2008 Mazda CX-9: Fuel Economy Update

October 20, 2008

I had the keys to the CX-9 for its last weekend in our LT fleet. So I took it to dinner, a walk on the beach and then we headed back to my place for a nightcap and a tearful farewell. And then I measured its lifetime fuel economy (I'm quite the romantic). Last month, I reported in the Big List of Fuel Economy that the CX-9's recorded lifetime fuel economy was 18.1 mpg. What I didn't mention then was that number was current as of February 2008. Seems we hadn't updated the fuel log in a good many months. When I plugged nearly 8 months of data into the spreadsheet today, I got a slightly different number.

With all the additional data, it was 18.2 mpg. (I did say it was a slight difference.) EPA estimates for the large crossover are 16 city/22 highway/18 combined, so we're pretty much on track.

Only once in all its time with us did anyone manage to squeeze more than 400 miles out of one tank: Dan Edmunds drove 444 miles (strrrrrrrrrrrretch!) on 19.331 gallons of gas and achieved 23 mpg. Karl Brauer pushed the limit of the 21.0 gallon tank with a fill-up of 20.683 gallons (squeak!) after 355 miles and returned fuel economy of 17.2 mpg.
