,000 miles, that should cover a large amount of driving conditions, city, hwy., weather, etc. Thanks for the input.

HCH gas mileage by davem7

I am currently on my 3rd HCH, this being a 2008 with Sat Nav/XM Radio. Have nearly 15,000 miles, approx. 6000 of which were put on this June and July: average is 55MPG I'm fortunate in that my girl friend has a Prius and we rotate the cars, so that the HCH sees most of the highway and the Prius most of the city. We are both hypermiler aspirants, but avoid the dangerous techniques like drafting. I keep all four HCH tires inflated to 50psi and I'm convinced it makes a favorable difference. One difference i've noticed between the hybrid systems in the HCH & Prius, is that the former takes much longer, 5-10 minutes on the average, to activate than on the Prius in cold (below freezing ) weather , The Prius usually activates in 3 minutes or less. l If your keep your HCH in a garage in cold weather, I would suggest a block heater, this narrows the warm up time comparable to the Prius.

Well, I finally figured out the problem with the sudden drop in mpg for my 2008 HCH from a steady 47 to 41. The mileage dropped even farther, to 39.2. As I mentioned I was getting a steady 47 mpg local driving. Even the dealer couldn't give me a reason for the drop from 47 to 39. I tried different brands of gas. Same problem. My curiosity then turned to the air conditioner. I live in Florida. Last Wednesday I filled up my 2008 HCH, opened the windows and left off the air conditioner. I drove for three days without the AC (try that in Florida in the summer). Sure enough, my mileage again jumped up to 47 mpg. Can't wait for the return of fall.

2006 Gas mileage falling. Why? by nilesboy

I bought a 2006 Civic Hybrid new in 2006. I have 33,500 miles on the car. I started out getting 45 to 47 MPG city/highway driving for the first 2 years.
On a trip from Fl. to W.Va. I even got 50 mpg.
In January 2009 (after buying new tires) I began to get 38 mpg or less city/hwy. It keeps going down consistantly. Today I checked my mileage and it was 32 mpg city/hwy. Anyone out there have any answers? I use the same gas (sunoko, hess,BP, citgo, etc.)

Mileage continues to go down by nilesboy

I bought a new (06) civic hybrid in Jan. 2006, I have 35,000 miles on the car. Started out getting 47 mpg average for the first 2 years. In Jan. 2009 after putting on new expensive tires the mpg went down to 38 mpg. Today Sept. 15th, 2009 I checked after fillup and it was 35 mpg. I am a careful driver with no jack rabbit starts etc. Any suggestions? Could it be the Hybrid Battery? Please give me your opinion.

I am not an expert by any means, but I understand that tires make a big difference. Just that they are "expensive" doesn't mean anything in terms of gas mileage. Too much tread equals decreased gas mileage??? again, sorry not an expert.

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.
