Over the years I learned that driving fast will use more fuel. If you want to save money slow down. I think back in the Early 70s it was 55 mpg across the USA for a reason to save fuel. I find the best fuel Eco when the tac is under 2000 rpm. My auto 3.73 overdrive kicks in and I stay at 105kmh I'm below the 2000rpm range. Now on the other hand I would like lower gears for off road, but I like traveling also. So here I am, Decisions, Decisions
