About the PACCAR MX-11
The PACCAR MX-11 is the smaller-displacement variant of the MX-13 (10.8L vs 12.9L). Introduced in 2016 for regional haul, vocational, and applications where the MX-13's full power isn't needed. The MX-11 offers significant weight savings vs the MX-13 — about 350 lb lighter — giving payload advantages for weight-sensitive operations. Common applications include regional fleets, dump trucks, and light vocational work.

Design and engineering
10.8L inline-6 — same architectural family as MX-13 with smaller bore and stroke. Same aftertreatment system. Lighter weight package designed for weight-sensitive applications.
Generations and emissions eras
Reliability and longevity
MX-11 has been more reliable than the early MX-13 from launch — PACCAR learned from the 2010-2015 MX-13 issues and incorporated improvements into the MX-11 from day one.
Common problems
Same family as MX-13 but at lighter stress levels. EGR cooler issues less common. DEF system maintenance same as all 2010+ diesels.
Maintenance schedule
Same as MX-13.
Pros and cons
✓ Pros
- • 350 lb lighter than MX-13 (payload advantage)
- • More reliable than early MX-13 from launch
- • Adequate power for regional and light vocational
- • Lower acquisition cost
⚠ Cons
- • Smaller power output limits applications
- • Smaller used market
- • Lower resale than Cummins L9 in similar applications
Resale value impact
Modest impact — MX-11 trucks have somewhat lower resale than equivalent Cummins L9 trucks but the gap is smaller than the MX-13 vs X15 gap.
