A little history

Pearl is now gone, owned by a friend. I'm waiting for Pearl S, a 2012 Seaglass pearl Technology package Prius.

I just entered my mileage logbook into a spreadsheet as I was curious about how we did. It was hard to scan through the tiny notebook.
In 71,000 km of operation our typical winter mileage was about 7 l/100 km or 34 MPG US, worst was 8.13 or 29 MPG US. Summer mileage was about 4.5 l/100 km or 52 MPG US, best was 3.74 or 63 MPG US, which doesn't seem to be an error as the tank before is normal and the tank after is also normal. Typical best summer was in the low 4s or 56ish MPG US, but the "typical" statement still stands.

Pearl wore Nokian WR tyres which were replaced last September with WR GII ones, and both were the stock size, running 40 PSI in front and 38 PSI rear.

I haven't yet figured out how to get the dates to graph properly so I'll leave that for a future day. My logbook records the odometer, date, distance traveled (which can also be derived by math), fuel used, and mileage in l/100 km. The spreadsheet does the math on its own, so I ignored the logbook entries for distance traveled on each tank and the mileage figures (the mileage calculator I used in the car is a cardboard slide rule from the Canadian Government, and isn't very accurate).

Anyway, some information you can use to compare your performance against. I never really tried to get "hypermile" type figures, I just drove conservatively. At the speed limit.

 

Lots of short trips, typically in winter. The best mileage was on a long trip in B.C. Does best at 70-80 km/hr which is typical for most cars. Just did the sum calc. on the spreadsheet. 169 fillups, average overall was 5.26 l/100 km. I usually fill up at 1/2 a tank.

Oh, and if you think the mileage was poor, compare to -real- data from "normal" cars. The smallest Suzuki I had as a rental once here got 8-10 l/100 km in winter. Not only was it a POS it was a guzzler! Don't be fooled by the silly ads. from other car companies trying to convince you a normal car can even come close to a Toyota hybrid! It aint gonna happen! Just like the mileage figures the Canadian Government allows. There is NO WAY a 2007 Prius can get 4.1 l/100 km consistently. Yup, I did it or better once or twice. On a good day, with a tailwind (or something). But the figures don't lie. The EPA figures are surprisingly close when the ambient temps. are reasonable.
Do keep in mind that a "nice winter day" here is -10C, and when it's not nice it's brutal. You're not going to get good mileage at those temps.
At least we don't have to suffer through +35 to 45C summers!

Oh, and I almost tear up when I see Pearl. I guess she was a great car for me. Hopefully Pearl S will erase those feelings and create new ones.
