LML Fuel Economy

[FYRWOOD GUY]

my truck just went to 14 mpg and its still got the break in oil in it.
it's on it's 4th tank of fuel.3rd fuel filter. 2545 miles.63.5 gal fuel tank(s)



i'd like to know what other 2011 3500HD people are getting for MPG with their rigs

I'm in the market and would like to see some real world reports on mileage. All I have found so far is predictions and outlandish claims. Maybe there's not that many owners of 2011s here yet to report?

In my experience, no way is the LML more fuel efficient than the LBZ; towing that is. Just got back from 1500 mile trip in which the conditions were as good as I've ever experienced and the LML was a tad less than 10mpg. Just a guess but I'd suspect the LBZ would have been about 12 on that haul. Non towing the LML may be 1mpg better city and about the same on the highway.

Well I don't know what others are getting but I know what our lml is getting and what our lbz got mpg wise and we tow very heavy. And it isn't an out landish claim. I have no reason to lie. And even if this truck got less mpg than our lbz did I would still be happy. Just due to the brakes and so forth on this new truck. I haven't changed my fuel filter yet if someone has changed their fuel filter 3 times in 4 tanks of fuel ? you think maybe fuel is their issue and not the truck ???. I only have 7,000 miles on it so far and love it.

11,000 miles, new fuel filter and oil, last towing trip of the season, unfavorable wind, 8.1 mpg. LBZ conservatively would have been 1 mpg better, that route run enough times to know. LML unloaded, adverse city, 12.5, LBZ would be 11.5. LML pulls hotter, but a tad stronger. Overall LML a much better truck in so many respects.

I have noticed big differences in mpg on my last 3 d/maxes when going from summer to winter blend fuel. The winter fuel seems to drop it a couple of mpg on average. But then maybe some of that is due to warming up and idleing in cold weather. And now with remote start that add's more idle time. Spoiled "haft" to go out to a warmed up truck now. LOL
How did we survive before all of that?

Changing fuel filters 3 times in 4 fillups. Why? You are probably loosing fuel each time you remove a full filter some probably runs out before you can get the new one on. Let it run a few thousand miles, oh and by the way , my fuel mileage continued to increase for about 60,000 miles incrementally just a little every few thousand miles, it took that long for the engine to feel like it was finally broken in. Once you've got the engine and drive train broken in where it runs more free, you should see your mileage increase. I've followed WildBills posts for years and you may just as well believe what he tells you because no one has a good enough memory to lie about something, they will always get caught. I've never heard him say anything that contridicted what he previously said in other posts. I have a good friend with a 2011 and he says he's only getting about 14 mpg. One day I looked at his new truck. It's got a giant steel flatbed with double heavy headache rack, there are two tool boxes loaded, an auxillary fuel tank that he had special made that holds 150 gallons of diesel, he's got chain saws, shovels, tools of all kinds strapped to it. The back seat is folded down and so help me there is not room to put a lunch pail in the back seat, it's stacked to the headliner with stuff he uses in his fence building business everyday, so he never unloads anything. He's usually towing a 16' lowboy trailer with a bobcat on it with fence posts pile up 4 feet deep and he wonders why he can only get 14 mpg. I asked him what his previous F**d truck got and he said you don't want to know and besides it cracked two sets of heads on that 6.0. I assured him the only reason he will have to get rid of the Chevy is because he wants a new truck. It's not gonna break and it's not gonna wear out, unfortunately he will never know what mileage it gets empty, because it never gonna be empty while he owns it.

bought new 15' 2500HD last August; now have 23000m, about 85% towing a 3 ton TT cross country. So far avg. mpg towing is about 12. Ranges from 10 to 17 depending on wind. Crossing the mtns. is not an issue; acutally get mileage above 13. It's the wind on the plains that knocks back the avg. The 30' trailer is 11' tall, and it's like towing vertical sheets of plywood down the road.
Am picking up a new fiver (5 ton) next month in WA. will keep posted what new mileage is. Trailer is taller, but has "aerodynamic" cap in front, whereas now I have a wall of fiberglass on my TT.
Diesel is awesome, as they say "you'll never go back"
