At the peak!

[fbhjr]

My car has reached its peak mileage for the year, 51.65 miles per gallon.
(21.96km/liter, 63.03 miles per imperial gallon, 4.55 liter per 100km)


It is a hybrid car (PriusC) and very sensitive to the temperature of the
air around it. It does much better in the summer, and worse in the winter.


If you chart it against air temperature at time of gas purchase you can see
it more clearly:


Last year I got much better mileage than this year. I’m thinking that was
the weather as it was a cooler than normal summer.
We’ll see how the winter goes.
Snow really kills it.
The heater, light, wipers all add to the reduction in the cold. But,
pushing snow out of the way is by far the worst.

Hopefully it won’t be a bad winter.
We’ll see.

I have to say your record keeping is amazing--is there some way that the car itself records this? I know that screen that gives you the data, but keeping a record and charting it! However, based just on memory, that's the kind of variation I get, though my warm climate probably moves the whole graph a little higher.

You can reset the trip counter every tank of gas and it would do that.
I use my cellphone and take photos of the odometer and then the gas pump when I pump. Then, add everything to an excel sheet later...
