To ensure Cummins engines' durability, follow 10 key maintenance habits: religiously change oil/filter per specs, maintain fuel/air/cooling systems, conduct regular inspections, monitor gauges, manage idling, warm up/cool down properly, use genuine filters/fluids, and adhere to scheduled maintenance.

When sourcing parts for Cummins engines, choose among Genuine Cummins, OEM Branded, or Aftermarket. Genuine parts offer precision engineering, full warranty, and optimal performance. OEM Branded parts, from original suppliers, balance cost and quality. Aftermarket parts vary widely in quality, suitable for non-critical uses. Consider component criticality, warranty, emissions compliance, and TCO. Prioritize genuine or OEM for critical systems to ensure reliability and avoid risks.

Advanced diagnostics for Cummins engines involve ECM analysis via fault codes and live data, cylinder performance tests like power balance and compression checks, pressure/flow tests for fuel, cooling and boost systems, fluid analysis for oil and coolant, sensor/circuit checks, and visual inspections with borescopes/thermal imaging. These methods help pinpoint issues, enabling informed maintenance decisions and maximizing engine longevity.

Turbochargers and superchargers are forced induction technologies for ICEs. Turbos use exhaust energy, offering high efficiency but lag; superchargers draw power from the crankshaft, providing instant boost. Turbos dominate modern engines for fuel efficiency, while superchargers suit applications needing immediate low-end torque. Electrification and twin-charging are shaping their future.
