Preferred Partners Spotlight: Cummins X15 Efficiency Series

Cummins X15 Engine

Cummins is reinventing the heavy-duty engine category. The X15 Efficiency Series includes the most advanced fuel-saving features, so you get the most out of every drop of diesel fuel, from the optimized cam profile to a new piston structure.

The X15 now has some of the longest service intervals in the industry, helping you keep more of your hard-earned money. Oil drain intervals on this engine have increased to 60,000 miles in light duty cycles, and with the Cummins OilGuard oil analysis program, engines can extend to 80,000 miles between drains.

Other engine features include:

  • VGT Turbocharger
  • XPI Fuel System
  • Single Module Aftertreatment System
  • Fleetguard Fuel Filters and Lube Filters
  • High-Capacity Electronic Control Module (ECM)
  • Power Cylinder Improvements
  • Vehicle Acceleration Management (VAM)

The X15 offers highest fuel economy, and increases uptime for greater productivity and profits. Top it off with the best resale value of any engine in the industry, and you’ve got a total cost of ownership that puts you in front of your competition.
