I did a trip to the States a couple weeks ago. I set the cruise at 75mph. I averaged 6.9L/100km for most of the trip but I did hit 85mph 4 times passing. Overall I averaged 7.2L/100km both ways and there was a slight head and side wind. So, overall I was impressed with the milage this 5000lb truck returned. It gets 18mpg more than my 4cyl gas Colorado at the same speed!
