I live in Kansas City and got my HAH in late May. I've made numerous long trips. During the warm weather, I would average about 36 mpg driving to Davenport, IA at over 70 mph. However, when I made the same trip in 14-degree weather at the beginning of December, the mileage was down around 29-30 mpg. Since the weather has warmed up during the last week, the mileage has again improved. I can only speculate that the density of the cold air affects the gas mileage, but I would never have guessed the effect would be that large. Perhaps there is an engineer or other science-brained person following the thread who can tell us if the air density of the cold air can acutally make that much difference.
 
Don't forget that gasoline formulas change with the seasons, and winter formulas generally achieve less mileage. This is true in my Accord EX 4-cyl. When I got the car in October, I was getting 30mpg regularly. Now I am down to an average of 26.6mpg (according to my log). It makes a difference depending on where you live, i.e. the Northeast uses a different fuel formula than does the Southeast. Hope y'all have a happy holiday!

I tend to agree with the graduate. I live in New Jersey and they used to use an additive during the winter (I believe it was an oxygenating additive) MTBE? That reduced mpg by 5-10% but I am not sure it is still added.
 
Also my local station has recently posted a sticker on the pumps that the fuel may be up to 10% renewable energy which, I suspect, means alcohol based. Alcohol has about quite a bit less BTU content than gasoline so that would also reduce MPGs. Check with the local gas station about any of this.
 
When the use of renewable fuel sources becomes prevelant, then all vehicles will get less mpg's but I feel a tradeoff that will make us give less $$ to OPEC is worth it.

I agree that less than 30 mpg is a disappointment. However, I realized when I purchased the Accord (rather than a Prius) that I was buying Honda's version of a hybrid: basically a gas-powered car that uses hybrid technology around the edges. Let's face it, the biggest gas-saving factor this car has going for it is the use of the 3-cylinder ECO mode, which is not new technology is not even hybrid. But I did want to buy a hybrid--I wanted to support the hybrid market and support the technology, and I didn't want a Prius or an SUV. Toyota's hybrid technology seems to be more gas-efficient. I eagerly await the introduction of the hybrid Camry and I hope there will be some hybrid Lexus CAR models as well. If those had been available, I doubt I would be driving an Accord.
 
In the meantime, I bought the Accord...kind of a sorry excuse for a hybrid, but a car with very nice styling and handling, generally suitable room in the back seat, and 10%-15% better gas mileage than an all-gas Accord. Yes, the additional vehicle cost was a rather large premium to pay for 10%-15% better gas mileage, but I look at that as what I'm willing to do for the environment and less use of oil. (I also realize that most people look at it more closely as a dollars and cents issue than I do.)
 
And now that it's 2006, don't forget to include the hybrid tax deduction on your income tax form.

Hello all. I live in west texas, the weather in the winter here has been consistently around 70 degrees and my HAH has been getting around 41 on the highway and 32 in town. I hope this sheds some light on I am in sales and drive my vehicle around 350 miles per week. I can't believe my gas savings and its excellent on roadtrips. My last trip i was averaging at a speed of 90mph around 32 mpg. hey, at that speed, why complain about 32mpg?

Samething happened to my HAH. I've been driving the new HAH car only a few days. Mostly local driving around DC, I got 19.8 mpg from the dashboard. I need help too.

I see all of the postings where people are getting 37-40 mpg and no matter what I do I can't get above 31. Florida is FLAT, and I am an easy driver - slow starts, ECO light on most of the time. My highway driving to work is only about 20 miles each way and about 5 miles regular roads, not much traffic, only 1 or 2 lights. I now have just over 1,000 miles on my new HAH. Do you think it will get better?
thanks!

 
Don't forget that longer trips yield better overall mileage! Have you gone over 100 miles at a time in it yet? If you do, you will likely see a marked improvement, because the engine isn't spending fuel cranking the car or warming itself up to normal operating temperature. I'm no expert, but I know this will have SOME effect, however small.

Technically agreed with thegrad.

I see also that, with the advent of cold weather here in NJ, the MPG has dropped on my HAH.
 
Aside from a recently started use of 10% ethanol(at about 1/2 the BTUs per gallon than petro) in pump fuel and the likely use of MTBE oxygenation additive (another energy killer) I still am not satisfied that the appreciable reduction in MPGs I see is entirely due to those.
 
Of course the most significant culprit is likely the cold weather.
 
Therefore I researched my local Honda parts department and there is a block heater available for around 80 clams plus 120 for installation.
I anticipate this would make a significant improvement in fuel economy by allowing the oils etc to be more fluid at startup and also allow the temperature enabled "Eco" mode to kick in sooner.
 
Does any one here have firsthand experience with this option?
