PACCAR has been a quality leader for over 100 years with a hard earned reputation for best-in-class reliability. The PACCAR MX is no different. When the engineers set out to build an engine worthy of the PACCAR name they began with the lofty goal of achieving a B-10 engine, an engineering standard requiring that 90% will reach 1,000,000 miles without requiring an engine overhaul. This is far higher than the industry standard of 50%. PACCAR spent $1 Billion and conducted over 50 Million real-world testing miles to ensure this is the most advanced and reliable engine on the road today.


The Paccar MX has Efficiency built in to nearly every aspect of the engine. From its extensive usage of Compacted Graphite Iron, and revolutionary Fractured Cap Technology, to its crankshaft without counterweights, and its unique lube module that extends service intervals to 40,000 miles. When it comes to up-time and operational efficiency, the PACCAR MX sets the standard.
