I have a 2015 Ram 1500 5.7 Hemi V8. I’m currently averaging 20mpg. Thinking of installing Cold air intake, Headers, and exhaust. Hopeful to get more mileage. Maybe enough to counter a 2” level kit with 33” tires... kind of sold on keeping stock height seeing your truck getting 27mpg. That’s amazing.

At 1 time, my 9 year old 5.7 charger averaged over 28 back and forth to work everyday. And I never use cruise control because the car is still just a joy to drive.

These is good trucks I have a stock 2023 Ram 1500 Limited with the 5.7L on stock 22s with the 33 gallon upgrade with a full 33 gallon tank I've been able to go 720 miles before refueling

I did pretty much what you did on my stock 2008 Ram 1500 5.7 hemi with mds, keeping it at 55-60 mph and got 27 mpg, which amazed me since normally I am lucky to get 20 mpg driving at 75mph. I attributed this to the lower speed, flat terrain, overdrive and the mds system which likely ran on 4 cylinders for the test period. Until your video I never mentioned it to anyone since I figured no one would believe a hemi could get such good mileage.

wow thats crazy! the most my truck has given is about 21 mpg. driving from LA to SD and i was doing the speed limit with little traffic. Thanks for the info and once again great content.

I'm averaging around 13 right now. 27 is great. I'd love even 20. Lol

Fun to watch the range INCREASE as you drive.

Most I got semi loaded on a trip was 27.3 with just a dry flow panel filter. 4x4 Express CC running 89 octane. My secret is keeping in ECO as much as possible. So hypermiling and cruise control as often as I can. Screw people who dont like it Im still doing 5-10 over like normal folks.

I’m pretty sure the wheels and tires and 93 octane is why he got such great mpgs. Not to mention power-mailing at 60 mph! Great test!

I own the same truck with only a kn intake and get about 24mpg on the highway using only 89 here in North Carolina. Love the vids man..keep it up!

Back up that same route he gets 7 mpg lol!!

Dude you were right down the road from me in Ennis 😄😄 I thought it looked like Texas 😎😎

I just bought a 2018 Bighorn 4WD with 90k miles. 3 weeks in I'm getting 21.5mpg so far with no mods

Though we like to top off as much as possible when filling up, I would not recommend filling up to the point that you can actually see the fuel in the filler neck. Depending on the vehicles emissions control design, I can cause issues with the emissions charcoal canister from the fuel sloshing into the vapor fumes line. I cant count how many times I've had to replace these for people due to this. just food for thought.

Hmm. I have a 2021 Ram 1500 5.7 Etorque. Did a 1500 mile trip 65-75 mph with some passing and got about 21 avg. If I slow down to 55-60 I'm getting closer to 24. I see guys with the 3.21 gear ratio get an extra 3-4 mpg.

Nice dude, thats a lot. I get about 15 MPG in my 06 GMC Sierra 1500 2WD V8 4.8L with a 34 gal tank, trying my best to get better MPG. Installed a cold air intake and bed cover but it didn't really make a difference sadly. I did install a heavier tool box though so maybe it just balanced out.

I hypermiled my 2022 5.7 eTorque 4x4 with 3.21 gears a few weeks ago and saw just over 30 MPG. I drove as slow as I could in 8th gear and hold it in high gear on level ground.

My 2018 ram 5.7 same specs stock will get 26 @60 and 19@75 the only things that should effect mpg positively would be a good tune after a cold air intake and exhaust upgrade. I love my ram though.

37 MPG!! Haha. 27 is great. I’m lucky to get 20.

4:14 ... PERFECT song syncing there with the speedometer lol

I averaged 23.4 MPG driving 1100 miles with my 2014 1500 6 speed. I could’ve done better but I got tired of driving like a grandpa 😁

Not to rain on your parade but leaving gas in the neck is damaging the fuel system 🤷‍♂️

I have a 2014 ram 1500 hemi with 3.92 and 8 speed trans. I get 18-19 every day driving around town and to work all stop and go lights etc. On the highway i get 22 mpg doing 70 mph on cruise control and 24 mpg if I set the cruise to 60 mph and 25-26 mpg if the cruise is set to 55 mph the only time I seen 27 mpg was on cruise control doing 50 mph going through vaginia everything is stock, stock 20 inch wheels stock height only mod I have is a S&B cold air intake. And I always run 89 octane and every 4th fill I run 91 to 93 octane. I also clean my fuel injectors every other oil change

My 2014 regular cab shortbox 1500 5.7 recently got 8.6 litres per 100 kilometers, which translates to 27.2 mpg. Completely stock.

Ditching that belt driven fan most likely netted you the biggest gain.

