The PACCAR MX-13 Engine: Why You Should Consider It? ›

The durability of Paccar MX-13 engines

The PACCAR MX 13 engine is renowned for its reliability and durability. Its robust construction and heavy-duty components ensure long-lasting performance even in the most demanding operating conditions.

The suit says that although PACCAR has touted that trucks equipped with the MX-13 engine would spend more time on the road and less time in the shop, the fuel injector issue has sparked “a multitude of problems,” including loss of engine power, shaking or vibration of the vehicle, engine knocking or detonation, lean ...

PACCAR engines are built to withstand the harshest conditions. The MX-13 increases its life to one million miles with any engine, placing it ahead of the competition.

The PACCAR MX-13 delivers consistent power and torque across a wide operating range — up to 510 horsepower with 1,850 lb. -ft. of torque. Fine-tuned to your precise operating requirements, this engine gives you more flexibility, more low-end power, higher fuel efficiency and a greatly enhanced driving experience.

Your Paccar engine can last for up to a million miles with the right maintenance and good mechanics.

PACCAR engines are known for their durability and fuel efficiency, while Cummins engines are known for their power and reliability. Ultimately, the decision between these engines will depend on the specific needs and preferences of the truck owner.

There are various tuning options available, ranging from custom Paccar tunes to pre-loaded options. Each comes with its set of advantages, and the choice depends on individual preferences and specific trucking needs.

The PACCAR MX-13 engine is built by PACCAR at their Columbus, Mississippi facility. From the CNC machining centers for engine blocks and cylinder heads to robotic assembly, MX-13 engines are manufactured to extraordinarily high standards.

New Paccar trucks face recall for steering control

Affected are PACCAR certain 2025 Kenworth K270, K370, T280, T380, T480, T680, T880, W900 and W990; and 2025 Peterbilt 220, 536, 537, 548, 567, 579, and 589 trucks. Owners are advised not to drive their vehicles until the remedy has been completed.

How often should you change the oil in a PACCAR MX-13? ›

Engine Oil Intervals and Specification:

Line Haul oil change interval is 40,000 miles when above 6 MPG. Vocational oil change interval is 25,000 miles (or 800 hours) and applies when fuel economy is less than 6 MPG and higher than 80,000 GVW.

The Cummins engine, which is a popular engine choice for heavy-duty trucks, has by far the finest reputation. Cummins engines are renowned for their dependability and effectiveness. The torque produced by smaller engines was insufficient in the past, but new developments have greatly improved this.

Cost Comparison: Rebuilding vs.

replacing a Paccar engine: Rebuilding a Paccar engine typically costs between $10,000 and $20,000, depending on the factors mentioned above. This may seem like a significant expense, but it can be more cost-effective than replacing the entire engine.

The B10 life of Paccar MX-13 engines is among the best in the industry. That's important because 90% of the engines will last a million miles before requiring a major repair. This gives it a significant competitive edge over competing engines on the market.

7YR/700K Mile Major Component Extended Warranty. Take advantage of a 7 year/700,000-mile extended warranty on major components for PACCAR MX-13 and MX-11 engines.

Usually, the number designation approximates the displacement volume. Paccar's MX-13 is 12.9L while Detroit Diesel's DD13 is 12.8L. This is not always the case, however, as the Mack Trucks MP8 is 13L. Simply put, the higher the displacement, the more power the engine outputs.

The PACCAR MX-11, designed for weight-sensitive applications, can now be spec'd with a higher hp rating up to 445 hp at 1,700 lb-ft of torque @ 900 RPM. The PACCAR MX-13 engine can be spec'd up to 510 hp at 1,850 lb-ft of torque @ 1,000 RPM.

The PACCAR MX-13 engine is built by PACCAR at their Columbus, Mississippi facility. From the CNC machining centers for engine blocks and cylinder heads to robotic assembly, MX-13 engines are manufactured to extraordinarily high standards.

While both options have their advantages and disadvantages, the decision ultimately comes down to cost. Here's a breakdown of the average costs of rebuilding vs. replacing a Paccar engine: Rebuilding a Paccar engine typically costs between $10,000 and $20,000, depending on the factors mentioned above.
