Good, Bad, Average?

Forget the hand calculations. They aren't worth anything unless done over a very large number of tanks.

You mileage is fairly average. Not bad, not good, just normal.

Tom

 

Looks pretty good to me. Are all your trips longish (>10 miles)?

 

Actually I think your mileage is good. Most folks continue to drive this car like any other.... highway speed 70-75 mph plus fast starts from stop. Those folks are probably getting 40-45 mpg. One of the most extensive driving records I've seen is John's page John's Stuff - Toyota Prius and more. He has averaged 47 mpg over 114,000 miles.

There are folks here that do significantly better than your mileage. They had to work at it. With practice you will get better.

Best of Luck!

 

Definitely long trip territory :_> If you could stand to drive at 42 MPH your MPGs would be amazing.

 

There are really too many variables at work to be able to compare mpg from one car (driver/miles on car/type of commute/topography/temperature zone/tire pressure/altitude/ethanol concentration) to another. What YOU can do is try to improve your mpg over the same commute route you always take, and check your tire pressure frequently. Lots on this site regarding improving your mpg. Weekdays I average around 61mpg if temperatures are in the 70's, that drops a few on weekends due to shorter trips. I try to appear to be driving normally to other drivers, do a "modified pulse and glide" from 35 to 40 if traffic allows. Temps below 40 and above 90 will decrease your mpg significantly.

 

I would actually rate that as good.

 

I would say your mpg's is very good!

 

I drive in some fairly hilly terrain here & I think that is very good. If you have some stiff wind to go with it, anything over 50 is doing very well. I'm averaging 50+ over the last 3 tanks but we've been having some wind. When I hit the wind and/or hills it is tough to get much over lower 50's.

 

Hi Duc,

Average fuel econmy I think. Up here , and its been freezing or below for half this tank, so far, in the morning, I am at 63.3 mpg at 171 miles into the tank. In warm weather like you have there now I would be in the high 60's.

Your doing about what I was the first summer I owned my car. Your definately learning the Prius differences, and not just driving it like a standard car.

 

You can only drive into the wind or cross wind so many ways. A change of speed definitely changes things but still lowers the mileage. You can always change direction I suppose if inclined.

I've tried the hills with speed control, maintaining speed, speeding up & when going down & letting the speed sluff off. I even once at night & would never get over 60 mph & kept the mpg up & slowed to as low as 10mph on the steepest hills. Never did get over 55 mpg.

I can get into the 60s on a rare occasion, but the wind & hills always take care of that before the tank is empty. I am anxious to see how the summer mpg thing goes as I got my vehicle in late Dec.

 

DUC - you definitely got me beat! good job.
