This can happen due to various reasons, its always due to poor installation. When the unit is running on low gas aka correct term refrigerant due to poor installation, the bottom of the compressor will be freezing cold, this causes the oil to mix with the refrigerant which is in a liquid state...

While it would be nice to make microprocessors. We should start making GaN, SiC mosfets, Capacitors. Why because these are used in every day modern USB fast chargers, Solar Inverters, EV, EV chargers, Laser, Fiber optic, wireless communication basicaly for both military and Civilian. Radars...

I am sure they did but it will take time for getting the know how there. Best time for China to take Taiwan is under Biden. The US military military is low on supplies. All the real patriots in the military officer core have been purged. You now only have officers who promote. LGBTQ etc. NSA...
