LMM Fuel Economy

That was doing 70 mph (cruise control), flat level driving with an occasional mountain range. I was enjoying ragging him about how much more comfortable my chevy was compared to his ford, until we figured his mpg. I kept quiet after that.

I haven't given up yet. I will be happy with 17/19 empty highway,and 11/12 towing. I am talking to a diesel shop for some less expensive ideas. I'm not going to spend thousands of dollars to get 2 mpg more. I also keep checking this board for any ideas.

I hear you... Chevy's definetly have better comfort features... My 2007 Suburban was getting 9-10 in the city and 14-15 on the highway empty/not towing. I'll be happy with 12 in the city and 17 on the highway empty. (20% better fuel mileage). I have nowhere to go but up! I'll get a better handle on what to expect for fuel economy in two months when I drive to tennessee and back.

You can rag on the new 6.4 Ford's, they get horrific mileage. A buddy of mine traded his 2006 Dodge for a new ford (both are dually's) and gets HALF (6 mpg!) of what the dodge got while towing his car to the races. He doesn't know if he can afford the new Ford because of fuel costs! This new DPF/regen requiement doesn't seem to be very MPG friendly.

I put on the Kennedy 4" turbo back pipe and saw an immediate change in mileage. I went from 15 around town to 16 and some weeks 17. I can get 19 steady on the highway running 70. If the wind is right, I have touched 20 but it is a rarity.

I too am looking to consistently get in the 20s with mine. It is a daily driver that I use to tow our camper about every other weekend.
