Cummins Engine Tuned for Fuel Mileage! $1000's Money saved Yearly

[@chrishubbs8633]

I drive a Cascadia and last time I drove from Laredo to Toronto I got 8 mpg with a 37000 lbs. load. Cruze control the whole way. I just drive slower. Keep it under 65 and you’ll do good. I also start my day at 2 in the morning to get threw as many towns and cities before the 4 wheelers start slowing you down. I make more saving on fuel then I will with saving time. ( going faster to use less hours). I know some don’t like it this way but it works for me.

[@BukWildTrucking]

5.6mpg Hammer Down, Hammer Lane. Great Video

[@jacobswaim9778]

I run a 870 in an 07' 379. Deleted , tuned, aftermarket turbo,intake and exhaust. Open 7"" with single resonator. I pull sulfuric tanker and most mountain terrain in AZ, NM, NV,Tx Utah. Always at 79.800 I'm getting 6.8 to 7.

[@frankdiii1223]

Great advice. Plus it's easier on the engine and parts all the way around.

[@davidschabel7832]

Pulling rgn loaded, lucky to get 3 or 4 mpg, 80,000lbs on the trailer 14 wide, kill fuel mileage, traded every four years, with around 350,000 miles on the odometer, truck was worn out at 4 years, believe I loved rgn, did it for 26 years, pull toy here.

[@michaeldunagan8268]

An ISX15 with no DEF/SCR/DPF is illegal... Unless you're driving a fire truck... I'm not saying: I'm just saying.

[@kingminkhant]

I constantly gets 7.6 on my cm871 with non vgt turbo putting out 625hp . Run the same road every day with 35k. You left out one more important thing.. your EGT. I found that before pulling hills to keep turbo spooling at 20 psi will get you cooler EGT and engine run more efficient. Also you wants to be direct drive to be more efficient. My most efficient speed with 35k in the box came to 63 mph. Keep up the good work 💯

[@jameson6930]

Totally thought that MAKECENTS was dead wrong about cruise control but I humbly admit ol' boy was right. Tried it for a week and saw significant improvement. Foots tireder tho.

Cheers... I got a cummins isx 400 st (in México) tuned to 475 dump the vgt turbo and got a borg warner no wasegate all delete cummins tune Mpg 7.0 some times little more.. Is posible. But if you do 7mpg with all the emissions bull you are the man... And yes keep turbo psi down

Hello again Sammy I have the blue T 660 flattop parked by you at Louisville truck show. Now I am not tuned for fuel and set at 600 hp and 2050 tongue. Getting in the sevens. One trip stands out but is not the only one to achieve this, Iowa to Phoenix and back 8.235 mpg about 2,500 miles. Yes 80 k loads. Now I know not a hood truck but with this tune feel lucky. This was off miles and fuel receipts. Interesting note went through a couple thunderstorms so going wasn't perfect. But I did only idle for about 2 hours total on the trip, which helps. Now I did the numbers for the first 35,000 miles awhile back. Starting with the truck this past winter and learning it, I didn't do very well on mpg's in the beginning. That being said the 35,000 mile average was 7.137 mpg's. That is with more then 3/4 of loads at 80 k. Plus with my wheel base trailer gap is horrible. So part of my story so far with the truck. Not to bad for a hopped up ISX. Maybe it's all luck only time will tell.

My old truck was build for the best MPG it could get. Being a 1995, it has 2.93 gears. Along with a 10 speed Direct. And yes you have a lot of guys, that say a OD will get better MPG. But we know direct is the best for Fuel Mileage. 22.5 low pros. Its one of the single axle Dillard trucks. They pulled doubles with. Detroit 11.1 365HP, but man does it pull good for a low HP compared to today's trucks. They also ordered there trucks back then. With 4 fuel tanks 470 gallons of fuel on board. Will know next year, when we start traveling. As will be pulling our camper around with it. And going to see the Redwoods. Figure I can fuel up west of OK City. And run to CA and back to cheaper fuel. No buying that high $$ Ca fuel. My boost gauge grossing around 43K stays around 5 lbs. Hard pull with big grades still around 12lbs most time's.

[@vinnyddavis6328]

I’m new to your channel but I agree with about 80% of that it also depends on the type of trailer you pull and the weight of your load and in my case how wide it is I have done as well with pulling oversized loads if I pay attention to what I’m doing and the area I’m driving in

[@bigdaddy407]

Shut the music off when your talking.

[@cooltrkin]

Sammy I know you like the ISX, while my favorite Cummins is the N-14. Do a video comparing the two. I think you'll find the n-14 is a far superior engine. My 02 9200i if I kept it at 60 I got 8.5 with it. My sons 01 9200 got 9 with no emissions. So my 41 years of experience tells me do not buy newer than 03 trucks.

[@michaeldunagan8268]

I have a Cummins 14 also. Yes it is better without emissions and yes it is easier to work on. However, those ISX's run very strong-even if they will drop a liner or put a rod through the block or need to be rebuilt in 300,000 MI. Of the one I drove for a year in a ProStar in 2017 I think it was a 2014 ProStar with its ISX 15 rebuilt at 340k according to the owner, I think the ISX had more below 1,300 RPM grunt than my n14 does and I have 3.58 the one ratio rear end where this one was like a 3.27:2. I also have eaten 13 speed where the truck I drove was a 10 speed. I just know that if I'm in a hurry or if I'm pulling heavy that I start my shifts at 1400 RPM and bring them up to 1625. If I'm in more of a hurry like pulling out front of traffic I'll start my shifts at 1500 and pull them to 1750. Bottom line: I have no problems driving an ISX15-I just have all kinds of problems ever owning one.

[@StickNclutch]

Cummins motors like to run at 55 mph So if you almost lug the motor like 1100 rpms before going to the next gear you can save too never floor it!...oh yeah floating gears never double clutch or granny shifting like a lot of guys do lol 😂

[@crawls70]

Athens, Ga here hammer DOWN

[@MakeCentsTrucking]

Go Dawgs!!

[@jonathanrabbitt]

He's right. In top gear, boost correlates directly with power demand (and hence fuel burn rate). Limiting boost, inherently limits fuel consumption. This is a similar notion to limiting cruising speed on flat terrain (aerodynamic drag being proportional to the cube of the speed, so limiting speed limits power demand). When in lower gears climbing steeper hills, you're better probably off lugging at higher boost than choosing a lower gear to get lower boost tho'. Engine efficiency increases with boost pressure.

[@michaeldunagan8268]

Uhm- -you're better off lugging.... Until you put a rod through the block! Maybe a Mac engine and maybe caterpillars and okay a Mercedes mbe4000 you can lug with impunity: but you're going to be spending 30 to 40 Grand very quickly if you try that with an ISX. Pittsburgh Power as pertains to climbing a hill says to be in a gear where you could increase your broad speed when you press on the accelerator. I climb mountains at 1800 RPMs and think nothing of it; that is where the rated horsepower is. Climbing hills cost money. Time is money and money is time; I don't want to spend 5 days climbing Monteagle.

[@Plowguitarist]

I have 550,000 miles on my ISX and pull it down to 1200 before I shift and have since new, just like cummins says to. I get 6.4 for the entire year. And I’ve had 0 issues.

I dnt have tht boost guage. I use the trip economy monitor that says "low Average High" i keep it over average. When going down hills i add speed because my truck can go to 80. Then i release throttle which helps me to climb over the hill with speed.