That truck is a unicorn, if fiat realizes that truck was sold to the public they’ll come knocking. ✌️

I Own a 2012 F-150 Lariet FX4 6.2 Ford Powered V8! 6.5 bed! 3:73 gear ratio! 6 speed automatic! 4WD! Ingot Silver paint! Platinum factory 2012 F-150! S&B Cold air intake! Pedal command! 3 inch Exhaust system! Super 44 flowmaster! resonator delete! 5 inch exhaust tip! Max towing 11,300 pounds! I get 12 city. Love my engine

I see “Eco” down there. Is that the same thing as MDS on our motors?

You didn't mention the green eco light which indicates that your engine is running on 4 cylinders instead of all 8 cylinders. Accelerate slowly so you can drive GREEN for the best mileage. Also, your tire pressure monitor was flashing. Better check your tire pressure. Low tire pressure will lower your gas mileage. Big Al

Can you comment a list of things that are installed?

On my new 2022 Ram 1500 eTorque V6 4x4 - I took it on a back road outside Colorado Springs to Elizabeth Colorado, a hours drive of about 54 miles with speeds from 45 to 55 mph and my fuel consumption rate as per computer was 31 MPG and back in Town got 23 using pump 87 Octane at Valero. I'm sure the 31 MPG is just a fluke and more likelihood of 29+ MPG I am keeping an eye on it Truck has 16,000 miles on it.

Use to drove semis and Some had this type of thing on them and I could get 90 mpg going down hill

You guys are lucky as hell to even get 20. Hell, I'm lucky to get 14-15. Bad idea lifting these girls.

On my Silverado: K & N cold air induction Flow master cat back exhaust Removed mechanical fan & replaced with flex-a-lite electric fans Not only quicker but increased my MPG

2 wheel drive makes a big difference I need my 4x4 ram in mud where I live in the country town

I've been able to get around 19-20 MPG on the highway going 60-65 and not pushing the truck at all. It's when you go 80MPH where your MPG decrease.

Most every RAM 1500 V8 owner complains their fuel mileage compared to the EPA mileage. But almost every Ram 1500 sold with a V8 is equipped with 3.92 Axle Ratio, rather than the Standard 3.23 Axle which is how the truck is equipped for the EPA Fuel Milage Test. The 3.92 gives the truck a Higher Towing Rating and it can be equipped with a Electric Locker Rear Axle. It also makes for quicker acceleration. The 3.23 Cannot be equipped with the Electric Locker (No reason given) the Towing Rating is lower and it accelerates slower. The 3.23 axle compared to the 3.92 axle results in a Engine RPM Reduction of 22% which equates to lower fuel consumption at any given vehicle speed, less engine wear and less engine noise. So unless you are towing heavy loads, or drag racing, RAM sold you a axle ratio that hurts fuel efficiency, but the EPA Rating looks good for advertising. Personally, I find RAM ‘s method of Ignoring the Intent of EPA rules to be Unethical. No Where in RAM advertising is it mentioned that the Costly Optional 3.92 Axle Ratio WILL Increase Fuel Consumption, making it even more Costly to the Buyer and Harmful to the planet.

Nice no doubt these hemi can get great mpg. In my 09 hemi crew 4x4 the highest I've ever got was 24mpg but took a pic of it at 23 or so. That was all stock 20in wheels. But now with all terrains on the 20s dropped to 16 if I am very very gentle with it.

My 2015 5.7 with 3.92 gears and an 8 speed transmission with 85k miles was averaging 12 mpg I added royal purple gas treatment to 20 gallons of gas sea foam to the oil and sea foam spray to my intake and my average went up to almost 14.5. I have an aftermarket exhaust and k&n air filter. Maybe you guys getting low mpg would benefit from gas/oil/intake cleaners.

Have a 2017 RT getting 18.5 City driving with 392 gears 285 / 50/ 20s on regular gas. Sweet Thunder Exhaust K&N cold air intake catch can only modifications. 9000 miles on truck with synthetic oil. Drive with a heavy foot love the sound and performance. 😁

I get 10.4. in my 05 1500. I envy this so much..

I average a solid 17.5 or so. Mines still being broken in though... And it's 4x4 with a higher factory ride height (according to the build sheet).

I need to do this kind of test on my ecodiesel . Best i got so far was 31mpg on 120mile run driving 75mph. Usually i average 27 on a tank mostly freeway 78mph. My truck configuration 2016 4x4 on 20s with air suspention. Never tough hemi will get this kind mpgs. Our current gas prices $3.50 for reg. $4.00 for diesel.

