Reliability and Power

Text for the video

For long-haul trucking, durability isn’t optional—it’s essential. The Caterpillar C15 engine stands out as a staple of power and reliability in the industry.

Launched in the early 2000s, and evolving from deep roots in Caterpillar engineering, the C15 delivers up to 580 horsepower and over 2,050 pound-feet of torque, with a sturdy 15.2-liter inline six-cylinder design. Advanced electronic controls optimize both power delivery and fuel efficiency, making the C15 a favorite for demanding, heavy-duty trucking.

When it comes to maintenance, the C15 is designed for straightforward service. Routine oil and filter changes every 25,000 miles, and easy access to key engine components, keep these engines running reliably mile after mile. With proper care, it’s common for a C15 to exceed a million miles with its original block.
