satisfied? Tripsss? Not trip?

I drive 800 miles a week, mpg is high on my list. I have done everything I could to try to keep them up as much as possible but these trucks are not capable. I can keep 20 mpg for a few hundred but as soon as the dpf kicks in it’s doneskie. Now I haven’t got the 10 speed yet and some people live in better spots for mpg, for example flat land. Another big one is the humidity. The dryer the air the less regens and that equals mpg gains. I feel pretty good getting 16 plus mpg’s. That’s up from an average of 13.5. I slowed down, idle less, and turn traction control off. Traction control was eating up my back brakes too, I assume because I floor it from takeoff and it didn’t like the back wheels breaking traction. But satisfied? That’s a weird question. I’m not involved with any of you on a personal level so satisfaction isn’t had. But my attention can be sparked here. Someone post 20 mpg’s over 5000 miles I’ll be trying to learn how to duplicate it.

op, don’t take the internet so personal, it’s the internet. A digital chalkboard. People that seem like jerks would probably be charming in person. Even the dude posting above me and George c would probably get along in person. That’s just how life works. My steering column gets very dusty too, quickly.

 

Lesson #1 in getting higher MPG with these trucks: Don't do that right there.

 

“I feel pretty good getting 16 plus mpg’s. That’s up from an average of 13.5. I slowed down……”

 

Just pointing out that not flooring it will get you closer to that 20 MPG. Looking forward to getting my new truck and seeing what I get with the 6.7. Currently averaging 14 around town with my 6.2, 8.5 with towing our 30' TT.

 

I love gambling, but even that’s not something I would bet on.

 

So what your saying is there IS a chance?

 

My trucks get such a big difference in mpg depending on what I'm doing. For the first 6 months, I got in the truck drove 2 miles and got on the freeway, drove 4 exits over and got off freeway and a couple lights to the job site. a little chasing during the day and return home at the end, I get 14 mpg. Now I've started working on a project 20 miles away. get on freeway go 20 miles and couple stop lights to job. and I'm seeing 20 mpg. Hook up the horse trailer and it's 11 maybe 12 mpg. If you look at the 20,000 mile avg for my truck. It's around 14 mpg. I tow too often and too many short trips. But I know if I get in the truck and drive empty on a 300 mile trip, I'll average 20+

Then factor in Winter vs Summer fuel. Everything you buy in our part of the country gets winter fuel begining in October. So I automatically loose 1-2 mpg

 

For me winter air increases distance between regens greatly but warm up idle times increase significantly. Kinda fighting each other. Both have great effects on mpg. Never associated winter fuel with anti gelling additives as an issue.

 

Winter blend fuel has less BTU's available, so it takes more to do the same job.

 

but winter air has more o2 for better burn, less soot and increase distance between regen. Should trump decreases efficiency of a little anti gel.

 

Well the way I took your statement was that his claim was no big deal because it wasn't on a large enough scale. So I used your 5000 mile figure and divided it by 237 miles. Which would equate to 21 short trips. No real difference. In fact if a person is consistently filling from the same station and pump like I do (I'm an odd duck), they'd probably see numbers that are even more accurate than a 5000 mile jaunt across the nation.

I hand calculate every time. The lie-o-meters in my vehicles are sometimes close, but frequently they are high or low 1 mpg. I never trust the things, but they can be close enough that I'm not going to browbeat someone for relying on them. Not saying you browbeat O.P., but I see he got flustered and took his ball and left. I just wanted to chime in and make a point.

My pickup can absolutely do 20mpg in 5000 miles. To hedge my bet I'd put the stock air dam back on and go back to the 275/65r20's from my 37's, I'd also try to keep it at 65 mph. I've done multiple 700+ mile trips on 37's and seen 19.xx mpg. All stock 21+ was pretty easy even at 75 mph. Some rigs can't do it, but some can. Plenty of mountain passes up here in the PNW as well.

 

so your the one that got the magical truck. I’m jealous!

 

Higher O2 content in the air, just means the ecm injects even more fuel trying to hit its target fuel/air ratio, so lower fuel economy.

Going to test out whether having a tonneau cover on helps out any on a trip this weekend.
Also, weather report says I'll probably have some tailwind help too.

Looking to top 20 MPG by a bit, last couple of tanks I checked were 19.9, calculated, MPG.

 

As an aside it gets terrible mileage in town. Never seen better than 12 IIRC.
