Paccar Engines

PACCAR engines are recognized for their quiet and smooth running, as well as their longevity, fuel efficiency, and power curve. It’s a winning formula for fleets seeking excellent performance.

PACCAR proudly makes four different types of truck engines, all of which are neatly designated in odd numbers depending on the capacity in liters of the engine.

Diesel fuel and maintenance are two of the most constant costs of transportation. Regardless of which of the two you despise more, PACCAR offers a diesel engine option for your truck(s) to keep your costs to a minimum.

The PX-7 is our best option if you have a medium-duty truck and want to save money on gas. There’s a good possibility you’ll want to opt for the MX-13 if you want a long-lasting engine. Then there are the two in the middle PX-9 & MX-11, if you want to cut your maintenance and fuel consumption expenditures across the board.

The PACCAR MX engine produces up to 485 horsepower and delivers outstanding performance across a wide range of engine speeds. PACCAR pioneered the design and production of high-strength compacted graphite iron (CGI) utilized in the MX engine block and cylinder head, in addition to performance excellence.

Paccar Engine Reviews

Every component is planned and built to function in perfect harmony in Paccar Engines. The PACCAR engines have outputs ranging from 299 to 530 horsepower, making them excellent for long-distance coaches, as well as intercity and public transportation applications.

Several innovations on the MX engines are meant to increase performance and fuel economy. Oil filtration and temperature controls are integrated into the lubricant module & variable displacement oil pump, which increases uptime and improves serviceability. 

A new single cylinder air compressor and variable speed coolant pump are available on the MX-11 and MX-13. The fuel system combines high pressure with a common rail system, resulting in improved combustion, increased fuel economy, and lower noise and pollutants. With peak torque of 1550-1850 lb-ft at low RPM, the engines are sure to provide more low-end power.

PACCAR’s engine range is built to be tough and long-lasting. Both MX engines have been engineered to have a B10 life of one million miles, which is the best in the industry. PACCAR expects 90% of their engines to last one million miles before requiring a significant repair.

Are Paccar Engines Better Than Cummins

Paccar is far more dependable, plus they come with an extended warranty. Cummins has complaints like poor cams, terrible fuel pump pistons, carbon packed rings, and so forth. The Cummins engine offers higher horsepower but worse MPG. 

Paccar is a little less powerful, but it gets better MPG. The only disadvantage is that you will need to go to a Paccar shop for engine work, but since you have a guarantee, this will be free.


Engines are more than just a means of propelling your truck forward; they’re the lifeblood of the beast! Whatever engine you choose, it’s apparent that PACCAR considers the engine to be one of the most essential elements of the vehicle and takes great care in making it the best it can be.
