Poor gas mileage

[JF19Longhorn]

On flat ground @ 70mph I'm lucky to see 16-18mpg on the instant readout. The MDS never kicks in above 45'ishmph unless I'm going downhill or slowing down and have a strong tailwind.

 

[Scram1500]

My MDS will kick on in 3rd gear around 25 mph and if I'm careful I can have it stay on through all the gears up to about 6-7th gear 50ish mph. The terrible sound and vibrations that are generated aren't worth the fuel savings. Whenever I forget to disable MDS my truck will quickly remind me

Yeah I'm about the same as you with MPG's. Flat roads cruising 65 is about 23-26mpgs. at 70 it's about 21-24mpg if it's flat. I'm about to level the front of mine 2 inches so I'll see if that decreases this great mileage I've been getting. I didn't want to but I was tired of looking at the raked look. I had the rear lowered, but I didn't like how it drove and when I towed anything it was horrible, so I decided to level the front a little.

Curious to see how this affects your mpgs

I'll let you know sir. It's funny, I've noticed that we are usually on the same threads doing our homework before we do any mods HAHA.

 

[theblet]

Haha yea. I prob won’t be doing much modding until warranty expires. So you can go first

I feel you, I always buy extended warranties then mod it . Good thing it won't void engine and transmission or electrical so it's all good. I'll just do the level and some bigger tires.

Just got my 2021 Built to serve, 3.21, 4x4, fully loaded, 2.5 inch ready level/lift with 295/60R20 Nitto trail grapplers. Drove the truck home, all highway and averaged about 13.5. So far in the city, I am at 12 MPG. I suspect the big tires are the culprit. Not complaining at all, if i wanted good MPGs, I would have stuck with my Malibu. Anybody else have mud tires and is experiencing similar MPGs as me?

 

[theblet]

The tires will definitely hurt mpg. Especially if they are load range E, as they will weight a lot more.

Probably should of went with a A/T tire but damn the M/Ts look good, thanks for the reply

Yes sir. They do!

Yeah those tires probably weigh in at 70 pounds a piece but they do look good. As long as it puts a smile on your face you are good right? Haha

Just letting you know, I just finished the 2" motofab lift on my truck. Here comes the real test of this drops my MPG's or not haha. I don't think it looks bad at all with the stock tires so I'm going to use them until I've worn them out.

 

[theblet]

Nice! Got any before and after pics?

 

[Whoa_Ram]

I’ll take some after pictures here in a bit. Just went for a drive. I should have some old before pics I can post.

I did that same leveling kit a month ago and haven't really noticed much change, still in the mid 18s for mixed driving. At interstate speeds of 70+ I think the economy may be dropping a bit with the level....but I only drive on the interstate about 3 times a year. On relatively flat highways of 60-65mph the truck is usually about 21-22mpg in 8th gear.

I'm also sticking with the stock Wildpeaks until they wear out, they aren't my favorite tires, but they aren't bad either. Haven't had them in the snow yet though....

I’ll have to see how it treats me on the highway. I have a feeling it’s going to drop a bit for sure.

More than you're prepared to see for sure!

I think if I get an aggressive tire it might drop. As of right now I’m not doing horrible. I’ve put about 100 miles since the leveling kit. It’s tough getting anything above this which before it was a bit easier but the wind resistance has increased slightly.

I am actually happy with my gas mileage. This is average driving for 2 weeks, town and highway mixed.
