info: paccar mx 13

That's never good when there ain't no comments at all

 

we have two in dump trucks pair up with allison trans and they have really nice power. Both drivers love them.

 

Gutless.. Worst engine ever made. I can pull the truck harder than the 12.9 liter.

 

The older ones tend to be hit or miss.. lots of improvement for the newer ones. In the hands of a good driver, you can get good fuel mileage out of them. Same Variable Geometry Turbo and aftertreatment system as what the Cummins uses. Davie 4 software is a pain in the nuts. They seem to need computer updates fairly often, but the bugs seem to have gotten worked out of them, for the most part. Not a powerhouse, by any means. Cruised extremely low - more so than even a Cat engine. Don't wanna shift by sound until you get used to that engine.

 

The last couple of years, one of the brokers I haul for, has bought the 5 new petes with paccar MX13's. The ones that have hit 200,000 miles have been more in the shop for DEF sensors issues than on the road, which are 2 of them. No warranty on DEF issues.
