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
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 LB. weight savings over 15 L. 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.
