My uncle drove his big Lexus (I can never remember the Lexus names - their top of the line lux-mobile) claiming 31 mpg (he doesn't have the hybrid) - I'm very sceptical that a 4000+ rwd vehicle got that kind of milage - he relied on the trip computer for the milage.
I always calculated my mileage since I was 16. I have found the Rainier display to be within a tenth or two of actual mileage, and the Malibu display is actually about 2 mpg lower than actual. Which, of course, is good to me! When we had our '06 Town and Country, the display was about 1.5 mpg higher than actual.
