If it were going to sieze or show signs of wear and performance drop, i guess it would have shown it by now.
Ive run about 4 liters of 8% oil mix thru the engine doing hard vertical 60-100% throttle pattern manuevers with the setup (picture above). And its still incredibly oily inside and a little out. I wipe the oil after every 5 flights with a single small paper towel.. and most of what I wipe comes out of the carb venturi.
I have well over 80 hours on one of my glow 160fx with no performance drop but the wrist pin had seized in the piston and there was some wear on the big end. It still runs fine and I freed up the wrist pin.
Great to hear your engine is running well.
