I must confess... the page I keep up on the driver's info screen shows the average mpg. On my 5.7L, I average 19.1 mpg which is a majority of city driving, somewhat aggressive. With mainly highway driving, I've between 24-25.5 mpg, again depending on driving style. BTW, the 19.1 mpg is 8.1 km/L for you metric guys.
Thanks for the conversion Jerry... I have never looked for the MPG on my display, I’ll have to look for that in the spring.