Had a 2014 1500 5.7 w/ mds and got 31mpg from Dallas to Lake City CO up in mountains no cruise On way back and down used cruise almost whole trip and got about 25mpg Usually got about 15 normal driving around town Have a 2019 Rebel with etorque now and lucky to get 17 hwy and 14 town

Nice truck! BTW 👍👍

Can't you screw up your gas tanken stuff by overfilling it... I thought there were sensors in there that were supposed to help since oxygen and stuff in stuff and by overfilling the crap out of your gas tank you actually followed those sensors and can screw them up I could be wrong this is what someone told me I don't know if it's true or not

I get 7.5 in town and 11 highway, 97 chevy silverado 5.7 V8 true dual catless exhaust strait pipe

*Cries in 13.1mpg with a level and 35s*

Goes to show ya, how you drive has a huge impact on mileage.

Yo Buddy - what state are you in again? Crushing it with this channel, keep it up

I get about 23-24MPG through west virginia, Ohio/Indiana im around 26-27MPG with MDS on and staying under 70MPH. totally stock other than 185 thermostat

27mpg highway should be the title

I got 28.5 when driving back from Georgia with my bone stock 19. That was going up the mtn too but it was at night and no traffic

Good work!

Now to back up that hill

Damn! My Subaru 4 banger only averaged 26 combined. I could get 31 mpg on the highway if I kept my foot out of it. That's damn good for a truck of any type.

I'd really like to do the electric fan mod on my 2018 but I want to make sure it doesn't harm the truck in any way. Is it cooling correctly or does the computer need to be tuned for the change in fans? Great channel btw. Keep it up! I'm sure you don't always overfill your tank but I figured it would be a good idea to mention that overfilling your fuel tank can damage your fuel system. You should only fill your tank until the fuel pump clicks off.

Got a '16 1500 4x4 with 5.7 a year ago and can easily get 20+ daily if not idling to warm in W. NY winter.

Anyone know if that gauge cluster is compatible with a 2014 Express?

That engine temp is hot!!

Ummmm dont think so. Fill up at same pump, same way you (IE: stop on second pump cut off) drive at least 100 mile loop, go back to the same pump and repeat fill up. Will get an accurate hand calc that way. Unfortunately most tuners screw up the onboard mpg gauge. I think they do it deliberately as if no one hand calcs and would believe the now inaccurate mpg gauge. Superchips may be one of the few that doesnt do this. Its good to see someone doing mpg videos , I always thought MDS was a good idea despite many people disabling it. EFAN and exhaust will definitely improve mpg.

Basically keep your rpms under 2000

Layer tell me how many miles you can run with a full tank and drive like normal people no like old man because my truck with full tank make 320 miles

I've done this test and seen a few others kn youtube do it in a ram. I find the dash is almost spot on if all highway. Start mixing city driving, work commutes, etc it starts to lie. I pulled off in my 3.21 ram going 60 mph for 90 miles, 26 mpg from my family's land west of Weatherford all the way back to my home in frisco, tx area. Dash was spot on. Now my work commute and a whole bunch of other random trips to the grocery store, etc says I'm getting 17.5ish. Driving grandpa style this tank in reality got about 1.5-2 mpg less then what the dash was saying. Pretty crazy, I was in the high 15s-16mpg. All highway she's accurate most the time from my experience. I really want to do the fan mod, and the shorty's. I just hate to mess with the grill shutters and I dont want to spend all the money on a tuner to adjust the fan temps and all that. I just added a drop in k&n filter and I can tell that the truck does not feel as bogged down in mds mode as it used to, just from a drop in filter... also about 1-2mpg better on the highway.

This doesn’t seem to far fetched because you were going like 60 or less and were babying it. Wonder what you get on more combined trips. My crew cab, 3.92, 4wd with 34” tires averages 17 MPG unmodified. I gas it here and there and usually am something over the speed limit not wildly over though.

Very impressive. :)

He probably has it in eco mode because my 3.6 journey is getting 14 city right now and i be hitting it like its a hemi

All vehicles are designed to get best gas mileage at 55 mph.

I get 10 😁

I’ve got a 2014 ram 1500 5.7l 4x4 with a 4 inch lift and on 35’s plus loaded with tools and I get 12-13mpg

When I had my 14 Sport was lucky to get 20 MPG and that was with a 91 octane tune and CAI and Spintech exhaust also drove it like an old man lol. My 17 High Country 6.2L is getting 23 MPG and it's stock other than a ported Katech throttle body and once got 26 MPG crazy.

