Some years ago I drove a 2011 Pete 386 with the MX 13 and a 13 speed. After going through some stupid emissions issues the company decided to do a delete. The mechanic knew me and decided that because it was only a matter of selecting the right settings from the dropdown menus that he would turn it up a bit for me. Not really sure what it was actually making but it went from splitting down or outright downshifting on every hill between des moines and KC to never having to touch the split. The only Cummins I've driven to run that way was a n14 redtop with a 18 speed.

[@theoregontruckerT880]

I’ve seen these Paccar MX engines really perform. A buddy of mine drives a single cab T-880 and pulls a 48’ trailer loaded with 27-30 tons of trash every single day and that thing for some reason gets up and goes pretty quickly, I think it must be the gearing like you say.

We got a pair of T8s with identical heavy spec builds.... one MX and the other with the Cummins.... and you're pretty well right about the nearly unnoticeable power difference. Same rears and EF18, but with the same load, on the same float deck, with full tanks and me in the seat of each, I had to go to the lowside and split down once with the Paccar pulling the same hill after hitting the grade at 70. Stayed on the Highside with the Cummins, but had an itchy finger and bad twitch in my thumb for the last couple of lengths.

Cummins is currently the only engines that can be completely maintained but the owner without needing to rely on shops or dealers. All software and service info is available. But those oil change intervals are both ridiculous. Especially on any engine with EGR. The soot that finds its way into your oil will slowly eat away at the insides. Bypass oil filters help a lot, but the only way to clean up your oil completely is to change it out often 10,000-15,000 miles depending on how high your fuel mileage is. It's a $40,000 engine, why are you going to neglect and abuse it to cut it's useful life in half?

I do miss my Cat. But Cummins all day long over the MX.

[@donbrown8494]

Owned and driven both the Cummins can get better fuel mileage with a PDI tuner then the MX and the Cummins tuned is strong the mx can not do what the Cummins will do no contest put the Amsoil by pass filter on the Cummins do the oil sample thing doing about 120 k miles to a oil change sample says oil is still good change small filter ever 30 k miles motor has 570k miles uses no oil and is super strong in the hills can do the East bound cabbage at 50 with gross 78k but the EGT temperature will make ya back out of it never use the mileage tune on my tuner just the power tune at 525 horse power tune I get over 8.3 miles or more all the time hits 9.5 somethings running empty drive 65 to 68 most of the time and will never ever buy a MX again had 3 mx this is my first Cummins run the fuel catalyst from Pittsburg power since new never had any DEF issues in 570k miles and never cleaned my filter tuner test alway says my before ash and after ash is still to factory specifications and the fuel additive helps keep my oil and dep filters clean really really the best money I ever spent was on my PDI tuner drove them all been driving since 1979 and a farmer hood oil and filters make a difference have a safe day and keep the shiny side up lol

I love my Cummings. Pulls hills and mnts great.

[@nathanhatcher7096]

My takes are cat and cummins and would have been a better comparsion! But i would take a mx over volvo any day if that helps!

[@veniaminpetrashishin9466]

Also one is qualified for remanufacturing while the other is disposable

[@Truckn_G]

My friend's company truck, a 2023 peterbilt has the paccar mx 13.it blew up at 88,000 miles. Meanwhile my 24yo freightliner fld120 with a 6nz cat is still going.

Scanias in the V8's producing 770 power as a base option that you can choose. And I think even a 500 HP V8 in a Scania can be ECU tuned up to 1K+.

[@thomaswilson8634]

Well I own a t680 with pacaar for all you wanna be haters. 710k miles and the only issue has been emissions same as all the others. Absolutely no engine problems. I had 2 international with cummings 500hp and both started using oil at 150k plus. Carbon packed.

[@sandasturner9529]

I call bullshit on those oil change intervals. Oil turns black before 40,000 miles

[@dancooney6529]

ISX Cummins all the way

[@johnhunter7244]

Important note: it is NOT compressed graphite, it is compacted graphite iron, which is just a different tyle of cast iron.

[@jamesalexander9342]

410 pounds on a semi isn’t really a selling point. And the extra 1 MPG gets beat out by reliability. So Cummins Everytime.

[@johnmclaughlin2845]

That’s amazing 60.000 miles oil changes ❤

[@kimdearrington258]

They both have their benefits, but I would bet that the graphite engine is much more expensive initially than the cast iron one, now that may not be the case as miles are put on them, but the benefit of the fuel mileage can't be ignored.

[@mikemcginley6309]

I ran the MX in two Pete's, and except for the DEF system never had a problem.

[@ismaelromero7842]

Majority of all the trucks i have driven over the years have been all cummins! big cam , n14 especially! recently switched to a paccar last year nothing bad to say about that diesel engine personally.. i ask for 24.5 tons every time at the quarry and it does its job everytime point A to point B with no problem

[@user-xg3jt3oj9v]

I was told that crap on a Detroit 60,smaller engine better fuel mileage 4.5 lol,went to cat c-15,could bank all day at 5to5.5 on fuel and more power

[@russellzuniga1234]

As a diesel mechanic on paper de MX sounds great but they have a lot of issues and they’re expensive to repair,just get the Cummins

[@Hwyman22]

That sound of the Cummins is worth the more $ alone

[@willmann30]

My 12.7 DDEC IV is sippin tea listening to this argument. It just group texted C15, N14, M11, D12 and Mack E-7 to listen in.

[@ernestosandoval2029]

The junk yard is full of those engines

[@terryswails1191]

Knock Like a Claterpillar, but I'll take the Claterpillar every time

[@jeepmanxj]

Reading through this comment section i realize people are trying to relate their light duty ego diesel in their pickup truck to these and have never ever had to deal with one

[@7thfloorisnomoreq790]

Well when you work on trucks everyday you know in this situation the cummins is the correct answer. But there are way better options out there

[@jnk26]

I would take either of them. I have been left on the side of the road more than 15 times between the two(2014 and 19 mx13, and many many ISX and X12 X15) if you are actually needing the 605hp/2050lbft power you dont get the mileage to support the 60k miles service intervals. Thats part of why I was left on the side of the road, companies are all about pinching pennies. 4.7mpg is the shortest OCI for both motors

[@seanmerisier1811]

Detroit baby, come to the bright side 👍🏾

[@Darkvirgo88xx]

The benefits of the MX are even close tp significant enough to pick it over the Cummins in my opinion and im not even a diesel guy. Im going solely off both their statements and the Cummins soundeds smoother while running to me.

[@codyleonard9798]

We have an X15 in our Wirtgen W200Fi and it sounds amazing
