Paccar vs Cummins

I think your last sentence says it all.
You hated it before you ever drove it.
And you drove it accordingly.
See it more then once here on TTR.

 

Well, please explain to me what I did wrong then when driving it. If a truck won’t pull a load well, it’s under powered or not set up correctly. I typically am top in our fleet in the fuel bonus program, my Volvo rarely had issues. If you were to call Ryder and ask them for the write ups on the Freightliner I just started driving, you would know I am not a steering wheel holder type. I catch a lot of things because I inspect my trucks thoroughly.
I have worked on and operated 3406B cats, N14 Cummins, DDEC 3 500, D13 Volvo. Of all these motors, the Paccar was the weakest and had the most issues. If the emissions were removed, and the timing advanced and the ecm reprogrammed, it would probably be a good motor.

 

And for the record, I don’t run rpms up to 1600. I rarely go past 1300 until I get to 8th or 9th. I just had to run those Paccar motors to 1600 to get up to speed.

 

My brother in law runs a private fleet of over 800 units. They have every brand and type of truck. They will NOT buy or lease anything with a Pacar motor for the last 3 years.

That should count for something?

 

I've been hearing some good things lately about the MX engine from Paccar but maybe im a little biased because it was in my first PB 579. It got the job done and I never really had an issue with the motor. I've also driven the cummins engine and it did just as well. Seems to be more of a personal preference on which specs you prefer.

When I bought my PB 579 from a paccar used truck center I had the same question about which engine I should get and steve from the dealership sent me this article so I could see the engine in depth: The PACCAR MX-13 Engine | PACCAR FINANCIAL Used Truck Center

 

I would love to hear a current update on your MX thought. Looking at a couple of 2015s KW T660, 450-525 mile range, at dealership that has gone through them. Come with one year warranty. I am currently running a E7 460 w/13 speed. Just looking to get something a little newer.
