2500 is just too heavy to get 20+ mpg on a hemi.

I have a 2010 ram 2500 5.7 . I read about guys claiming to get 20+ miles to the gallon which I kind of doubt but is there anything I can do to increase mileage... such as would upgrading to a newer 6 speed trans help?

I get better mpg when outside temps above 80 degrees.

not even close to the op's ?.my bone stock 2500 /5.7 with i think had the 6 speed,can't recall, with stock size tires never once got anywhere near 20 mpg hwy or city downhill with a tailwind.skinny stock tires and as little weight as humanly possible may get you 12 to 14.or you can get a cheap commuter 4 banger car.
I get that...when I quoted the other poster, he had said that no 2500 will get 20 mpg. I agree if that 2500 has a hemi. I disagree if that 2500 has a cummins, 20 mpg is very doable.

Just do what the guys you refer to are doing. ( assuming they are driving gasoline powered trucks ) Just tell yourself you are getting 20+ MPG on a routine basis and believe what you tell yourself. What you cannot do is take a long highway trip at 55MPH with a horrendous tailwind and level terrain, compute the fuel mileage for that one trip and call it your overall average for thousands of miles. Good luck with however you decide to handle it.
edit: And don't believe the "Lie-O-Meter

On my '15 2wd 1500 8 spd 3.21 with the Hemi, my evic usually shows about 1 mpg higher than hand calculated.

Most of my miles are a good bit of stop and go, 26 miles to work, about 6 miles of which is interstate. My evic will usually be at ~19.7mpg.

Traffic really sucks in my area of Flatistan, as everybody seems to be moving here to escape the more liberal areas of the country.

On road trips in the SE US, the evic has gone as high as 24 mpg, with hand calc at ~ 22.5 mpg.

My truck is bone stock, except for LT "E" rated tires, which did lower my mpg a little compared to the stock SR-A's. It is a truck, it should have truck tires, IMO.

I do like to use the skinny pedal from time to time, so that will pull my numbers down a little bit, but I can usually keep my evic at or near that 19.7 mpg if I go easy on the skinny pedal. Have 141,000 miles now, and use 87 gas exclusively.

I am running a 2021 2500, 6.4 with 8 speed and 3.73 gears. I have got just over 20 a couple of times, but the long term average for city, highway etc is about 16 mpg. To get 20 on the highway I have to stay under 65 mpg, go easy on the go pedal and not have a headwind of any kind.

This is headed west through the mountains past Jasper Alberta after filling up in Jasper.

Trucks = enjoy consuming gas in mass quantities. Sorry, I’m not going to be someone who drives a truck to save on gas. Frankly, I don’t get it. If you want the best fuel economy, buy a Diesel, but the offset is the higher cost of maintenance So using a bit more gas, is it a push?

Just drive your truck. When gas is low, buy more.

If you want fuel economy, buy a Prius or a plugin that you charge at home. Forget a supercharger at 90% the cost of fuel.

Drive a small fuel efficient car.
It's a truck, built to do work.
If I need to conserve gas, I drive my beetle. If I need to tow or haul something (or just have fun) I drive my Ram. Yeah it costs over a hundred bucks to fill her up, but that's the price of driving a truck.

I was wondering if new Fuel injectors would help along with cold air intake. Problem is its a daily driver and I tow 7K trailer on the weekend's just trying to improve a little bit. I do plan on switching out the Trans to a more modern one when it's time but till then ...
