PACCAR MX Rigorously Tested

Service Shop Open Truck Hood

PACCAR MX engines are designed with an industry-leading B10 life. That means 90 percent of the engines will reach 1 million miles without needing a major overhaul. That’s a big competitive advantage over other engines on the market.

The rigorous tests done on these engines help validate that they meet the test of time for their first owner, as well as their second. Before a PACCAR MX engine is put to work in a truck, the design has gone through countless hours of testing to ensure quality, performance and a best-in-class service life.

While PACCAR puts together a great engine, it also tears them apart. There’s learning that happens when engineers take apart an engine with a million-plus miles. Being this thorough allows engineers to look at individual components to see how they’re holding up and spot possible areas for improvement.

What’s in the future with the PACCAR MX engine? Continued leadership and continued improvement. The MX is known for quiet and smooth operation, durability, fuel economy and its power curve. It’s the recipe for success for fleets looking for high performance.
