Running the heater shouldn't affect gas mileage but I suppose in cold weather the car would be set to run a little faster until it warms up. Not sure if these cars have automatic chokes. My car is kept in the garage.
 
But here is a tip I recently found about getting better gas mileage on these hybrids. Turn on the cruise control and don't turn it off. Use it every chance you get by setting it to the speed limit on the road you are driving, even in urban areas. Hit the set button every chance you get. Watch the assist go to work no matter what speed you are driving. Believe me, it works, and it will give you better than average mileage.
 
Currently my gas tank is down to a little under half full and when I checked the mileage on the dash last night I am averaging 50.2 in mostly non-highway driving. Prior to this trick, I was averaging 45 to 46.
 
I live in Florida and am anxious to see how this works in the hot weather because using the air conditioner does reduce mileage per gallon. In the hot weather I average around 41-44 because the AC runs constantly. Haven't noticed any change yet using the heater because I haven't run it in around 10 days when the last really cold spell came through (yes, it's gets pretty darn cold in Florida in the winder).

That last word should read winter, not winder.

First day: 42!!! And, it was on hills and in the cold and with lots of slow, fast traffic I have to adjust to.
 
The merrit in Connecticut is what it is: I can't do the super efficient driving without getting shot.
 
I'm real happy with 42! My old 2002 regular civic was getting 34 or lower.
 
And, I LOVE IT!!

Is it normal with a 2006 HCH to get 39 m.p.g. on the highway with rolling hills at 75 m.p.h.

That depends on air temp and tire pressure. I have noticed that my fuel efficiency is highest when the engine is running at 1100 to 1500 rpm. At 75mph the transmission has shifted out as far as it will go, and the rpms were probably around 2200-2500 rpm at 75mph. Plus the fact that the wind resistance against the car climbs greatly above 55 mph. So in other words, the HCH is great around town, best at a cruse of 35/45mph and begin to suck at higher speeds and heavy loads/ extra passengers.

Don't know if you saw one of my earlier posts but a trick I learned is to keep the cruise control ON at ALL TIMES. I use it every chance I get even in local driving. If I am on a road and the speed limit is 35 mph and it is pretty clear ahead, I hit the set or resume button. It does have a positive effect on gas mileage. My last fillup, Friday (and I check my mileage at every fillup) was 49 mpg for local driving, one of my best. Also, with a hybrid long trips do not necessarily mean better mileage. The most I could get on a trip on interstates is 50 mpg. But I always average 46 to 49 mpg local driving. That's without the AC on. With the AC constantly running I usually average in the 44-45 range. I also found I get much better mileage on the off-brand gasoline than I do on the name brand. I can't explain that.

I use that method except going up hills I take the cruise off.I f I don't the r.p.m.s go way up! Air pressure in tires is 44lbs. filled with nitrogen,air off windows up.Still 39 m.p.g. before it was 40-45.Something changed,I can't figure it out.

I'm going to slow it down to the slow lane 68m.p.h. and see what happens and report back in a couple of weeks.

#497 of 540 MPG - does it worsen with miles? by greenbook

Bought a used HCH 06 with 70K on it. Previous driver had logged avg of 29-30MPG and since I have learned the "tricks", I have improved the MPG, but still has not even touched 40avg MPG. Driving almost all highway, cruise control, very mild acceleration, watching the meters constantly, no A/C. On 550 miles, still hovers in the 30s. Does anyone know if mileage (70,000) affects MPG? In comparison with other "real world drivers", much less the marketed MPG, it's so low; it seems like something's wrong.

Per my Honda Dealer, MPG should improve with more mileage.
I suggest you take your car to a Honda Dealer and ask them to do a MPG Test.
If HCH is only getting 29 to 30 MPG, something is wrong! If you're getting 37 mpg, that is, on average, what I get with combined city/highway. We now have 7,600 miles on our 2009 HCH, and were told by the Honda Dealer the more we drive it, the MPG should improve. Sticker advertised MPG's on new vehicles are very inaccurate, and there are fine print disclaimers.
