'best' is in the 55-60 range. With the big differences in temps the last couple weeks its hard to really be sure...but with this "warmer" weather (high of 5f here today!) I'm seeing around 18 at 55...

 

I played around a bit yesterday and noticed the following.

 

pinned at 55 on flat stretch, I get better mileage at M5 than at M6 or D... Going 55, it definitely drops into 6th when I go from M5 to M6 or D, so I'd assume that would get better mileage - not according to the DIC.

 

Also (and this needs more experimenting) I noticed that when it did manage to drop into V4, the mileage gets worse...but if I'm in M5 it drops in much less.

 

Over the last 100 miles, with the warmer weather/less remote starts, I've seen my around town MPG improve (on the DIC) from about 10 to just over 13...I'll take what I can get.

Low battery warning in small screen on dash. Did not want to start a thread but is any one seeing this (saw) this

I usually see my best between 55-65. This 25 average was yesterday
driving through Ohio with 65mpg speed limit I was driving between 55-75
depending on who I got behind. Probably averaged around 65 for this
particular average...4x4 Double cab 5.3

Those are pretty good mphs. The best I have had is 23.9 with a crew cab 4x4 Z71 doing an average of 76 mph for 100 miles with a slight tail wind. If it matters, I have an access cover on the bed of the truck.

I am just approaching 3k miles with a 5.3 DC 3.42 4x4, but it seems to do the best mileage when at 60-65mph, 22-24mpg. Maybe it is able to stay in V4 for longer periods of time verses running 55mph, just a thought.

I've noticed that temperature plays a big role in MPG's. We went through a -20F spurt and I would be lucky to get 14-15 MPG going 70MPH on flat road with no wind. Same road when 30F and no wind I'll get 18 MPG.

Running 65mph in V4, I get 23.7 mpg.

This is a perfect example of why to not baby your motor. Break that thing in and let it set them rings and get MPG like this all day long. Remember that the truck is learning your driving habits...drive it like you did your last vehicle. and drive it hard. Nice numbers bboyce536!

[MTB]

So, I've been babying this thing and getting suck for mileage. Yesterday I smoked the tires leaving a green light. My 2007 would never do that. Ever since doing so my mileage average is bumping up... Starting to believe there is Merit in Breaking it in... Just hope I don't get a ticket doing so...

Best MPG is 19.5 But I do not know when or what speed.

Average is now 17.0

 

 

The numbers are nice but it's hard to compare with others unless you know what you are comparing to.
