Thats some nice numbers!!! Good job.
I am thoroughly impressed by those mpg's because we bought our 2006 Hybrid Highlander, 2wd V6, 4 months ago to replace our Suburban.
Our Highlander had about 111K on the odometer. I just looked at the "consumption" screen and it showed we have put 3760 miles on it and have gotten 22.8mpg. That pales in comparison to yours
But in our Highlander's defense....it is a basically a taxi. My wife is the main driver and her work commutes to her school are about 6 miles round trip, lots of taking kiddos to and from places in town also. Not awesome mpg's but we can live with it.
My questions to you are...
1 - Do you reset the "consumption" screen for each trip?
2 - Do you know if the system keeps track of overall lifetime mpg somewhere?
Thanks
