I've had the truck for almost 2 years now. Routinely see 16.2 on the overhead computer. I no longer hand calculate as it is usually right around what the computer says or a half mpg below.

I quickly dropped the experiment of driving with OD off and then switching to on depending on the driving conditions. No real difference and a hassle to constantly switch.

If I really baby it and keep it under 65 mph, I can average 18-18.2 at best. It seems that if I'm on the highway, the best thing to do is keep it right around 60 mph.
