My Prius reached the age of 4 last week. I have plenty of data on my web page, but here are some of the highlights. Total Miles Driven = 47,277 (11,852 miles/yr) Average Mileage = 53.9 mpg Average Miles per Tank = 514 Average Gallons per Fillup = 9.54 Times Stopped for Gas = 92 $ Saved in Gas vs 25.0 mpg car = $2,512 Total maintenance cost = $552.81 Best Tank MPG = 60.8 Here's the mileage data. Note the drop off last spring - I got new tires (replaced with Integrity OEM) at the same time the 10% ethanol got added to the gas. Double whammy!
It looks like it doesn't get very cold where you are. Here near Toronto Canada our temperatures range from +33 to -33 - that's Celsius of course. Which ever way you measure it, it's a big range. Throw in a couple feet of snow every week or so and the mileage goes for a major dump. Thank goodness I can walk to work. Buck
Well Paul, I guess that means it's just about Priapus' birthday. He'll be four years old on Aug 24th. You always have some great data and charts. Thanks for sharing. My favorite is this one showing the correlation between temperature and mileage:
