MX-13

High Performance Redefined

The Paccar MX-13 12.9 liter engine features enhanced durability, reduced complexity, performance upgrades, increased downspeeding capabilities, and more efficient combustion.

Quality We Stand By

Engines are more than a tool to move your trucks forward – they are the beating heart. Every PACCAR engine is meticulously designed for maximum power, performance, and efficiency in mind.

MX-13 Capabilities

Uptime

MX-13 engines are built for durability, with multi million-mile endurance testing. Every MX-13 comes standard with remote diagnostics to deliver focused uptime support.

Excellent Fuel Economy

Fuel savings is one reason the PACCAR MX-13 continues to gain popularity in the heavy-duty market.

Low Cost of Service

Low cost of service with up to a 75,000-mile oil change interval, MX engines will save your business money due to the low cost of routine maintenance over the life of the engine.

Weight Savings

Less engine weight means hauling more payload with every trip. The PACCAR MX-13 engine provides truck owners up to a 450 low bed weight savings over 15 liter. engines.

Superior Performance & Quiet Operation

An MX engine has broad torque curves, so it requires less shifting, and the quiet operation improves the driving experience.

Built For The Long Haul

The PACCAR MX-13 Engine is built for the long haul. No matter what the conditions, this engine will get you to your destination with power to spare.
