If you read the very first post it sez: engine manufacturer International

 

What about MACK trucks? Do any companies offer those to lease or buy?

 

Things you'll learn. Was 15L engine without def too?

 

Explain

 

And what do you own now?

I've driven a few ISX.. better jake than CAT.. not smoother than an ACERT.. about equal in terms of hill climbing torq. CAT and Cummins are probably the only 2 engines I will ever own.

That said...

I recently had some heavy haul experience running a 2012 Coronado SD with a very under rated 600hp DD16. I routinly hauled 140 - 165k gross. That truck would have no trouble yanking the front wheels off the ground pulling a load. Most obscene amount of torq of any thing I've ever driven.

I've got 500hp and 1875 trq in my truck. Used to think I had a pretty stout motor till I ran that truck for a month.

How ever.. had some vibration issues between 1400 - 1500 rpm. Sucked down fuel like a new starlet on a casting couch.

None of the 475 - 525hp ISX I ran ever got over 6 mpg unless it was a very light load.

My truck started out rough at 4.5 - maybe 5 mpg on a good day. Now I see 5.8 mpg as a low pulling heavy with 6.2 - 6.5 mpg regularly. I have 150 gal tanks.. used to start looking for fuel after 800 mi. Now its nothing to look down and see 1000 - 1100 mi on the odometer and still be above 1/4 tank. Not as good as the newer Cummins or Detroits... but for a motor that will see 1million plus mi in between major mechanical repairs.. I am very happy with it.

None of the maxxforce engines had def. Navistar had to hire Cummins to show them how and help them design a system. That's why you can get Cummins in a Barnyard Buick

 

I've heard maxforce engines are bad. But is it all maxforce or just certain years or models ?

 

Sorry best CAT was the 1693.

 

Not currently a truck owner, but I plan to change that next year. Leaning toward Western Star and DD16 @560 or 600, but depends on what I decide to do work-wise. I had really good luck with the old 60 series in the 90s and early 2000s. That said, I also like Peterbilt and my kid has had really good luck with the Paccar MX he drives. Soooo....
