Found oil under super charger can’t tell where it came from I see no leaks at oil filter housing?

What is your mileage? The supercharger has it’s own oil inside it, and is not part of the engine oiling system. The oil could be spilled engine oil from someone doing an oil change or the supercharger could be leaking oil.

If the supercharger has been recently removed then it is possible the small black plastic coupler underneath the supercharger was not replaced or is not seated properly, and engine oil is leaking from the top of the oil separator pcv housing.
