Diesel Bombers - TheWrecker

Hey there everyone. I am just saying hi and introducing myself. My name is Brian Koecher. I live in Wasilla Alaska. I was a recent owner of a 2001 dodge 3500 5.9 turbo. I traded it in for a 2011 dodge 3500 6.7 turbo. The truck has 29k mile on it and I am averaging around 13mpg. I drive about 40 miles one way to work every day. My average speed is around 60mph. I was just looking for some inputs on how to get better milage with the 6.7 and not tear up my transmission. On my 2001 I had a edge attitude, efa air filter, and 4 inch exhaust. I was getting 18mpg in the winter and around 23mpg in the summer averaging around 60 to 65 mph. At around 105k I replaced the lift pump and transmission. I am looking for any input that would help me out. Thanks
