My best in town mileage is 30.
In warmer weather, I was doing closer to 40.
A lot of the gas we use here is 10% ethanol which drops mpg, too.
I'd like to know if anyone in the midwest with my winter weather conditions and fuel blend is doing 40 or more.
If they are, I'm doing something wrong.
Thanks.

i can see an ICE engine losing maybe up to 20%, but not 40%, like the example provided. i'll just say i have never experinced such a drop in mileage in any vehicle i have owned.

I did try using high-octane fuel twice. Once was in summer, and the second time in the fall.
 
The results were similar : a 4% improvement in fuel economy, but a higher cost per mile. So I will stick to standard fuel.
 
The explanation for the higher mileage with high octane is a known scientific fact : Higher octane allows more spark timing advance (automatically performed by the ECU), wich improves energy efficiency.

On my routein trip of 120 miles that I normally get 40.5; today at 22 degrees I got 37.5. Coming back I typically can get 39 and I got 37.7. It was 55 degrees on my return trip.
 
Update: Took the trip again for Christmas. Different variables. It was 45 degrees, 750 pounds of passenger and a full trunk. Going down I drove 80 to 85 (it has been some time since I've done this. I averaged 32.5 mpg (this is the trip portion I can average 40.5 mpg in warm weather, driving under 70). Conimg back, about the same same variables as going down except I drove 75 on cruise and I got 35 mpg. The difference in 75 and 85 mph is very significant.

The difference between 75 and 55 is also very significant, and those of us who are concerned with saving fuel, along with getting better gas mileage, don't need to be driving 85 mph. Doesn't make sense to me to be concerned about getting better mileage or concerned about fuel supply and demand (thus prices), and then drive at 85.

I think you might be surprised. I certainly was. With the new fuel consumption graphs in the hybrids it's very very easy to measure specific situations for even limiited durations. Having driven normal ICE's all my life all I had to go by was a tank average at each fillup.
 
Most times the tank average would be 32-34 mpg but sometimes it would be 27 mpg. There was no way to identify why one tank might be lower than another. now with the Fuel Consumption graphs this can be measured and quantified even for limited durations.
 
This Fuel Consumption graphing would be very very useful in every vehicle. It would show clearly the effects of different conditions and different ways of driving.
 
You may be right about ICE's being affected somewhat less by these conditions. But any estimate is an SOTP one.

Lessachs:
 
Did you mean to say,
 
"my best in town mileage is 30 MPG" ?????
 
In a 2007 TCH, you are only getting 30 MPG in city driving? On dry roads? At speeds of 25-45 MPH?
 
That cannot be true, or something must be wrong with your car or the air in your tires must be about 20 PSI.
 
My 61-yr-old mother was here last month (who had never before driven a hybrid and is not a slowpoke per se) and she drove my TCH in Phoenix city driving and her lowest for 140 miles of driving was 35.3 MPG. I had to wonder how she got that bad of mileage, because I would have to drive like a maniac to get below 35 MPG.
 
If you are getting 30 MPG in the above conditions (dry road, speeds of 25-45 MPH, and tire are at least 32 PSI) then one of two things are happening:
 
1. You are driving the car too fast and too hard.
2. There is something wrong with your car.
 
There is no other explanation. Getting only 30 MPG in a normally-performing TCH is almost impossible.
 
PS I thought of another possibility. If you are in REALLY COLD weather, and all your "in town" trips are 5 miles or less, you could probably do as low as 30 MPG because the car is never getting heated up enough to use the HSD system properly.

Not everyone on this board would agree with you. I have an overall average of 39.2mpg, so I'm doing my part. I typically drive under the limit. However on this trip I wanted to make some time. Gettin 32 mpg is still doing my part as my last car, Infiniti FX45 would have gotten about 15 mpg driving at that speed.
 
Then again, and I've said it in previous posts, I'm not an environmentalist, although I don't mind that my car is better for the environment than most, I simply wanted to save money and at the FE I'm getting and the tax credits I've gotten, I've more than exceeded my expectations.
 
While I do most of the time, I don't plan to drive under the speed limit all the time to obtain maximum FE numbers.

I live in the Chicago area and I've about 5000 miles on the TCH since August. My 'warn' weather average is about 35 and my 'cold' weather average is about 32. The gas mileage is terrible when the trips are short, I suppose the ICE has no chance to warm up.
 
I get better mileage than my wife. I made a 50 mile trip on 12/24 when the outside temperater was between 40 and 50, and I average over 40 with about 75% highway.
 
I'm happy with the gas mileage and I can understand the gas mileage may fluctuate due to driving condition.
 
I don't think your car is doing anything wrong.

I must point out to larsb that the sort of city you drive in makes a big difference.
 
I remember driving around Phoenix and I wondered about how relaxed a drive it was. Synchronized traffic lights, miles between them, no starting, stopping nor racing for the next green.
 
In Montreal, I regularly drive 15 miles to a downtown customer's. On some days, I get 38+ mpg, while on other days I only get 25 mpg on the same course (all numbers are US mpg). All this because of stop signs and traffic lights.
 
Since I've had my TCH, I even changed some of my routes to save up to 40% in fuel. My tire pressure is 36-38 psi.
