I fly a touring motorglider (Phoenix U15) with a 912ULS engine. Sometimes I'll soar with the engine off; other times, I'll soar with the engine idling for 2 or 3 hours at a time. I'm wondering how this prolonged idling might affect the engine.
Specifics:
The engine is two years old, with 230 hours on it. Idle on the ground is 1800, idle in the air is 2300, oil temperature and CHT are kept around 150 deg F using the cowl flap. It starts easily, runs smoothly, and the mechanic that maintains it says there is no evidence of any problems. Most of the time it's using 91 AKI ethanol-free auto gas.
