Opinions on my MPG?

So from reading posts on here, I have determined that I get way worse fuel mileage than the average poster on here. I keep reading where people get 20 mpg, 23 mpg, and even 25 mpg. Leaves me scratching my head and wondering why I only get 16 mpg. I will walk you through me, my driving habits, my truck, etc. Would be interested in opinions on whether my mpg is consistent with my setup and conditions.

Truck:
2016 2500 CCSB Laramie 4x4
118k miles
Leveled
285/65/20 Falken Wildpeak AT on stock Laramie wheels
HPP SOTF Tunes using EZ-LYNK
Fully Deleted with 4" turbo back exhaust with resonator

Me:
44 years old
Drive the speed limit or within 5 over
Drive about 3500 miles per month normally 50/50 city/hwy

I started using Fuelly. So far I have done 18 fuel ups. My average MPG for those 18 fuel ups is 16.3. My best was 18.2 driving from Minneapolis to KC last month (all highway, just cruising at 75 mph). On my normal daily driving (50/50) I get 15.8-16.

I change my oil, oil filter, and fuel filters at regular intervals and use OEM filters.

I was really expecting to get better mileage than I am. I have picked up almost 2 mpg since I deleted. I hand calculated before I started using fuelly. Am I missing something here? How can I be getting some much less MPG than others with a similar setup? I appreciate any input y'all can provide.

In light of the fact you drive 50/50, city/hwy, your numbers sound perfectly normal to me.

I drive a '16 3500 SRW Cummins. 17-18 mpg at 75-80 mph. Takin' it real easy around town, 14-15 mpg. Doggin' it around town, 11-13 mpg. I can hyper-mile at 65 mph and get 22 mpg. 12-13 mpg hauling a 3.5k in-bed, hard-side camper. 10-11 mpg towing a 10k TT or 12k 5th wheel at 65 mph. All hand calculated. EVIC typically reads around 7-8% optimistic (i.e., 16.0 mph EVIC, hand calculated 14.9 mpg). Gotten the same mileage since the truck was new. 43k on it right now. Completely stock. Did replace the original 275/70/18 OEM tires with 295/70/18's at approx. 40k. Didn't notice any change in mileage.

The guys that get 20, 23 and 25 mpg are about 90% full of ____ and 10% grandpas/hypermiling.
Remember, most all men lie about 3 things. The size of the fish they caught, the size of their ____ and their truck's gas mileage!

I guess the lesson here is to not believe everything I read on the internet. When it all comes down to it, I am still getting way better mileage than my old Ford gasser that got about 11.5 mpg. And right now, I am getting diesel for .20/ga less than the price of gasoline. So that disparity is even greater.

4WD doesn't do as well as 2WD, which is where my high fuel economy comes from, plus my driving style and favorable winds.

This is the best I've ever achieved...

Have you recalibrated your speedo to match the larger tires? That’s going to throw your number off a little.

Some people are a little optimistic when bragging about their milage. For mixed city highway what your getting seems about right considering your turning almost a 35” tire. Have you calculated a strictly highway trip on a full tank?

Don’t expect huge milage gains from a delete like the previous generations, I only picked up about 1.5mpg.

According to fuelly my last trips average milage was 20.6, that was all highway turning 35x12.5’s. My evic was showing 23 mpg if I remember right. Empty around town I’m probably getting 14-15.

What you get is normal and what 99% of the people out there get. Just go look on fuelly at all the other trucks and you will see. There seems to be some "unicorn" trucks on here (or victims of common core math) that get in the 20's+ on average but that is not the norm.

Youíre pretty close to my numbers. My 14 is bone stock, not leveled but on 285ís. My truck was incredible on fuel for the first 40k miles, but I had a never ending check engine light. Finally square up with Ram to get the new SCR and whatever update and lost an honest hand calculated 3 mpg.
My leveled second gen averages about what youíre saying and itís probably 1,000lbs lighter. Look into low rolling resistance tires if youíre really concerned, or dismiss the B.S. for what it is.... Iíve been driving cummins powered pickups since about 2002 ish. I hypermiled my 99 qclb to 26 mpg once at 55 mph, and the 02 qclb 4x4 got 25.2 mpg from Salt Lake City to Flagstaff once, at 62mph on 35ís.

Ltngdrvr, please, not again! This is the second time in short order that you have posted mileage numbers that are more than three times higher than my good ones.

If my 3500 ever saw this I'd have to build a cry closet for it.

Maybe if we start telling people that the brain is an app, they will start using it?

50/50 thats not bad. right now mine is probably 80 city 20 hwy and I am at 14.7. next time you are cruising on the hwy try 65-68 mph and see what you get, I get 21-22 at that speed. I also get a lot of people waving at me, must be my good looking truck LOL.
