During engine start in cold weather, the proper technique includes
Choices
starting at high RPM to clear out ice immediately.
High RPM with cold thick oil destroys bearings.
✓ preheating engine and oil if temperatures are below the manufacturer's recommended cold-start threshold.correct
typically 20°F / -7°C), priming per POH, starting at low RPM, and monitoring oil pressure (must be in green within 30 seconds). Cold-start procedure: preheat (engine + oil) when below POH threshold, prime per POH (overpriming risks induction fire), start at low RPM (~800-1000), watch oil pressure — if not in green within 30 sec, shut down immediately to prevent bearing damage from cold/thick oil not flowing.
skipping the oil pressure check — it'll come up eventually.
Oil pressure check is critical — if not up in 30 sec, shut down.
leaving the master switch off until after start.
Master must be on for starter and instruments.
