With the continuous increase of gas/diesel prices, how can you conserve diesel of you are driving a SUV besides not driving one? I'm a new driver by the way. Thanks in advance.

There's people out there that will insist that you have to SPEND money to SAVE money for example by buying a programmer, a new intake, and a spiffy exhaust system. That may all indeed work, but won't pay off for a certain amount of time.
The best way to conserve diesel is to keep on top of your maintenance as the owners manual specifies, NOT lift your vehicle, and drive the speed limit. Even better, if you can, ride with the big rigs and keep it to 55 MPH.

Speed kills economy. The aerodynamics on this truck are non-existent. The faster you go the fuel consumption goes up. (Keep the tailgate up, and consider a cap or cover.)
DON'T IDLE ANY LONGER THAN YOU HAVE TO. Seems silly to have to say it, but sitting still you're wasting fuel. If you're in traffic & its stopped for over 3 mins, shut it off. Also, extended idling w/out a load is harmful to the engine. If you MUST idel for extended periods, raise the idle to over 1k rpms. This uses more fuel, but is better for the engine.
Also keep your tires properly inflated. Under inflated tires can hurt milage more than you would think. And as others have said keep off the gas pedal, on these powerstrokes not letting the boost go past 20 psi seems to be the sweet spot.

I'm curious about the idle speed thing you said. This is my first diesel, so I don't yet know all the ins and outs of diesel engines, but I thought ( I guess since you always see the big trucks idling while they aren't occupied ) letting a diesel idle wasn't hard on it. I don't let mine sit and idle , cause it's too expensive, but I didn't know it was harmful to the engine. Can you explain?

In cooler climates, letting a diesel idle for an extended period can cause cylinder temps to drop below operational levels. When that happens, unburnt fuel can get past the rings and into the oil.

BTW, people, the proper tire pressure can be found on a sticker on your door jamb. And the values listed there are for COLD **STOCK** tires. If you just got back from a drive that was more than one mile, give it a rest and come back a couple hours later.
