I'm going to be moving about 35 miles out of town and I'll need to commute to and from work, so I'd like to pick the brains of TDS members on some tips or upgrades I can make to help ease the cost to the ever rising fuel prices. Most of the trip will be interstate. So any tips on driving? I'd like to say that I'm a fairly conservative driver, I don't drive very aggressively. But I've found that on previous trips that if I drive around 70mph ( around 2000 rpm) my MPG are a litttle better? Any true to that or is it just a tail wind helping me out? Thanks in advance for all the advice. Jackson

Maybe get an economy flash on your pcm. Just a flassh should be pretty cheap. Make sure your tires are aired properly.

All the usual before you spend money on anything aftermarket - have the alignment checked, keep the tires aired up properly and check weekly, injectors cleaned or replaced depending on mileage, air filter, fuel filter, fresh lube in the diffs.....ETC. Good maintenance pays at the pump and vehicle longevity.
If you've got all that covered, try some of the aftermarket stuff. But that's money that's hard to recoup. As mentioned, feather the throttle at low speeds and keep it at 65 or 60 if you can stand it and you'll get some good numbers.
Use all synthetic fluids.
Keep it washed and waxed to reduce air resistance.
Keep the stock tires aired up as much as possible.
Don't have any lift.
Don't drive too fast.
Change the oil frequently, clean oil has less internal friction.
Get a bypass oil filter to keep the oil even cleaner.
Some people have reported a slight mpg increase with the 203* thermostat.
Change to thinner, harder, but not taller tires.
Don't use an aggressive tire tread, the smoother, the less rolling resistance.
Change the fuel filter and drain the water on schedule.
Check the air intake monitor, and change the air filter when necessary.
Check all of the tubes around the turbo for leaks.
Check the brakes to make sure that they are not dragging.
Don't carry any extra weight in the truck.
If you are really desperate, switch to biodiesel that you make yourself from used vegetable oil that you collect from restaurants, or modify the truck to run directly on used vegetable oil.