I have a 2017 with 3.21 4x4 with 8000 miles and I drive it easy and mostly highway miles and when I check it at the pump and I have multiple Times the best I have ever got is 21 mpg and I’m always 1 or 2 mpg less then what it shows on the dash

I’m getting 30-32mpg@65 cruise with a ‘18 ram 1500 reg cab sb. 2wd, 5.7, 6 speed .3.92.....

my little frontier gets 18 for a full sized truck 25mpg average is amazing !

Which model of k&n cold air is it? I keep seeing conflicting info on a CAI giving better milage, buy I drive enough that it's worth a shot. Im torn between the 77 series and the 63 series. Also thinking a tuner might be a better choice for a first mod.

I was getting about 21 MPG in the summer but now that it's -16 f I'm getting around 17. I put in one of those fancy k&n filters also that has less restriction but doesn't seem to help in the winter.

I'm at 10.5 mpg right now. Seeing this is crazy. 2010 Ram 2500. Is there anything I can do to improve it?

Awesome. I just picked up an Ecodiesel. Kept going back and forth between that and the 5.7. Excited to see what I get. Its used and has 20" rims and 37" tires. Hoping to get between 23-25mpg with the lift. :)

Gas is at $4.20 in Texas today(5/18/22)

I used to test a product for MPG on several different brands and models of vehicles. You need more than 50 miles for an accurate calculation. do a full tank before doing the math. You'll also see how the difference in distance effects the calculations. We used a Lab in Ontario California to get official numbers for our product using a dynometer along with high tech equipment using EPA Standards for exhaust and MPG. (What the manufacturers use for their official MPG numbers) But they didn't go as I am saying using a full tank for their numbers (Real Life) but MPG does change using at greater distances compared to short runs because of topographical differences. That's why people rarely get the official MPG numbers put out by the manufacturer. its all LAB controlled test results It might not be that significant but you are a detail oriented person and did notice a difference topping it off across the street so I thought I'd point that out. I don 't even get half of what you showed here but mine is an 07. the biggest fail on that besides the exhaust is the slider window leaking filling up the two bowls under the seat meant for storage. I've been stuck on KZfaq for like 3 hours watching your videos, I agree with everyone else, your very talented in "how to" video production. Thank you

My 2015 ram avg 13mpg no matter what, driven it four years now. Noone has a solution. 80k miles on it. I'm looking for help

just bought a 1500. This is gonna be great for $7/gal coming up :D Gonna try and see what i can do to get 27 too

I squeeze 20-22 mpg here in eastern canada and thats usually running 62 mph..I dont tow or nothing with mine ,its an a-b kinda deal and a lil fun now and then..No custom tune but i am useing 91 oct with a trinity can tune...A throttle body upgrade and a muffler thats it for mods..Ill pull the fan off for now and see..

Noticed your tire air pressure was low, at least I believe that is what the trouble light was. Doesn’t that affect mileage as well? Seems like low pressure would result in lower mileage. Idk 🤷‍♂️

That’s crazy same mileage as my mazda

Did you adjust for the change in the tire size when using the 17" wheels? The 20's have a slightly larger tire diameter.

My completely stock 2016 hemi gets 13 on highway going 65 with cruise. I can never get good mileage out of it. Thinking about selling

Wait, don't those new Hemis go down to 4 cylinders on the highway? You will never see that kind of mileage on the older Hemi's.

I get 40mpg on my eco diesel 2021 with 4.88 gears on 38x14.50R26x14 8inch lift tune

This engine has cylinder deactivation tech.. whenever you see the green "ECO" in the lower left corner, it running in 4cyl mode .. won't see this on pre 2009 Hemi's

Awesome! Any idea if this works on 2019 5.7?

I have a 2016 Ram 4*4 level on 22*12 on 33s and I’m averaging 11-13.4 mpg smh

2017 5.7 4x4 express 8spd 150 mile trip varying from 80-90 avg 17.5mpg

I put new exhaust system eliminated muffler. I got 27.1 doing average 60 - 65. Was on flat terrian for most part with a tail wind. Getting 18.3 in town

It was interesting to see.

I have been looking at the E Fans. What type did you install and where did you get it from? I have a 2017 Dodge 2500 with the 5.7, 4” lift with 35” tires so I am trying to improve where I can

I'm getting around 16mpg daily commute, half of the trip is at freeway speeds. I took a 2400 mile trip and got around 21 mpg (all freeway).

27 mpg with a Dodge? 12 in town 15 on the highway!

Best method is to fill until pump clicks off and wait 30 seconds and pump until it clicks again and stop. This is the most consistent method of hand calculating your mpg

I can get 27mpg in my 2005 Ram 1500, but I have to do like 45 to 50 mph in high gear with MDS on. At 60mph I average 24 mpg. My overall average is usually 19 mpg. Unless I am aggressively driving then I get between 14 and 15 mpg average.
