Ram 2500 longbow crew cab with 6.4. Stock tire size but in Duratracs.


It gets its worse gas mileage boondocking in 4 lo.

I just got new tires and highway mph went to 22mpg. Almost affordable transport ; )

 

[anchorsaweigh]

...Is there something I can do to increase mpg?

Sure...buy a Prius...

First Ram 1 ton cummins, summer rural is 17-18. Longer drives 20-22. Average tank for life of pickup on simply auto is 17.19.

Second ram is a 2500 with a 6.4 It's 13-14 on average summer driving lots of turns and stops.

I really don't understand how my 22 Ram 1500 could possibly be getting worse city mpg than my worn out 99 ram high top conversion van with over 200,000 miles??? It makes no sense, Ram has better aerodynamics, newer engine technology, and 8,800 miles. I've always gotten at least the epa estimated highway mpg on anything I've drove besides this truck.

I actually have no idea what the avg mpg is on either of my trucks, nor do I bother thinking about it, it's a truck. I just put gas in it when I need too. I do know it uses a lot more when I'm towing the travel trailer - lol.

1) Gonna take a while for engine to break in. Mileage will improve some. STOP and GO in town will eat up the mpg's also.
2) You have the Bighorn, so I "assume" you have the SO motor not the HO motor.
3) My son on his 2025 Bighorn got almost 20 mpg traveling from NJ to FL and back with stops (running 89 octane gas). Motor still got a while to breaks in. the lie -o-meter will never be exact, once breaks in ok, should be within *** amount of mpg average, why U need to fill the same way, use same fuel octane and brand if possible for hand calc.
4) U may wanna think about changing oil and filter once U get some miles on the ride. With the double turbo engines, I would not GO OVER 5,000K on OCI, screw wat the manuals say and/or the oil meter. Rotate tires at 5K too. But for initial change I sure as heck would not go 5K.

All above IMHO.

I can get 20 ish on highway with cruise on. But towing my Stock trailer with loaded hay, 6000 lbs and/or more, I drop to 12 mpg or less, LOL. But I do have a new than in 2019, 5th Gen truck, 5/7L VVT, no E junk, but I am running AT tires which will drop mpg 1 - 1 1/2 mpg than stock SRA balloons.

I did the first oil change at 580 miles, will do another at 5k miles.

Used Costco Premium for the first several tanks, but will switch to regular now that I have a baseline. After 5k or 10k miles I’ll run 3 tanks of premium again and see if there is a difference. I’ve had vehicles that liked premium in the past. We’ll see.

My 2.7 Eco-boost got noticeably better mileage after 10k but didn’t care whether I was running premium or regular.

Then drive your ecoboost every day and sell your truck to someone who understands that trucks don't get good mileage because of weight, gears and the rotating mass needed todo real work.

I have driven it for 65 k and hwy varies between 30 and 35 and it’s always the highlight of the drive. Lots of passing but it is good on gas
