I have read and talked to few guys that the early 6.0 litre engines respond well to chips, better mpg and some will help reduce the constant downshifting issues that the 6.0 has. I don't think you want to go to 3.73 gears. The 6.0 just doesn't make much torque down low just lots of hp up top.

When you replace your tires there are ones with a much lower rolling resistance and they may not have as aggressive a tread but they will help maximize mpg if kept at the correct pressure.
To minimize what I spend on gas and diesel I use www.gasbuddy.com to find the cheapest prices both locally and when planning a trip. I save $0.20 to $0.50 cents per gallon by finding the cheapest places to fill up the tank.

Might I make a suggestion.
Down here my 93 Chevy 7.4 runs on gas and LPG(propane). The gas sells for $1.46 per liter ($5.52/gal) and the LPG sells for $0.65/liter. When on LPG it runs about 25% cheaper in $/mile. It is computorised and altitude sensative to give optimum performance. I do approx. 800 to 400 m/week now, as the dually is used for servicing on rural properties. The system paid for itself in the first two years as I was doing over 1200 m/week. I lost about 250 lbs payload due to the tanks. If you have a good dyno mechanic around you, ask him to spare you half an hour to talk thru it. The spare tyre sits in the back during the week with my tools, and I am making a front mount for carrying it when the TC is on.
See how you go, it might work as well for you, as it has for me.
