- Record load, rpm, fuel burn, and temperatures on a regular schedule to spot changes early.
- Keep fuel clean: drain separators, monitor filters, and avoid running with restricted elements.
- Stay current on cooling system service—scale, growth, or low flow quickly impact a high-speed engine.
- Use approved oils and coolants; send oil & coolant samples for trend analysis on commercial duty cycles.
- Address alarms immediately—ignoring fault codes on a common rail system gets expensive fast.
