I am a new member and I was looking at all the high MPG's people are getting. I am wondering why I may be getting such low numbers (37-39 MPG). I do mostly city driving which I know will affect it, but I have never seen above 42 even on trips. I do my best to take off slow and use moderate pedal control. I have owned my 06 HCH for about 6 months. I got it with 26,000 miles and it now has 42,000 miles on it. If anyone has an idea how to improve my MPG's, please let me know.

Thanks,
Dan

Hi,

I think some of the HCH owners once posted something about the 'defrost' being on by default when the car is started. Just something to check.

We just took possession of a new HCH II and working on our first 150 miles. In five days our average is 37 mpg with a combo of city and Hwy. There's usually 2-4 occupants.

Today we were stuck on the freeway behind a truck accident moving at 5-8 miles per hour and the gas motor was running (unlike the Prius from my understanding). We watched the mpg drop 1 mpg during that 1 mile 20 minute trip.

With the new MPG numbers (40 city and 45 hwy) on the 08 sticker, getting high 30s in our primarily city driving scenario seems appropriate. Hoping for higher as the car breaks in.

You just have a heavy foot compared too most? You must have a feather foot in order to get numbers over 50mpg. If you are in a hurry it is impossible to achive high numbers.

Try the HCH-specific area for more responses, and try the search feature. There is a wealth of info on this very subject.

Quickly, I can say check your tire pressure, increase it a bit over what the door jam says, slow down, try to use your brakes less (look ahead in traffic), check your air filter, accelerate slowly...

Are just a few quick ideas. Do a bit of research and read "Tarabell's article".

You can do it!

Along those lines, make sure that your air conditioner is displayed "AC-off", as it could be on (even in cold weather) in all other settings.

Honestly, my mileage has been pretty crappy too since the weather got cold. I'm lucky hit 50mpg on in the cold mornings and the high 60mpg commutes home are now a distant memory. It's enough to make me consider an engine block heater...

Commuter car, grocery getter, and summer road tripper--average 10k miles per year.


Winter road trips and ski trips, bad weather commuter and my wife's "daily" driver--expected average 4k miles per year.

In addition to what everyone else wrote, I would try different gas. Some stations use 10% ethanol in their gas. The alcohol will make you FE suffer. Definitely read Tarabell's article and practice your driving.

GOOD LUCK!

Thank you everyone for your advice. I will be trying these things and I will get back to you all soon.
Thanks,
Dan

Be patient and alert to what you read here and what you experience in your car.

I've been working on it for four years now and am still learning.

Need fewer troops to support.
Drive a hybrid.
Best tank 71.65 MPG.

Before this car I spent two years learning hypermiling on my 2004 HCH1.

My own 2 cents:

From personal experience, however tempting avoid the urge to add more gas going uphill. Slowing down on the rise isn't a bad thing.
