Am I missing something??

I was looking at the Achievement Records in the database, and ran across xcel's 1,345 miles on a tank of gas in an Insight at 95.3 mpg. If my math is correct (1,345 / 95.3), that's 14.11 gallons of gas. I happen to have an Insight brochure right here beside me...it says the tank is 10.6 gallons.

Now, I've put more gas in my Civic Hybrid than it says it can hold (13.2 gallons, and I put in 13.4), but never 3.5 gallons!

Are these numbers correct??
